Parapraxis: A Freudian Slip of the Tongue

A parapraxis, commonly known as a ‘slip of the tongue’, is a Freudian concept that suggests that these slips reveal important information about the repressed content of the unconscious mind. According to Freud, these mistakes are not accidental but rather a manifestation of the unconscious mind’s desires and thoughts. For instance, a person may accidentally call their boss by their partner’s name, revealing an underlying attraction of resentment towards their boss. Freud believed that these parapraxes could provide valuable insights into a person’s psyche and help uncover repressed memories of emotions. Therefore, he considered them an essential tool in psychoanalysis. Today, parapraxes are still studied and analyzed by psychologists and therapists to gain a better understanding of their patients’ unconscious thoughts and feelings.

Memory Forms

Memory is the ability to store, retain, and retrieve information. There are different forms of memory, including sensory memory, short-term/working memory, and long-term memory.

Sensory memory is the capacity for briefly retaining the large amounts of information that people encounter daily. It includes echoic memory (gathered through auditory stimuli), iconic memory (gathered through sight), and haptic memory (acquired through touch).

Short-term memory is the ability to keep a small amount of information available for a short period of time. Atkinson and Shiffrin’s multistore model (1968) suggests the existence of a short-term storehouse with limited capacity. Baddeley and Hitch (1974) further developed the concept of short-term memory, which eventually became known as Baddeley’s multi-storehouse model (2000). This model includes the central executive, visuospatial sketchpad, phonological buffer/loop, and episodic buffer.

Long-term memory includes declarative (of explicit) memories, which can be consciously retrieved, and nondeclarative (of implicit) memories, which cannot. Declarative memory includes episodic memory (stores personal experiences) and semantic memory (stores information about facts and concepts). Non-declarative memory includes procedural memory (recalls motor and executive skills), associative memory (storage and retrieval of information through association with other information), and non-associative memory (refers to newly learned behavior through repeated exposure to an isolated stimulus).

Overall, memory is a complex and essential cognitive function that plays a crucial role in learning, reasoning, and understanding.

The superego encompasses the ‘ego ideal’, which embodies exemplary attitudes and conduct. One can liken the Superego to a moral compass of conscience.

Freud’s Structural Theory: Understanding the Three Areas of the Mind

According to Freud’s structural model, the human mind is divided into three distinct areas: the Id, the Ego, and the Superego. The Id is the part of the mind that contains instinctive drives and operates on the ‘pleasure principle’. It functions without a sense of time and is governed by ‘primary process thinking’. The Ego, on the other hand, attempts to modify the drives from the Id with external reality. It operates on the ‘reality principle’ and has conscious, preconscious, and unconscious aspects. It is also home to the defense mechanisms. Finally, the Superego acts as a critical agency, constantly observing a person’s behavior. Freud believed that it developed from the internalized values of a child’s main caregivers. The Superego contains the ‘ego ideal’, which represents ideal attitudes and behavior. It is often referred to as the conscience. Understanding these three areas of the mind is crucial to understanding Freud’s structural theory.

Ribot’s Law and Jost’s Law: Understanding Memory Consolidation and Forgetting

Ribot’s Law, also known as the law of retrograde amnesia, suggests that recent memories are more likely to be lost than older ones. This implies that memories need time to consolidate and become more resistant to forgetting. Ribot observed that people who experience traumatic events often lose memories leading up to the event, but older memories are preserved. This pattern is also observed in patients with Alzheimer’s disease, where the saying goes, you lose first what you learn last.

Jost’s Law of forgetting complements Ribot’s Law by stating that if two memories are of the same strength but different ages, the older memory will decay more slowly than the younger one. Together, these laws suggest that memory consolidation is a gradual process that takes time, and once memories are consolidated, they become more resistant to forgetting. Understanding these laws can help us better understand how memories are formed, retained, and lost over time.

The Significance of the Declaration of Helsinki in Biomedical Research Ethics

The Declaration of Helsinki, created by the World Medical Association in 1964, outlines the fundamental ethical principles that govern biomedical research involving human subjects. Over the years, it has undergone several revisions and continues to serve as a cornerstone of good medical practice. Its importance lies in its ability to provide a framework for ethical decision-making in research, ensuring that the rights, safety, and well-being of human subjects are protected. The Declaration of Helsinki is a crucial document that guides researchers, clinicians, and policymakers in their efforts to conduct ethical and responsible research.

Ethical theory and principles are important in medical ethics. There are three key ethical theories that have dominated medical ethics: utilitarianism, deontological, and virtue-based. Utilitarianism is based on the greatest good for the greatest number and is a consequentialist theory. Deontological ethics emphasize moral duties and rules, rather than consequences. Virtue ethics is based on the ethical characteristics of a person and is associated with the concept of a good, happy, flourishing life.

More recent frameworks have attempted to reconcile different theories and values. The ‘four principles’ of ‘principlism’ approach, developed in the United States, is based on four common, basic prima facie moral commitments: autonomy, beneficence, non-maleficence, and justice. Autonomy refers to a patient’s right to make their own decisions, beneficence refers to the expectation that a doctor will act in a way that will be helpful to the patient, non-maleficence refers to the fact that doctors should avoid harming their patients, and justice refers to the expectation that all people should be treated fairly and equally.

Understanding Grief: Normal and Abnormal Phases

Grief is a natural response to loss, and it is a complex process that can take different forms and durations. John Bowlby and Kubler-Ross have proposed models to describe the typical phases of grief, which can vary in intensity and duration for each individual. Bowlby’s model includes shock-numbness, yearning-searching, disorganization-despair, and reorganization, while Kubler-Ross’s model includes denial-dissociation-isolation, anger, bargaining, depression, and acceptance.

However, some people may experience abnormal grief, which can be categorized as inhibited, delayed, of chronic/prolonged. Inhibited grief refers to the absence of expected grief symptoms at any stage, while delayed grief involves avoiding painful symptoms within two weeks of loss. Chronic/prolonged grief is characterized by continued significant grief-related symptoms six months after loss.

It is important to distinguish between normal grief and major depression, as a high proportion of people may meet the criteria for major depression in the first year following bereavement. Some features that can help differentiate between the two include generalized guilt, thoughts of death unrelated to the deceased, feelings of worthlessness, psychomotor retardation, and prolonged functional impairment.

Overall, understanding the phases and types of grief can help individuals and their loved ones navigate the grieving process and seek appropriate support and resources.

Depression (Brown and Harris)

In 1978, Brown and Harris conducted a study on 458 women in the inner London area of Camberwell to investigate the causes of depression. The study resulted in the development of a model that identified four vulnerability factors for depressive illness in women. These factors included having three of more children under the age of 14 at home, lacking an intimate relationship with a husband of boyfriend, lacking employment outside of the home, and experiencing the loss of a mother before the age of 11 years. The model emphasized the role of psychosocial factors in the development of depression.

Ribot’s Law is the only law among the options provided, the others are non-existent.

Temperament is the innate aspect of an individual’s personality that is believed to be influenced by genetics, while character is shaped by learned experiences. Thomas and Chess developed a classification system that assesses children’s behavior based on nine traits, including activity level, adaptability, and emotional response. They found that 65% of children fall into one of three temperament types: easy, difficult, of slow to warm up. Thomas and Chess also introduced the concept of goodness of fit, which refers to the compatibility between a child’s temperament and their environment. When there is a good fit, children are more likely to reach their potential. For example, teachers can provide active learning experiences for children with high activity levels instead of seat work.

The origin of the term dementia praecox is a topic of controversy. While some sources credit Kraepelin with popularizing the term, others argue that it was first used in its Latin form by Arnold Pick in 1891. The original term demence precoce was coined by Morel in 1852. Despite this, the College has chosen to attribute the term to Kraepelin. Therefore, if the question refers to demence precoce, the answer should be Morel, and if it refers to dementia praecox, Kraepelin should be selected.

History of Psychiatric Terms

In the exams, it is important to be familiar with the individuals associated with certain psychiatric terms. For example, Kraepelin is associated with dementia praecox and manic depression, while Bleuler is associated with schizophrenia. Other terms and their associated individuals include Hebephrenia (Hecker), Catatonia (Kahlbaum), Schizoaffective (Kasanin), Neurasthenia (Beard), Unipolar and bipolar (Kleist), Hypnosis (Braid), Group dynamics (Lewin), Group psychotherapy (Moreno), Psychopathic inferiority (Koch), Psychiatry (Reil), and Institutional Neurosis (Barton).

Flashbulb Memory

Flashbulb memories are vivid and detailed recollections of the circumstances surrounding a significant event. These memories are typically episodic, meaning they are focused on the specific details of the event rather than just the facts. One example of a flashbulb memory might be recalling where you were and what you were doing when you first heard about the death of Princess Diana in 1997. What sets flashbulb memories apart from other types of memories is the high level of emotional arousal that accompanies them. This emotional intensity helps to cement the memory in the mind, making it more vivid and long-lasting.

Throughout childhood, there is an increase in working memory capacity. Additionally, research has demonstrated that working memory performance can be enhanced, particularly in individuals with ADHD.

Memory Forms

Memory is the ability to store, retain, and retrieve information. There are different forms of memory, including sensory memory, short-term/working memory, and long-term memory.

Sensory memory is the capacity for briefly retaining the large amounts of information that people encounter daily. It includes echoic memory (gathered through auditory stimuli), iconic memory (gathered through sight), and haptic memory (acquired through touch).

Short-term memory is the ability to keep a small amount of information available for a short period of time. Atkinson and Shiffrin’s multistore model (1968) suggests the existence of a short-term storehouse with limited capacity.

The Sally-Anne Test and the Theory of Mind

The Sally-Anne test, conducted by Simon Baron-Cohen, led to the development of the theory of mind idea. The experiment involved several groups of children, including those with autism. During the test, a skit was performed where Sally put a marble in a basket and left the room. Anne then removed the marble from the basket and placed it in a box. When Sally returned, the children were asked where she would look for her marble.

The results showed that most non-autistic children correctly identified the basket, while most autistic children pointed to of named the box. This led the researchers to conclude that the autistic children who chose the box lacked the ability to understand that Sally did not know the marble was in the box. The Sally-Anne test thus became a crucial tool in understanding the theory of mind, which refers to the ability to attribute mental states to oneself and others.

Maslow’s Hierarchy of Needs is a theory of motivation introduced by Abraham Maslow. The hierarchy consists of five levels, with the most basic needs at the bottom and the most advanced needs at the top. Maslow proposed that a person would only become concerned with the needs of a particular level when all the needs of the lower levels had been satisfied. The levels include physiological needs, safety needs, social needs, esteem needs, and self-actualization needs. Maslow also made a distinction between D-needs (deficiency needs) and B-needs (being needs), with B-needs allowing us to reach our full potential but only after D-needs have been satisfied. Later in life, Maslow expanded upon the model and included cognitive, aesthetic, and transcendence needs, resulting in an eight-staged model. The cognitive needs include knowledge and understanding, while aesthetic needs involve appreciation and search for beauty. Transcendence needs are motivated by values that transcend beyond the personal self.

According to Freud, the mind can be divided into three parts: the id, the ego, and the superego. The id is a collection of instinctual drives that are not organized and are controlled by the primary process. The id lacks the ability to delay of modify these instinctual drives that an infant is born with. The ego operates in all three dimensions of the mind: conscious, preconscious, and unconscious. The ego is responsible for logical and abstract thinking, as well as verbal expression in the conscious and preconscious parts of the mind. The superego is responsible for creating and maintaining an individual’s moral conscience based on a complex system of values and ideals that are internalized from parents. The terms unconscious and preconscious refer to Freud’s model of the mind, which includes the unconscious, preconscious, and conscious parts.

Stigma is a term used to describe the negative attitudes and beliefs that people hold towards individuals who are different from them. There are several types of stigma, including discredited and discreditable stigma, felt stigma, enacted stigma, and courtesy stigma. Discredited stigma refers to visible stigmas such as race, gender, of physical disability, while discreditable stigma refers to concealable stigmas such as mental illness of HIV infection. Felt stigma is the shame and fear of discrimination that prevents people from seeking help, while enacted stigma is the experience of unfair treatment by others. Finally, courtesy stigma refers to the stigma that attaches to those who are associated with a stigmatized person.

Neo-Freudians were therapists who developed their own theories while still retaining core Freudian components. Some important neo-Freudians include Alfred Adler, Carl Jung, Erik Erickson, Harry Stack Sullivan, Wilfred Bion, John Bowlby, Anna Freud, Otto Kernberg, Margaret Mahler, and Donald Winnicott. Each of these individuals contributed unique ideas to the field of psychology. For example, Carl Jung introduced the concept of the persona and differentiated between the personal and collective unconscious, while Erik Erickson is known for his stages of psychosocial development. Margaret Mahler developed theories on child development, including the three main phases of autistic, symbiotic, and separation-individuation. Donald Winnicott introduced the concept of the transitional object and the good enough mother. Overall, neo-Freudians expanded upon Freud’s ideas and helped to shape modern psychotherapy.

Controversial studies in psychiatry have been a popular topic in exams. One such study was the Willowbrook School Study, where healthy children with learning difficulties were inoculated with hepatitis to assess the potential of gamma globulin to treat the disorder. Beecher’s study listed over 20 cases of mainstream research where subjects were experimented on without being fully informed of the risks. The Tuskegee syphilis experiment followed impoverished African-American sharecroppers with syphilis, and a significant proportion did not receive available treatment. Stanford’s prison experiment created a simulated prison environment where participants became their assigned roles, with guards becoming harsh and cruel to prisoners. The Tearooms Study involved Humphreys pretending to be a ‘watch queen’ to study men who have sex in public toilets, raising the issue of informed consent. Milgram’s Study investigated authority and obedience, where participants administered fake shocks to a confederate, with 30 participants continuing to administer shocks until 450 volts was reached. The Rosenhan experiment involved pseudopatients presenting themselves at institutions with the same symptoms and being admitted and diagnosed with serious mental disorders, leading to deinstitutionalisation.

The Sick Role and Illness Behavior

Mechanic and Volkart (1961) introduced the term illness behavior to describe how individuals perceive, evaluate, and respond to symptoms of physical dysfunction. Meanwhile, Talcott Parsons (1951) introduced the concept of the sick role as a temporary form of deviant behavior that is medically sanctioned.

According to Parsons, a sick person experiences conflicting desires to recover from the illness and to enjoy the secondary gains of attention and exemption from normal duties. The sick role is characterized by several rules, including the exemption of the sick person from their normal social roles, which is legitimized by society through the physician. The severity of the illness determines the strength of the exemption.

Additionally, sick persons are not held responsible for their illnesses, as they are beyond personal control. However, they have a duty to try to get well, as sickness is considered undesirable by society. Seeking competent technical help and cooperating with caregivers are also expected of sick persons.

In summary, the sick role and illness behavior are important concepts in understanding how individuals respond to physical dysfunction and how society legitimizes and responds to illness.

Gestalt Psychology and the Laws of Perceptual Organization

Gestalt psychology emerged as a response to structuralism, which aimed to break down thoughts into their basic components. Instead, Gestalt psychologists recognized that individual items must be examined together, as they interact and add complexity to the overall picture. Max Wertheimer, Kurt Koffka, and Wolfgang Köhler are important names associated with Gestalt psychology. Wertheimer discovered the phi phenomenon, which explains how rapid sequences of perceptual events create the illusion of motion. The Gestalt laws of perceptual organization explain how we tend to organize parts into wholes. These laws include symmetry and order, similarity, proximity, continuity, closure, and common fate. These laws help us understand how the mind groups similar elements into collective entities of totalities, and how spatial or temporal grouping of elements may induce the mind to perceive a collective of totality. Additionally, the laws explain how points that are connected by straight of curving lines are seen in a way that follows the smoothest path, and how things are grouped together if they seem to complete a picture. Finally, elements with the same moving direction are perceived as a collective of unit.

Stigma refers to a characteristic of behavior that is deemed shameful by society and causes an individual to be viewed as different from others.

Stigma is a term used to describe the negative attitudes and beliefs that people hold towards individuals who are different from them. There are several types of stigma, including discredited and discreditable stigma, felt stigma, enacted stigma, and courtesy stigma. Discredited stigma refers to visible stigmas such as race, gender, of physical disability, while discreditable stigma refers to concealable stigmas such as mental illness of HIV infection. Felt stigma is the shame and fear of discrimination that prevents people from seeking help, while enacted stigma is the experience of unfair treatment by others. Finally, courtesy stigma refers to the stigma that attaches to those who are associated with a stigmatized person.

Understanding Social Loafing

Social loafing is a common phenomenon that occurs when people work in groups. It refers to the tendency of individuals to exert less effort when working in a group than when working alone. This can be attributed to the diffusion of responsibility, where individuals feel less accountable for their actions when working in a group. As a result, they may not put in as much effort as they would if they were working alone. Social loafing can have negative consequences for group performance, as it can lead to a lack of motivation and a decrease in productivity. Therefore, it is important to understand the causes of social loafing and take steps to prevent it from occurring in group settings.

Memory: Encoding, Storage, Retrieval, and Failure

Memory is a complex process that involves encoding, storage, and retrieval of information. Encoding refers to how information is placed into memory, and it can be improved by organizing data using techniques such as chunking and mnemonics. Storage refers to keeping information in memory, which can be short-term of long-term. Retrieval refers to getting information back from memory when needed, and it can be affected by primacy and recency effects.

However, memory is not infallible, and there are seven ways in which it tends to fail. Transience refers to the decreasing accessibility of memory over time, while absent-mindedness is characterized by lapses of attention and forgetting to do things. Blocking is the temporary inaccessibility of stored information, while suggestibility involves the incorporation of misinformation into memory due to leading questions of deception.

Bias refers to retrospective distortions produced by current knowledge and beliefs, while persistence involves unwanted recollections that people cannot forget, such as the intrusive memories of post-traumatic stress disorder. Finally, misattribution refers to the attribution of memories to incorrect sources of believing that one has seen of heard something that they have not, such as in the case of deja vu of cryptomnesia.

Overall, memory is a complex and active process that can be affected by various factors, leading to failures in encoding, storage, retrieval, and attribution.

Selective attention involves filtering external stimuli and assigning meaning to things that should get our attention. Three main models have been proposed: Broadbent’s Filter model, Treisman’s Attenuation Theory, and Deutsch and Deutsch’s Late stage model. Broadbent’s model is an early selection model that filters input based on physical characteristics, while Treisman’s model is an intermediate selection model that uses a leaky filter to weaken some stimuli but allow them through. Deutsch and Deutsch’s model is a late selection model that analyzes input for meaning before filtering occurs. Treisman’s model includes a dictionary unit that emphasizes certain words have lower thresholds for getting our attention, such as our own name.

Thorndike’s Law of Effect

Thorndike’s law of effect is a principle that explains how the likelihood of an action occurring is influenced by the effect it has on the environment.

In simpler terms, this law suggests that actions that result in pleasurable outcomes are more likely to be repeated, while actions that lead to discomfort of negative consequences are less likely to be repeated.

This law has significant implications for behavior and learning. It suggests that positive reinforcement is a powerful tool for shaping behavior, as it increases the likelihood of a behavior being repeated. On the other hand, punishment of negative consequences may not be as effective in changing behavior, as they may only serve to decrease the likelihood of a behavior being repeated, rather than promoting a desired behavior.

Overall, Thorndike’s law of effect highlights the importance of understanding the consequences of our actions and how they shape our behavior. By focusing on positive reinforcement and creating environments that promote desirable behaviors, we can increase the likelihood of success and positive outcomes.

Social Capital: An Explanation for Inequalities in Morbidity and Mortality

The concept of social capital may provide insight into the observed disparities in morbidity and mortality based on occupational social class and material standard of living (McKenzie 2002). Social capital is considered the binding force of society, and it is believed that groups lacking in social capital may be at higher risk for mental illness.

Social capital is defined as the features of social life – networks, norms, and trust – that enable participants to act together more effectively to pursue shared objectives (Putnam, 1996). It is a characteristic of groups rather than individuals and can be divided into structural and cognitive components. Structural social capital includes roles, rules, behaviors, networks, and institutions that bond individuals in groups, bridge divides between societal groups, of vertically integrate groups with different levels of power and influence in a society, leading to social inclusion. Cognitive social capital refers to the values, attitudes, and beliefs that produce cooperative behavior (Colletta & Cullen, 2000).

In summary, social capital may offer an explanation for the observed inequalities in morbidity and mortality by occupational social class and material standard of living. It is a property of groups and can be broken down into structural and cognitive components.

Memory Forms

Memory is the ability to store, retain, and retrieve information. There are different forms of memory, including sensory memory, short-term/working memory, and long-term memory.

Sensory memory is the capacity for briefly retaining the large amounts of information that people encounter daily. It includes echoic memory (gathered through auditory stimuli), iconic memory (gathered through sight), and haptic memory (acquired through touch).

Short-term memory is the ability to keep a small amount of information available for a short period of time. Atkinson and Shiffrin’s multistore model (1968) suggests the existence of a short-term storehouse with limited capacity. Baddeley and Hitch (1974) further developed the concept of short-term memory, which eventually became known as Baddeley’s multi-storehouse model (2000). This model includes the central executive, visuospatial sketchpad, phonological buffer/loop, and episodic buffer.

Long-term memory includes declarative (of explicit) memories, which can be consciously retrieved, and nondeclarative (of implicit) memories, which cannot. Declarative memory includes episodic memory (stores personal experiences) and semantic memory (stores information about facts and concepts). Non-declarative memory includes procedural memory (recalls motor and executive skills), associative memory (storage and retrieval of information through association with other information), and non-associative memory (refers to newly learned behavior through repeated exposure to an isolated stimulus).

Overall, memory is a complex and essential cognitive function that plays a crucial role in learning, reasoning, and understanding.

In the exams, it is important to be familiar with the individuals associated with certain psychiatric terms. For example, Kraepelin is associated with dementia praecox and manic depression, while Bleuler is associated with schizophrenia.

While Kraepelin is often credited with coining the term dementia praecox, some sources suggest that it was first used in its Latin form by Arnold Pick in 1891. The original term demence precoce was first used by Morel in 1852. Despite this, the College appears to favor the Kraepelin attribution.

The WAIS includes working memory as a component, but it is not considered a fundamental skill.

Thurstone’s Theory of Intelligence

Louis Leon Thurstone believed that intelligence could not be reduced to a single factor. Instead, he proposed that intelligence is composed of seven distinct abilities, which he called the primary abilities. These abilities include word fluency, verbal comprehension, spatial visualization, number facility, associative memory, reasoning, and perceptual speed. According to Thurstone, each of these abilities is independent of the others and contributes to an individual’s overall intelligence. This theory challenged the prevailing view of intelligence at the time, which held that intelligence could be measured by a single factor known as the g factor. Thurstone’s theory has had a lasting impact on the field of psychology and has influenced the development of modern intelligence tests.

Double Agentry in Psychiatry

Double agentry is a term used to describe a situation where a psychiatrist’s conflict of interest interferes with their ability to act in the best interests of their patient. Psychiatrists often have to balance the interests of multiple parties, such as the patient, family, society, and hospital commissioners, which is known as multiagency.

The Tarasoff case is a prime example of double agentry in psychiatry. Two therapists failed to warn a woman that their patient had expressed an intention to kill her. They chose not to do so to respect the patient’s confidentiality, but failed to recognize their duty of care to both the patient and the potential victim. Unfortunately, the woman was eventually murdered by the patient.

This case, which occurred in California, led to a change in the law that now requires therapists to have a legal duty to both their patients and potential victims. It highlights the importance of psychiatrists being aware of their responsibilities to all parties involved and ensuring that they act in the best interests of their patients while also fulfilling their duty of care to others.

Operant Conditioning: Reinforcement, Punishment, and More

Operant conditioning, also known as instrumental learning, is a theory of learning developed by B.F. Skinner. It suggests that people learn by interacting with their environment. Reinforcement and punishment are key concepts in operant conditioning. A reinforcer is a stimulus of event that increases the likelihood of a behavior being repeated. Reinforcement can be positive of negative. Positive reinforcement occurs when a behavior is strengthened by adding a rewarding stimulus, while negative reinforcement occurs when a behavior is strengthened by removing an unpleasant stimulus. A punisher is a stimulus that decreases the likelihood of a behavior being repeated. Positive punishment occurs when a behavior is reduced in frequency by adding an unpleasant stimulus, while negative punishment occurs when a behavior is reduced in frequency by removing a pleasant stimulus.

Primary reinforcers are instinctual desires such as food, water, social approval, and sex. Secondary reinforcers, also known as conditioned reinforcers, are not innately appreciated and people have to learn to like them through classical conditioning of other methods. Secondary reinforcers include things such as money. Different patterns of reinforcement have different influences on the response. There are five main reinforcement schedules: fixed interval, variable interval, fixed ratio, variable ratio, and random. Variable ratio schedules are most resistant to extinction.

Shaping and chaining are techniques used when an exact behavior cannot be performed and so cannot be rewarded. Shaping involves rewarding successive, increasingly accurate approximations to the behavior, while chaining involves breaking a complex task into smaller, more manageable sections. Escape conditioning refers to a situation whereby an aversive situation is removed after a response. It is a form of negative reinforcement. Habituation refers to the phenomenon whereby there is a decrease in response to a stimulus over time. Covert sensitization is a technique used whereby someone learns to use mental imagery to associate a behavior with a negative consequence.

The working memory is overseen by the central executive, which manages all its functions. Although the exact location of the central executive is not fully comprehended, it is believed to involve various regions of the brain.

Memory Forms

Memory is the ability to store, retain, and retrieve information. There are different forms of memory, including sensory memory, short-term/working memory, and long-term memory.

Sensory memory is the capacity for briefly retaining the large amounts of information that people encounter daily. It includes echoic memory (gathered through auditory stimuli), iconic memory (gathered through sight), and haptic memory (acquired through touch).

Short-term memory is the ability to keep a small amount of information available for a short period of time. Atkinson and Shiffrin’s multistore model (1968) suggests the existence of a short-term storehouse with limited capacity. Baddeley and Hitch (1974) further developed the concept of short-term memory, which eventually became known as Baddeley’s multi-storehouse model (2000). This model includes the central executive, visuospatial sketchpad, phonological buffer/loop, and episodic buffer.

Long-term memory includes declarative (of explicit) memories, which can be consciously retrieved, and nondeclarative (of implicit) memories, which cannot. Declarative memory includes episodic memory (stores personal experiences) and semantic memory (stores information about facts and concepts). Non-declarative memory includes procedural memory (recalls motor and executive skills), associative memory (storage and retrieval of information through association with other information), and non-associative memory (refers to newly learned behavior through repeated exposure to an isolated stimulus).

Overall, memory is a complex and essential cognitive function that plays a crucial role in learning, reasoning, and understanding.

Theories of aggression can be categorized into three main perspectives: psychodynamic, sociological/drive, and cognitive and learning. Psychodynamic theory, proposed by Freud, suggests that aggression arises from a primary instinct called thanatos, which aims for destruction and death. Sociobiological/drive theory, proposed by Lorenz, suggests that aggression is instinctual and necessary for survival, and that stronger genes are selected through aggression. Cognitive and learning theory, proposed by Berkowitz, Rotter, Bandura, and Anderson, suggests that aggression can be learned through observational learning and is influenced by environmental factors. Bandura’s work introduced the concept of reciprocal determinism, which suggests that behavior is influenced by both the environment and the individual’s behavior. Rotter’s social learning theory emphasizes the interaction between the individual and their environment, while Anderson and Bushman’s general aggression model considers the role of social, cognitive, developmental, and biological factors on aggression.

Erving Goffman was a prominent sociologist who made significant contributions to the field. He is well-known for his works such as The Presentation of Self in Everyday Life, Asylums, and Stigma. In fact, he is credited with introducing the term stigma into the sociological lexicon. Goffman’s ideas and theories have had a lasting impact on the study of sociology and continue to be studied and applied today.

Flashbulb Memory

Flashbulb memories are vivid and detailed recollections of the circumstances surrounding a significant event. These memories are typically episodic, meaning they are focused on the specific details of the event rather than just the facts. One example of a flashbulb memory might be recalling where you were and what you were doing when you first heard about the death of Princess Diana in 1997. What sets flashbulb memories apart from other types of memories is the high level of emotional arousal that accompanies them. This emotional intensity helps to cement the memory in the mind, making it more vivid and long-lasting.

The Importance of Culture and its Impact on Individuals

Culture plays a vital role in society by providing consistency and organization to its patterns and components over generations. It helps to manage diversity and balance the forces of stability and conformity with those of change and innovation. By classifying phenomena into categories such as good and bad, right and wrong, healthy and sick, and desirable and undesirable, culture provides individuals with behavioral guidelines and an interpretation of life events.

When adults, such as migrants of refugees, fully adopt the culture of a host society and lose their own cultural identity, they are said to be assimilated. However, in acculturation, individuals take on some aspects of the host culture while retaining their own cultural identity.

Culture is learned through various means, including contact with family, friends, classmates, teachers, significant persons, and the media. This process is known as enculturation.

Accommodation refers to the reconciliation of differences, while sojourning involves staying as a temporary resident.

According to utilitarianism, the morally right action is one that results in the most happiness for the largest number of people. This ethical theory was first introduced by Jeremy Bentham in the early 1800s and later refined by John Stuart Mill. The ultimate goal is to maximize utility, which is the overall amount of pleasure of happiness in the world. In order to achieve this, the consequences of an action on all those affected must be considered. However, a utilitarian may have to acknowledge that sometimes the greatest happiness for the greatest number can only be achieved by violating certain rights, such as the right to not be punished if innocent.

Ethical theory and principles are important in medical ethics. There are three key ethical theories that have dominated medical ethics: utilitarianism, deontological, and virtue-based. Utilitarianism is based on the greatest good for the greatest number and is a consequentialist theory. Deontological ethics emphasize moral duties and rules, rather than consequences. Virtue ethics is based on the ethical characteristics of a person and is associated with the concept of a good, happy, flourishing life.

More recent frameworks have attempted to reconcile different theories and values. The ‘four principles’ of ‘principlism’ approach, developed in the United States, is based on four common, basic prima facie moral commitments: autonomy, beneficence, non-maleficence, and justice. Autonomy refers to a patient’s right to make their own decisions, beneficence refers to the expectation that a doctor will act in a way that will be helpful to the patient, non-maleficence refers to the fact that doctors should avoid harming their patients, and justice refers to the expectation that all people should be treated fairly and equally.

Sleep Disorders

The International Classification of Sleep Disorders (ISCD) categorizes sleep disorders into several main categories and subclasses. Dyssomnias are intrinsic sleep disorders that include narcolepsy, psychopsychologic insomnia, idiopathic hypersomnia, restless leg syndrome, periodic limb movement disorder, and obstructive sleep apnea. Extrinsic sleep disorders include inadequate sleep hygiene and alcohol-dependent sleep disorder. Circadian rhythm disorders consist of jet lag syndrome, shift work sleep disorder, irregular sleep-wake pattern, delayed sleep phase syndrome, and advanced sleep phase disorder. Parasomnias include arousal disorders such as sleepwalking and sleep terrors, sleep-wake transition disorders such as rhythmic movement disorder, sleep talking, and nocturnal leg cramps, and parasomnias associated with REM sleep such as nightmares and sleep paralysis. Sleep disorders associated with medical/psychiatric disorders and proposed sleep disorders are also included in the classification.

Narcolepsy is a disorder of unknown cause that is characterized by excessive sleepiness, cataplexy, and other REM sleep phenomena such as sleep paralysis and hypnagogic hallucinations. Periodic limb movement disorder is characterized by periodic episodes of repetitive and highly stereotyped limb movements that occur during sleep. Restless legs syndrome is a disorder characterized by disagreeable leg sensations that usually occur prior to sleep onset and that cause an almost irresistible urge to move the legs. Jet lag syndrome consists of varying degrees of difficulties in initiating or maintaining sleep, excessive sleepiness, decrements in subjective daytime alertness and performance, and somatic symptoms following rapid travel across multiple time zones. Shift work sleep disorder consists of symptoms of insomnia of excessive sleepiness that occur as transient phenomena in relation to work schedules. Non 24 hour sleep wake syndrome consists of a chronic steady pattern comprising one to two hour daily delays in sleep onset and wake times in an individual living in society. Sleepwalking consists of a series of complex behaviors that are initiated during slow-wave sleep and result in walking during sleep. Sleep terrors are characterized by a sudden arousal from slow wave sleep with a piercing scream of cry, accompanied by autonomic and behavioral manifestations of intense fear. Rhythmic movement disorder comprises a group of stereotyped, repetitive movements involving large muscles, usually of the head and neck. Sleep starts are sudden, brief contractions of the legs, sometimes also involving the arms and head, that occur at sleep onset. Nocturnal leg cramps are painful sensations of muscular tightness of tension, usually in the calf but occasionally in the foot, that occur during the sleep episode. Nightmares are frightening dreams that usually awaken the sleeper from REM sleep. Sleep paralysis is a common condition characterized by transient paralysis of skeletal muscles which occurs when awakening from sleep of less often while falling asleep.

Classical Conditioning: A Learning Theory by Ivan Pavlov

Classical conditioning is a learning theory developed by Ivan Pavlov. It suggests that events that occur together are associated and acquire a similar meaning. Unlike operant conditioning, which focuses on responses to behavior, classical conditioning looks at responses to stimuli. In classical conditioning, animals behave as if they have learned to associate a stimulus with a significant event. Pavlov demonstrated that innate responses, such as a dog salivating when it sees food, can be associated with a neutral stimulus, such as ringing a bell, so that ringing the bell can cause salivation even in the absence of food.

Important terms used in classical conditioning include stimulus generalization and discrimination, higher order conditioning, spontaneous recovery, and aversive conditioning. Extinction is the laboratory analogue of exposure therapy for anxiety disorders, while Counterconditioning involves pairing a feared conditioned stimulus with a positive outcome. Incubation occurs in fear responses, and reciprocal inhibition is a technique that aims to replace an undesired response with a desired one by counterconditioning. Some stimuli are more prone to conditioning than others, which is referred to as stimulus/biological preparedness.

Memory Forms

Memory is the ability to store, retain, and retrieve information. There are different forms of memory, including sensory memory, short-term/working memory, and long-term memory.

Long-term memory includes declarative (of explicit) memories, which can be consciously retrieved, and nondeclarative (of implicit) memories, which cannot. Declarative memory includes episodic memory (stores personal experiences) and semantic memory (stores information about facts and concepts). Non-declarative memory includes procedural memory (recalls motor and executive skills), associative memory (storage and retrieval of information through association with other information), and non-associative memory (refers to newly learned behavior through repeated exposure to an isolated stimulus).

Overall, memory is a complex and essential cognitive function that plays a crucial role in learning, reasoning, and understanding.

Deontological (duty-based) ethics prioritize the actions of individuals over the observable practical consequences of those actions.

The concept of the sick role pertains to an implicit agreement between an individual who falls ill and the community they belong to.

The Sick Role and Illness Behavior

Mechanic and Volkart (1961) introduced the term illness behavior to describe how individuals perceive, evaluate, and respond to symptoms of physical dysfunction. Meanwhile, Talcott Parsons (1951) introduced the concept of the sick role as a temporary form of deviant behavior that is medically sanctioned.

According to Parsons, a sick person experiences conflicting desires to recover from the illness and to enjoy the secondary gains of attention and exemption from normal duties. The sick role is characterized by several rules, including the exemption of the sick person from their normal social roles, which is legitimized by society through the physician. The severity of the illness determines the strength of the exemption.

Additionally, sick persons are not held responsible for their illnesses, as they are beyond personal control. However, they have a duty to try to get well, as sickness is considered undesirable by society. Seeking competent technical help and cooperating with caregivers are also expected of sick persons.

In summary, the sick role and illness behavior are important concepts in understanding how individuals respond to physical dysfunction and how society legitimizes and responds to illness.

Teleology, derived from the Greek words for goal and theory, is a moral philosophy that emphasizes the outcomes of actions as the initial consideration in evaluating ethical behavior. This category of theories is also known as consequentialism, as it focuses on the consequences of an action as the basis for determining its morality. Consequentialism evaluates the morality of an action based on the balance of its positive and negative outcomes. Utilitarianism of social consequentialism is the most prevalent form of consequentialism, although it is not the only one.

Ethical theory and principles are important in medical ethics. There are three key ethical theories that have dominated medical ethics: utilitarianism, deontological, and virtue-based.

Freud’s Structural Theory: Understanding the Three Areas of the Mind

According to Freud’s structural model, the human mind is divided into three distinct areas: the Id, the Ego, and the Superego. The Id is the part of the mind that contains instinctive drives and operates on the ‘pleasure principle’. It functions without a sense of time and is governed by ‘primary process thinking’. The Ego, on the other hand, attempts to modify the drives from the Id with external reality. It operates on the ‘reality principle’ and has conscious, preconscious, and unconscious aspects. It is also home to the defense mechanisms. Finally, the Superego acts as a critical agency, constantly observing a person’s behavior. Freud believed that it developed from the internalized values of a child’s main caregivers. The Superego contains the ‘ego ideal’, which represents ideal attitudes and behavior. It is often referred to as the conscience. Understanding these three areas of the mind is crucial to understanding Freud’s structural theory.

Bion, a psychoanalyst, was fascinated by group dynamics and believed that groups had a collective unconscious that functioned similarly to that of an individual. He argued that this unconsciousness protected the group from the pain of reality. Bion identified two types of groups: the ‘working group’ that functioned well and achieved its goals, and the ‘basic assumption group’ that acted out primitive fantasies and prevented progress. Bion then described different types of basic assumption groups, including ‘dependency,’ where the group turns to a leader to alleviate anxiety, ‘fight-flight,’ where the group perceives an enemy and either attacks of avoids them, and ‘pairing,’ where the group believes that the solution lies in the pairing of two members. These dynamics can be observed in various settings, such as when strangers come together for the first time of when doctors in different specialties criticize one another.

All the other choices are components of the WAIS (Wechsler Adult Intelligence Scale).

Thurstone’s theory has had a lasting impact on the field of psychology and has influenced the development of modern intelligence tests.

B.F. Skinner, a prominent figure in the field of psychology, is renowned for his contributions to the theory of reinforcement within the behaviourist perspective.

Neo-Freudians were therapists who developed their own theories while still retaining core Freudian components. Some important neo-Freudians include Alfred Adler, Carl Jung, Erik Erickson, Harry Stack Sullivan, Wilfred Bion, John Bowlby, Anna Freud, Otto Kernberg, Margaret Mahler, and Donald Winnicott. Each of these individuals contributed unique ideas to the field of psychology. For example, Carl Jung introduced the concept of the persona and differentiated between the personal and collective unconscious, while Erik Erickson is known for his stages of psychosocial development. Margaret Mahler developed theories on child development, including the three main phases of autistic, symbiotic, and separation-individuation. Donald Winnicott introduced the concept of the transitional object and the good enough mother. Overall, neo-Freudians expanded upon Freud’s ideas and helped to shape modern psychotherapy.

Diathesis-Stress Model

The Diathesis-Stress Model acknowledges that a person’s behavior is influenced by both their experiences and genetics. This model proposes that some individuals have a pre-existing vulnerability (diathesis) towards a particular illness, and that certain environmental stressors can trigger the onset of the illness. The model emphasizes the interplay between nature and nurture in shaping a person’s mental health.

If you are familiar with the ‘phonological Loop’ component of the working memory, you may be able to deduce the meaning of the ‘phonological similarity effect’. This effect describes the difficulty in remembering words that sound alike. Additionally, the ‘word-length effect’ and ‘articulatory suppression’ are two other phenomena that involve the working memory.

Memory Forms

Memory is the ability to store, retain, and retrieve information. There are different forms of memory, including sensory memory, short-term/working memory, and long-term memory.

Sensory memory is the capacity for briefly retaining the large amounts of information that people encounter daily. It includes echoic memory (gathered through auditory stimuli), iconic memory (gathered through sight), and haptic memory (acquired through touch).

Non-declarative memory includes procedural memory (recalls motor and executive skills), associative memory (storage and retrieval of information through association with other information), and non-associative memory (refers to newly learned behavior through repeated exposure to an isolated stimulus).

Overall, memory is a complex and essential cognitive function that plays a crucial role in learning, reasoning, and understanding.

The Significance of the Declaration of Helsinki in Biomedical Research Ethics

The Declaration of Helsinki, created by the World Medical Association in 1964, outlines the fundamental ethical principles that govern biomedical research involving human subjects. Over the years, it has undergone several revisions and continues to serve as a cornerstone of good medical practice. Its importance lies in its ability to provide a framework for ethical decision-making in research, ensuring that the rights, safety, and well-being of human subjects are protected. The Declaration of Helsinki is a crucial document that guides researchers, clinicians, and policymakers in their efforts to conduct ethical and responsible research.

The term ‘extinction’ has distinct connotations in classical conditioning and operant conditioning. In operant conditioning, it denotes the waning of an operant response due to the absence of reinforcement. In classical conditioning, it signifies a decrease in a conditioned response (such as salivation) when a conditioned stimulus (such as a bell ringing) is repeatedly presented without the unconditioned stimulus (such as food) that it was previously associated with.

Operant Conditioning: Reinforcement, Punishment, and More

Operant conditioning, also known as instrumental learning, is a theory of learning developed by B.F. Skinner. It suggests that people learn by interacting with their environment.

Understanding Incentive Salience and its Role in Addiction and Grief

Incentive salience is a process that drives the brain to desire certain things, such as drugs, and is mediated by mesolimbic dopamine systems. This process is separate from the experience of pleasure, and a person can want something they don’t necessarily like. Desire is amplified by brain states that heighten dopamine reactivity, such as stress, emotional excitement, relevant appetites, of intoxication. This state-dependent amplification of incentive salience is one reason why many addicts find it difficult to stop at just one hit.

Interestingly, grief has been hypothesized to be underpinned by a very similar process as drug addiction, referred to as the ‘incentive salience theory of grief’. Understanding the distinction between liking and wanting can help us better understand addiction and grief, and how the brain processes these experiences.

Temperament is the innate aspect of an individual’s personality that is believed to be influenced by genetics, while character is shaped by learned experiences. Thomas and Chess developed a classification system that assesses children’s behavior based on nine traits, including activity level, adaptability, and emotional response. They found that 65% of children fall into one of three temperament types: easy, difficult, of slow to warm up. Thomas and Chess also introduced the concept of goodness of fit, which refers to the compatibility between a child’s temperament and their environment. When there is a good fit, children are more likely to reach their potential. For example, teachers can provide active learning experiences for children with high activity levels instead of seat work.

The term phatic communication is used to describe casual conversation. The ‘cocktail party effect’ is the ability to concentrate on one person’s voice in any setting, such as a classroom, sports game, of coffee shop, even if there is a lot of background noise.

The Cocktail Party Effect: Selective Attention in Noisy Environments

The cocktail party effect is a phenomenon that allows individuals to selectively focus on a single conversation in a noisy environment, while ignoring other competing conversations. This feature of selective attention is particularly useful in social situations, such as parties, where multiple conversations are taking place simultaneously. For instance, if you are conversing with a friend at a noisy party, you can effectively tune out the surrounding noise and concentrate on your friend’s conversation. This ability to filter out irrelevant information and focus on relevant information is a crucial aspect of human cognition. It enables us to navigate complex social environments and engage in meaningful interactions with others.

The Goldstein-Scheerer Object Sorting Test for Assessing Abstract Thinking

The Goldstein-Scheerer Object Sorting test is a diagnostic tool used to evaluate abstract thinking and the ability to form concepts. This test requires patients to sort objects based on their colour of material, as well as copy block patterns using coloured cubes. The test is primarily used to diagnose neurological problems. By assessing a patient’s ability to sort objects and form concepts, doctors can gain insight into their cognitive abilities and identify any potential neurological issues. The Goldstein-Scheerer Object Sorting test is an effective tool for evaluating abstract thinking and cognitive function.

This test involves sorting objects based on their colour of material and copying block patterns using coloured cubes. The purpose of this test is to assess the patient’s cognitive abilities and determine their level of abstract thinking. By analyzing the patient’s performance on this test, healthcare professionals can gain insight into their cognitive functioning and develop appropriate treatment plans. The Goldstein-Scheerer Object Sort Test is a valuable tool for assessing cognitive abilities and can be used in a variety of healthcare settings.

Trait Theory: Understanding Personality Traits

Trait theory is a psychological approach that seeks to understand personality by identifying and categorizing specific traits. The theory was first introduced by Gordon Allport, who classified personality traits into three levels.

At the highest level, we have cardinal traits. These are traits that are so pervasive that they dominate a person’s behavior and activities. Only a few people possess cardinal traits, but for those who do, these traits are the ruling force of their personality. Cardinal traits are usually evident to most people who know the individual.

The second level of traits is central traits. These are easily detected characteristics within a person, traits that all people have a certain number of, usually around five to ten on average. Central traits are the building blocks of personality and help to define a person’s overall character.

Finally, we have secondary traits. These are less evident and only manifest in select circumstances. They are not as important as central of cardinal traits, but they still play a role in shaping a person’s behavior and personality.

Overall, trait theory provides a useful framework for understanding personality and how it develops over time. By identifying and categorizing specific traits, psychologists can gain insights into why people behave the way they do and how they can change their behavior to achieve their goals.

Cognitive Dissonance is a term used to describe the uncomfortable feeling that arises when there is a conflict between an individual’s attitudes, beliefs, of behaviors. This feeling can lead to a change in behavior of beliefs. The theory of cognitive dissonance suggests that people have an inner drive to maintain cognitive consistency and avoid dissonance. This drive can result in irrational of maladaptive behaviors. Dissonance can be reduced by changing attitudes, behaviors, of beliefs, acquiring new information, of reducing the importance of the cognitions. Overall, cognitive dissonance plays a significant role in shaping human behavior and decision-making.

She has maintained her home culture and not assimilated into the dominant culture, which is known as separation.

Multiculturalism is the coexistence of various cultural of ethnic groups within a shared social and political framework. Acculturation is the process of cultural and psychological change that occurs when different cultural groups come into contact with each other. Canadian psychologist John Berry identified four paths to acculturation: assimilation, integration, separation, and marginalization. Assimilation involves giving up one’s home culture and adopting the dominant culture, while integration involves maintaining one’s home culture while also embracing the dominant culture. Separation involves maintaining one’s home culture while being isolated from the dominant culture, and marginalization involves giving up one’s home culture and failing to related properly to the dominant culture. There is a cultural debate regarding assimilation and multiculturalism, with two forms of assimilation recognized: total assimilation, which involves the obliteration of the non-dominant culture, and melting pot assimilation, which refers to a less extreme version where a new form of the dominant culture emerges. Laissez-faire multiculturalism refers to multiculturalism that occurs without planning, such as the existence of Chinatowns in most cities.

Goffman coined the term ‘total institution’ in relation to asylums, which were responsible for fulfilling all the patients’ requirements, thereby hindering their rehabilitation.

D.W. Winnicott – Good enough mother, transitional object: Winnicott believed that a good enough mother is one who provides a secure and nurturing environment for her child, allowing them to develop a sense of self and independence. He also introduced the concept of the transitional object, such as a teddy bear of blanket, which helps a child transition from the mother’s care to the outside world.

Carl Jung – Collective unconscious, archetype, anima, animus: Jung believed in the existence of a collective unconscious, a shared pool of knowledge and experience that all humans possess. He also introduced the concept of archetypes, universal symbols and patterns that are present in the collective unconscious. The anima and animus are archetypes representing the feminine and masculine aspects of the psyche.

Melanie Klein – Paranoid-schizoid position, depressive position, splitting: Klein introduced the concept of the paranoid-schizoid position, a stage of development in which a child experiences intense anxiety and fear of persecution. She also introduced the depressive position, a stage in which the child learns to integrate positive and negative feelings towards others. Splitting is the defense mechanism in which a person sees things as either all good of all bad.

Sigmund Freud – Free association, transference, ego, super-ego, id, eros, thanatos, defense mechanisms, oedipus Complex, the unconscious: Freud is known for his theories on the unconscious mind, including the id, ego, and super-ego. He also introduced the concepts of eros (the life instinct) and thanatos (the death instinct), as well as defense mechanisms such as repression and denial. The Oedipus complex is a theory about a child’s sexual desire for their opposite-sex parent.

Wilfred Bion – Basic assumption group: Bion introduced the concept of the basic assumption group, a group that forms around a shared fantasy of assumption. He believed that these groups can be helpful of harmful, depending on the assumptions they are based on.

Karen Horney – Womb envy: Horney believed that men experience womb envy, a feeling of inferiority and jealousy towards women due to their inability to bear children. She also introduced the concept of neurotic needs, such as the need for affection and the need for power.

Erving Goffman – Total institution: Goffman introduced the concept of the total institution, a place where people are completely cut off from the outside world and subjected to strict rules and regulations. Examples include prisons and mental hospitals.

Siegfried Foulkes – Foundation matrix: Foulkes introduced the concept of the foundation matrix, a group’s shared history and experiences that shape their current dynamics and interactions.

Freud’s Structural Theory: Understanding the Three Areas of the Mind

According to Freud’s structural model, the human mind is divided into three distinct areas: the Id, the Ego, and the Superego. The Id is the part of the mind that contains instinctive drives and operates on the ‘pleasure principle’. It functions without a sense of time and is governed by ‘primary process thinking’. The Ego, on the other hand, attempts to modify the drives from the Id with external reality. It operates on the ‘reality principle’ and has conscious, preconscious, and unconscious aspects. It is also home to the defense mechanisms. Finally, the Superego acts as a critical agency, constantly observing a person’s behavior. Freud believed that it developed from the internalized values of a child’s main caregivers. The Superego contains the ‘ego ideal’, which represents ideal attitudes and behavior. It is often referred to as the conscience. Understanding these three areas of the mind is crucial to understanding Freud’s structural theory.

Stigma Models

Stigma refers to any attribute, trait, of disorder that marks an individual as being unacceptably different from the normal people with whom they routinely interact, and that elicits some form of community sanction. The most popular model of stigma comes from the work of Link and Phelan, which has four aspects to it.

The first aspect is labelling, which refers to personal characteristics that mark individuals as different. These characteristics can be physical, mental, of social in nature and can include things like race, gender, sexual orientation, of mental illness.

The second aspect is stereotyping, which involves linking labelled characteristics to undesirable characteristics. For example, people with mental illness may be stereotyped as violent of unpredictable, even though the vast majority of them are not.

The third aspect is separating, which involves separating the labelled group and normal people by viewing them as very different. This can lead to social isolation and exclusion, which can further exacerbate the negative effects of stigma.

The fourth and final aspect is status loss and discrimination, which refers to the devaluing, rejecting, and excluding of the labelled group. This can take many forms, including employment discrimination, housing discrimination, and social exclusion.

Overall, the model of stigma developed by Link and Phelan provides a useful framework for understanding the complex and multifaceted nature of stigma and its effects on individuals and society as a whole.

The symptoms exhibited by the patient are consistent with Koro, a culture-specific disorder observed primarily in males (and occasionally in females) in China and Thailand.

Operant Conditioning: Reinforcement, Punishment, and More

Operant conditioning, also known as instrumental learning, is a theory of learning developed by B.F. Skinner. It suggests that people learn by interacting with their environment. Reinforcement and punishment are key concepts in operant conditioning. A reinforcer is a stimulus of event that increases the likelihood of a behavior being repeated. Reinforcement can be positive of negative. Positive reinforcement occurs when a behavior is strengthened by adding a rewarding stimulus, while negative reinforcement occurs when a behavior is strengthened by removing an unpleasant stimulus. A punisher is a stimulus that decreases the likelihood of a behavior being repeated. Positive punishment occurs when a behavior is reduced in frequency by adding an unpleasant stimulus, while negative punishment occurs when a behavior is reduced in frequency by removing a pleasant stimulus.

Primary reinforcers are instinctual desires such as food, water, social approval, and sex. Secondary reinforcers, also known as conditioned reinforcers, are not innately appreciated and people have to learn to like them through classical conditioning of other methods. Secondary reinforcers include things such as money. Different patterns of reinforcement have different influences on the response. There are five main reinforcement schedules: fixed interval, variable interval, fixed ratio, variable ratio, and random. Variable ratio schedules are most resistant to extinction.

Shaping and chaining are techniques used when an exact behavior cannot be performed and so cannot be rewarded. Shaping involves rewarding successive, increasingly accurate approximations to the behavior, while chaining involves breaking a complex task into smaller, more manageable sections. Escape conditioning refers to a situation whereby an aversive situation is removed after a response. It is a form of negative reinforcement. Habituation refers to the phenomenon whereby there is a decrease in response to a stimulus over time. Covert sensitization is a technique used whereby someone learns to use mental imagery to associate a behavior with a negative consequence.

Ethical theory and principles are important in medical ethics. There are three key ethical theories that have dominated medical ethics: utilitarianism, deontological, and virtue-based. Utilitarianism is based on the greatest good for the greatest number and is a consequentialist theory. Deontological ethics emphasize moral duties and rules, rather than consequences. Virtue ethics is based on the ethical characteristics of a person and is associated with the concept of a good, happy, flourishing life.

More recent frameworks have attempted to reconcile different theories and values. The ‘four principles’ of ‘principlism’ approach, developed in the United States, is based on four common, basic prima facie moral commitments: autonomy, beneficence, non-maleficence, and justice. Autonomy refers to a patient’s right to make their own decisions, beneficence refers to the expectation that a doctor will act in a way that will be helpful to the patient, non-maleficence refers to the fact that doctors should avoid harming their patients, and justice refers to the expectation that all people should be treated fairly and equally.

Controversial studies in psychiatry have been a popular topic in exams. One such study was the Willowbrook School Study, where healthy children with learning difficulties were inoculated with hepatitis to assess the potential of gamma globulin to treat the disorder. Beecher’s study listed over 20 cases of mainstream research where subjects were experimented on without being fully informed of the risks. The Tuskegee syphilis experiment followed impoverished African-American sharecroppers with syphilis, and a significant proportion did not receive available treatment. Stanford’s prison experiment created a simulated prison environment where participants became their assigned roles, with guards becoming harsh and cruel to prisoners. The Tearooms Study involved Humphreys pretending to be a ‘watch queen’ to study men who have sex in public toilets, raising the issue of informed consent. Milgram’s Study investigated authority and obedience, where participants administered fake shocks to a confederate, with 30 participants continuing to administer shocks until 450 volts was reached. The Rosenhan experiment involved pseudopatients presenting themselves at institutions with the same symptoms and being admitted and diagnosed with serious mental disorders, leading to deinstitutionalisation.

Social Capital: An Explanation for Inequalities in Morbidity and Mortality

The concept of social capital may provide insight into the observed disparities in morbidity and mortality based on occupational social class and material standard of living (McKenzie 2002). Social capital is considered the binding force of society, and it is believed that groups lacking in social capital may be at higher risk for mental illness.

Social capital is defined as the features of social life – networks, norms, and trust – that enable participants to act together more effectively to pursue shared objectives (Putnam, 1996). It is a characteristic of groups rather than individuals and can be divided into structural and cognitive components. Structural social capital includes roles, rules, behaviors, networks, and institutions that bond individuals in groups, bridge divides between societal groups, of vertically integrate groups with different levels of power and influence in a society, leading to social inclusion. Cognitive social capital refers to the values, attitudes, and beliefs that produce cooperative behavior (Colletta & Cullen, 2000).

In summary, social capital may offer an explanation for the observed inequalities in morbidity and mortality by occupational social class and material standard of living. It is a property of groups and can be broken down into structural and cognitive components.

Escape conditioning involves ending an unpleasant stimulus by performing a certain behavior, while avoidance conditioning involves avoiding the presentation of an unpleasant stimulus by performing a certain behavior.

The head injury resulted in anterograde amnesia, which is characterized by memory loss for events that occurred after the injury.

Understanding Amnesia: Types and Causes

Amnesia is a memory deficit that can be categorized into two types: anterograde and retrograde. Anterograde amnesia refers to the inability to create new memories, while retrograde amnesia refers to the loss of memory for information acquired before the onset of amnesia. The damage to the hippocampus and medial temporal lobe is often associated with amnesia. Source amnesia is the inability to remember where of how previously learned information was acquired. Psychogenic amnesia is characterized by sudden retrograde episodic memory loss, while semantic amnesia affects semantic memory and language use. Transient global amnesia is a condition that affects those over 50 and spontaneously resolves within 24 hours, with no clear cause identified. Understanding the types and causes of amnesia can help in its diagnosis and treatment.

Neo-Freudians were therapists who developed their own theories while still retaining core Freudian components. Some important neo-Freudians include Alfred Adler, Carl Jung, Erik Erickson, Harry Stack Sullivan, Wilfred Bion, John Bowlby, Anna Freud, Otto Kernberg, Margaret Mahler, and Donald Winnicott. Each of these individuals contributed unique ideas to the field of psychology. For example, Carl Jung introduced the concept of the persona and differentiated between the personal and collective unconscious, while Erik Erickson is known for his stages of psychosocial development. Margaret Mahler developed theories on child development, including the three main phases of autistic, symbiotic, and separation-individuation. Donald Winnicott introduced the concept of the transitional object and the good enough mother. Overall, neo-Freudians expanded upon Freud’s ideas and helped to shape modern psychotherapy.

Gestalt Psychology and the Laws of Perceptual Organization

Gestalt psychology emerged as a response to structuralism, which aimed to break down thoughts into their basic components. Instead, Gestalt psychologists recognized that individual items must be examined together, as they interact and add complexity to the overall picture. Max Wertheimer, Kurt Koffka, and Wolfgang Köhler are important names associated with Gestalt psychology. Wertheimer discovered the phi phenomenon, which explains how rapid sequences of perceptual events create the illusion of motion. The Gestalt laws of perceptual organization explain how we tend to organize parts into wholes. These laws include symmetry and order, similarity, proximity, continuity, closure, and common fate. These laws help us understand how the mind groups similar elements into collective entities of totalities, and how spatial or temporal grouping of elements may induce the mind to perceive a collective of totality. Additionally, the laws explain how points that are connected by straight of curving lines are seen in a way that follows the smoothest path, and how things are grouped together if they seem to complete a picture. Finally, elements with the same moving direction are perceived as a collective of unit.

Maslow proposed a hierarchy of needs that must be met for an individual to achieve self-actualization, starting with basic physiological needs such as hunger and thirst. Allport and Odbert focused on studying individuals and their unique traits, rather than groups. Kelly developed the phenomenological approach and personal construct theory. Rogers believed in the inherent self-knowledge and rationality of all humans and is known for his work in client-centered therapy.

The Willowbrook School Study was conducted in a state-supported institution for children with learning difficulties in New York during the 1960s. The study involved inoculating healthy children with hepatitis and administering gamma globulin to assess its potential to treat the disorder.

The Tuskegee syphilis experiment was a controversial follow-up study of people with syphilis. Many participants were not informed of their illness and did not receive available treatment, even though it became available halfway through the study. The Belmont report introduced changes to US law on research ethics as a result of this study.

The Stanford prison experiment involved creating a simulated prison environment at Stanford University. Participants were assigned as either a prison of a guard and were given no guidelines for how to behave. Within two days, the participants began to act out their assigned roles, with guards becoming harsh and sometimes cruel to the prisoners. The study was terminated after only six days due to extreme emotional reactions from some of the prisoners.

The Tearooms Study involved Humphreys hanging around public toilets where men meet to have sex in order to study the population and learn more about the types of men that did it. The method was controversial as he never disclosed his motives when he interviewed the men and instead pretended to be a ‘watch queen’, raising issues of informed consent in research.

Milgram’s Study investigated authority and obedience. Participants were assigned the role of teacher and administered fake shocks to a confederate playing the learner. Despite expressing concern, 30% of participants continued to administer shocks until 450 volts was reached. The study raised concerns for the wellbeing of participants, but Milgram decided not to terminate it as prior participants seemed to recover relatively well.

Beecher’s Study

Beecher’s study revealed more than 20 instances where individuals were subjected to experimentation without being fully informed of their participation in research and the potential risks involved. One of the cases cited was the Willowbrook State School study, where children with mental disabilities were intentionally infected with hepatitis under the guise of a vaccination program.

Classical Conditioning: A Learning Theory by Ivan Pavlov

Classical conditioning is a learning theory developed by Ivan Pavlov. It suggests that events that occur together are associated and acquire a similar meaning. Unlike operant conditioning, which focuses on responses to behavior, classical conditioning looks at responses to stimuli. In classical conditioning, animals behave as if they have learned to associate a stimulus with a significant event. Pavlov demonstrated that innate responses, such as a dog salivating when it sees food, can be associated with a neutral stimulus, such as ringing a bell, so that ringing the bell can cause salivation even in the absence of food.

Important terms used in classical conditioning include stimulus generalization and discrimination, higher order conditioning, spontaneous recovery, and aversive conditioning. Extinction is the laboratory analogue of exposure therapy for anxiety disorders, while Counterconditioning involves pairing a feared conditioned stimulus with a positive outcome. Incubation occurs in fear responses, and reciprocal inhibition is a technique that aims to replace an undesired response with a desired one by counterconditioning. Some stimuli are more prone to conditioning than others, which is referred to as stimulus/biological preparedness.

Understanding Behavioural Activation Therapy for Depression

Behavioural activation therapy is a formal treatment for depression that emphasizes activity scheduling to encourage patients to approach activities they are avoiding. Unlike traditional cognitive therapy, it involves less cognitive therapy and is easier to train staff in its use. The therapy was introduced by Martell in 2001 and has two primary focuses: the use of avoided activities as a guide for activity scheduling and functional analysis of cognitive processes that involve avoidance.

Behavioural activation theory suggests that when people become depressed, many of their activities function as avoidance and escape from aversive thoughts, feelings, of external situations. As a result, someone with depression engages less frequently in pleasant of satisfying activities and obtains less positive reinforcement than someone without depression. To address this, the patient is encouraged to identify activities and problems that they avoid and to establish valued directions to be followed. These are set out on planned timetables (activity schedules).

In behavioural activation therapy, therapists do not engage in the content of the patient’s thinking. Instead, they use functional analysis to focus on the context and process of the individual’s response. The most common cognitive responses are rumination, fusion, and self-attack. A typical session has a structured agenda to review homework and progress towards goals, discuss feedback on the previous session, and focus on one of two specific issues. The number of sessions required to treat depression is typically between 12 and 24.

The question pertains to the patient’s comprehension of the microwave’s purpose (semantic memory), rather than their ability to operate it (procedural memory).

Memory Forms

Memory is the ability to store, retain, and retrieve information. There are different forms of memory, including sensory memory, short-term/working memory, and long-term memory.

Sensory memory is the capacity for briefly retaining the large amounts of information that people encounter daily. It includes echoic memory (gathered through auditory stimuli), iconic memory (gathered through sight), and haptic memory (acquired through touch).

Short-term memory is the ability to keep a small amount of information available for a short period of time. Atkinson and Shiffrin’s multistore model (1968) suggests the existence of a short-term storehouse with limited capacity. Baddeley and Hitch (1974) further developed the concept of short-term memory, which eventually became known as Baddeley’s multi-storehouse model (2000). This model includes the central executive, visuospatial sketchpad, phonological buffer/loop, and episodic buffer.

Long-term memory includes declarative (of explicit) memories, which can be consciously retrieved, and nondeclarative (of implicit) memories, which cannot. Declarative memory includes episodic memory (stores personal experiences) and semantic memory (stores information about facts and concepts). Non-declarative memory includes procedural memory (recalls motor and executive skills), associative memory (storage and retrieval of information through association with other information), and non-associative memory (refers to newly learned behavior through repeated exposure to an isolated stimulus).

Overall, memory is a complex and essential cognitive function that plays a crucial role in learning, reasoning, and understanding.

Psychology Experiments and Theories

Asch conducted experiments on conformity, where participants tended to agree with group estimates even when they were clearly wrong. Heider introduced attribution theory and the fundamental attribution error. Milgram studied obedience by instructing participants to administer electric shocks to actors who were struggling in a learning task. Janis described groupthink, which is the tendency to pursue consensus in group decisions. On a different note, James Osterberg, who is more commonly known as Iggy Pop, performed with the rock band The Stooges.

Selective attention involves filtering external stimuli and assigning meaning to things that should get our attention. Three main models have been proposed: Broadbent’s Filter model, Treisman’s Attenuation Theory, and Deutsch and Deutsch’s Late stage model. Broadbent’s model is an early selection model that filters input based on physical characteristics, while Treisman’s model is an intermediate selection model that uses a leaky filter to weaken some stimuli but allow them through. Deutsch and Deutsch’s model is a late selection model that analyzes input for meaning before filtering occurs. Treisman’s model includes a dictionary unit that emphasizes certain words have lower thresholds for getting our attention, such as our own name.

Holmes Rahe Stress Scale (Social Readjustment Rating Scale)

In 1967, Holmes and Rahe conducted a study on the impact of stress on illness. They surveyed over 5,000 medical patients and asked them to report whether they had experienced any of 43 life events in the past two years. Each event was assigned a Life Change Unit (LCU) value, which represented its weight for stress. The higher the score, the more likely the patient was to become ill.

The first 10 life events and their corresponding LCU values are listed below.

1. Death of spouse – 100
2. Divorce – 73
3. Marital separation – 65
4. Jail term – 63
5. Death of a close family member – 63
6. Personal illness – 53
7. Marriage – 50
8. Being fired from work – 47
9. Marital reconciliation – 45
10. Retirement – 45

This scale is known as the Holmes Rahe Stress Scale of the Social Readjustment Rating Scale. It is still widely used today to assess the impact of life events on stress levels and overall health.

Personality Testing

There are two main types of personality tests: projective and objective. Projective tests aim to assess unconscious material by presenting subjects with ambiguous pictures of phrases to elicit an unconscious response. Examples of projective tests include the Rorschach Inkblot, Thematic Apperception Test, Draw-A-Person test, and sentence completion tests. On the other hand, objective tests have structured and clear questions and aims. Examples of objective tests include the Minnesota Multiphasic Personality Inventory, Sixteen Personality Factor Questionnaire (16PF), NEO Personality Inventory, and Eysenck Personality Test (EPQ).

The term ‘short-term memory’ is a less advanced term compared to ‘working memory’.

Overall, memory is a complex and essential cognitive function that plays a crucial role in learning, reasoning, and understanding.

Melanie Klein, a prominent psychoanalyst, introduced two significant concepts in her work: the paranoid-schizoid position and the depressive position. The paranoid-schizoid position is a state of mind where the individual perceives the world as fragmented, dividing it into good and bad. This position is characterized by the defense mechanism of splitting, where the individual separates the good and bad aspects of themselves and others.

On the other hand, the depressive position follows the paranoid-schizoid position and is characterized by the ability to accept ambivalence, where something can be both good and bad. This position represents a more integrated state of mind, where the individual can hold conflicting emotions and thoughts simultaneously. These concepts have been influential in psychoanalytic theory and have contributed to our understanding of the human psyche.

Narcolepsy is identified by a set of four symptoms, including excessive sleepiness, cataplexy, sleep paralysis, and hallucinations during sleep onset of awakening. While hypnagogic hallucinations have been traditionally linked to narcolepsy, both hypnagogic and hypnopompic hallucinations can occur.

Sleep Disorders

The International Classification of Sleep Disorders (ISCD) categorizes sleep disorders into several main categories and subclasses. Dyssomnias are intrinsic sleep disorders that include narcolepsy, psychopsychologic insomnia, idiopathic hypersomnia, restless leg syndrome, periodic limb movement disorder, and obstructive sleep apnea. Extrinsic sleep disorders include inadequate sleep hygiene and alcohol-dependent sleep disorder. Circadian rhythm disorders consist of jet lag syndrome, shift work sleep disorder, irregular sleep-wake pattern, delayed sleep phase syndrome, and advanced sleep phase disorder. Parasomnias include arousal disorders such as sleepwalking and sleep terrors, sleep-wake transition disorders such as rhythmic movement disorder, sleep talking, and nocturnal leg cramps, and parasomnias associated with REM sleep such as nightmares and sleep paralysis. Sleep disorders associated with medical/psychiatric disorders and proposed sleep disorders are also included in the classification.

Narcolepsy is a disorder of unknown cause that is characterized by excessive sleepiness, cataplexy, and other REM sleep phenomena such as sleep paralysis and hypnagogic hallucinations. Periodic limb movement disorder is characterized by periodic episodes of repetitive and highly stereotyped limb movements that occur during sleep. Restless legs syndrome is a disorder characterized by disagreeable leg sensations that usually occur prior to sleep onset and that cause an almost irresistible urge to move the legs. Jet lag syndrome consists of varying degrees of difficulties in initiating or maintaining sleep, excessive sleepiness, decrements in subjective daytime alertness and performance, and somatic symptoms following rapid travel across multiple time zones. Shift work sleep disorder consists of symptoms of insomnia of excessive sleepiness that occur as transient phenomena in relation to work schedules. Non 24 hour sleep wake syndrome consists of a chronic steady pattern comprising one to two hour daily delays in sleep onset and wake times in an individual living in society. Sleepwalking consists of a series of complex behaviors that are initiated during slow-wave sleep and result in walking during sleep. Sleep terrors are characterized by a sudden arousal from slow wave sleep with a piercing scream of cry, accompanied by autonomic and behavioral manifestations of intense fear. Rhythmic movement disorder comprises a group of stereotyped, repetitive movements involving large muscles, usually of the head and neck. Sleep starts are sudden, brief contractions of the legs, sometimes also involving the arms and head, that occur at sleep onset. Nocturnal leg cramps are painful sensations of muscular tightness of tension, usually in the calf but occasionally in the foot, that occur during the sleep episode. Nightmares are frightening dreams that usually awaken the sleeper from REM sleep. Sleep paralysis is a common condition characterized by transient paralysis of skeletal muscles which occurs when awakening from sleep of less often while falling asleep.

Memory Forms

Memory is the ability to store, retain, and retrieve information. There are different forms of memory, including sensory memory, short-term/working memory, and long-term memory.

Sensory memory is the capacity for briefly retaining the large amounts of information that people encounter daily. It includes echoic memory (gathered through auditory stimuli), iconic memory (gathered through sight), and haptic memory (acquired through touch).

Short-term memory is the ability to keep a small amount of information available for a short period of time. Atkinson and Shiffrin’s multistore model (1968) suggests the existence of a short-term storehouse with limited capacity. Baddeley and Hitch (1974) further developed the concept of short-term memory, which eventually became known as Baddeley’s multi-storehouse model (2000). This model includes the central executive, visuospatial sketchpad, phonological buffer/loop, and episodic buffer.

Long-term memory includes declarative (of explicit) memories, which can be consciously retrieved, and nondeclarative (of implicit) memories, which cannot. Declarative memory includes episodic memory (stores personal experiences) and semantic memory (stores information about facts and concepts). Non-declarative memory includes procedural memory (recalls motor and executive skills), associative memory (storage and retrieval of information through association with other information), and non-associative memory (refers to newly learned behavior through repeated exposure to an isolated stimulus).

Overall, memory is a complex and essential cognitive function that plays a crucial role in learning, reasoning, and understanding.
