Abstract
The longevity of taste memory was assessed using a simple delayed discrimination procedure. Memory for taste exhibits long-lived properties in conditioned taste aversions, in which delays of up to 12 h between taste presentation and toxicosis are commonly reported. Although the discrimination procedure utilized here was designed to approximate the parametric features of taste aversion learning (one trial per day, a long period of exposure to the taste, and a salient reinforcer), obtained delays were under 1 min. The differences in taste memory within different procedures are discussed in the context of a retrospective retrieval process for ingestion-related stimuli.
