A counter model for implicit priming in perceptual word identification.

Abstract: A model for the identification of briefly presented words is presented The model accounts for data from naming and forced-choice experiments in which factors such as similarity of alternatives and stimulus presentation time are varied The model assumes that counts are accumulated in counters that correspond to words and that a word is chosen as a response when the number of counts in its counter exceeds the maximum of the numbers of counts in other counters by a criterial value Prior exposure to a word causes its counter to attract more counts than it otherwise would, and this yields priming effects Ten experiments are presented, and the model provides correct predictions for the data Implications of the model for research in implicit memory are considered

Bias in Auditory Priming

Abstract: 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.
