Abstract:

A model of the effects of context and frequency on word recognition is presented. By employing a post-access checking mechanism which is argued to be essential for resolving lexical and perceptual ambiguity, the model accounts for both facilitatory and inhibitory effects of word recognition without the use of either lexical priming or an attentional mechanism. The post-access checking mechanism is assumed to opertate by modifying the recogmition criteria for a subset of lexical entries determind on the basis of perceptual analysis. The behaviour of criterion bias models of this form is discussed in some detail and it is shown that models of this form provide an accurate account of the effect of context on both speed and accuracy of word recognition in reaction time tasks.
