The role of prosody and long-term phonological knowledge in Japanese children's nonword repetition performance

Abstract

This study investigated the effects of association values and the influences of prosodic information on Japanese children's repetition of nonwords with varying association values and with or without pitch accent. Fifteen 3- and 4-year-olds (mean age = 4.42 years, range: 3.9–4.9) and nineteen 5- and 6-year-olds (mean age = 5.71 years, range: 5.1–6.1) participated in this experiment. Concerning the nonword repetition scores, an effect of association value was found only in older children for consonants of nonwords only, whereas the effect of accent pattern was observed only in young children for both consonants and vowels of nonwords. The occurrences of both effects were connected to differences in the ages of the children and the types of phoneme in nonwords. We interpret these results in the context of the framework of phonological working memory.
