| Outline of Final Research Achievements |
In the dialogue among mother tongue adult speakers, overlapping utterances are produced in transition-relevance places (TRP). This phenomenon seems to appear as the result of some capability which reduces the mental ‘burden’ of the dialogue in the mother tongue. We examined the age to acquire this capability regarding Japanese mother tongue speakers.
The timing of the turn taking of the mother tongue and the non-mother tongue speakers was compared first. It was found that the non-mother tongue speaker could not maintain TRP. Next, the timing of turn taking between adults and five-year olds or six-year olds was examined. As for five-year olds, a difference between them and adults was present, but a difference between six-year olds and adults was absent. As a result, it found that the capability was already acquired by six.
