WebClassical conditioning involves learning the relations between stimuli. In its simplest form, a neutral stimulus precedes a stimulus (the unconditioned stimulus, or US) that elicits a response (the unconditioned response, or UR). Learning is indexed by the development of a response (the conditioned response, or CR) to the neutral stimulus ...
