Document Summary
Learning: relatively permanent change in behavior due to experience once you learn something its dif cult to unlearn it. 2 events occur together conditioning: process of learning associations. Classical: 2 stimuli lightning signals thunder: operant: consequences action a effects action b. Ivan pavlov (1849-1936) association of two stimuli begins with a re ex pair a neutral stimulus with the stimulus that evokes that re ex neutral stimulus will soon evoke the re ex on its own. Unconditioned stimulus: automatically triggers a response (ucs) loud noise. Conditioned stimulus: previously neutral stimulus that comes to trigger a response (cs) ice hitting the glass before dinner. Conditioned response: learned response to a previously neutral conditioned response (cr) running downstairs for dinner. Acquisition: the initial stage of learning, during which a response is established the phase in which a stimulus comes to evoke a cr. Extinction: when a ucs does not follow a cs the cr is diminished.
