Occasion setting by drug states: Functional equivalence following similar training history.
Three experiments examined whether a drug state serving as a positive feature for pairings between a discrete conditional stimulus (CS, 15-s light or 15-s noise) and sucrose could transfer facilitative control to a CS with which it had never been presented. To do so, a CS was paired with a sucrose reward in the nicotine (0.4 mg/kg), amphetamine (AMP, 1mg/kg), or chlordiazepoxide (CDP, 5mg/kg) d...
متن کاملOccasion-setting training renders stimuli more similar: acquired equivalence between the targets of feature-positive discriminations.
In two experiments rats received training on two concurrent appetitive feature-positive discriminations. A preliminary test in Experiment 1 confirmed previous demonstrations of the transfer of occasion-setting properties--the feature from one of these discriminations was better able to facilitate responding to the occasion-set target CS from the second discrimination than to a control stimulus ...
متن کاملOccasion setting and drug tolerance.
There is considerable evidence that drug-paired cues become associated with drug effects. It has been hypothesized that these cues act as Pavlovian conditional stimuli (CSs), and elicit conditional compensatory responses that contribute to tolerance. On the basis of a conditioning analysis of tolerance, we would expect that it should be possible to establish drug-paired cues as occasion setters...
متن کاملOccasion Setting without Feature-Positive Discrimination Training
In four experiments rats received training in which a brief conditioned stimulus, x, occurred during presentations of an extended feature stimulus, A; a second brief stimulus, y, occurred during presentations of a second feature, B. In Experiment 1 both x and y were paired with food and, in a subsequent test, they elicited more conditioned responding when they were presented in the feature with...
متن کاملOccasion setting of timing behavior.
Rats were trained on a temporal switching discrimination, with 2 features, A and B, signaling 2 target conditioned stimuli, x and y; feature offset and target onset were separated by a 5-s feature-target interval, and all target stimulus presentations terminated in a food pellet. The target conditioned stimuli were either short or long (6 or 30 s): Specifically, when signaled by A, x was 6 s an...
