In three experiments, the processing of words that had the same overall number of neighbors but varied in the spread of the neighborhood (i.e., the number of individual phonemes that could be changed to form real words) was examined. In an auditory lexical decision task, a naming task, and a same-different task, words in which changes at only two phoneme positions formed neighbors were responded to more quickly than words in which changes at all three phoneme positions formed neighbors. Additional analyses ruled out an account based on the computationally derived uniqueness points of the words. Although previous studies (e.g., Luce & Pisoni, 1998) have shown that the number of phonological neighbors influences spoken word recognition, the present results show that the nature of the relationship of the neighbors to the target word--as measured by the spread of the neighborhood--also influences spoken word recognition. The implications of this result for models of spoken word recognition are discussed.
在三项实验中，研究了具有相同邻词总数但邻域范围不同（即可以通过改变单个音素从而形成真实单词的数量）的单词的加工过程。在听觉词汇判断任务、命名任务和异同任务中，仅在两个音素位置发生变化就能形成邻词的单词，其反应速度比在所有三个音素位置都发生变化才能形成邻词的单词更快。进一步的分析排除了基于单词计算得出的独特性得分的解释。尽管先前的研究（如Luce和Pisoni，1998）表明语音邻词的数量会影响口语单词识别，但目前的结果表明，邻词与目标词的关系性质（通过邻域范围来衡量）也会影响口语单词识别。本文讨论了这一结果对口语单词识别模型的意义。
