Document Summary
Refers to an enduring change in the way an organism responds based on its experience. Drug effects (caffeine-induced jitters are not learning) Our experiments can uncover the laws of learning. These laws will apply to animals and humans. The russian physiologist pavlov noted that re exive salivation in dogs could be elicited by stimuli associated with feeding. Re ex: response that is reliably elicited by a stimulus. Neutral stimulus is feared to as the conditioned stimulus (cs); not re exive. Ucs is a re exive response that was not conditioned because it was engrained already. Cs is paired with the ucs over many trials. Eventually comes to elicit a conditioned response (cr: resembles the ucr) Extinction: refers to the weakening of conditioning evident when the cs is presented repeatedly without the ucs. Spontaneous recovery: refers to the reemergence of a previously extinguished cr.
