Psychopatholgy (abnormality) Flashcards
Define cultural relativism (Definitions of abnormality)
- The view that behaviour cannot be judged properly unless it is viewed in the context of the culture in which it originates
Define deviation from social norms (Definitions of abnormality)
- Abnormal behaviour is seen as deviation from unstated social rules about how people should behave
- Anything that violates these rules is considered abnorma
Define DSM (Definitions of abnormality)
- Diagnostic and statistical manual of mental disorders
- A list of mental disorders that is used to diagnose mental disorders
- For each disorder a list of clinical characteristics is given, i.e. the symptoms that should be looked for
Define statistical infrequency (Definitions of abnormality)
- Abnormality is defined as those behaviours that are extremely rare, i.e. any behaviour that is found in very few people is regarded as abnormal
Outline statistical infrequency (Definitions of abnormality)
- A way in which abnormality can be defined
- We define normality by referring to typical values
- E.g the average shoe size for 12 year old
- It involves defining what is most common or normal, then we also have an idea of what is not common i.e. abnormal
- This is done by analysing data from different populations and identifying the most common values
- Anything that is far away from these values is statistically infrequent
Outline deviation from social norms (Definitions of abnormality)
- In any society there are stands of acceptable behaviour that are set by the social group, and adhered to by those socialised into that group
- Anyone who behaves differently from these social norms is called as abnormal
- An example of social norms is politeness and it helps us with our interpersonal relations
- people who are being rude are considered to be behaving in a socially deviant way as others find it difficult to interact with them
- Some rules about deviation from social norms are implicit and some are enforced by the law
- e.g. laughing at a funeral or disorder in public both deviations from social norms
Example of deviation from a social norm (Definitions of abnormality)
- In the past, homosexuality was classified as abnormal and regarded as a mental disorder
- it was also a mental disorder
- This judgement was based on social deviation
- based on what behaviours are considered to be acceptable
Evaluation: Definitions of abnormality (Evaluation of statistical infrequency- some abnormal behaviour is desirable)
- An objection to this approach is that there are many abnormal behaviours that are actually quite desirable
- For example few people have an IQ greater than 150 however having a high IQ IS not undesirable
- Alternatively, there are some normal behaviours that are undesirable for example experiencing depression
- Using statistical infrequency means that we cannot distinguish between desirable and undesirable behaviours
- This is necessary for identifying which behaviours need treatment
Evaluation: Definitions of abnormality (evaluation of deviations from social norms- varies as times change)
- A limitation of the concept of deviation from social norms is that it varies as times change
- What is socially acceptable now may not have been 50 years ago
- 50 years homosexuality was included under sexual and gender identity disorders but today it is more accepted
- In Russia, 50 years ago, anyone who disagreed with the state was at risk of being regarded as insane and placed in a mental institution
- This shows that deviation from social norms can be defined unfairly
- As suggested by Thomas Szasz, the concept of mental illness may be used as a way to include non-conformists from society
Evaluation: Definitions of abnormality (Cultural relativism)- statistical infrequency
A limitation lies with the attempts to define abnormality in terms of social norms which is relative to the group of people around then
- In the case of statistical infrequency, behaviours that are statistically infrequent in one culture may be statistically more frequent in another e.g. symptoms of schizophrenia is claiming to hear voices
- However this experience is common is some cultures
- Therefore the model is culturally relative
Evaluation: Definitions of abnormality (Cultural relativism)- deviation from social norms
- Attempting to define abnormality in terms of social norms is obviously bound by culture because social norms are defined by culture
- Classification systems, such as the DSM are almost entirely based on the social norms of the dominant culture
- Cultural relativism has become acknowledged and the revised DSM makes reference to cultural contexts in many areas of diagnosis
- In the section on panic attaks crying may be a symptom in one culture whereas difficulty breathing may be a primary symptom in others
- No universal standards for labelling a behaviour as normal
The behavioural approach to treating phobias: Systematic desensitisation
- One of the reasons that phobias may persist is that phobics avoid the phobic stimulus and therefore
- there is no opportunity to learn that their feared stimulus is not so fearful after all
- Joseph Wolpe (1958) developed a technique were phobics were introduced to the feared stimulus gradually
The behavioural approach to treating phobias: (SD) Counterbalancing
- The basis of the therapy is counterbalancing
- The patient is taught a new association that opposes the original association
- Through classical conditioning, the patient is taught to associate the phobic stimulus with anew response, i.e. relaxation instead of fear
- In this way their anxiety is reduced- they are desensitised
- Wolpe also called this βreciprocal inhibitionβ because this response of relaxation inhibits the response of anxiety
The behavioural approach to treating phobias: (SD) Relaxation
- The therapist teaches the patient relaxation techniques
- Relaxation can be achieved by the patient focusing on their breathing and taking slow, deep breaths
- When we are anxious we breathe quickly, so slowing this down help us to relax
- Being mindful of βhere and nowβ can help, as well as focusing on a particular object or visualising a peaceful scene
- Progressive muscle relaxation is also used where one muscle at a time is relaxed
The behavioural approach to treating phobias: (SD) Desensitisation hierarchy
- SD works by gradually introducing the person to the feared situation one step at a time so it is not as overwhelming
- At each stage the patient practices relaxation so the situation becomes more familiar, less overwhelming and their anxiety diminishes
The behavioural approach to treating phobias: Flooding
- An alternative to the gradual progression through a hierarchy, as used in systematic desensitisation, is to just have one long session where the patient experiences their phobia at its worst while at the same time practising relaxation
- The session continues untill the patient is fully relaxed
- For example a patient who is scared of heights of taken up a tall building
The behavioural approach to treating phobias: Flooding in practice
- The procedure can be conducted in vivo (actual exposure) or virtual reality can be used
- As with SD, the first step is to learn relaxation techniques
- Then these techniques are applied in one session in the presence of the most feared situation
- This usually lasts two or three hours
- A persons fear response has a time limit
- As adrenaline levels naturally decrease, a new stimulus-response link can be learned between feared stimulus and relaxation
Evaluation: (The behavioural approach to treating phobias) Effectiveness of SD
- Research has found that SD is successful for a range of phobic disorders
- For example, McGrath reported that about 75% of patients with phobias respond of SD
- The key to success appears to lie with actual contact with the feared stimulus,so in vivo techniques are more successful than ones just using pictures or imagining the feared stimulus
- Often a number of different exposure techniques are involved- in vivo and also modelling, where the patient watches someone else who is coping well with the feared stimulus
Evaluation: (The behavioural approach to treating phobias) (SD) Strengths of behaviour therapies
- Behavioural therapies for dealing with phobias are generally relatively fast and require less effort on the patients part than other psychotherapies
- For examp,le CBT requires a lot of willpower from the patient in trying to understand their behaviour and apply these insights
- This lack of βthinkingβ means that the technique is also useful for people who lack insight into their motivations or emotions
- A further strength of SD is that it can be self-administered, a method which has proven to be successful especially with social phobias
Evaluation: (The behavioural approach to treating phobias) (Flooding) Individual differences
- Flooding is not for every patient
- It can be a highly traumatic procedure
- Patients are made aware of this before hand, even then, they may quit during the treatment, which reduces the ultimate effectiveness of the therapy for some people
Evaluation: (The behavioural approach to treating phobias) (Flooding)Effectiveness
- For those who do choose flooding as a treatment and do stick with it, it appears to be an effective treatment and is relatively quick (compared to CBT)
- For example Choy reported that both SD and flooding were effective but flooding was the more effective of the two at treating phobias
- On the other hand, another review concluded that SD and flooding were equally effective in the treatment of phobias
Evaluation: (The behavioural approach to treating phobias) Relaxation may not be necessary
- It may be that the success of both SD and flooding is more to do with exposure to the feared situation than relaxation
- It might also be that the expectation of being able to cope with the feared stimulus is most important
- For example , Klein compared SD with supportive psychotherapy for patients with either social or specific phobias
- They found no difference in effectiveness suggesting that the βactive agentβ in SD or flooding may simply be the generation of hopeful expectancies that the phobia can be overcome
Failure to function adequately: (Definitions of abnormality)
- from an individuals point of view, abnormality can be judged in terms of not being able to cope with everyday tasks i.e. Failure to function adequately
- Not functioning adequately causes distress and suffering for the individual, and/or may cause distress for others
- It is important to include βdistress to othersβ because, in the case of some mental disorders, the individual may not be distressed at all
- People with schizophrenia generally lack awareness that anything is wrong but their behaviour (hallucinations, believing that they are being persecuted) may well be distressing to others
- There may be situations where a person is not coping with everyday life in a βnormalβ way- for example, a person may be content living in unwashed clothes and not having a regular job
- If this doesnβt cause distress cause distress to self or others then a judgement of abnormality is inappropriate
