Purpose A systematic review was performed to determine the extent to which orthographic facilitation, a strategy to improve word learning, has been demonstrated in the literature for children and adolescents from clinical categories such as developmental language disorders (DLD), autism spectrum disorders (ASD), Down syndrome, dyslexia, hearing impairment, intellectual disability, and cerebral palsy. Method Five databases were searched for all studies published through December 2019. Eligible studies included participants from a clinical population (DLD, ASD, dyslexia, cerebral palsy, Down syndrome, hearing impairment, etc.) and compared word learning with and without orthography. Selected studies were extracted for pertinent information. In addition, assessment of the methodological rigor was performed for each study. Results The review yielded five studies that targeted word learning with orthographic facilitation for children from various clinical populations including DLD, verbal children with autism, Down syndrome, and dyslexia. All studied populations showed a benefit for word learning in picture naming posttests when words were trained in the presence of orthography. Conclusions For the studied populations, training words in the presence of orthography will improve word learning accuracy and retention. The review highlights the need for more research in this area across other clinical populations. Supplemental Material https://doi.org/10.23641/asha.14632791.

临床人群中单词学习的正字法支持：系统评价。

目的 进行系统评价以确定正字法促进（一种改善单词学习的策略）在儿童和青少年临床类别（如发育性语言障碍 (DLD)、自闭症谱系障碍 (ASD)）的文献中得到证实的程度, 唐氏综合症、阅读障碍、听力障碍、智力障碍和脑瘫。方法 检索 5 个数据库，检索截至 2019 年 12 月发表的所有研究。 符合条件的研究包括来自临床人群（DLD、ASD、阅读障碍、脑瘫、唐氏综合症、听力障碍等）的参与者，并比较使用和不使用拼写法的单词学习。提取选定的研究以获取相关信息。此外，对每项研究都进行了方法学严谨性的评估。结果 该评价产生了五项研究，这些研究针对来自各种临床人群的儿童，包括 DLD、患有自闭症、唐氏综合症和阅读障碍的儿童，通过正字法促进单词学习。当在正字法存在的情况下训练单词时，所有研究的人群都显示出在图片命名后测中单词学习的好处。结论 对于研究人群，在拼写的情况下训练单词将提高单词学习的准确性和保留率。该评论强调需要在其他临床人群中在该领域进行更多研究。补充材料 https://doi.org/10.23641/asha.14632791。当在正字法存在的情况下训练单词时，所有研究的人群都显示出在图片命名后测中单词学习的好处。结论 对于研究人群，在拼写的情况下训练单词将提高单词学习的准确性和保留率。该评论强调需要在其他临床人群中在该领域进行更多研究。补充材料 https://doi.org/10.23641/asha.14632791。当在正字法存在的情况下训练单词时，所有研究的人群都显示出在图片命名后测中单词学习的好处。结论 对于研究人群，在拼写的情况下训练单词将提高单词学习的准确性和保留率。该评论强调需要在其他临床人群中在该领域进行更多研究。补充材料 https://doi.org/10.23641/asha.14632791。
