Rescorla's cognitive theory proposed that the real reason Pavlov's dogs salivated to conditioned stimuli was that these stimuli allowed them to predict what food would come.
Explanation:
Pavlovian theory explains that the stimulus is related with the conditioned response. To prove this Ivan Pavlov conducted some experiments regarding stimulus with his dogs. In this experiment he found that the objects or events are capable of triggering the conditioned response. A bell is used as a neutral stimulus in the experiment designed by Pavlov.
The change that occurs in the associative strength between the conditioned stimulus and unconditioned stimulus is well explained by Rescorla’s theory.
The dog under experiment is presented with stimulus and food, and this process is repeated for several numbers of times. Finally the dogs started to salivate in response to the stimulus.
