The delivery of food contingent on 10 s of consecutive toy engagement resulted in a decrease in engagement and a corresponding increase in other responses that had been previously reinforced with food. Similar effects were not observed when tokens exchangeable for the same food were delivered, suggesting that engagement was disrupted by the…

This study examined how 3 students (ages 14-18, with emotional or behavioral disorders) allocated their responding across 2 concurrently available tasks associated with unequal rates and equal versus unequal qualities of reinforcement. It found that time allocated to concurrent response alternatives was approximately proportional to obtained…

We manipulated two parameters of response blocking to reduce pica: (a) the criteria for initiating the procedure (either earlier or later in the response chain) and (b) the distance from which the procedure was initiated. Results suggested that response blocking may be effective only when implemented early in the chain and with near-perfect…

Basic and applied research on variables that influence the extinction of operant behaviors is reviewed and applied to the treatment of behavior disorders. The potential value of a general technology for the use of behavioral extinction is discussed. The paper concludes that current research findings are not sufficient for the development of a…

This study analyzed specific stimuli reinforcing destructive behavior in two 11-year-olds males with mental retardation and severe destructive behavior problems maintained by attention. The use of concurrent schedules of reinforcement identified alternatives to the reinforcing verbal reprimands and led to development of effective treatments to…

Dimensions characteristically descriptive of applied behavior analysis over the past 20 years are explored: applied, behavioral, analytic, conceptual, technological, effective, and capable of appropriately generalized outcomes. Effectiveness in the future must take into account cost-benefit ratios, social validity assessments, and the need for…

This paper summarizes brief functional assessments of 79 cases of people with developmental disabilities and self-injurious, aggressive, stereotypic, or other aberrant behavior. Outcomes were evaluated across three variables: (1) referring topography, (2) control over behavior, and (3) the identified maintaining conditions for aberrant behavior.…

This study investigated the relationship between self-restraint (e.g., entanglement of limbs in clothing or furniture) and self-injurious behavior (SIB) using functional analysis with five males with severe mental retardation. Results suggested that self-restraint, like SIB, may be maintained by idiosyncratic contingencies. (Author/DB)

Following an initial school inservice workshop on functional assessment and differential reinforcement procedures with five children having severe behavior problems, on-site technical assistance was provided to local school personnel working in transdisciplinary teams. Functional analysis was effective in identifying individual maintaining…

The study investigated the relationship between topographically different child behaviors (compliance and inappropriate activities) in four mentally retarded subjects (aged 3-5) by using a methodology that tests for response covariation. Regardless of the intervention used, the behavior targeted, or the direction manipulated, the nontargeted…

This study evaluated self-control and impulsivity in two nine-year- old males with severe developmental disabilities and behavior disorders. Functional analyses suggested that aggression was reinforced by food access. A differential reinforcement procedure to reinforce appropriate mands was implemented. Although aggression occurred when it…

The study examined the extent to which momentary DRO (differential reinforcement of other behavior) maintained suppression (following initial treatment with whole-interval DRO) of the maladaptive behavior of nine severely multihandicapped elementary aged students. Results indicated that momentary DRO maintained response suppression comparable to…
