Abstract
In this experiment, we evaluated whether extinction of taste aversion following conditioning with a compound CS of visual and taste cues would attenuate taste-mediated aversion to visual cues. Sixty chicks (Gallus domesticus) received a pairing of a compound CS, red-colored water or red-colored vinegar, with a toxin and then extinction procedures with clear vinegar. Testing with red water showed reliable evidence of potentiation to visual cues in the red vinegar conditioning groups, as measured by latency to start drinking and intake performance. Taste-aversion extinction groups (n = 30), tested with clear vinegar, showed no reliable evidence of taste aversion. The results contradicted the within-compound hypothesis of taste-mediated potentiation and replicated Lett (1984).
