Do recognition and priming index a unitary knowledge base? Comment on Shanks et al. (2003).
Whether sequence learning entails a single or multiple memory systems is a moot issue. Recently, D. R. Shanks, L. Wilkinson, and S. Channon advanced a single-system model that predicts a perfect correlation between true (i.e., error free) response time priming and recognition. The Shanks model is contrasted with a dual-process model that incorporates both response time priming and reportable sequence knowledge as predictors of recognition. The models were tested by applying confirmatory factor analysis to data obtained from a recognition test that was administered under both speed and accuracy conditions. The Shanks model accounted for the data in the speed condition, whereas the dual-process model provided a better fit in the accuracy condition. The results are compatible with the notion that cognitive processes were engaged differentially in recognition judgments under speed and accuracy conditions.
