Psychopathology - Behavioural approach - expalanations Flashcards
What is the two process model?
Phobias are acquired because of classical conditioning and maintained through operant conditioning.
What is Classical conditioning?
Classical Conditioning states that phobias are learnt through the process of association, when a person associates a negative experience with a harmless event.
UCS
unconditioned stimulus - usually the negative experience
NS
neutral stimulus - usually the phobic stimulus
CS
conditioned stimulus - usually the phobic stimulus
UCR
unconditioned response - fear
CR
conditioned response - fear
explain how phobias are maintained
operant conditioning suggests that phobias are maintained through negative reinforcement. when an indvidual avoids the phobic stimulus the avoidance behaviour becomes a negative reinforcer. as aoiding the phobic stimulus helps get rid of the fear response making you feel relaxed. this means the avoidance phobia is strengthened and thus the phobia is maintained.
The Little Albert Experiment - watson an rayner
this experiment suggests that phobias can be acquired through classical conditioning. at first a 11 month boy had no fear of white rats (NS). However When the rat (NS) was paired with a loud noise (UCS), this produced a fear response (UCR). through several repetitions , Albert made the assumption between the white rat (CS) and the fear response(CR).
evaluation of two process model - strengths (3)
- can explain how phobias are developed
- Little Albert experiment provides supporting research methods
- effective treatments based on behavioral approach.
explain the strength - can explain how phobias are developed
it can explain how people can recall a specific event that led to them developing a phobia.
- E.g sue et al (1994) found that agoraphobics are most likely to explain their phobia in terms of a specific event which suggests that classical conditioning can be involved in the development of phobias.
explain the strength - Little Albert experiment
This experiment carried out by Watson and Rayner (1920) provides supporting research evidence for the behavioral approach.
- explain the little Albert experiment.. end explanation with this study suggests that phobias can be learnt through classical conditioning.
explain the strength - effective treatments based on behavioral approach.
- behaviorist ideas have been used to develop effective treatments such as systematic desentisation and flooding in addressing phobic symptoms.
- e..g systematic desentisation helps people unlearn their fear response , using principles of classical conditioning while flooding prevents people avoiding phobias and stops negative reinforcement from taking place.
-the fact that therapy based on the behaviorist approach is effective in dealing with phobic systems provides support for the validity of the behaviorist explanation as to how phobias are acquired and maintained.
evaluation of two process model - weaknesses (3)
- traumatic experience missing
- cannot explain all types of psychological disorders.
- ignores cognitive aspects
explain the weakness - traumatic experience missing
A limitation of the two process model is that a phobia does not always develop after a traumatic incident.
- e.g Davies (1992) found that only 7% of people with a fear of spiders (arachnophobia) recalled having a traumatic incident with a spider which suggests not everyone has a negative experience which develops into a phobia.
- reduces the validity of the behavioral approach because it only offers a partial explanation as conditioning alone cannot explain phobia.
