PS102 Lecture Notes - Lecture 2: Drug Tolerance, Conditioned Taste Aversion, Reinforcement
Document Summary
Compensatory drug effects are your body responding to drugs to counteract them. Morphine injection and train sounds (neutral stimulus) person feels bad from homeostasis. Train alone (conditioned stimulus) person feels bad from homeostasis. The train sounds, by eliciting the opposite physical effect, the body now requires more morphine. Before the classical conditioning begins: ucs (say a partner) ucr (desire) During: pair partner with a ns (kinky boots) ucr (desire) Additional processes in classical conditioning: acquiring the cr depends on pairing of a ucs and the ns. They must have stimulus contiguity and happen together in time and space. These must be novel and intense to have the strongest association: extinction (gradual weakening, disappearance of cr) + friends house (ns) cs ucr (fear) Friends house (cs) fear (cr: spontaneous recovery (reappearance of extinguished response after a period of nonexposure) Renewal effect (reappearance of response if extinguished in a different environment)
