pavlov

Question 1

what was the aim of pavlov

Answer 1

explain role of conditioned reflexes in eating behaviour of dogs, how salivation is produced as a result of 2 unrelated stimuli being associated

Question 2

what was the method of pavlov

Answer 2

soundproof lab
collected saliva by number of drops produced
metronome paired with food 20x
forward conditioning (NS before UCS)
backwards conditioning (NS after UCS)
tested extinction, stimulus generalisation and spontaneous recovery

Question 3

what were the results of pavlov

Answer 3

NS=no response, UCS = salivation
forward = salivation after 9 seconds
backwards = no salivation
extinction found as volume declined
spontaneous recovery some time
stimulus generalised found using similar tone

Question 4

what conclusions were made

Answer 4

conditioning leads to a conditioned response

Question 5

evaluate pavlov

Answer 5

+ objective and scientific, isolated dog, controls over EV
+ repeated on many dogs to test reliability
- unable to measure brain activity so assumed it happened in cerebral cortex, conclusions not cmletely accurate
- ideas on evolution lead pavlov to generalise, many differences
