Interrater reliability: comparing the results of measurements and seeing if they give
consistent and similar scores.


Evaluation:

There is supporting evidence for the interrater reliability of diagnosing phobias. Evidence

to assess 54 patient interviews obtained…

Behavioural Theories:

Phobias are acquired three ways:
Classical Conditioning
Operant Conditioning
Social Learning Theory

Classical Conditioning:
Fears are acquired when an individual associates a neutral stimulus with a fear response.
e.g. Little Albert:
Watson and Rayner (1920) used an 11 year old boy.
UCS (loud noise) provokes the UCR (fear).…

Biological Therapies

Chemotherapy

For there to be a biological cause for phobias, there must be a biological cause.
Drugs can help reduce the high levels of anxiety and be used with psychological therapies to
deal with the psychological causes of their phobia.

Betablockers:
