A cohort of 37 pre-term children was assessed for both morphosyntactical and for vocabulary skills at the age of 2 and again at the age of 3 years and 6 months. They were compared with two comparison groups of full-term children (adjusted age and chronological age). The results indicated (1) a clear asynchrony between the two components of language production assessed at both ages, (2) an accurate prediction of language delay at age 2 for pre-term children (35% of pre-term children were detected for morphosyntax as measured by Mean Length of Utterance and 27% of pre-term children were detected for vocabulary as measured by the number of different words) and, (3) no evidence on the relationship of language and motor development as measured by formal tests. Such findings strongly challenge the validity of standardized developmental tests and support to a certain extent the hypothesis that language development is independent of motor skills. A neurodevelopmental assessment is suggested.
对一组37名早产儿在2岁时以及3岁6个月时进行了形态句法和词汇技能评估。将他们与两组足月儿对照组（矫正年龄组和实际年龄组）进行比较。结果表明：（1）在两个年龄阶段评估的语言产生的两个组成部分之间存在明显的不同步；（2）对早产儿2岁时的语言延迟有准确的预测（用话语平均长度衡量，35%的早产儿在形态句法方面被检测出有延迟，用不同单词数量衡量，27%的早产儿在词汇方面被检测出有延迟）；以及（3）通过正式测试衡量，没有证据表明语言与运动发育之间存在关联。这些发现强烈质疑了标准化发育测试的有效性，并在一定程度上支持了语言发育独立于运动技能的假说。建议进行神经发育评估。
