| Outline of Final Research Achievements |
The aim of our study was to explore how language development is promoted by hierarchy and intention sharing. As for the hierarchy, we found that infants are already sensitive to fundamental sound units and their combinations. As for intention sharing, the use of finger-pointing and eye gaze can promote relevant intention sharing through the examination of finger movement and eye-gaze coordination. As for the integration of hierarchy and intention sharing, we found that the interpretation of the hierarchical structure of phrases promotes intonation patterns that reflect the speaker’s intention. We also explored the relationship between the development of the theory of mind and complement structures and found that the ability to guess others’ intentions is related to the use of complement structures. We successfully drew the integration of hierarchy and intention sharing from developmental perspectives.
