PHARMAC. BIOCHEM. BEHAV. 7(5)- Rats were trained to run in a straight alley under conditions of partial or continuous reinforcement. Extinction was slower after partial reinforcement. Chlordiazepoxide, administered during acquisition only, had no effect on acquisition but abolished the partial reinforcement extinction by: 9.

The partial reinforcement extinction effect after treatment with chlordiazepoxide. Feldon J, Gray JA. Two experiments are reported, in which rats were run in a straight alley for food reward with or without injections of the anti-anxiety drug, chlordiazepoxide (CDP).

Pharmacol Biochem Behav – Google Scholar Ziff DR, Capaldi EJ () Amytal and the small trial partial reinforcement effect: Stimulus properties of early trial by: They were tested in the straight alley with food reward on either continuous (CRF) or partial (PRF) reinforcement at one trial a day and were injected with either 5 mg/kg chlordiazepoxide HCl (CDP) or with saline before the daily trial throughout acquisition and extinction.

The effects of the drug on resistance to extinction interacted with those of the LS lesion in ways which were consistent with the hypothesis that CDP Cited by: The partial reinforcement extinction effect: influence of chlordiazepoxide in septal lesioned rats.

Feldon J, Gray JA. Rats sustained electrolytic lesions either in the medial septal (MS) or lateral septal (LS) area or they were by: The partial reinforcement extinction effect (PREE) was analyzed in humans using a quasi-multiple schedule of reinforcement with two discrete trial tasks.

The first task was a videogame analog of a shuttle box. Using a joystick, subjects were required to move a cue in one of four directions for rein. This study describes the relationship between the tranquilizing drug chlordiazepoxide HCL and different magnitudes of reward during acquisition and extinction of a partially reinforced runway response.

The results do not support predictions drawn directly from Amsel’s (, ) frustrative nonreward hypothesis. Animals exhibited the same magnitude of reward extinction effect whether Cited by: 5.

The PREE is defined as an increased resistance to extinction that is observed after training with partial reinforcement as compared to continuous reinforcement. This paradoxical learning effect constitutes an experimental example of response-outcome uncertainty during acquisition that results in an increased, rather than in a decreased, behavioural persistence during extinction Cited by:   Two experimental procedures were employed to establish the reason why hippocampal lesions apparently block the development of tolerance for aversive events in partial reinforcement experiments, but do not do so in partial punishment experiments.

Intracerebroventricular chlordiazepoxide and the partial reinforcement extinction effect. Author: McCullough, Trevor. ISNI: X Awarding Body: University of Ulster Current Institution: Ulster University Date of Award: The behavioral data indicated that subjects exposed to partial reinforcement were more persistent than subjects exposed to continuous reinforcement.

Significant increases in skin conductance were observed at the start of acquisition and extinction, but there were no differences between the two reinforcement Cited by: 4. The PREE was abolished when amphetamine was administered throughout the acquisition trials or on nonrewarded trials, irrespective of drug treatment on rewarded trials.

Paradoxical Effects: Partial Reinforcement Extinction Effect Frustration theory A theory of partial reinforcement extinction effect, according to which extinction is retarded after partial reinforcement because the instrumental response becomes conditioned to to the anticipation of frustrative non-reward.

Under vehicle injections, extinction and re-extinction curves were indistinguishable, but drug treatments showed that there was less resistance to extinction in the re-extinction phase. Chlordiazepoxide facilitated extinction and re-extinction, with an earlier effect during by: 3.

Effects on the extinction of GABAergic drug, chlordiazepoxide (CDP), and glutamatergic drug, D: cycloserine (DCS), in C57BL/6 mice were compared. Following a palatability test (Experiment 1), Experiments involved food-reinforced lever press training followed by extinction sessions at 1.

Within the operant extinction experiment, the effects of chlordiazepoxide in comparison with saline were just as have been obtained previously with this benzodiazepine in this procedure (e.g. Shaw.
