The purpose of this study was to examine the impact of play activities
, teachers' predictions of children's sociability, and intervention fi
delity variables on the level of interaction between three preschooler
s with autism and their typical peers. Children participated in daily
play activity groups of three, including one youngster with autism and
two peers. Following a baseline condition, all children in the class
learned to exchange a range of prosocial overtures, including shares,
play organizers, and assistance. Teachers then implemented an individu
al reinforcement contingency to maintain children's newly taught excha
nges. Results indicated that social reciprocity and peer effort correl
ated most highly with target children's level of social interaction. C
onversely, teachers' choice of activity materials and predictions abou
t sociability did not correlate with children's interactions during ei
ther experimental phase. These findings are discussed with regard to t
heir implications for future social skills research and intervention.
