Abstract
Two learning disabled and two learning-disabled attention deficit hyperactivity disordered boys participated in-group problem solving sessions to improve interactions with the attitudes toward a socially rejected autistic classmate. In class positive interactions and negative interactions served as individual baselines within a multiple baseline design with replications across the four students. Problem solving sessions increased positive interaction between each of the students and their autistic peer. Negative interactions, in contrast, did not decrease. Introduction of an interdependent classroom DRO subsequently reduced negative interactions. Weekly questionnaires revealed a positive shift in the residually autistic child's sociometric status. The number of interactions this student initiated with three peers and his responsiveness to those interactions initiated by two also increased.
