Orthographic and phonological activation in auditory and visual word recognition.

Abstract

A discrete-trials color naming (Stroop)’paradigm was used to examine activation along orthographic and phonological dimensions in visual and auditory word recognition. Subjects were presented a prime word, either auditorily or visually, followed 200 msec later by a target word printed in a color. The orthographic and phonological similarity of prime-target pairs varied. Color naming latencies were longer when the primes and targets were orthographically and/or phonologically similar than when they were unrelated. This result obtained for both prime presentation modes. The results suggest that word recognition entails activation of multiple codes and priming of orthographically and phonologically similar words.
