Effects of Uniqueness Points in Japanese Word Recognition

This paper investigated the effects of uniqueness points in Japanese word recognition by two different approaches. First, computational analyses of uniqueness points revealed that the probability that a word diverges from all the other words in the lexicon before word offset was only .48. The results therefore predict that words are not usually recognized before their offset in Japanese, similar to the results that Luce showed for English (1986). Second, the performance data showed that uniqueness points were effective on the processing times. The semantic categorization times and effects of uniqueness points were positively correlated whereas the auditory naming times and effects of uniqueness points were negatively correlated. The findings in this study were discussed in the current word recognition models.
