| Abstract: | Reports an error in the original article by J. R. Troisi, II and Chana Akins (Experimental and Clinical Psychopharmacology, 2004, Vol. 12, No. 4, pp. 237-242). The first sentence of the abstract, "Two groups of male Japanese quail (Coturnix japonica) to discriminate cocaine from saline in a conditioned approach procedure maintained by sexual reinforcement," was incomplete. The correct wording is "Two groups of male Japanese quail (Coturnix japonica) were trained to discriminate cocaine from saline in a conditioned approach procedure maintained by sexual reinforcement." (The following abstract of this article originally appeared in record 2004-20800-003.) Two groups of male Japanese quail (Coturnix japonica) to discriminate cocaine from saline in a conditioned approach procedure maintained by sexual reinforcement. For 1 group, cocaine (10 mg/kg ip) was administered prior to a conditioned stimulus (CS) that predicted copulation; saline followed by a CS predicted no copulation. A second group underwent the opposite training regimen. Results revealed apparent between-group differences in the rates of acquisition of the discrimination; however, during extinction trials, both groups responded more under the drug condition that predicted the female than to the condition that predicted no female. The results suggested that a drug discrimination may be maintained by sexual reinforcement. The findings are discussed with regard to interactions of cocaine and sexual reward, as well as to Pavlovian conditional stimulus control (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
