| Research Abstract |
Specific language impairment (SLI) has been said to be a disorder of language acquisition in children who do not have any other apparent cognitive, social, or neurological deficits that can account for their impairment. However, there have been few studies on the linguistic characteristics of Japanese SLI children.
We conducted a detailed case study of a Japanese G-SLI child. G-SLI children are considered to be a subtype of SLI children, who appear to inconsistently manipulate core aspects of syntax, including tense, agreement marking, and assigning thematic roles in passive sentences. The results of this study suggested that there exist G-SLI children in Japanese. In addition, it is suggested that the linguistic characteristics of Japanese G-SLI children include errors of tense-marking, case-marking and difficulty with passives, similar to those reported in other languages.
Moreover, we investigated the grammatical knowledge of 3 Japanese G-SLI children concerning grammatical Case. The results showed that the performance of the G-SLI children was poorer than that of 5 age-matched normally developing children in relation to Case assignment. The findings also demonstrated that their performance with scrambled sentences differed most substantially.
