目的最近的研究表明，非单词重复(NWR)和句子重复(SR)任务可以用于区分SLI儿童和他们典型的发育年龄匹配(TDAM)和更年轻(TDY)的同龄人。方法对14例SLI粤语儿童和30例TDAM、TDY同龄人的NWR和SR任务进行比较。比较了IN非词(语言中已证明的CV组合)和OUT非词(未在语言中证明的CV组合)的NWR。使用4种不同的评分方法对SR表现进行比较。结果SLI组在NWR测试中的得分并不显著低于TDAM组(总体结果为TDAM=SLI>；TDY)。在IN音节上差异不显著，在OUT音节上差异不显著。这一结果并不表明说粤语的SLI儿童在语音工作记忆方面存在局限性。SR任务区分儿童和他们的TDAM同龄人，但不区分SLI儿童和他们的TDY同龄人，他们的平均话语长度匹配。结论SR而不是NWR区分SLI儿童和他们的TDAM同龄人。对于说英语的SLI儿童来说，较差的NWR可能是由于在单词重复中较少使用红色整合策略。需要对加工策略进行进一步的跨语言研究。
PURPOSE Recent research suggests that nonword repetition (NWR) and sentence repetition (SR) tasks can be used to discriminate between children with SLI and their typically developing age-matched (TDAM) and younger (TDY) peers. METHOD Fourteen Cantonese-speaking children with SLI and 30 of their TDAM and TDY peers were compared on NWR and SR tasks. NWR of IN nonwords (CV combinations attested in the language) and OUT nonwords (CV combinations unattested in the language) were compared. SR performance was compared using 4 different scoring methods. RESULTS The SLI group did not score significantly lower than the TDAM group on the test of NWR (overall results were TDAM = SLI > TDY). There were nonsignificant group differences on IN syllables but not on OUT syllables. The results do not suggest a limitation in phonological working memory in Cantonese-speaking children with SLI. The SR task discriminated between children and their TDAM peers but not between children with SLI and their TDY peers matched for mean length of utterance. CONCLUSIONS SR but not NWR discriminates between children with SLI and their TDAM peers. Poorer NWR for English-speaking children with SLI might be attributable to weaker use of the redintegration strategy in word repetition. Further cross-linguistic investigations of processing strategies are required.
