The delivery of food contingent on 10 s of consecutive toy engagement resulted in a decrease in engagement and a corresponding increase in other responses that had been previously reinforced with food. Similar effects were not observed when tokens exchangeable for the same food were delivered, suggesting that engagement was disrupted by the…

Results and a case study for a DBT-enhanced habit reversal treatment (HRT) for adult trichotillomania (TTM) (Keuthen & Sprich, 2012) is adapted for use with adolescents. Trichotillomania in adolescence is a very important but understudied problem. Onset often occurs in adolescence, and yet very little treatment research exists. DBT-enhanced habit…

Self-injurious behavior (SIB), such as self-biting and head banging, has been reported to occur in approximately 10% of captive, individually housed nonhuman primates. Accounts of the etiology of SIB in primates range from ecological to physiological. However, to date, no research has examined the possible influence of social consequences…

Within the context of behavioral economics, the ratio of response requirements to reinforcer magnitude is called "unit price." In this investigation, we yoked increases in reinforcer magnitude with increases in intervals of differential reinforcement of other behavior (DRO) to thin DRO intervals to a terminal value. (Contains 1 figure.)

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…
