Abstract
Two groups of animals were trained on simultaneous discriminations. On each trial one alternative was vertical, the other horizontal; one was black and the other white. The vertical was rewarded for both groups. For one group, black-white was also relevant (and redundant) while for the other black-white was irrelevant. When black-white was relevant, learning about the comparatively difficult orientation cue was suppressed. Theoretical implications are discussed.
