当参与者在电脑屏幕上听到句子和看到四个图片物体时，他们的眼球运动被监控。参与者被要求点击句子中提到的物体。当目标单词（如仓鼠）的第一个音节被单音节单词的录音取代时，与来自目标单词的不同录音相比，对代表单音节单词（如ham）的图片的短暂注视更多。这表明，音位相同的序列可以包含调节其词汇解释的线索。这种影响是由序列的持续时间决定的，而不是由它的来源（即它来自哪种类型的单词）决定的。序列越长，产生的单音节词解释就越多。我们认为，词汇嵌入消歧义的线索，如片段延长，来自于韵律边界的实现，而韵律边界通常跟随单音节单词，并且单词边界与韵律边界一致的词汇候选词在单词识别过程中更受青睐。(C) 2003 Elsevier B.V.所有航班预订。
Participants' eye movements were monitored as they heard sentences and saw four pictured objects on a computer screen. Participants were instructed to click on the object mentioned in the sentence. There were more transitory fixations to pictures representing monosyllabic words (e.g. ham) when the first syllable of the target word (e.g. hamster) had been replaced by a recording of the monosyllabic word than when it came from a different recording of the target word. This demonstrates that a phonemically identical sequence can contain cues that modulate its lexical interpretation. This effect was governed by the duration of the sequence, rather than by its origin (i.e. which type of word it came from). The longer the sequence, the more monosyllabic-word interpretations it generated. We argue that cues to lexical-embedding disambiguation, such as segmental lengthening, result from the realization of a prosodic boundary that often but not always follows monosyllabic words, and that lexical candidates whose word boundaries are aligned with prosodic boundaries are favored in the word-recognition process.
