Abstract
This case study was conducted to identify the characteristics of the interaction between infants with developmental disorders in inclusive day care centers and typical peers and teachers. A survey through behavior observation was conducted on the infants with development disabilities at three inclusive day care centers in Tokyo, Japan based on the Behavior Setting Theory, which is one of the major theories in Environmental Psychology, and the results were analyzed with a focus set on the subjects′ social interaction. In the analysis, the subjects were categorized into different types by purpose of interaction, method of expression, and subjects/objects of behavioral motivation, while the characteristics of subjects′ interactive behaviors were analyzed.
