Aspectual Production in Preschool Mandarin-speaking Children with Developmental Language Disorder

Using a priming picture-description, a digital recall and a non-word repetition task, this study tested 18 four- to six-year-old Mandarin-speaking children with Developmental Language Disorder (DLD) and 25 age-matched typically developing (TD) children to examine the performance of children with DLD in producing grammatical aspect and the links of their performance to verbal working memory (VWM). Results indicated that children with DLD performed worse in producing individual aspect markers than TD children, showing better performance on the preverbal zai- than on the post-verbal markers. They showed better performance in producing imperfective than perfective aspect. Heterogeneous performance was noted in aspectual production within the DLD group, but only performance on -guo and perfective aspect significantly correlated with their VWM. Findings highlight the importance of positional and aspectual distinctions in assessment and intervention for Mandarin-speaking children with DLD, and they provide language-specific evidence for cross-linguistic asymmetries in aspect acquisition in language disorders.
