以前的研究表明，由于写作是一种后期获得的复杂技能，它可能是儿童语言困难的一个特别敏感的指标。支持这一观点的证据是在一项研究中获得的，该研究将161名年龄在7.5至13岁之间的正常发育的对照儿童与75名同龄的双胞胎儿童进行了对比，这些儿童要么有特定的语言障碍，要么是受影响儿童的双胞胎。书面叙述，从儿童使用一系列的五张照片描绘一个简单的故事，并进行了分析，语法的复杂性和准确性，可理解性，语义内容。双胞胎中只有42人拼写得很好。足以完成叙事任务。一些受影响儿童的双胞胎在书面语言方面有缺陷，尽管口头语言测试表现正常。大多数有语言障碍的儿童在写作方面很差，尤其是在拼写和标点符号方面有明显的缺陷。语言障碍的儿童作出了一个相对较高比例的语音不准确的拼写错误时，与年幼的儿童在类似的词汇水平。那些在非单词重复测试中表现不佳的人尤其可能有糟糕的书面语言。然而，四个孩子与纯粹的语言困难产生的年龄适当的书面叙述。
Previous work has suggested that, because writing is a late-acquired and complex skill, it may be a particularly sensitive index of language difficulties in children. Evidence in support of this view was obtained in a study contrasting 161 normally-developing control children aged from 7.5 to 13 years with 75 twin children of the same age who either had specific speech-language impairments, or were co-twins of affected children. Written narratives were elicited from children using a sequence of five photographs depicting a simple story, and were analysed for grammatical complexity and accuracy, intelligibility, and semantic content. Only 42 of the twins could spell well. enough to attempt the narrative task. Some co-twins of affected children had deficits in written language, despite normal performance on oral language tests. Most children with language impairments were poor at writing, with particularly marked deficits on a measure of spelling and punctuation. Children with language impairments made a relatively high proportion of phonologically inaccurate spelling errors when compared with younger children at a similar vocabulary level. Those who did poorly on a nonword repetition test were especially likely to have poor written language. However, four children with pure speech difficulties produced age-appropriate written narratives.
