Abstract

Two experiments investigated the relative salience of gustatory and visual cues in the formation of poison-based aversions by guinea pigs. In the first experiment, it was shown that when guinea pigs were made sick following the consumption of red water that had been sweetened they formed aversions only to the sweet taste and not to the appearance. In the second experiment, animals that had been habituated to saccharin water prior to training were able to form aversions to the red appearance of the water when they were made sick following ingestion of water that was both red in appearance and sweet tasting. These results indicated that the salience of the weaker cue was influenced by changes in the salience of the stronger one.
