Outline of Final Research Achievements |
Our visual system can recognize a variety of socially relevant information from point-light bodily movements known as biological motion (BM). However, the theoretical background remains unclear. In the first study of this project, we proposed a two-process model of the developmental mechanisms underlying BM processing. In the first system, the ‘Step Detector,’ we hypothesize that the system rapidly processes the local foot motion and feet-below-the-body information specific to vertebrates. Moreover, the system is less dependent on postnatal learning and involves subcortical networks. In the second system, the ‘Bodily Action Evaluator,’ slowly processes the fine global structure-from-motion, is specific to conspecific. Moreover, the system is dependent on the gradual learning process in cortical networks. In the second study of this project, we explored neural mechanisms underlying the processing of ostensive gestures by measuring EEGs from nine-month-old infants.

Academic Significance and Societal Importance of the Research Achievements |
本研究は、顔・視線知覚に関する研究に比して遅れている「他者の動き知覚の発達メカニズム」に関する理論整備を行った。本研究プロジェクトでは、これまで顔・視線で提案されている2プロセスモデルを下敷きとして、バイオロジカルモーション(BM)知覚発達に関する理論モデルを構築した。これにより、これまでのBM知覚処理に関する知見を説明する理論的枠組を提案することが可能となり、当該領域をさらに発展させたと考える。また、本研究成果は非定型発達児のBM知覚処理の非定型性について新たな仮説を提唱することが期待される。
