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.

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.

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.

Flooding as a Treatment for Phobias

Flooding is a treatment method for phobias that involves directly confronting the fear and remaining in the situation until the anxiety subsides. This process is called habituation and is different from systematic desensitization. However, flooding can be challenging for patients as it produces high levels of anxiety, which can cause them to leave the situation before the fear response is extinguished. As a result, desensitization is generally preferred over flooding as a treatment method for phobias.

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.

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.

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.

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.
