Abstract

Reports results from a taste-aversion study using 25 male Long-Evans rats in which ethanol was the unconditioned stimulus (UCS) and from 6 studies (N = 172) in which lithium chloride (LiCl) was the UCS: (a) Exposure to the UCS prior to conditioning retards subsequent acquisition of learned taste aversions. (b) A single preconditioning UCS exposure is sufficient to attenuate conditioning. (c) The preconditioning UCS exposure must occur within a limited period prior to conditioning to attenuate learning. (d) Repeated conditioning trials will override the effect of prior exposure to the UCS. (e) Tolerance to the UCS is not a necessary condition for the attenuation effect to occur. (f) Pairing the preconditioning UCS with a novel flavor other than the CS does not remove the preexposure effect, although it may reduce its magnitude. (g) The degree of disruption is a positive function of preconditioning UCS dosage and an inverse function of conditioning UCS dosage. (PsycINFO Database Record (c) 2006 APA, all rights reserved).
