I am an ecological psychologist who is interested in the temporary structure of stage actors. My research-based on ecological psychology is an embodied, situated, and non-representational approach pioneered by James J. Gibson, who is an American perceptual psychologist. I found the uniqueness of the spontaneous gesture skills of one-person play’s actors and provided a detailed description of the creation process of stage actors. Besides, I come in for interviews about how the folk performing arts are being handed down from person to person down. Extensively published in Japanese cognitive psychology journals, with related expertise in gestures of early blind people and stage actors.
