We compared rates of academic responses and problem behavior during mathematics with distributed and accumulated reinforcer arrangements for 3 students with Attention-Deficit Hyperactivity Disorder who engaged in chronic, severe problem behavior. All 3 students engaged in more academic responding and less problem behavior when reinforcers…

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…

Top-ranked items were identified during 30-min free-operant preference assessments for 9 individuals. Data from each session were analyzed to identify the item (a) that was engaged with first in each session and (b) to which the most responding was allocated after 5 min, 10 min, 15 min, 20 min, and 25 min had elapsed in each session. The results…

The present experiment extended and replicated the use of functional analysis and a peer-mediated intervention to decrease disruptive behavior displayed by children diagnosed with attention deficit hyperactivity disorder in an afterschool program. After determining that the participants displayed off-task behavior maintained by peer attention via…

Comparative studies of forward and backward chaining have led some to suggest that sensitivity to each teaching procedure may be idiosyncratic across learners and tasks. The purposes of the current study were threefold. First, we assessed differential sensitivity to each chaining procedure within children when presented with multiple learning…

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…

We manipulated relative reinforcement for problem behavior and appropriate behavior using differential reinforcement of alternative behavior (DRA) without an extinction component. Seven children with developmental disabilities participated. We manipulated duration (Experiment 1), quality (Experiment 2), delay (Experiment 3), or a combination of…

Three participants whose problem behavior was maintained by contingent attention were exposed to 45-min presessions in which attention was withheld, provided on a fixed-time (FT) 15-s schedule, or provided on an FT 120-s schedule. Following each presession, participants were then tested in a 15-min session similar to the social attention condition…

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…

Previous research suggests that motivating operation (MO) manipulations may assist in assessing discriminated manding (Gutierrez et al., 2007). The current study partially replicated and extended previous research by varying access to concurrently available reinforcers with different preference values (i.e., MO manipulations). Manding did not…

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 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…

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.)…
