DSM criteria of phobias
- unreasonable, excessive fear out of proportion to actual danger
- phobic stimulus always produces immediate fear/anxiety
- fear or avoidance is persistent for 6 months+
- phobia stimulus is actively avoided or endured with intense fear
- fear causes clinical distress
- not better explained by another disorder
according to the behavioural approach, how do phobias develop?
- phobic stimulus is paired with a frightening/painful event
- phobias are acquired through classical conditioning
- phobias are maintained via operant conditioning
Little Albert case study
- Albert is presented with a rat (CS) and various other animals = no fear
- Albert is presented with a surprising loud noise (US) = fear (UR)
- Albert presented with rat this time paired with loud noise = fear
- Albert presented with rat = fear (CR)
conditioned stimulus
previously a neutral stimulus that acquires a response by being paired with a US
conditioned response
response evoked by CS
unconditioned stimulus
biologically significant event
unconditioned response
response evoked by US
generalisation
when stimuli similar to the phobic stimulus also produces a fear response
for example, little Albert generalised hid fear of rats and was also afraid of Santas beard and rabbits
