Abstract
Gustatory aversions, induced in rats by conditionally pairing a distinctive flavor with a noxious drug, were readily established even when injections were delayed an hour or more. The optimal interstimulus interval and effectiveness of cues for learning appear to be a function of the specific effects of the reinforcer on the organism.
