Abstract
Recent evidence suggests that many cognitive tasks thought to use abstract representations may instead use specific episodes. The research reported here examined the possibility that words are identified through the retrieval of prior occurrences rather than through the activation of abstract lexical representations. The influence of several variables on repetition priming in the perceptual identification task was investigated. Experiments 1 and 2 manipulated the font and the context in which words were studied and tested. Unexpectedly, high- and low-frequency words were affected differently. Because abstraction-based accounts predict no effect of changes in font, these results favor an episode-based account. The goal of Experiment 3 was to obtain constraints for use in formulating an episode-based model. It was found that the effects of studying an orthographically-similar neighbor depended both on frequency and on the fonts in which the words were presented. An episode-based model is proposed in which episodes are retrieved according to their perceptual, conceptual, and episodic similarity to cues generated during the processing of a word. The retrieved episodes are then used by decision processes to arrive at an identification response.
