displays the percentage of 10-s intervals containing stereotypy and appropriate play across all phases of the study
for Ashley (top panel), Vince (middle panel) and Colt (bottom panel). Overall, the three participants engaged in more
appropriate play and less stereotypy following behavioral play intervention than in the initial baseline. Additionally, play
skills occurred in the absence of the teacher and eventually generalized across settings (i.e., from main classroom to therapy
room) and across sets of toys. These behavior changes were maintained at four, six, and eight weeks post intervention.
