Data on the social behavior of typical children may inform practitione
rs and researchers regarding the appropriate goals of intervention for
children with autism. This study assessed the ongoing levels of natur
ally occurring social behavior in 64 preschool-aged children. A 2 x 2
factorial design was used to analyze population (children with autism
and typical children) and age (3 years 3 months vs. 4 years 4 months)
differences at the time of preschool entry. Predictable population dif
ferences were found for key social behaviors of proximity to children,
social bids from children, and focus of engagement on children, as we
ll as for behavioral context variables of verbalizations, adult focus,
and atypical behaviors. No differences were found in the amount of ti
me spent focused on toys or objects. There were also no differences in
the presenting behaviors of younger and older children with autism. R
esults are discussed in terms of implications for establishing early s
ocial intervention goals.
