日本語における言い間違いの発達過程―5–13歳児及び成人を対象とした発話誘発課題による検証―

抄録

This study investigated the developmental changes in Japanese children’s speech inaccuracies through an elicited production task. The difficulty of segments, complexity of words in which the segments were embedded, and length of carrier sentences, were manipulated. The results revealed that inaccuracies occurred significantly more frequently in children aged 9 years and younger than in older children and adults. An increase in the number of syllables within a word and the length of the carrier sentences, but not in morae, increased the occurrence of inaccuracies. However, the difficulty of the segments showed a complex relationship with inaccurate speech.
