Renewal after overexpectation.
Four magazine approach experiments were performed with rats to explore the decrement produced by reinforcing a compound of two previously conditioned stimuli. Compound presentation produced the usual over-expectation decrement in responding to the individual stimuli. However, testing in an alternative, but similarly treated, context allowed renewal of the initial responding to the individual st...
متن کاملThe effects of FG7142 on overexpectation of Pavlovian fear conditioning.
Six experiments studied the role of GABA-sub(A) receptor activation in expression of overexpectation of Pavlovian fear conditioning. After separate pairings of CSA and CSB with shock in Stage I, rats received pairings of the compound AB with shock in Stage II, producing overexpectation of fear. The expression of overexpectation was attenuated, in a dose-dependent manner, by the benzodiazepine p...
متن کاملTraditional Perceptrons Do Not Produce the Overexpectation Effect
Perceptrons are typically viewed as being an artificial neural network that embodies the Rescorla-Wagner model of learning. One of the important properties of the Rescorla-Wagner model was its prediction of the overexpectation effect. However, we show below that a typical perceptron is not capable of generating this effect. This result brings into question assumed relationships between artifici...
متن کاملRenewal after the punishment of free operant behavior.
Three experiments examined the role of context in punishment learning. In Experiment 1, rats were trained to lever press for food in Context A and then punished for responding in Context B (by presenting response-contingent footshock). Punishment led to complete suppression of the response. However, when responding was tested (in extinction) in Contexts A and B, a strong renewal of responding o...
متن کاملRenewal after the extinction of free operant behavior.
Four experiments were performed to explore the role of context in operant extinction. In all experiments, leverpressing in rats was first reinforced with food pellets on a variable interval 30-s schedule, then extinguished, and finally tested in the same and a different physical context. The experiments demonstrated a clear ABA renewal effect, a recovery of extinguished responding when conditio...
