9 Unconditioned Stimulus (UCS): a stimulus that naturally and automatically triggers a response. Unconditional Response (UCR): the unlearned, naturally occurring response to the UCS.
10 Conditioned Stimulus (CS): an originally irrelevant stimulus that, after association with the UCS, comes to trigger a response.Conditioned Response (CR): the learned response to a previously neutral stimulus.
12 Classical Conditioning TRICKY FACT: We know learning exists because the CS is linked to the UCS.This is called ACQUISITION.Acquisition does not last forever.The moment the CS is no longer associated with the UCS, we have EXTINCTION.
18 Pavlov spent the rest of his life outlining his ideas Pavlov spent the rest of his life outlining his ideas. He came up with 5 critical terms that together make up classical conditioning.AcquisitionExtinctionSpontaneous RecoveryGeneralizationDiscrimination
19 Spontaneous RecoveryThe reappearance, after a rest period, of an extinguished conditioned response.
20 Generalization and Discrimination Something is so similar to the CS that you get a CR.Something so different to the CS so you do not get a CR.
