4.1.4 - Psychopathology Flashcards
What are the 4 definitions of abnormality?
- Statistical infrequency
- Deviation from social norms
- Failure to function adequately
- Deviation from ideal mental health
What is statistical infrequency? example?
Occurs when an individual has a less common characteristic
Example: IQ
In any human characteristic, majority of scores are clustered around the mean. The further we go above or below that the fewer people there are attaining that score.
This is called a normal distributon - bell shaped curve
Average IQ 85-115 - lower than 70 = unusual/abnormal
Evaluation of statistical infrequency?
:) - Real life application - helps with doctors diagnosis
:( - Unusual characteristics can be positive - IQ scored over 130 just as unusual as below 70, but being intelligent isn’t undesirable. Statistical infrequency shouldn’t be used alone
:( - Not everyone benefits from a label - may have a negative effect on the way others view them and how they view themselves - people don’t need to be diagnosed as intellectually disabled
What is deviation from social norms? example?
- Person behaving in a way that is different from how we expect them to behave
- Usually noticeable
Example: Antisocial Personality Disorder (impulsive, aggressive, irresponsible)
Evaluation of deviation from social norms?
:) - Real life application - Can be used to diagose disorders and is used in clinical practice - shows it has value in psychiatry
:( - Not a sole explanation - Other factors to consider
:( - Cultural relativism - Social norms vary between cultures and generations
:( - Can lead to human rights abuses - can be used to maintain control over minority groups e.g. drapetomania in black slaves
What is failure to function adequately? Example?
- An individual cannot cope with everyday life
- They are unable to maintain basic standards of nutrition and hygiene
- Unable to hold down a job or maintain relationships
Example: Rosenhan and Seligman suggested some signs to determine when someone is not coping:
- Not conforming to standard interpersonal rules
- Person experiences severe personal distress
- Behaviour becomes irrational or dangerous to themselves or others
Evaluation of failure to function adequately?
:) - Consider’s the patient’s POV - acknowledges experience of the individual
:) - Represents threshold for help - means treatment and services can be targeted to those who need them most
:( - Is it simply just a deviation from social norms? - hard to define between the two: not having a job may seem like failing to function for some people but not others
:( - Labelling and social control - “Failing to function” as a label could add to someone’s issues and lead to a self-fulfilling prophecy
What is deviation from ideal mental health?
- Ignore what makes someone abnormal and instead think about what makes anyone “normal”
- Once we have an idea of what ideal mental health looks like, we can see who deviates from this
Marie Jahoda (1958) suggested that the absence of mental illness is not a sufficient indicator of mental health
What is the criteria of good mental health according to Jahoda (1958)?
- We have no symptoms of distress
- We are rational and can perceive ourselves accurately
- We self-actualise (reach our potential)
- We can cope with stress
- We have a realistic view of the world
- We have good self-esteem and lack guilt
- We are independent of other people
- We can successfully work, love and enjoy our leisure
Evaluation of deviation from ideal mental health?
:) - Comprehensive - Covers a broad range of criteria for mental health
:( - Cultural relativism - Some of the ideas of Jahoda are specific to European and North American cultures e.g. collectivist cultures would see being independent as a negative thing. It is hard to apply to other cultures
:( - Sets unrealistically high standards for mental health - most people are probably seen as abnormal against this criteria
What is a phobia? (DSM-5 definition)
Excessive fear and anxiety is triggered by an object,place or situation
(Extent of fear is out of proportion to any real danger presented by the phobic stimulus)
Categories of phobias?
Specific phobia - Phobia of an object or situation
Social anxiety - Phobia of a social situation such as public speaking or using a public toilet
Agoraphobia - Phobia of being outside or in a public space
3 types of characteristics of phobias?
- Behavioural
2 .Emotional
3 .Cognitive
Behavioural characteristics of phobias?
- Panic (crying, screaming, running away)
- Avoidance (effort to avoid stimulus - can be hard in daily life)
- Endurance (remains in presence of stimulus but experiences high levels of anxiety)
Emotional characteristics of phobias?
Anxiety
- unpleasant state of high arousal, prevents relaxing or positive emotion
- can be long term
- unreasonable
- very strong emotional response to something that poses little harm
Cognitive characteristics of phobias?
- Selective attention to the phobic stimulus
- Irrational belief
- Cognitive distortions
What does Mowrer’s two-process model suggest about the formation of phobias?
(behaviourist approach)
- Phobias are acquired using classical conditioning
- Phobias continue because of operant conditioning
e.g. Watson and Raynor’s Little Albert study
How are phobias maintained through operant conditioning?
- When we avoid a phobic stimulus we escape the fear
- Reinforced avoidance behaviour - phobia is maintained
- This is negative reinforcement
Evaluation of the two-process model?
:) - Explanatory power - important implications for therapy: explains why patients need to be exposed to feared stimulus
:( - Not all avoidance is motivated by anxiety reduction - some avoidance behaviour may be motivated by positive feelings of safety (positive reinforcement)
:( - Incomplete - doesn’t take into account biological preparedness (phobias of things which may have been a danger in our evolutionary past)
:( - There are phobias that don’t follow trauma
:( - Ignores cognitive aspects e.g. selective attention, irrational beliefs
What are the 2 behaviourist treatments of phobias?
Systematic desensitisation
Flooding
What is systematic desensitisation?
- Gradually reduces anxiety through classical conditioning
- If sufferer can learn to relax in presence of phobic stimulus they will be cured
Involves:
- Counterconditioning - new response is learned (stimulus paired with relaxation instead of anxiety)
- Reciprocal Inhibition - impossible to be afraid and relaxed at the same time - one emotion prevents the other
What 3 processes are involved in systematic desensitiation?
- Anxiety hierarchy
- Relaxation
- Exposure
Evaluation of systematic desensitisation?
:) Very effective - shown by Gilroy (2003)
:) - Suitable for a diverse range of patients - learning difficulties may make it hard to understand what is happening during flooding, and so SD is more appropriate
:) - Acceptable to patients - does not cause the trauma that flooding does and leads to lower refusal and attrition rates
:( - Time consuming as can take many sessions
:( - May not be appropriate for more generalised phobias (e.g.social phobia) where there is no obvious target behaviour so difficult to devise hierarchy
:( - Progress in therapy may not generalise outside of clinical setting - when the person must face their fear without support from therapist
What is flooding?
Exposes patients to stimulus without gradual build up
Immediate exposure
How does it work?
- stops phobic responses very quickly
- no avoidance - patient learns stimulus is harmless
- classical conditioning -extinction
- conditioned stimulus encountered without unconditioned stimulus
- conditioned stimulus no longer produces conditioned response
