Thus, if a rat spends many months performing the lever-pressing behavior turning such behavior into a habiteven when sucrose is again paired with illness, the rat will continue to press that lever see Holland, Modern studies of classical conditioning use a very wide range of CSs and USs and measure a wide range of conditioned responses.
This is called spontaneous recovery : following a lapse in exposure to the CS after extinction has occurred, sometimes re-exposure to the CS e.
Somewhat counterintuitively, though, studies show that pairing a CS and a US together is not sufficient for an association to be learned between them. Or maybe, thinking back on a new restaurant you tried recently, you realize you chose it because its commercials play happy music classical conditioning.
But it is far more than just a theory of learning; it is also arguably a theory of identity. Discussion Questions Describe three examples of Pavlovian classical conditioning that you have seen in your own behavior, or that of your friends or family, in the past few days.
The reason? For example, if a pigeon learns that pecking one light will reward two food pellets, whereas the other light only rewards one, the pigeon will only peck the first light. The child demonstrated stimulus generalization by also exhibiting fear in response to other fuzzy white objects including stuffed toys and Watson own hair.
It seems that a continuous schedule, when every response is reinforced, is good for learning new responses, but a partial schedule would be better at maintaining the behaviour and avoiding extinction.
These are natural reinforcers, which result in a strengthening of the behaviours leading to them. However, after multiple pairings of the bell with the presentation of food, the dog starts to drool at the sound of the bell.
