PSYC 356 Lecture Notes - Lecture 7: Asymptote, Devaluation, Conditioned Taste Aversion
Document Summary
Training in food restricted rats: cs: tone us: food, response: foraging behaviors. Devaluation: group1: remained food restricted (like the control group, group2: fed (devalue us) so they are not motivated to eat. Results: group 1 responded robustly to cs, group 2 responding was weak. Conclusions: the memory of the us remains integral in the expression off the cr (s- If s-r learning was happening, devaluing the us would do nothing to the way the rats respond to the cs. Since the us is clearly still important, we know this is s-s learning. A new burrito place stays open until 2am. The blocking effect: prior conditioning of a cs1 (a) interferes with or blocks the development of cs2 (b) Control group will eat fewer burritos than the experimental group because an association between the hangover and burrito has occurred (since there was no prior exposure to the hangover). 2 events occurring together will become associated.
