  • Title: Stimulus compounding enhances conditioned suppression produced by cocaine-paired stimuli.
    Author: Panlilio LV, Weiss SJ, Schindler CW.
    Journal: Exp Clin Psychopharmacol; 2000 Feb; 8(1):6-13. PubMed ID: 10743900.
    Abstract:
    When 2 stimuli that occasion cocaine self-administration are presented in compound, their ability to increase cocaine-reinforced operant responding is substantially enhanced. The goal of the present experiment was to determine whether stimulus compounding could produce analogous enhancements of a classically conditioned drug effect. Food-maintained responding in rats was suppressed by a tone and a light that were individually paired with response-independent cocaine (3 mg/kg iv). This conditioned suppression was significantly enhanced when the stimuli were presented together in a stimulus-compounding test. The magnitude of this enhancement was similar to that in previous studies in which responding was suppressed by shock-paired stimuli. These results demonstrate that multiple drug-related cues interact in a predictable manner to influence both operant and classically conditioned behavior.
