Bouton, Dunlap, and Swartzentruber (1987) and Davis, Best, and Grover (1988) have shown that the aversion conditioned to a target taste can be enhanced or potentiated by the presence of a second taste during the conditioning episode. In the present experiment, groups of young (80-day-old) and old (150-day-old) rats were exposed to a CS composed of one or two tastes, respectively, prior to lithium-induced toxicosis. The results indicated that taste potentiation was shown by the younger subjects only when weaker fluid concentrations were employed. However, the effect was shown by the older animals under both weak and strong concentrations.
