Vocal stereotypy is a commonly occurring challenging behavior in children with autism spectrum disorder (ASD) that is frequently maintained by automatic reinforcement and often interferes with skill acquisition. Matched stimulation (MS), and response interruption and redirection (RIRD) are two interventions that have been demonstrated to be…

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…

We used a multiple baseline design across participants to determine if teacher greetings would reduce the latency to task engagement. Three participants were identified by their respective teachers as having difficulty initiating task-appropriate engagement at the beginning of class. Latency was measured from teacher greeting until the participant…

Differential reinforcement of alternative behavior (DRA) is used frequently as a treatment for problem behavior. Previous studies on treatment integrity failures during DRA suggest that the intervention is robust, but research has not yet investigated the effects of different types of integrity failures. We examined the effects of two types of…

The purpose of this study was to examine the use of percentile schedules as a method of quantifying the shaping procedure in an educational setting. We compared duration of task engagement during baseline measurements for 4 students to duration of task engagement during a percentile schedule. As a secondary purpose, we examined the influence on…

Two experiments analyzed the single-alternative form of the matching law as a description of student behavior. Four students (ages 8-10) exhibiting off-task behavior were exposed to variable-interval schedules of social reinforcement contingent on academic engagement. Results provided evidence that subject behavior was under control of the…

A multiple baseline design across participants was used to determine how teacher greetings affected on-task behavior of 3 middle school students with problem behaviors. Momentary time sampling was used to measure on-task behavior during the first 10 min of class. Teacher greetings produced increases in students' on-task behavior from a mean of 45%…

The effects of variable-interval (VI) and fixed-ratio (FR) schedules of reinforcement for work-related behavior and an organizer for the work materials (behavioral prosthesis) were evaluated with 3 adults with severe or profound mental retardation. The participants had been recommended for study because of high rates of off-task and aberrant…

This study examined the effects of methylphenidate drug therapy and differential reinforcement on the disruptive behavior and task engagement of 3 children (ages 6 through 11) with mental retardation. Results indicated that both interventions were effective for two of the children. No evidence of an additive or synergistic effects of the two…

Off-task and disruptive behavior in two fifth graders decreased rapidly during an intervention in which, working in dyads, they served either as peer monitors or point earners. Peer-monitor and point-earner roles, when alternated on an every-other-day basis, were equally effective in reducing inappropriate behavior. (Author/JW)

A self-management intervention package was used with preschoolers with developmental delays. Self-assessment of performance resulted in increases in active engagement across all participants during training, but generalization to classrooms was sporadic and short-lived. When recruitment of teachers' contingent praise was added, treatment effects…

Two elementary school students with emotional/behavioral challenges increased task engagement and reduced disruptive behavior when allowed to choose academic tasks. The effects of choice making were distinguished from preference, by yoking a no-choice phase to a previous choice-making condition; the yoked control phase was inferior to the…

This study found that, in a task context, differential reinforcement of other behavior (DRO) effectively reduced problem behavior and increased task performance of 2 adolescents with severe disabilities (ages 15 and 19), whereas a time-out procedure was ineffective. In a leisure context, time-out was effective while DRO was ineffective.…

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…

This study implemented a physical education curriculum focusing on positive social skills in two urban elementary schools. Results showed an immediate increase in student leadership and independent conflict resolution, increased class time devoted to activity participation, and decreased time spent off task or on organizational tasks. Similar…
