Psychopathology Flashcards
What is meant by deviation from social norms?
- Behaviour goes against expectations of a community or culture, or what most people do
- Social judgements about what’s acceptable
What is an example of deviation from social norms?
Drinking alcohol at breakfast
What is a positive of deviation from social norms?
+ RLA = disorders can be assessed and diagnosed
What are the negatives of deviation from social norms?
- Reductionist = doesn’t consider factors such as distress
- Cultural relativism = what’s normal in one culture, may be abnormal in another
What is meant by deviation from ideal mental health?
- Jahoda produced a criteria for a good mental health -> self attitude, self actualisation, resistance to stress, autonomy and perception of reality
What is an example of deviation from ideal mental health?
Negative self worth and not being able to deal with stress
What is a positive of ideal mental health?
+ Comprehensive definition = includes all reasons why someone may seek help
What are the negatives of ideal mental health?a
- Cultural relativism = self-actualisation specific to Western countries
- Unrealistically high standards = few people achieve most ideas
What is meant by the failure to function adequately?
- Rosenhan and Seligman proposed signs of failing to cope with the demands of everyday life = include personal distress, unpredictability and irrationality
What is an example of failure to function adequately?
Washing hands religiously
What are positives of failure to function adequately?
- Can help to explain mental disorders
- Recognises individuals’ perspectives
What are negatives of failure to function adequately?
- Based on subjective judgements by psychiatrists
- Difficult to distinguish from deviation from social norms - extreme sports could be both
What is meant by deviation from statistical norms?
- Numerically unusual behaviour of characteristic
- Extreme ends of normal distribution curve
What is an example of deviation from statistical norms?
IQ, Height, Weight
What is the positive of deviation from statistical norms?
- Objective and simple to access
What are the negatives of deviation from statistical norms?
- Unusual characteristics can be positive (e.g very high intelligence)
- Ignores individual differences
What are the 4 definitions of abnormality?
- Deviation from social norms
- Deviation from ideal mental health
- failure to function adequately
- Deviation from statistical norms
What are the behavioural characteristics of phobias?
- Panic = crying, screaming etc
- Avoidance = difficult to go about daily life
- Endurance = remaining in presence of phobia causes increased anxiety
What are the emotional characteristics of phobias?
- Fear = immediate response, occurs when thinking about phobia
- Anxiety = unpleasant state of high arousal which makes it difficult to be positive
- Unreasonable responses = response to phobia disproportionate to danger of stimulus
What are the cognitive characteristics of phobias?
- Selective attention = hard to look away from stimulus
- Irrational beliefs = beliefs that are impossible in reality - E.g social phobias
- Cognitive distortions = phobic stimulus likely to be different to people without a phobia
What is the explanation for phobias?
The Two-Process model
Who created the two-process model?
Mowrer (1960)
What is the two-process model based upon?
Classical conditioning and operant conditioning
How does classical conditioning work within the two-process model?
Acquisition by CC: learning to associate a neutral stimulus (not afraid of) with an unconditioned stimulus (already triggers a fear response)
What is an example of classical conditioning explaining phobias?
- Watson and Raines (1920)
- Little Albert Study
NS (rat) = no fear
UCS (loud noise) = UCR (fear)
NS (rat) + UCS (loud noise) = fear
CS (rat) = fear
How does operant conditioning work within the two-process model?
Maintenance of OC: reinforces behaviour characteristics of phobia
- Responses acquired (usually tend to decline over time, so phobias must be maintained)
- Negative reinforcement (avoiding unpleasant situations) leads to desirable consequences (no fear or anxiety), meaning the behaviour is likely to be repeated and so the phobia is maintained
What is an example of the two-process model?
- A person who’s terrified of spiders is likely to run away when they see one
- Escaping the fear acts as a positive reinforcer - increases the likelihood of avoiding spiders in the future (phobia maintained)
- Positive consequence = behaviour likely to be repeated
What are the 2 treatments for phobias?
Flooding and Systematic Desensitation
What is flooding?
Immediate exposure to a very frightening situation
How long does flooding last?
Lasts around 2-3 hours (longer than SD) - sometimes only 1 session is needed to cure a phobia
How does flooding stop phobic responses very quickly?
- Because patients are unable to avoid the phobic stimulus, so they quickly learn that it is harmless
- This process is called extinction – where the CS is encountered without the UCS, resulting in the CS no longer producing the CR
- Patient may achieve relaxation in the presence of the phobic stimulus because they become exhausted by their fear response
What is Systematic Desensitisation?
Reduces phobia through classical conditioning
What are the 3 processes within Systematic Desensitisation?
- Anxiety Hierarchy
- Relaxation
- Exposure
What happens within the Anxiety hierarchy in SD?
Patient and therapist work together to create a list of situation related to phobic stimulus which provokes anxiety - ordered from least to most frightening
What happens within the relaxation concept in SD?
Therapist teaches patients relaxation techniques - drugs like ‘valium’ can be used to relax patients
What happens within the Exposure concept in SD?
Patient is exposed to phobic stimuli in a relaxed state
- Vitro = client imagines exposure
- Vivo = Client is exposed
How long does Systematic Desensitisation last?
It takes place over several sessions, starting at the bottom of the hierarchy to the top = treatment is successful when they can stay relaxed in situations high on the hierarchy
What are the positives of the phobia explanations?
- Research support = The Little Albert case study shows that phobias can be learnt so therefore, Mowrer’s two-process model has validity
- RLA = The two-process model explains why patients need to be exposed to a feared stimulus which has led to the development of treatments, such as flooding and systematic desensitisation
What are the negatives of phobia explanations?
- Incomplete explanation = some phobias exist without an initial traumatising experience so invalidates the two-process model
- The model is reductionist = two-process model does not consider all perspectives so the role of cognition and biology have been ignored in this explanation
