A type of learning in which we develop responses to certain stimuli that are not naturally occurring.

A type of learning in which a subject comes to respond to a neutral stimulus as he would to another stimulus by learning to associate the two stimuli. It can also be called respondent conditioning or Pavlovian conditioning.

The procedure in which an initially neutral stimulus (the conditioned stimulus, or CS) is paired with an unconditioned stimulus (or US). The result is that the conditioned stimulus begins to elicit a conditioned response (CR). Classical conditioning is nowadays considered important as both a behavioral phenomenon and as a method to study simple associative learning. Same as Pavlovian conditioning. Describes stimulus-stimulus associative learning.
