Priming for previously studied words in an implicit auditory memory task has been interpreted as evidence for a presemantic perceptual representation system that encodes acoustic representations of words (B. A. Church & D. L. Schacter, 1994). In this article, 3 experiments provided evidence that such priming may result instead from a bias to respond with studied words. In forced-choice identification with similar alternative choices, there was no overall improvement in performance due to prior study. Benefits for studied test words were offset by costs for similar but nonstudied test words. Prior study had no effect when forced-choice alternatives were dissimilar. The data are discussed in relation to current models of auditory information processing and a new model (R. Ratcliff & G. McKoon, in press) for priming in visual word identification.

J. L. Nicol and D. Swinney (1989) reported facilitation in a cross-modal lexical-decision task as evidence that implicit objects of verbs (WH-traces) are reinstated during comprehension. G. McKoon and R. Ratcliff (1994) found the same priming effects in the absence of implicit objects, suggesting that the effects are attributable to some factor other than a syntactic process that would fill in implicit objects. J. L. Nicol, J. D. Fodor, and D. Swinney (1994) questioned the relevance of McKoon and Ratcliff's findings because they were obtained with all-visual rather than cross-modal presentation. In 2 experiments, the authors replicated McKoon and Ratcliff's results using cross-modal lexical decision.
