IN PAVLOVIAN CONDITIONING, when two conditioned stimuli (CS) are presented together in a compound, the less potent and/or less salient of the two might not acquire any associative strength. That is, when tested in isolation, only the potent stimulus reveals conditioning (Kamin, 1969; Mackintosh, 1971; Pavlov, 1927). The weaker stimulus is said to be overshadowed (Pavlov, 1927) by the stronger one. Because the weaker of the two components is redundant, its presentation predicts nothing that is not predicted by the stronger component alone. A selective attention model (see Mackintosh, 1975) might explain this effect.
