psychopathology Flashcards
What is statistical infrequency ?
Abnormality is defined as those behaviours that are extremely rare ie any behavior that is found in very few people is regarded abnormal
What is deviation from social norms ?
Anyone who deviates from socially created norms ( standards of acceptable behaviour in society) is classed as abnormal
Some rules about unacceptable behaviour are implicit ie not laughing at a funeral while others are policed by law
Not all abnormal behaviours are undesirable
For example very few people have an IQ over 150 but this abnormality is desirable. Therefore using SI to define abnormality means we are unable to distinguish between desirable and undesirable behaviours
How is the definition of abnormality in terms of statistical infrequency culturally dependent ?
Behaviours that are statistically infrequent in one culture may be common in others ie one of the symptoms of schizophrenia is claiming to hear voices, however this is common in some cultures.
There are no universal rules of labelling a behav as abnormal
Social norms are susceptible to change
For example homosexuality is acceptable in most countries in the world but in the past it was viewed as a disorder until 1973 So deviation to social norms can vary.
Lacks temporal validity
Deviation is related to context and degree
judgements on deviance from social norms are often related to the context of behaviour. For example a person wearing next to nothing on a beach is regarded as normal while the same outfit in a classroom or formal gathering is regarded as abnormal.
Therefore social deviation on its own cannot offer a complete definition of abnormality
Defining abnormality based on social norms is culturally relative
this is because behaviours which are social norms in one culture may not be considered normal in others. Ie hearing voices is a good example of this.
Using statistics is an objective and unbiased way of defining abnormality
For example finding people in a population more than 2SDs from the mean can be done objectively and without bias
What is failure to function adequately ?
A person is considered abnormal if they are unable to cope with the demands of everyday life
What was Rosenhan and Seligman’s criteria for FFA
- suggested characteristics in 1989 that suggest FFA
Suffering, maladaptivenessss, unconventionality. Loss of control, irrationality, causes observer discomfort, violates moral/social standards
What was Rosenhan and Seligman’s criteria for FFA
- suggested characteristics in 1989 that suggest FFA
Suffering, maladaptivenessss, unconventionality. Loss of control, irrationality, causes observer discomfort, violates moral/social standards
What is a strength of FFA
Takes patient perspective into account eg criteria of suffering so can be considered quite subjective
however can be measured objectively using WHODAS which assesses someone’s ability to function
considers six key aspects: understanding and communicating, getting around, self care, getting along with people, life activities and participation is society
Sometimes FFA is normal
For example after a bereavement. Ironically, ma be considered more abnormal if they functioned normally
Additionally many ppl engage in behaviour that is maladaptive/ harmful to self but they are not classed as abnormal ie adrenaline sports and smoking
Cultural relativism of FFA
Different cultures may have different ideas about wat it means to function in daily life. may explain why lower class and non white patients whose life style differs from the domonant culture are often dignosed with mental disorders ( by standards of dominant culture they aare unable to function adequately
What is the deviationtion from ideal metal health ?
Deviating from having a good mental health
What characteristics did Jahoda suggest are necessary for good mental health ?
Positive view of self, capability of growth and development, autonomy and independence, positive friendships and relationships, able to meet demands of everyday life
Jahoda’s criteria sets the bar too high
Strictly applied very few people actually meet these criteria that everyone ends up classed as abnormal and so concept becomes meaningless
Also many of the criterias are hard to measure ie how do you assess someone’ capability for personal growth ?
Jahoda’s criteria provides useful targets
Targets for goal setting and treatment eg in CBT targets are set
Deviation from ideal mental health is a positive approach
Focuses on the positives rather than the negatives. Jahoda’s criteria focuses on what is desirable rather than what is undesirable. Have had some influence with the positive psychology movement in the humanistic approach.
Jahoda’s mental health criteria are culture bound
The goal of self actualisation is more relevant to members of individualist cultures but not collectivist cultures where the needs of the group are promoted.
What are two methods psychologists use to diagnose mental disorders ? What is the limitation of these methods
DSM and ICD
Include a list of symptoms which can be used as a tool for diagnosis
Too reductionist as people can lie about their symptoms
What are specific phobias ?
a fear of a specific object or situation
Ie animal type, heights, blood, enclosed spaces etc
What are social phobias ?
Extreme concern about one’s own behaviour and the reactions of others
What are the behavioral characteristics of phobias ?
- avoidance of any social situation as they cause anxiety ( this especially happens with a social phobia or agoraphobia)
- altering the behavior to avoid the feared object or situation
- general restlessness and easily startled
What are cognitive characteristics of phobias ?
- the irrational thought processes that occur which may involve catastrophising
- selective attention to feared object ie an arachnophobic may scan top corners of a room for cobwebs
- recognition that the fear is excessive
What are the emotional characteristics of phobias ?
- marked and persistent fear of an object or situation
- feelings of anxiety and panic
Emotions tend to be out of proportion to the actual “threat” posed
Who proposed the two process model of how phobias are learnt ?
Orval Hobart Mowrer ( 1947)
What are the two stages of the two process model ?
classical and operant conditioning
describe the classical conditioning step of the two process model ?
phobia being acquired through association - association between neutral stimulus and and unconditioned stimulus causes a conditioned response to be learnt
neutral stimulus might be a furry object and the unconditioned stimulus - loud noise. The unconditioned response being fear.
Pairing these together causes the furry object ( neutral stimulus) to produce a fear response - conditioned response.
What is the operant conditioning step of two process model of acquiring phobias ?
- chances of a behavior being repeated increase if the outcome is rewarding
- with a phobia, the avoidance of phobic stimulus reduces fear and is therefore reinforcing. ( an example of neg reinforcement)
- individ avoids anxiety created by phobic stimulus by avoiding it completely
How else can phobias be acquired ?
- modelling the behaviour of others
ie seeing a parent respond to a spider with fear may lead to a similar behavioral response in a child because behaviour appears rewarding ie fearful person gets attention
research support for classical conditioning being involved in phobia acquisition
but not necessary for phobias
People with phobias often do remember a specific incident when their phobia appeared ie getting bitten by a dog or having a panic attack in a social situation ( Sue et al 1994
however, Sue et al suggest that different phobias may be result of different processes ie agoraphobics more likely to explain their disorder in terms of a specific incident while arachnophobics more likely to state modelling to be the cause.
Two process model is an incomplete explanation
a phobia isn’t always created when a neutral stimulus is associated with a fearful experience
research has found that not everyone bitten by a dog develops a fear of them ( Di Nardo et al 1988)
Could be explained by diathesis stress model which proposes some ppl have a genetic vulnerability for inheriting phobias, but this disorder only manifests if triggered by live event ie dog biting you
so dog bites would only lead to phobias for people who have this vulnerability
Support for social learning explanation
experiment by Bandura and Rosenthal where model acted in pain every time a buzzer sounded
later, participants who had observed this showed an emotional response to buzzer, showing that modeling others can lead to phobia acquisition
Two process model ignores cognitive factors
- two process model ignores the cognitive approach completely which states that irrational thoughts can lead to phobias
ie a person in a lift might think that they will become trapped in a lift and suffocate ( an irrational thought)
such thoughts can lead to extreme anxiety and trigger phobia
