Neighborhood Effects on Spoken Word Recognition in Japanese

Reaction time of lexical decision and word recognition score were measured to investigate whether the neighborhood, a word candidate set with single mora substitution with a target word, has inhibitory effects on spoken word recognition in Japanese. Partial correlation analyses were conducted between subjects’ performance of spoken word recognition (reaction time and recognition score) and neighborhood properties (density, mean familiarity, maximum familiarity, and sum of familiarity). The results showed significant inhibitory effects of neighborhood on the recognition score but not on the reaction time. It is suggested that some amount of time is necessary for the neighborhood to be activated and to compete with a target word in spoken word recognition in Japanese.
