0-2歳における自己認知の発達

乳児・他者関係からの考察

抄録

This study examined the developmental process of self-recognition through the infant-other interaction. Detailed diary records about the author's son R and his reactions to strangers, peers and mirror images in the experimental situations were analyzed from his birth to 25 months of age. After 4.5 months, when R was watching his parents, he sometimes looked away, avoiding an eye contact. This seemed to be the budding awareness of others as different from himself. At 9-10 months, he became aware of the fact that he himself had a location in space, showing self-assertion and a beginning to understand others' intentions. From then on, he imitated others' acts and experienced that his intentions were thwarted by others, and then at about 17 months, he began to behave with an awareness of his own intention. This seemed to be the emergence of self as an active agent. It was not until at 24 months, however, that he demonstrated mirror self-recognition, and it was when he began to understand another's point of view.
