Abstract
In a day-care program for pre-school children with developmental disabilities, choice-making opportunities were provided in the following settings; snack, individual's task, and educational materials. Next, choice-making opportunities were systematically incorporated in a play activity program. Prior to providing choice-making opportunities, children had experienced six kinds of play activities. Then children could choose a picture card among three, which illustrated each activity tool, and go to each activity room. Almost all children could express play-activity preferences through the procedures. The results are discussed in terms of choice-making function as social behavior.
