| Abstract: | Testa and Ternes have proposed that the degree of spatial contiguity between a cue and a food object is an important determinant of the associability of that cue with toxicosis. We found, in accord with the Testa and Ternes hypothesis, that rats showed more profound illness-based aversions to the visual properties of food objects than to the visual properties of food bins or feeding chambers. This result has implications for the design of experiments undertaken to determine the relative associability of cues in different sensory modalities with toxicosis. |
