PAPER 1- TOPIC 4 PSYCHOPATHOLOGY ✅ Flashcards
describe statistical deviation (infrequency) as a definition of abnormality
when an individual has a less common and characteristics than most of the population, based on stats and frequencies
-unusal = abnormal
what can be used to identify abnormal behaviour using statistical deviation
- measures of central tendency (mean, median, mode)
- statistical deviation from average of a normal distribution curve
example of statistical infrequency
IQ scores on a normal distribution curve, can identify if an individual has intellectual disability
(bottom 2% of scores)
Describe deviation from social norms as a definition of abnormality
someone behaves in a different way to the accepted standards in a society
define social norm
what do they vary in
- a rule/judgement held by a social group of how people should behave
- cultures and generations
example of what is anti social personality disorder
characteristics of it
how it is an example of deviation from social norms
- anti social personality disorder (psychopathy)
- —> characteristics are being impulsive, aggressive and lacking empathy
- they are unable to conform to social and ethically normal behaviour
- so psychopaths are seen as abnormal in a range of cultures
Describe failure to function adequately as a definition of abnormality
when someone is unable to cope with ordinary demands of day to day living
examples of signs someone is not functioning adequately
- unable to maintain basic hygiene and nutrition
- unable to hold down jobs
- unable to maintain social relationships
What are signs someone is failing to function adequately according to Rosenham and Seligman
Rosenham said these signs are
- not carrying out typical interpersonal interactions (e.g. eye contact, personal space)
- severe personal distress
- their behaviour becomes irrational and dangerous to themselves or others
example of how failure to function adequately can result in diagnosis
- used in combination with statistical infrequency
- can identify if the bottom 2% of people on IQ distribution curve are failing to function adequately, and then can diagnose them with intellectual disability
Describe deviation from ideal mental health as a definition of abnormality and who suggested it
when someone doesn’t meet the set of criteria for a good mental health
Jahoda
Examples of Jahodas ideal mental health criteria
- no symptoms of distress
- rational, and accurate with self perception
- trying to reach self-actualisation
- cope with stress
- realistic view of the world
- good self esteem and lack of guilt
- independent of others
- can work, love and enjoy leisure
- in stable social relationships
What is the DSM 5
(diagnostic and statistical manual of mental disorders)
-that classify symptoms for different mental disorders so patients can be accurately diagnosed
Define a phobia
an irrational fear of an object or situation that creates excessive fear and anxiety
-triggered by an object, place or situation
3 categories of phobias
- specific - an object or a situation
- social phobia (non specific) - of social situations (involving people)
- agoraphobia (non specific) - fear of going outside or in public place (where escape or getting help may be difficult if things go wrong)
Behavioural characteristics of phobias
- Panic - involves crying and running away (for kids- freezing)
- Avoidance - avoid coming into contact with phobic stimulus
- Endurance - remain in phobic stimulus presence
Emotional characteristics of Phobias
- Unreasonable emotional response - anxiety and fear are disproportionate to threat
- Fear - immediate and short term extremely unpleasant response
- Anxiety - an unpleasant state of high arousal (longer term)
Cognitive characteristics of phobias
- Selective attention to phobic stimulus - hard to look away from the phobic stimulus when present
- Irrational beliefs - beliefs in relation to phobic stimulus are inaccurate and actually real
- Cognitive distortions - perception of phobic stimulus is unrealistic and inaccurate
behavioural explanation to how phobias are acquired and maintained
What’s the model called?
who coined it
THE TWO PROCESS MODEL
- acquired by classical -associate something we have no fear of with something that we have fear of
- maintained by operant conditioning
(Mowrer)
describe the study showing acquisition of a phobia through classical conditioning
Little Albert (9 month old baby)
- had no unusual anxiety to a white rat at start
- whenever rat was presented, iron bar was hit, creating loud frightening noise
- when the neutral stimulus of a white rat was paired with the unconditioned stimulus of a loud noise, the unconditioned response of fear from the loud noise, was gradually associated with the neutral stimulus of a white rat
- now the white rat (conditioned stimulus) produces a conditioned response of fear and anxiety
- this was generalised to anxiety reactions from similar furry objects (non white rabbit, Santa claus beard, fur coat)
describe how phobias are maintained
by operant conditioning
- when our behaviour is reinforced (reward or punishment)
- reinforcement increased frequency of behaviour
- when you avoid an unpleasant situation (negative reinforcement) and as a result get a desirable consequence of not being in presence of phobic stimulus (escape fear and anxiety), the behaviour will be repeated
