| Research Abstract |
Aims oft s research were to :
(1)Extend the previous research much empirical way, and,
(2)Submit a new theoretical perspective based on dynamical systems.
To these ends, we created a new experimental environment called Double TV environment that can control temporal aspect of infant-mother interaction. Using this environment we conducted a series of experiments comparing EEG activities between Delayed- interaction and Live-interaction. The result suggested that infant brain responds stronger to non-contingent (Delayed) interactions than normal (Live) ones. Especially the parietal and posterior temporal regions at both hemispheres were more active during Delayed interaction. As for the theoretical issue, we conducted computer simulations about turn-taking, two-arm movement, dynamic categorization based on dynamical systems approach. All research conducted during this project were published or submitted to international journals and conferences. We believe that our work can contribute to the future of cognitive science and interaction study.
