Psychopathology Flashcards
Who are the named psychologists for psychopathology?
Beck and Ellis
What is abnormal defined as?
Those who are suffering from psychological disorders or mental illnesses
What are the 4 ways to identify abnormality?
Deviation from social norms, failure to function adequately, statistical infrequency, deviation from ideal mental health
What are social norms?
What is considered acceptable, expected ways of behaving, like a set of behavioural rules
What are examples of implicit and explicit social norms?
Implicit (unspoken) e.g. not laughing at a funeral
Explicit (law) e.g. streaking in public
Why is an individual defined as abnormal according to the deviation from social norms definition?
If they deviate from the social norms, their behaviour is abnormal
What are the 3 weaknesses of defining abnormality using deviation from social norms?
Doesn’t account for choice, e.g. being vegan or following a minority religion.
Difficult to apply since social norms change over time e.g. being gay or unmarried mothers
Open to abuse e.g. abnormal in Russia if held different political beliefs from the ruling party, so can be used as a form of social control
What is functioning adequately?
Managing tasks necessary to everyday life
When is behaviour classed as abnormal in failure to function adequately?
They cannot cope with the daily demands AND distress is being caused to themselves or others
What are the 6 features of abnormality Rosenhan and Seligman suggested? (failure to function adequately)
1) Personal distress
2) Maladaptive behaviour
3) Unconventionality
4) Observer discomfort
5) Violation of moral and social standards
6) Irrationality
How many features of abnormality are needed to be present in order to be classed as abnormal? (failure to function adequately)
The more features present, the more abnormal an individual is
What are the 3 weaknesses of defining abnormality using failure to function adequately?
Doesn’t account for the individual’s circumstances, sometimes it is normal to fail to function adequately.
Vague - unclear how extreme the behaviour has to be to be abnormal.
Ethnocentric - based on Western culture
What is a strength of defining abnormality using failure to function adequately?
Practical applications - clinicians use this definition as it provides an objective and quantitative measurement of functioning, helps patients access treatments quicker as they are diagnosed
When is behaviour classed as abnormal in statistical infrequency?
Behaviour that is statistically infrequent or very rare is abnormal
On a normal distribution curve, how many standard deviations away is statistical infrequency? (+ percentages)
More than 2 σ which is less than 5% (both sides)
What are the 3 weaknesses of defining abnormality using statistical infrequency?
Does not account for desirability e.g. high IQ, so doesn’t identify behaviours in need of treatment.
Some abnormal behaviour isn’t rare e.g. 37% teenage girls report low mood + high stress.
The cut-of point is subjective, so definition is subjective and depends on individual opinion
What is a strength of defining abnormality using statistical infrequency?
Practical applications - all patient assessments include some measurement of severity of symptoms against statistical norms
When is behaviour classed as abnormal in deviation from ideal mental health?
If they don’t have all 6 characteristics of ideal mental health
What are the 6 characteristics of ideal mental health?
1) Positive self-attitudes - self-esteem + identity
2) Self-actualisation - full potential
3) Resistance to stress - cope, not immune
4) Autonomy - self-directed
5) Accurate perception of reality - rational
6) Mastery of the environment - looking after self/functioning (love, work, etc)
What are the 3 weaknesses of defining abnormality using deviation from ideal mental health?
Sets bar too high, most people would be classed as abnormal, idealised set of expectations, not useful.
Not clear how many need to be lacking.
Ethnocentric - self-actualisation is selfish in some collectivist cultures, besides very few people achieve it
What is a strength of defining abnormality using deviation from ideal mental health?
It offers a positive approach to identifying mental illness, more ethical
What is a phobia?
An extreme and irrational fear of a specific stimulus that produces a conscious avoidance of the source of the fear which interferes with daily life
What are clinical characteristics?
Symptoms (behavioural, emotional, and cognitive)
What are behavioural characteristics/symptoms?
What the person does
What are emotional characteristics/symptoms?
What the person feels
What are cognitive characteristics/symptoms?
What the person thinks
What are the 2 behavioural characteristics of a phobia?
Avoidance of stimulus.
Fainting or freezing when with stimulus.
These must interfere with other daily activities
What are 2 emotional characteristics of a phobia?
Excessive, unreasonable, persistent fear/anxiety/panic when in presence/anticipation of stimulus.
Guilt as they stop doing other things/activities
What are 3 cognitive characteristics of a phobia?
Recognition of irrational nature.
Can’t be helped by rational arguments.
Selective attention (only focusing on stimulus)
What approach is used to explain/treat phobias?
Behavioural approach
How do phobias occur?
They are learnt
Who came up with the two-process model to explain how a phobia develops and is maintained?
Mowrer
What is the first step of the two-process model called?
The Acquisition
How are phobias developed?
Through classical conditioning - they associate a reflex response of fear to a neutral stimulus, the response of fear transfers to the neutral stimulus
Often needs repeated exposure (around 5 times)
How are phobias manitained?
Through operant conditioning - negative reinforcement of avoidance
What is the supporting evidence of the behavioural approach to explaining phobias?
Watson and Rayner: Little Albert’s fear of white rats.
They taught Albert to fear white rats.
They made a loud noise every time Albert saw the white rat, he then generalised this fear to anything white and furry
What are 2 criticisms of the behavioural approach to explaining phobias?
Challenging evidence: Munjack found only 50% of people with a driving phobia had had a frightening experience with a car.
Reductionist - heavily on nurture side of nature vs nurture debate, ignores biological evidence: evolution
What are the practical applications of the behavioural approach to explaining phobias?
Development of successful, effective behavioural therapies: systematic desensitisation (75%) and flooding (65%), helps economy as people able to work
What are the treatments for phobias?
Systematic Desensitisation and Flooding
Which aspect of the behavioural approach is systematic desensitisation based on?
Classical conditioning
What does SD involve?
Gradual exposure to their feared object/situation, based on counterconditioning and reciprocal inhibition
What is counterconditioning?
Classical conditioning where the new response (relaxation) is counter to the original response (fear)
What is reciprocal inhibition?
The notion that we cannot experience 2 incompatible/opposite emotional states at the same time (fear and relaxation)
What are the 3 main stages of SD?
Relaxation techniques learnt
Hierarchy of fear created
Gradual exposure (following the hierarchy of fear using the relaxation techniques)
What happens in the first stage of SD?
Relaxation techniques are learnt, e.g. deep breathing, visualising a peaceful scene, or progressive relaxation which is focussing on tightening muscles then relaxing throughout body
What happens in the second stage of SD?
The client creates a hierarchy of fear which is a list of situations/scenarios involving their feared stimulus, ranked from least to most frightening
What happens in the third stage of SD?
The client goes through their hierarchy of fear from least to most frightening, only moving on when completely relaxed/when the client wants to, using the relaxation techniques.
This can be in vivo (in real life) or in vitro (in brain)
How do we evaluate treaments?
Effectiveness and Appropriateness
What does the effectiveness of treatments refer to?
Does it work/was it successful?
What does the appropriateness of treatments refer to?
Is it right for the client/is it ethical/does it suit them?
What is the evidence to suggest SD is effective? (2 studies)
McGrath found 75% were successfully treated.
Gilroy found both 3 months and 33 months after treatment the SD group showed less fearful responses (arachnophobia)
What is the evidence to suggest some parts of SD are not effective? (not a specific study)
In vitro less effective than in vivo
What is the evidence to suggest SD is not effective in the long-term?
Craske & Barlow found 50% relapsed after 6 months
