Resumen

Four experiments tested the effect of signaled and unsignaled preexposure to an unconditioned stimulus/stimuli (UCS) on conditioning of a taste aversion to saccharin, which was induced by pairing the saccharin conditioned stimulus/stimuli (CS) with lithium chloride (LiCl [UCS]). Rats of 2 ages were tested: weanlings 21 days old and adults 60–80 days old. In Exp 1, preexposure to a UCS signaled by a novel odor (banana) facilitated conditioning in the weanlings but not in the adults. Exp 2 replicated these data. Exp 3 determined that saccharin-LiCl conditioning was facilitated by a prior pairing of the banana odor and LiCl, but only if the LiCl doses were the same for the signaled UCS preexposure and for the taste-aversion conditioning itself. In all experiments, a conditioned aversion was enhanced in weanlings but not adults by prior pairing of an unrelated odor with LiCl. (PsycINFO Database Record (c) 2016 APA, all rights reserved)
