A taste aversion to saccharin was induced under conditions of satiation or deprivation. Subsequent testing occurred under the same or opposite conditions. A preference test yielded significant drug-placebo effects only under similar training and testing conditions. Ss trained and tested under satiation produced the greatest drug-placebo differences. The data are discussed in terms of state dependency and the procedures used to induce and measure the taste aversion.
Weanling rats were trained on a taste aversion task and tested 60 days later using the single bottle and preference methods for assessing the retention of a taste aversion, and a competitive situation in which the CS was eventually substituted for plain water. Only the competitive situation showed the effects of the early taste aversion training. The results are discussed in terms of the conditioning and reactivation of adrenocortical steroid elevations and how these might affect subsequent retrieval.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
