Basic principles o acquisition in classical conditioning: neutral stimulus needs to come before the unconditioned stimulus, the time btwn the 2 stimulu should be close (about half a second to. 5 sec. apart is ideal: pairing needs to occur several times, often many, the conditioned stimulus needs to be distinctive or stands out from other competing stimuli. Extinction and spontaneous recovery: extinction, respondent extinction: when us does not follow a cs, a cr starts to decrease and at some point completely diminishes, spontaneous recovery, after a rest period an extinguished cr spontaneously recovers. How does classical conditioning work: stimulus substitution (pavlov, cognitive perspective (rescorla) Applications of classical conditioning: evaluative conditioning: changes in the liking of a stimulus that result from pairing that stimulus with other positive or negative stimuli.
