Abstract:The present paper reviews major studies on Specific Language Impairment (SLI) abroad, particularly those on the linguistic features of SLI children and the theoretical analyses of SLI. SLI has been studied by the international academia for many years, and the major focus has been on the acquisition of inflectional morphemes. The linguistic difference between SLI and High Functioning Autism (HFA) children is another widely explored theme in this field. Various hypotheses or models have been proposed to account for the causes of such deficits, such as perceptual deficit hypothesis, rule-deficit hypothesis, agreement deficit model, agreement and tense omission model, computational grammatical complexity hypothesis, derivational complexity hypothesis, among many others. In contrast, SLI has not received much attention in linguistic and applied linguistic studies in China, and very little is known about the linguistic characteristics of Mandarin-speaking children with SLI. However, it is believed that language data from Mandarin SLI children can bring a new perspective to the issue because inflectional morphology does not play a role in the development of grammar for Chinese-speaking children. To inform further studies on SLI in China, this study puts forward some suggestions, including the development of test scales and comprehensive evaluation tools for SLI.
