This study of four children (ages 4-5) with emotional and behavioral disorders demonstrated that high-probability requests delivered in a variant sequence were more effective than those delivered in an invariant sequence. Children were able to act as change agents by delivering the high-probability sequences. (Author/CR)

High-probability requests were used to increase responsiveness to low-probability requests to initiate social interactions in three young boys with severe disabilities who were severely socially withdrawn. Increases were also found in unprompted social initiations and generalizations to a nontraining setting. Maintenance after training was also…

A review of the literature and descriptive examples of peers implementing the "high probability request" (HPR) strategy for changing behavior in young children with behavior disorders are presented. HPR intervention involves delivering three to five high probability requests with positive reinforcement in rapid succession, followed by a…

Behavioral momentum or interspersed requesting has been effectively used to achieve compliance with young children with disabilities. This paper reviews research on behavioral momentum and proposes expanding the utility of behavioral momentum to incorporate a variety of outcomes in social interactions, communication, motor skills, self-help…
