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.

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.

Intervention-Causation Fallacy

The intervention-causation fallacy is a common mistake where people assume that a cure proves a cause. For instance, if antidepressants alleviate symptoms of depression, it does not necessarily mean that depression has a biological cause. It is important to note that just because a treatment works, it does not necessarily mean that it is addressing the root cause of the problem. Therefore, it is crucial to be cautious when making assumptions about causation based on interventions. By avoiding this fallacy, we can ensure that we are accurately identifying the underlying causes of problems and developing effective solutions.

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.

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.

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.

Maslow differentiated between two types of needs: deficiency needs (D-needs) and being needs (B-needs). While B-needs enable us to achieve our highest potential, they can only be met once the D-needs have been fulfilled. The lower four levels of Maslow’s hierarchy of needs correspond to D-needs.

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.

The women’s shouting, which is an unpleasant stimulus, serves as a positive punisher that reduces the likelihood of the behavior (speeding) occurring again. This is distinct from reinforcement, which involves the introduction of a positive stimulus to increase the likelihood of a behavior being repeated.

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 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.

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. For more information, please refer to Edwards JW’s article Indigenous Koro, a genital retraction syndrome of insular Southeast Asia: a critical review published in Cult Med Psychiatry in 1984.

The Hawthorne effect is a type of bias that occurs when individuals alter their behavior because they believe they are being observed. The halo effect is a cognitive bias where one’s perception of a trait is influenced by their perception of another trait, such as assuming someone with glasses is intelligent. The Forer effect explains why people give high accuracy ratings to personality descriptions that are actually vague and general enough to apply to many people, as seen in practices like astrology. The interloper effect is the tendency to view third-party consultation as objective. The practice effect refers to the impact of past experience on taking a test again, resulting in higher scores, especially when the interval between tests is short.

The Hawthorne Effect and Its Impact on Research

The Hawthorne effect is a type of observer bias that occurs when individuals modify their behavior because they believe they are being observed. This phenomenon can have a significant impact on research outcomes, as subjects may alter their actions of responses in an attempt to please the observer of researcher. For instance, if a person knows they are being watched while performing a task, they may complete it more quickly of with greater accuracy than they would otherwise. As a result, researchers must be aware of the Hawthorne effect and take steps to minimize its influence on their studies. Failure to do so can lead to inaccurate of misleading results, which can have serious consequences for the validity of the research.

The child’s ability to confront his fear is facilitated by his relaxation while sitting with his mother, which exemplifies the use of reciprocal inhibition in systematic desensitization.

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.

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.

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.

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.

Theories of Emotion

In membership exams, four main theories of emotion are commonly discussed: James-Lange theory, Cannon-Bard theory, Singer-Schachter theory, and Lazarus theory. The key to understanding the differences between these theories is to identify where the stimulus for the emotion arises.

According to the James-Lange theory, emotions occur as a result of bodily sensations. For instance, if you see a big dog, your heart races, and you feel afraid. This theory proposes that certain external stimuli stimulate specific sensory organs, leading to a particular emotion. The sequence of events suggested by this theory is as follows: event – arousal – interpretation – emotion. In other words, the stimulus for emotion arises from physical sensations.

The Cannon-Bard theory, also known as the thalami theory, proposes that when an event occurs, one experiences an emotion at the same time as physiological changes. The stimulus for emotion arises simultaneously in the body and the mind.

The Singer-Schachter theory, also known as the two-factor theory, suggests that emotions result from both physiological changes and the context. For example, if your heart is racing, and you are about to have an exam, you label yourself as afraid. However, if your heart is racing, and you are about to kiss your partner, you label your emotional state as excited. The stimulus for emotion arises via a combination of physical sensations and the mind’s appraisal of them.

Finally, the Lazarus theory proposes that a thought is required before an emotion occurs. For instance, if you see a big dog, you think it is going to bite you, and you feel afraid. The stimulus for emotion arises from the mind.

In summary, these theories offer different perspectives on the relationship between physical sensations, cognitive processes, and emotions.

As long as you comprehend the distinction between quantitative (involving a specific measure) and qualitative (involving a description), you should be able to answer this question without difficulty.

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).

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.

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.

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. 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.

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.

While quality adjusted life years (QALY) are a utilitarian measure, it would be extreme to suggest that individuals with illnesses that require expensive treatments should not be treated solely based on the cost-benefit analysis. The general population does not strictly adhere to utilitarian principles, and therefore, The National Institute for Health and Care Excellence (NICE) considers other factors such as justice and the availability of alternative treatments for a particular condition in addition to the cost per QALY when making recommendations.

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.

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.

History of major works in psychiatry
Michel Foucault – Madness and civilization
Sigmund Freud – The interpretation of dreams, Beyond the Pleasure Principle, The Psychopathology of everyday life
Thomas Szasz – The myth of mental illness
Erving Goffman – Asylums, The Presentation of Self in Everyday Life
Ronald Laing – The divided self
Emile Durkheim – Le suicide. Durkheim proposed social causes for suicide. Until his work was published, suicide had been thought of as an individual act only.
Tom Main – The Ailment
Jerome Frank – Persuasion and Healing
George Brown and Tirril Harris – Social origins of depression

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.

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.

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.

Throughout his career, Szasz contended that mental illness is merely a metaphor for difficulties in human existence, and that mental illnesses lack the objective reality of physical ailments like cancer. He opposed many aspects of the contemporary psychiatric system in developed countries.

Antipsychiatry is a movement that emerged in the 1960s and challenges the traditional medical model of mental illness. It argues that mental illnesses are not biological of medical conditions but rather social constructs that reflect deviations from social norms. The movement has been associated with several famous figures, including Thomas Szasz, R.D. Laing, Michel Foucault, and Franco Basaglia. These individuals have criticized the psychiatric profession for its use of involuntary hospitalization, medication, and other forms of coercion in the treatment of mental illness. They have also advocated for alternative approaches to mental health care, such as community-based care and psychotherapy. Despite its controversial nature, the antipsychiatry movement has had a significant impact on the field of mental health and continues to influence the way we think about and treat mental illness today.

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.

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.

Power Theory

French and Raven (1959) developed the 5 base theory of power, which identifies five types of power. These include legitimate power, which is held by an individual in an organization, referent power, which is held by a person with charisma who people gravitate towards, expert power, which is held by a person with specialist skills of knowledge, reward power, which is held by a person in a position to provide rewards, and coercive power, which is held by a person who has the ability to apply negative influences such as demotion. Other terms to be aware of include outcome power, which is the power of a person to bring about outcomes, social power, which is the power of a person to influence others so that they will bring about outcomes, and counterpower, which is the power of the oppressed to counterbalance the elite.

– Different structures are involved in working memory.
– The prefrontal cortex is the main structure that is expected to be known.
– The hippocampus main role is to consolidate short-term memories to long-term storage.

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.

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.

According to Gelder (2009), semantic memory pertains to knowledge of facts and concepts that can be consciously recalled. Unlike episodic memory, which is also a type of declarative memory, semantic memory is not tied to any particular personal experience.

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 frontal lobe contains the prefrontal gyrus and gyrus rectus, while the midbrain floor is composed of the tegmentum. Additionally, the hippocampus, which is crucial for memory, is located within the medial temporal lobe.

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.

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).

It should be noted that there is some debate over the origins of certain terms. 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.

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.

Occupational Classification:

The Office of Population Censuses and Surveys has developed a social and occupational classification system that categorizes individuals based on their employment status and level of skill. The system includes six social classes, ranging from unemployed of student (social class 0) to professional (social class I).

Social class I includes individuals who hold professional positions, such as doctors, lawyers, and engineers. These individuals typically have advanced degrees and specialized training in their field.

Social class II includes intermediate positions, such as managers, supervisors, and technicians. These individuals may have some level of specialized training of education, but not to the same extent as those in social class I.

Social class III includes skilled, manual, of clerical positions, such as electricians, mechanics, and administrative assistants. These individuals have a high level of skill in their field and may require some level of training of certification.

Social class IV includes semi-skilled positions, such as factory workers, machine operators, and retail salespeople. These individuals may have some level of training of experience, but not to the same extent as those in social class III.

Social class V includes unskilled positions, such as laborers, cleaners, and agricultural workers. These individuals typically do not require any specialized training of education and may perform manual labor of basic tasks.

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.

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.

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.

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.

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.

The objective of the book ‘Social origins of Depression’ was to identify the societal elements that play a role in the onset of depression, particularly in women.

The Bystander Effect: Theory and Examples

The bystander effect, also known as the Genovese effect, suggests that the likelihood of someone helping in a situation is inversely related to the number of people present. This means that a person is more likely to help if there are fewer witnesses. The term Genovese effect comes from the case of Kitty Genovese, who was sexually assaulted and killed in front of a large apartment building. Despite 38 neighbors hearing her screams, no one called the police. However, the facts of this story have been largely shown to be inaccurate.

Bystanders are less likely to help if there are many other people present, if the perpetrator is present, if the costs of intervention are physical, and if the situation is perceived as dangerous. On the other hand, bystanders are more likely to help if they are male and if they know the person in need of help. Overall, the bystander effect has been shown to be a valid concept, as demonstrated by research studies.

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.
