PSYC 352 Lecture Notes - Lecture 10: Classical Conditioning, Opponent Process
Document Summary
After conditioning occurs, presenting us at different intensity alters the strength of the cr in response. S-r model: stimulus (ns) becomes associated with the unconditioned response. S-s model: ns becomes directly associated with the us. Cs acts as a substitute for the us. The cr prepares the organism for presentation of the us. The cr counteracts the effects of the ur.

Ex- lowers heart rate before taking an upper (cocaine) If the drug is not taken there is potential health risk or less serious withdrawal symptoms. If have extinguished cr & take same high dose of drug, more likely to overdose. Proposed a mathematical way to calculate the change in strength of the cs"s relationship to the.
