对11名聋哑儿童的手语和运动发育进行了为期16个月的研究。期这些受试者表现出早期语言发展的加速，平均而言，他们在8.5个月时就产生了第一个可识别的标志，13.2月10日的第10个签名。第一个符号组合出现在17.0 mo。学习说话的儿童通常要到2-3个月才能达到相应的口语里程碑。后受试者的50个符号词汇的结构和内容与先前发表的口语习得研究中同一阶段儿童的词汇结构和内容非常相似。先前由儿童学习说话的研究者报告的运动和语言发展之间的同步模式并不适用于本研究的人群：大多数学习手语的受试者在达到新的运动里程碑后，语言习得的速度并没有减慢，而是继续显示出他们的手语词汇量逐渐增加。
The sign language and motor development of 11 young children of deaf parents were studied across a 16 mo. period. The subjects showed accelerated early language development producing, on the average, their 1st recognizable sign at 8.5 mo., their 10th sign at 13.2 mo. and their 1st sign combination at 17.0 mo. Children learning to speak typically do not attain the equivalent spoken language milestones until 2-3 mo. later. The structure and content of the subjects'' 50-sign vocabularies closely resembled those for children at the same stage in previously published studied of spoken language acquisition. The pattern of synchrony between motor and language development previously reported by investigators of children learning to speak did not apply to the population of the present study: most of the subjects learning to sign did not slow down in their rate of language acquisition after achieving a new motor milestone but rather continued to show a gradual increase in the size of their sign language vocabularies.
