在语音学和发展心理学中，婴儿在词汇中表现语音细节的程度一直是一个争议的来源。一个突出的假设认为，婴儿以模糊或不准确的形式存储单词，直到学习发音相似的邻居迫使注意细微的语音差异。在这里报告的实验中，我们使用视觉固定任务来评估单词识别。我们提出的第一个证据表明，事实上，词汇表征的14个月和15个月大的孩子编码的细节，即使这个细节是没有必要的功能区分类似的话在婴儿的词汇。即使在词汇量激增之前，接触单词也足以形成明确的词汇表征。这些结果表明，在婴儿的言语表征的发展连续性：婴儿开始建立一个词汇和学习词义，他们使用的知觉能力，以前在测试任务中表现出的歧视和分类的无意义的音节。
The degree to which infants represent phonetic detail in words has been a source of controversy in phonology and developmental psychology. One prominent hypothesis holds that infants store words in a vague or inaccurate form until the learning of similar-sounding neighbors forces attention to subtle phonetic distinctions. In the experiment reported here, we used a visual fixation task to assess word recognition. We present the first evidence indicating that, in fact, the lexical representations of 14- and 15-month-olds are encoded in fine detail, even when this detail is not functionally necessary for distinguishing similar words in the infant's vocabulary. Exposure to words is sufficient for well-specified lexical representations, even well before the vocabulary spurt. These results suggest developmental continuity in infants' representations of speech: As infants begin to build a vocabulary and learn word meanings, they use the perceptual abilities previously demonstrated in tasks testing the discrimination and categorization of meaningless syllables.
