To evaluate whether previously observed age differences in long-delay taste aversion were due to age-related differences in the shared association of contextual cues and CS with the US, weanling, young-adult, and old-adult rats were given a NaCl or LiCl US immediately after or a LiCl US 3 hr. after a saccharin CS presentation in a black or white context. They were then given a context-preference test in a chamber which was half black and half white. Analysis showed rats, irrespective of age or conditioning context, spent a significantly smaller percentage of time on the white side than on the black side of the test chamber. These results suggest that age differences in long-delay taste-aversion conditioning are not due to age-related differences in the shared association of contextual cues and CS with the US.
