New, unsubstantiated therapies for individuals diagnosed with autism spectrum disorder (ASD) that lack empirical support for their effectiveness seem to be introduced almost daily. These unproven therapies should be subjected to the methods of applied behavior analysis to experimentally evaluate their effectiveness. This study provides an…

Teachers of students with chronic challenging behaviors need relief, and they need it quickly. While they may appreciate the sympathy of others, what they really need is some genuine help. Challenging children can make a teacher's day difficult. In this article, the authors share some strategies that can provide "emergency relief" to…

The out-of-seat behavior of a highly disruptive 4 year old with severe disabilities was substantially reduced using differential reinforcement of incompatible behavior. The boy's in-seat behavior expanded from less than a minute to 20 minutes. The providers' use of physical restraint decreased to near-zero levels, and the boy's appropriate toy…

Behavior analysts have spent relatively little time in designing interventions to enhance motor development in typically developing infants and children. This study examines the effect of a motor training package consisting of opportunity to respond and practice (standing the infant and letting her hold the fingers of the experimenter),…
