In two studies, the systematic approach to designing functional assessment-based interventions (FABIs) created by Umbreit, Ferro, Liaupsin, and Lane (2007) was used with high school students receiving special education services in self-contained classrooms reserved for students with persistent behavior problems. In Study 1, an AB design was used…

This study examined whether direct, interval-by-interval measures of treatment integrity would make it possible to distinguish whether equivocal intervention results could be attributed to the intervention itself, or to poor implementation. Josh, an eight-year-old 3rd grader, performed at or slightly above his peers' academically, yet engaged in…

It is customary in behavior analysis to distinguish between positive and negative reinforcement in terms of whether the reinforcing event involves onset or offset of a stimulus. In a previous article (Baron & Galizio, 2005), we concluded that a distinction of these terms is not only ambiguous but has little if any functional significance. Here, we…

Functional analyses of problem behavior for 4 young boys with developmental delays showed that problem behaviors were maintained by both negative and positive reinforcement. Functional communication training was conducted with one set of training stimuli in which the child's mother presented a work task in the family living room. Pretreatment…

Extinction effects were evaluated in a multiple baseline across behaviors design with 2 boys (ages 7 and 8) with disabilities after just one of several target problem behaviors was observed during a functional analysis. Other target behaviors emerged as extinction was introduced sequentially across all problem behaviors. (Contains three…
