Sensitivity theory divides the causes of challenging behavior into three categories, aberrant contingencies, aberrant environments, and aberrant motivation. This paper replies to criticism that sensitivity theory is circular and unsupported by empirical evidence by reporting on studies that support the theory and rejecting the idea that…

This study examined how 3 students (ages 14-18, with emotional or behavioral disorders) allocated their responding across 2 concurrently available tasks associated with unequal rates and equal versus unequal qualities of reinforcement. It found that time allocated to concurrent response alternatives was approximately proportional to obtained…

The effects of social interaction skill interventions on the social behavior of four preschool children with behavioral handicaps were evaluated. Findings indicated unique effects for social skills training and contingency management intervention. Results are discussed in relation to the role of reciprocal interaction and behavioral trapping for…

This study observed a classroom of 15 students (ages 3 to 11) with behavior disorders, using amount of teacher attention to generate hypotheses about problem behavior function which were then validated in individual functional assessments. For 14 of the students, accurate hypotheses were efficiently generated by noting how teachers distributed…

A comprehensive evidence-based treatment for substance abuse and other associated problems (Family Behavior Therapy) is described, including its application to both adolescents and adults across a wide range of clinical contexts (i.e., criminal justice, child welfare). Relevant to practitioners and applied clinical researchers, topic areas include…

This paper summarizes brief functional assessments of 79 cases of people with developmental disabilities and self-injurious, aggressive, stereotypic, or other aberrant behavior. Outcomes were evaluated across three variables: (1) referring topography, (2) control over behavior, and (3) the identified maintaining conditions for aberrant behavior.…

This study investigated the relationship between self-restraint (e.g., entanglement of limbs in clothing or furniture) and self-injurious behavior (SIB) using functional analysis with five males with severe mental retardation. Results suggested that self-restraint, like SIB, may be maintained by idiosyncratic contingencies. (Author/DB)

The effects of a warning procedure signaling exclusionary timeout as a consequence for inappropriate behavior during contingent observation timeout was evaluated with nine elementary students having emotional and behavioral disorders. The use of warnings was associated with a decrease in appropriate contingent observation timeout behaviors,…
