Abstract
Garcia & Koelling (1966) showed that if rats are poisoned after ingesting a flavored solution in the presence of audiovisual cues, they will subsequently avoid only the taste stimulus, whereas if they are shocked, they learn to avoid only the audiovisual cues. The present experiments replicated these findings with one major change in experimental conditions: both taste and nongustatory CSs were presented in the absence of approach and ingestive behaviors to minimize involvement of ingestion in the associative process. (The taste CS was presented by flushing the oral cavity with a saccharin solution under conditions in which the rat would not drink.) Despite these changes, Garcia and Koelling’s results were confirmed.
