This study examined the longitudinal change in the play durations of nine children with autism spectrum disorders and the effect of joint attention strategies of adults. Observations were conducted in the first 10-minute free-play situations of the 50-minute intervention sessions (11~19 sessions for each child) held nearly every weekend for six months. The play durations with a toy in last two sessions were longer than the ones in first two sessions. Then, a positive correlation was examined on the play durations in last two sessions and the number of "high-level receptions" (the children followed adult suggestion and started playing with a new toy). And when the adults switched the attention of children to new toys or plays following children's interests, "high-level receptions" were frequently elicited. These results suggest that the joint attention strategies following children's interests might facilitate children's engagement in play.
