20 female albino Simonsen rats received paired injections of either ethanol or saline as the CS and LiCl as the UCS in a Pavlovian differential conditioning paradigm. LiCl evoked a large deceleration in heart rate (80-200 beats/min) as a UCR. As a result of 10 conditioning trials, the substance paired with LiCl elicited a lower average heart rate than that elicited by the unpaired substance. Moreover, Ss that received ethanol-LiCl injections subsequently were more averse to the taste of ethanol than Ss receiving saline-LiCl pairings. However, there were no differences in ethanol's ability to serve as the UCS to induce an aversion to a novel flavor solution (i.e., the Avfail phenomenon was not observed). The overall pattern of results underscores the value of using multiple indexes of learning in drug-drug conditioning paradigms. (21 ref) (PsycINFO Database Record (c) 2006 APA, all rights reserved).
