When a person avoids a feared stimulus the negative feelings of fear are removed so behaviour is reinforced through negative reinforcement

Q

Supporting evidence for the idea that phobias are acquired through classical conditioning

A

-Watson and Raynor-at first the white rat was a neutral stimulus then a loud bang was sounded behind him and he learned to associate the loud bang with the white rat which elicited a fear response

14
Q

what is a problem with watson and raynors study

A

-lack ecological validity-not true to how we aquire phobias in real life
-case study so is idiograpahic so cannot generalise to wider population

Q

Supporting evidence for the idea that phobias are acquired through classical conditioning and maintained by operant conditioning

A

Di Gallo-reported that around 20% of people experiencing a traumatic car accident developed a phobia of travelling in cars (classical conditoning)
they also tended to make avoidance responses which involved staying at home (operant conditoning as avoidance causes relief)

16
Q

does Di Gallos evidence raise any limitations

A

80% didnt develop a phobia showing its not a complete explanation and that there should be other factors

17
Q

Limitation for behaviourist explanation of phobias

A

-not all phobias are caused by traumatic events
-could be genetically determined eg-diathesis stress model which suggest we have a genetic vulnerability for developing mental disorders that will only be triggered by certain events

18
Q

what is the 2 alternative explanations for the development of phobias

A

-biological-we tend to show feat of snakes as this would’ve been adaptative previously so this has been passed down through evolution
-cognitive-phobias could be acquired through irrational negative beliefs

19
Q

what are the 2 treatments for phobias

A

-flooding
-systematic desensitisation

20
Q

what is systematic desensitisation

A
  1. Fear hierarchy- doctor and patient create a fear hierarchy which ranks from least to most feared stimulus
  2. Patient is taught relaxation techniques that encourage slow breathing and muscle relaxation
  3. the patient is then exposed to there phobic situation. They are encourage to keep calm as two emotional states cannot exist at the same time (reciprocal inhibition)
21
Q

what does in vitro mean

A

when the client imagines exposure to the phobic situation

22
Q

what does in vivo mean

A

the client is exposed to the phobic situation

23
Q

what are 2 pieces of supporting evidence for systematic desensitisation

A

-ost
-Klosko

24
Q

what did ost find

A

90% much improved or completely recovered 4 years later showing systematic desensitisation is effective for a longtime after treatment

25
Q

what did klosko find

A

found that systematic desensitisation was better than drug treatment
87% where free of panic after systematic desensitisation compared to 50% for those treated with drugs

26
Q

why may it be prerable to treat someone with systematic desensitisation rather than drug treatment

A

drugs have side effects

27
Q

what doesn’t systematic desensitisation take into account

A

doesnt take into account evolutonary relationships
-is not effective in treating phobias that werent acquired through classical conditioning

28
Q

what are some positives of systematic desensitisation

A

-exposes patient to the feared stimulus gradually creating less distress
-more ethical then flooding

29
Q

what are some negatives of systematic desensitisation

A

-less effective at treating social phobias and agoraphobias where cognitive factors are also important
(CBT may be more effective in this situation)

30
Q

what is flooding

A

exposing the patient to there phobia in one go and encouraging them to stay near there phobia until the anxiety has worn off

31
Q

Supporting evidence for flooding

A

-Kaplan and Tolin
-Wolpe

32
Q

what did Kaplan and Tolin find

A

-Kaplan and Tolin-65% of patients had no symptoms of a specific phobia 4 years later showing flooding is effective for a longtime after treatment

33
Q

what did Wolpe find

A

-Wolpe-used flooding to remove a girls phobia of being in cars. The girl was driven around for 4 hours until her hysteria had eradicated

34
Q

what are 3 negatives of flooding

A

-doesn’t always work and can strengthen the association between the conditioned and unconditioned stimulus should something go wrong
