The principle of motivation has resurfaced as an independent variable in the field of behavior analysis over the past 20 years. The increased interest is the result of the refinements of the concept of the motivating operation and its application to the learning needs of persons with developmental disabilities. Notwithstanding the increased…

Discusses behavioral momentum and the general behavioral relation between the persistence of behavior and the rate of reinforcement obtained in a given situation. Strategies for establishing the generality of behavioral relations are reviewed, followed by a brief summary of evidence for the generality of behavioral momentum. (Author/CR)

Reviews laboratory research on behavioral momentum conducted with pigeons and summarizes its findings and their generality to people, including those with mental retardation. Discusses the high-probability procedure used to establish compliance in clinical settings and based in part on an extension of the momentum metaphor. (CR)

This commentary discusses John Nevin's article on establishing compliance via behavioral momentum involving high-probability procedures, and questions whether applications of behavioral momentum can be derived from the theory, whether applications could have been developed if the theory not been formulated, and whether the theory will add…

A functional analysis involving antecedent events was conducted with four students identified as having behavior problems. Off-task behavior was measured while task difficulty and level of adult attention was manipulated during analog sessions. Results revealed higher rates of off-task behavior during difficult tasks and improved behavior when…

The thesis is presented that a "family compromise" and "family members' definitions of the situation" refer to different phenomena, and that in some families, there is a great discrepancy between the beliefs of individual family members and that which has been called the "family mind." (Author)

This paper reviews evidence of the success of behavior intervention approaches which teach students with challenging behaviors alternative functional communication behaviors. Research supporting the view that challenging behavior is a form of nonverbal communication is reviewed, noting the importance of identifying what such individuals are…
