core theory - behaviourism

- behaviourists assume we learn from our enviroment.

classical conditioning - we learn through association.

pavlovs dogs - unconditional stimulus leads to an unconditioned response; conditional stimulus eventually leads to a conditional response.

operant conditioning - fear through negative reinforcement/punishment.

social learning theory - we learn through observing others.

evaluation of the core theory

- ignore the thinking behind phobias.

- assumes you need direct experience with something to be afraid of it and you dont, indirect is also very powerful.

core study - little albert

- an 11 month old infant was studied and watson and rayner tested on him to see if he was afraid of animals and objects. he wasnt.

- they then paired the presentation of white rat with hitting a steel bar behind alberts head, until he cried.

- many pairing led to albert to see the rat to cry and then fear it (without the noise from the bar).

criticisms

- it was unethical

- it was small and a biased sample

- it lacks ecological validity.

alternative theory - evolutionary approach

- assumptions (every behaviour we display we do because of survival).

- it is vital for us to be afraid of certain things, e.g. spiders in certain parts of the world are deadly.

- we inherit such phobias, they are instictual.

- we are born with a biological preparedness to be afraid of certain that jeopardise our survival.

- treating phobias that do not pose a risk to our survival are the most difficult to cure.
