为了确定语音起始时间(VOT)中的微小类别差异是否会影响词汇通达，当参与者指出四幅图片中哪一幅是由语音起始时间(VOT)连续变化的语音刺激命名时，他们监测了眼球运动。VOT的类别内差异导致当VOT接近类别边界时，对跨界词汇竞争者的注视梯度增加。因此，细粒度的声学/语音差异被保存在竞争候选词汇的词汇激活模式中，并可用于最大化在线单词识别的效率。(C)2002 Elsevier Science B.V.保留所有权利。
In order to determine whether small within-category differences,in voice onset time (VOT) affect lexical access, eye movements were monitored as participants indicated which of four pictures was named by spoken stimuli that varied along a 0-40 ms VOT continuum. Within-category differences in VOT resulted in gradient increases in fixations to cross-boundary lexical competitors as VOT approached the category boundary. Thus, fine-grained acoustic/phonetic differences are preserved in patterns of lexical activation for competing lexical candidates and could be used to maximize the efficiency of on-line word recognition.
