The basis for performance of actions that deliver conditioned reinforcement has seen little recent experimental examination, yet conditioned reinforcement has become employed as a major behavioral assay in studies of psychostimulant drugs of abuse. The current series sought both to elucidate the structure of conditioned reinforcement and to demonstrate the importance of sensory reinforcement controls in studies employing conditioned reinforcement. Conditioned reinforcers were found to act as genuine goals of instrumental responding---although animals did not reinstate when presented with conditioned reinforcers, they did show standard instrumental contingency degradation when the conditioned reinforcer was freely delivered. The motivational basis of the reward value of conditioned reinforcement was less clear. Shifts in motivational state and outcome devaluation via specific satiety treatments both failed to show any role of the value of the unconditioned stimulus that was predicted by the conditioned reinforcer in motivating instrumental responding for that conditioned reinforcer. Alternative motivational structures were therefore considered. Finally, one psychostimulant drug, amphetamine, was demonstrated to have reliable effects on both responding for conditioned reinforcement and sensory reinforcement control stimuli, a finding that casts serious doubts on experiments failing to employ that control.Subjects--Topical Terms:
