This bridge study evaluated the effects of contingency-specifying instructions (CSIs) and incomplete instructions (IIs) in terms of establishing instructional control of appropriate behavior. Results suggested that instructional control and maintenance were achieved with CSIs but not with IIs. Results are discussed in terms of the potential use of…

The matching law was used to analyze whether the proportion of shots taken from two- or three-point range would match the proportional reinforcement rates produced by those shots when the reinforcement rate of three-point shooting was changed. Rule changes in 1994 and 1997 altered the distance of the three-point line in the National Basketball…

To identify the most potent reinforcers for 10 young children with attention deficit hyperactivity disorder, the relative treatment utility of a verbal forced-choice questionnaire, child nomination, and direct observation was evaluated. Results demonstrated that all three methods were more likely to disagree than agree and that a forced-choice…

A study examined the effects of a behavioral intervention and methylphenidate on inappropriate behavior and sleep disturbance displayed by a 6-year-old boy who had been diagnosed with attention deficit hyperactivity disorder. Results showed the behavior intervention was effective in reducing inappropriate behaviors regardless of the presence or…

This study examined the outcomes of a competing activities intervention to decrease skin picking exhibited by a 9-year-old student with comorbid diagnoses. Results of an ABCBAB design revealed that the use of student-selected manipulatives resulted in reduced skin picking. (Contains 1 figure.)

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…

This study compared three methods of stimulus preference assessment for four verbal children (ages six to nine) with attention deficit hyperactivity disorder, specifically evaluating the utility of a verbal choice procedure for assessing relative reinforcer value. Verbal and pictorial stimulus-choice assessments identified high- and low-preference…

A functional analysis isolated peer attention as the primary maintaining variable for disruptive behavior by a student (age 8) with attention deficit hyperactivity disorders. Using a brief reversal design, noncontingent reinforcement was then shown to reduce disruptive behavior related to the peer attention condition. (Contains three references.)…

A urine alarm, typically used to treat nocturnal enuresis, was effectively used to treat diurnal enuresis in a 15-year-old female with depression, attention deficit hyperactivity disorder, and conduct disorder. The study indicated that the alarm eliminated wetting in both treatment phases and that continence was maintained at three-month and…

A study evaluated the utility of classroom-based functional and adjunctive assessments of problem behaviors for two adolescents with attention deficit hyperactivity disorder and comorbid oppositional defiant disorder. Classroom interventions derived from information obtained during assessments resulted in reductions in problem behaviors. Teacher…

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…

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…

Double-blind placebo-controlled procedures examined whether 6 children with attention deficit hyperactivity disorder could recognize medication effects. Three children were able to accurately report their medication status at levels greater than chance. Accuracy of reports was related to dosage level, differences in behaviors, and the presence of…

This paper summarizes basic research on response effort in diverse applied areas including deceleration of aberrant behavior, attention deficit-hyperactivity disorder, oral habits, littering, and problem solving. The paper concludes that response effort as an independent variable has potent effects, and research exploring the applied benefits of…
