• Purpose: Nonword repetition (NWR) tasks could be used to discriminate between specific language impairment (SLI) and typically developing children (TDC) in English-speaking children. I propose to use NWR task in Japanese language and to establish a standard to discriminate SLI at a younger age. Method: Participants were children who had attended nursery school. The 117 subjects ranged in age from 3-years, 1-month to 6-years, 1-month, and were thought to be TDC, but may have included some with SLI. They were examined to investigate their ability in phonological working memory. As well, an NWR task in Japanese was compared with different tasks associated with language development testing. These included a Picture Vocabulary Test (PVT), naming, digit span, and articulation errors. Results: The NWR task correlated with age, vocabulary age, naming, and digit span. The group less then one-and-a-half-years-old showed individual variations. The mean percentage of correct answer in the NWR task of four syllables comprised almost 70% by age three-and-a-half. In addition, the subjects made phoneme errors only with one-syllable words, those being the least significant, i.e., replacing /t/ with /k/. Conclusion: The results suggested that a Japanese NWR task is a useful clinical marker in discriminating between SLI and TDC.
