为了分离出语言的特性，这些特性的发展可以承受学习条件的广泛变化，我们观察了那些没有获得任何常规语言输入但经历了正常社会环境的儿童。我们研究的孩子都是失聪的，听力损失严重，他们不能自然地获得口语，他们的听力父母选择不让他们接触手语。在以前的工作中，我们证明，尽管他们缺乏传统的语言输入，孩子们开发自发的手势系统，结构在句子的水平上，在一个句子中的手势识别，类似于句法结构。本研究的目的是确定这些聋儿的手势系统是否在第二个层次上，即手势的层次上结构化，也就是说，手势中是否有类似于形态结构的结构？我们发现：（1）聋儿的手势可以用手形和动作组合的范例来表征，这些范例形成了他几乎所有自发手势的矩阵;（2）聋儿的手势系统比他的听力母亲提供的模型复杂得多。这些数据强调了儿童对词内结构规则性的贡献，并表明这种结构是语言的弹性属性。
In order to isolate the properties of language whose development can withstand wide variations in learning conditions, we have observed children who have not had access to any conventional linguistic input but who have otherwise experienced normal social environments. The children we study are deaf with hearing losses so severe that they cannot naturally acquire spoken language, and whose hearing parents have chosen not to expose them to a sign language. In previous work, we demonstrated that, despite their lack of conventional linguistic input, the children developed spontaneous gesture systems which were structured at the level of the sentence, with regularities identifiable across gestures in a sentence, akin to syntactic structure. The present study was undertaken to determine whether one of these deaf children's gesture systems was structured at a second level, the level of the gesture – that is, were there regularities within a gesture, akin to morphologic structure?We have found that (1) the deaf child's gestures could be characterized by a paradigm of handshape and motion combinations which formed a matrix for virtually all of his spontaneous gestures, and (2) the deaf child's gesture system was considerably more complex than the model provided by his hearing mother. These data emphasize the child's contribution to structural regularity at the intra-word level, and suggest that such structure is a resilient property of language.
