Restricted and repetitive behavior (RRB) is more pervasive, prevalent, frequent, and severe in individuals with autism spectrum disorders (ASDs) than in their typical peers. One subtype of RRB is restricted interests in items or activities, which is evident in the manner in which individuals engage with items (e.g., repetitious wheel spinning),…

Curricula for students with autism do not take into account levels of learning such as behavioral fluency. Behavioral fluency addresses accuracy as well as speed of response. We posit that fluency increases the functionality of skills for students with autism and should be systematically programmed into a curriculum. To discuss the application of…

This study, based on observation of 28 children with autism in an integrated preschool, explored whether differing levels of autistic behavior were associated with the presence of nondisabled children or with the presence of other children with autism. Results indicated significantly decreased levels of autistic behavior corresponding to the close…

Functional analysis of the aggressive behavior of 2 boys (ages 10 and 12) with autism involved 20 brief functional assessment trials in the classroom under 3 conditions. Results showed a clear pattern in each child's aggressive behavior and suggested logical intervention strategies. The discrete-trial approach presented a practical, ecologically…

Two children (ages seven and eight) with autism and moderate mental retardation, who engaged in stereotypic behavior, were studied to investigate the effects of social interaction with peers. Results found that when peers made social initiations and the children engaged in social interaction, collateral decreases occurred in their stereotypic…
