We analyzed the inappropriate social interactions of 3 students with Asperger's syndrome whose behavior was maintained by social positive reinforcement. We tested whether inappropriate social behavior was sensitive to social positive reinforcement contingencies and whether such contingencies could be reversed to increase the probability 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…

Previous studies have shown that presession attention for problem behavior can serve as an abolishing operation when attention functions as a positive reinforcer. In the current study, we show that the stereotypy of a child with severe disabilities was undifferentiated during standard analogue functional analysis conditions. However, when…

We conducted an analogue functional analysis contrasting motor tasks with varying types of social consequences for movements associated with tardive dyskinesia (TD) in 2 men who had been diagnosed with developmental disabilities and TD. Our findings suggest that TD-related movements were not a function of social reinforcement contingencies.…

We studied whether movements associated with tardive dyskinesia (TD) served operant functions in 2 men with developmental disabilities. We found that TD-related movements occurred more frequently in the alone and attention conditions and less frequently in control and demand conditions. Our findings suggest that TD-related movements may not be…

We studied a reviewer-prompting system designed to improve the timeliness of journal reviews. The prompting system consisted of an e-mail message sent individually to reviewers noting the manuscript number, review due date, and associated social amenities for the timely completion of the task. Our results indicated that the prompting system…

Two studies involving five students (ages 9-17) with autism found that stereotypy was multiply determined or occurred across all assessment conditions (attention, demand, no-attention, and recreation conditions) and that the presumed association between response topography and behavioral function may be less important than previously realized.…

A study of three children (ages 11-13) without disabilities who served as peer supports for students with disabilities in general education classrooms found that serving as a peer support had positive academic effects on the students without disabilities. Follow-up probes demonstrated that the positive benefits regarding academic engagement…

A study of the relationship between presence or absence of sleep deprivation, allergy symptoms, and the rate and function of problem behavior in three adolescents with moderate to profound mental retardation found that problem behavior was negatively reinforced by escape from instruction, and both allergy symptoms and sleep deprivation influenced…

Four criteria for evaluating the appropriateness of units of analysis for task analytic research are proposed. Meeting all four criteria and thus recommended for use in behavior analytic work is percentage correct with competent performance coded and a task analysis grid showing individual step performance.

Four studies analyzed eye poking behavior of a youth with profound disabilities. Results demonstrated substantive reductions in the frequency of eye poking when goggles were worn and when a video game was provided as a competing source of visual stimulation and as a reinforcer. Music was less effective in reducing eye poking. (Author/DB)

Two students with severe disabilities were alternately presented with interspersed high-compliance requests and social comments as antecedents to low-compliance requests. Analysis found similar positive effects on compliance for interspersed requests and social comments. The effectiveness of social comments was related to the time interval between…

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.…

Antecedent conditions involving instructor's task demands and social comments were evaluated for three students with severe disabilities who exhibited problem behavior. An instructor emitted high rates of social comments and gradually faded in task demands. Social validity assessments indicated that substantial improvements were perceived in…

Three students (ages 17, 19, and 21) with moderate disabilities were taught to read and match-to-sample sight words comprising 4 4-member stimulus sets. Student performance indicated that symmetric relations emerged before one-node transitive relations and that one-node transitive relations emerged before two-node transitive relations. Results…
