In the present study, we investigated the grammaticality judgement skills of children with developmental language impairments. The participants included 20 children with language impairments of ages ranging from 7 to 9 years and of IQ’s ranging from 71 to 84, and 40 normally developing children. Twenty normal children were matched with the language impaired children in their language ages and the other 20 normal children were matched with the language impaired children in their chronological ages. The children were asked to judge the grammatical correctness of 48 short sentences, half of which were ungrammatical sentences containing incorrect case-markers and the other half were grammatically correct sentences. Four types of case-markers including nominative "i/ga", accusative "ul/lul", locative "e," and instrumental "ro" were systematically changed to generate the ungrammatical sentences. The language impaired children performed worse than both groups of normally developing children in detecting the ungrammatical sentences and in correcting the case-markers of those sentences. In detecting the errors of ungrammatical sentences, the language impaired children exhibited variable performances across the different case-markers.
