手语是通过同时的上半身运动来表达的，并且被看到;口语是通过连续的声道运动来表达的，并且被听到。但这两种语言模式中的单词识别都需要将连续输入分割成离散的词汇单元。根据可能词约束（PWC），听者分割语音，以避免输入中的不可能的单词。我们在这里认为，预委会是一个模式一般的原则。英国手语（BSL）的聋人手语者发现，当无意义的符号是可能的BSL符号时，比当它们不是时，更容易发现嵌入在无意义符号上下文中的真实的BSL符号。控制实验表明，有没有不同的上下文之间的发音差异。第二个控制实验的分割在荷兰语口语加强声称，主要的BSL结果可能反映了操作的词汇可行性约束。看来，签署和口头语言，尽管激进的输入差异，被分割，以使没有残留的输入，不能是单词。皇冠版权所有（C）2009由爱思唯尔公司出版。All rights reserved.
Signed languages are articulated through simultaneous upper-body movements and are seen; spoken languages are articulated through sequential vocal-tract movements and are heard. But word recognition in both language modalities entails segmentation of a continuous input into discrete lexical units. According to the Possible Word Constraint (PWC), listeners segment speech so as to avoid impossible words in the input. We argue here that the PWC is a modality-general principle. Deaf signers of British Sign Language (BSL) spotted real BSL signs embedded in nonsense-sign contexts more easily when the nonsense signs were possible BSL signs than when they were not. A control experiment showed that there were no articulatory differences between the different contexts. A second control experiment on segmentation in spoken Dutch strengthened the claim that the main BSL result likely reflects the operation of a lexical-viability constraint. It appears that signed and spoken languages, in spite of radical input differences, are segmented so as to leave no residues of the input that cannot be words.
