Familiarity effects and word unitization in visual comparison tasks

Abstract

The decision that two words are identical is made more quickly than the decision that two nonwords are identical. This familiarity effect was shown to be larger in a simultaneous matching task than in a sequential matching task. In the simultaneous task, two words were not matched as quickly as a single letter and a letter in a predesignated location within a word. The latter finding rules out a perceptual unitization account of the familiarity effect (Silverman, 1985). The familiarity effect was interpreted to be due to the facilitated encoding of a comparison item when a holistic cognitive unit representing the target is activated in memory. © 1989 Psychonomic Society, Inc.
