Linguistic study on the nature and treatment of Japanese specific language impairment

本研究的目的是通过检查两名日本儿童的纵向数据，探讨日本儿童的性质和治疗的特殊语言障碍（SLI）。这项纵向研究的结果表明，虽然词汇方面（接受性词汇）的语言发展迅速，语法方面（时态和被动）没有在SLI儿童。此外，本研究的结果表明，这类儿童试图通过补偿策略来获得被动句。因此，研究代偿策略对发展儿童SLI的治疗方法至关重要。

The purpose of this study was to investigate the nature and treatment of Japanese children with specific language impairment (SLI) by examining the longitudinal data of the two Japanese children with SLI. The results of this longitudinal study demonstrate that while lexical aspects (receptive vocabulary) of language develop rapidly, grammatical aspects (TENSE and PASSIVES) do not in children with SLI. In addition, the results of this study show that such children try to acquire passives by means of compensatory strategies. Therefore it is suggested that the study of compensatory strategies is crucial to the development of the method of treatment for children with SLI.
