为了研究听觉信息和词汇知识（特别是语音序列是单词的知识）在语音感知中的相互作用，构建了语音起始时间不同的声学连续统，以便对于每个声学连续统，两个可能的语音分类中的一个产生单词，另一个没有。例如，一个连续体的范围在单词dash和非单词tash之间;另一个连续体使用非单词dask和单词task。在两个实验中，受试者表现出了显著的词汇效应--也就是说，他们倾向于进行语音分类，从而形成单词。这种词汇效应在音素边界（听觉信息模糊的地方）比在condinua的两端更大。因此，词汇效应必然出现在对词汇知识和听觉信息都敏感的加工阶段。
To investigate the interaction in speech perception of auditory information and lexical knowledge (in particular, knowledge of which phonetic sequences are words), acoustic continua varying in voice onset time were constructed so that for each acoustic continuum, one of the two possible phonetic categorizations made a word and the other did not. For example, one continuum ranged between the word dash and the nonword tash; another used the nonword dask and the word task. In two experiments, subjects showed a significant lexical effect--that is, a tendency to make phonetic categorizations that make words. This lexical effect was greater at the phoneme boundary (where auditory information is ambiguous) than at the ends of the condinua. Hence the lexical effect must arise at a stage of processing sensitive to both lexical knowledge and auditory information.
