Effects of a preferred vs a nonpreferred CS in the establishment of a taste aversion

Abstract

Following ingestion of either saccharin-flavored water (a preferred substance) or HCL-flavored water (nonpreferred), two groups of mice were injected intraperitoneally with an illness inducer to establish a conditioned taste aversion. After 2 recovery days, the aforementioned procedure was repeated, followed by 2 more recovery days. An extinction trial was then introduced, which consisted of presenting the taste cues and omitting the injections. Results indicated that the aversion to the HCL was stronger in all cases than it was to the saccharin. © 1974, Psychonomic Society, Inc.. All rights reserved.
