The effect of orthographic neighborhood in the reading span task.
This study aimed at examining whether and to what extent orthographic neighborhood of words influences performance in a working memory span task. Twenty-five participants performed a reading span task in which final words to be memorized had either no higher frequency orthographic neighbor or at least one. In both neighborhood conditions, each participant completed three series of two, three, four, or five sentences. Results indicated an interaction between orthographic neighborhood and list length. In particular, an inhibitory effect of orthographic neighborhood on recall appeared in list length 5. A view is presented suggesting that words with higher frequency neighbors require more resources to be memorized than words with no such neighbors. The implications of the results are discussed with regard to memory processes and current models of visual word recognition.
