We combined several single-subject designs to assess the effects of contingent and noncontingent token reinforcement on moderate-to-vigorous physical activity (MVPA) exhibited by 4 preschool-aged children. Higher overall levels and longer bouts of MVPA reliably occurred when tokens were delivered contingent on MVPA for 3 of the 4 children when…

The Good Behavior Game (GBG) is an effective intervention to reduce disruptive behavior. The GBG typically involves immediate stimulus presentation (e.g., delivery of a token) following disruptions; however, experimenters have also removed tokens contingent upon disruptions. In the present study, we compared the effects of the GBG-stimulus…

A study examined the effects of a combined education and token system intervention to improve adherence to inhaled corticosteroids for an 8-year-old girl and a 10-year-old boy with asthma. A withdrawal design demonstrated improved adherence and, for one child, an associated improvement in pulmonary function occurred. (Author/CR)

A study examined sensitivity to reinforcement in two boys (ages 7-10) with attention deficit hyperactivity using the matching law and evaluated effects of methylphenidate. In the medicated condition, the matching function for both subjects resulted in higher asymptotic values, indicating an overall elevation of behavior rate under these…

A study conducted reinforcer assessments for three boys (ages 7-9) with attention deficit hyperactivity disorder who alternately received either a placebo or methylphenidate. Methylphenidate altered the relative reinforcing effectiveness of various stimuli that are often used in classroom-based behavioral treatment programs, particularly coupons…
