Summary
Hypotheses:
1. Preschool children with autism spectrum disorders (ASDs) who undergo ABA treatment only
will demonstrate significantly better outcomes compared to an age and severity matched
control group without ABA treatment.
2. Preschool children with ASDs who undergo ABA in combination with risperidone will
demonstrate significantly better outcomes compared to age and severity matched children
who are receiving ABA alone.
3. Young age, cognitive development and attentional abilities at baseline will be
predictive of good socio-emotional and neuropsychological outcomes after ABA treatment.
4. At baseline, children with ASDs will show significantly lower performances on measures
of cognitive, neuropsychological, and socio-emotional functioning than age-matched
typically developing controls.
