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…

This study examined the effectiveness of using qualitatively different reinforcers to teach self-control to an adolescent boy who had been diagnosed with an intellectual disability. First, he was instructed to engage in an activity without programmed reinforcement. Next, he was instructed to engage in the activity under a two-choice fixed-duration…

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…

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…

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…

The effects of long and short durations of positive practice overcorrection were studied with one moderately retarded and four severely retarded children (10 to 13 years old). The short and long practice durations (30 seconds and three minutes) produced equally rapid reduction of off-task behavior and acquisition of correct object placement…

A study involving an elementary student with learning disabilities evaluated the effectiveness of a high-probability request sequence on compliance to a request for completion of a math assignment. High probability requests were effective in reducing the latency to compliance but only minimally affected duration of engagement. (Contains five…

Brief multiple-stimulus-without-replacement (MSWO) preference assessments were conducted with 3 adolescent boys with emotional-behavioral disorders in the context of their public school educational program. The reinforcing effects of stimuli identified as high, medium, and low preference were then evaluated using an alternating treatments design…

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)

Functional communication training, extinction, and response chaining decreased escape-maintained aberrant behavior and increased task participation of 3 youth, ages 10 through 15, with moderate mental retardation, 2 of whom also had autism. Task escape was contingent on verbally responding and completing task steps. Behavior chaining also…

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.…

Prompting, positive and negative reinforcement, and a gradually extended reinforcement schedule were used with three autistic clients (two six-year-olds and one adolescent) to teach them to maintain on-task behaviors without constant supervision. Results indicated that appropriate behavior could be successfully maintained with only infrequent and…
