Psychopathology - Behavioural Approach to Explaining Phobias Flashcards
the behavioural approach emphasises the
role of learning in the acquisiition of behaviour
the behavioural approach focuses on
behaviour - what we can see
what are the 3 key behavioural aspects of phobias
panic
avoidance
endurance
what did mowrer 1960 propose
the 2 process model
based on teh behavioural approach to phobias
what does the the 2 proces model of the behavioural approach to phobias state
phobias are acquired by classical conditioning and then continue because of operant conditioning
ACQUISITION BY CLASSICAL CONDITIONING - explain what classical conditioning involves
learning to associate something of whihc we initially have no fear (neutral stimulus) with something that already triggers a fear response (unconditioned stimulus)
Watson and Rayner created a phobia in
9 month old Little albert
t/f at the start of the study albert showed no unsual anxiety
and he tried to play with the white rat when shown it
T
How did the researchers set out togive albert a phobia
whenever rat was presented to albert
researchers made a loud, frightening noise by banging an iron bar close to alberts ear
what was the ucs in the little albert study
noise
the noise is the ucs whihc created a
unconditioned response
the noise is the ucs whihc created a
unconditioned response of fear
the rat was a
neutral stimulus
when the rat (ns) and the UCS are encountered close together over time what happens
NS becomes associated with the UCS
and both now produce the fear repsonse
albert displayed fear when he saw a
rat (ns )
albert now displayed fear when he saw the rat (ns) identify what the conditioned stimulus and conditioned repsonse are now
rat is conditioned/learned stimulus
and it produces a conditioned response of fear
conditioning is then generalised to
similar objects
from the little albert study how do we know conditioning is generalised to otehr similar objects
they tested albert by showing him other furry objects
e.g non white rabbit ,fur coat
albert showed distress at the sight of all of these
from 20 onwards is realted to maintainence by operant condiitoning
all from 6-18 is related to acquisition by classical conditiong
repsonses acquired by CC tend to
decline over time
responses acquired by cc tend to decline over time but phobias are often
long lasting
phobias are often lonf lasting which is due to
operant conditioning
when does operant conditioning take place
when behaviour is reinforced (rewarded) or punished
what doe reinforcement tend to increase
the frequency of a behaviour
t/f negatove and positive reinforcemtn both increase frequency of a behaviour
t
explain how negative reinforcement works
indi avoids situation hwihc is unpleasant
this behaviour results ina desirable consequence
which means behaviour will be repeated
mowrer suggested that whenever we avoid a phobic stimulus ..
we succesfully escape the fear and anxiety that we would have experienced if we had remained there
reductino in fear reinforces the avoidanec behaviour and so the phobia is maintianed
EVAL- strength real world application to therapy
whats the strngth
whta have behaviourist ideas been sed to develop
what do the developmetns do
consequently since therapies succesful how does htis strenghten approa
strength : application to therapy
the behaviourist ideas have been used to develop treatments e.g systematic desensitisation flooding
SD helps people unlearn fears using prinicples of cc , flooding stops people avoiding phobes and stops negatve reinforcement taking place
consequently these therapies succesfully used to treat people w phobias gigiving more support for effectiveness of behaviourtist explanantion
EVAL - weakness bio preparedness
what may it not provide full expl of
bouton highlighted
evo psych suggested
what is it called and what does it cast on 2 process model
may not provide full explanation of phobias
bounton highlighted evoluntionary factros could paly role esp if avidance of a particular stimulus (snakes) increased chance of survival for ancestors
consequently evo psychs suggest we predisposed to some phobias e.g snakes as theyre innate than learnt as such phobias acted as survoval mechanims for ancestors
this is called biological preparedness and casts doubt on 2 porcess model snce sugeests theres more to phbias than learning
EVAL - strneght phobias and trauma xp
what is there evidence for
what does lil albert show
what did they find in systematic evidence group compared to ctrl group
this confirsm
evidence for lnk between phobias and bad xp
little albert shows how a frightening xp involving stimulus cna lead to phobia of stimmy
more systematic evidence found 73% people with fear of dentla treatment expereinced traunmatic xp mostly involving dentistry - other xp violetn crime
copmared to ctrl grp of people with low dental anxiety where only 21% experieenced a truamtic event
confirm association between stimul( dentistry) and UCR (pain) does lead to development of phobia
