The sense of subjectivity is the feeling that you are the person (subject) who is doing the act, not anyone else.This sense of subjectivity is not always conscious, but it is felt in all the actions we perform on a daily basis.In particular, the utterances that are important for communication are the movements of the throat and mouth, and the voices that are uttered can make you feel your own personality.What role does the personality of the voice play in the feeling that you are speaking?

　The research group explored the characteristics of the sense of subjectivity that accompanies utterances through two psychological experiments that examine the relationship between utterances and the voices that are heard in response.In the first experiment, in a situation where the sense of subjectivity is strongly felt, the sense of subjectivity is measured using the effect that the time interval between the action and the result is felt short (intensive binding effect). In the second experiment, we asked the same participants to directly evaluate the sense of subjectivity that they felt when speaking.As a result, it was shown that listening to one's own voice as a result of speech act is indispensable for obtaining a strong sense of independence.

　This time, I highlighted the close connection between the sense of subjectivity that accompanies the act of speech and the voice that is heard at that time.Based on this result, it is expected to elucidate the mechanism of hallucination, which is one of the typical symptoms of schizophrenia, and to contribute to next-generation communication through virtual avatars in virtual space, which has been attracting attention in recent years. It is said that.
