Developmental understanding of self-body representation from the aspect of multimodality integration

点击翻译按钮获取中文摘要

Self-body representation consists of multimodal information, such as visual, somatosensory, and verbal modalities. In this study, we examined how do young children integrate information from these modalities each other and construct body representation. After hearing a story including an unfamiliar word of body part, they were tested whether or not they can identify the correspondent body parts using a mirror reflection. The performance of identification of body part was improved. These results suggest that verbal categorization of body parts contributed to integrate between visual and somatosensory body-representation.
