Rats were given a multiple stimulus discrimination, with either a constant positive stimulus combined with several negative stimuli or a constant negative stimulus combined with several positive stimuli. Choice data in transfer tests indicated that the discrimination had taken place on the basis of the constant stimulus alone and that the constant stimulus was equally effective in mediating transfer whether it had been positive or negative. While the multiple stimuli did not control choice behaviour, the latency data indicated that some analysis of them had taken place. Analyses of discrepancies in choice and latency data suggest that the two types of measure reflect different processes involved in discrimination learning.
