The present investigation compared the effects of reinforcing compliance with either positive or negative reinforcement for a participant who displayed escape-maintained problem behavior. The results indicated that positive reinforcement in the form of a highly preferred edible or leisure item produced higher levels of compliance and lower levels…

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…

A discrete trials, operant tracking and a descending series procedure for the determination of hearing levels with three profoundly retarded young adults previously diagnosed as untestable proved quite workable and may provide for improved hearing testing with "difficult to test" individuals.

Conditions associated with the maintenance of hand mouthing were studied in 3 experiments with 12 adults with profound mental retardation. Functional analysis of hand mouthing, reinforcers, and preference for hand-toy versus mouth-toy contact were assessed. Hand stimulation was the predominant reinforcer for all participants. (SW)

This study examined whether problem behaviors of three adults with profound mental retardation, which had been maintained by continuous reinforcement schedules, could be extinguished more rapidly than those maintained on an intermittent schedule of reinforcement. No significant differences in extinction rate were found between the two conditions.…

Evaluation of reductive treatment versus instructional treatments on the generalized reduction of problem behaviors in two adolescents with severe intellectual disabilities indicated that when only one member of a response class was blocked, a collateral increase in other problem behaviors was observed, but learning an alternative positive…

Two classroom conditions (classroom demand and classroom attention) were systematically manipulated to explore their effects on performance under analogue assessments for a girl (age 7) with severe intellectual disabilities who exhibited aggressive behavior. Results demonstrated higher levels of aggression during demand analogue conditions when…

This study compared the effectiveness of differential negative reinforcement of other behavior (DNRO) and alternative behavior (DNRA) for reducing self-injurious tantrums maintained by escape from demands in a 4-year-old girl with severe retardation. Both DNRO and DNRA reduced self-injury and increased independent task performance, with DNRA…

A functional assessment of tantrum behaviors of two students (ages seven and nine) with severe mental retardation found that the function of the behavior was to gain attention rather than to avoid or escape demands. Intervention, based on the positive reinforcement hypothesis, resulted in a substantial reduction of tantrums for both subjects.…

Five experiments with severely retarded noncompliant males made use of behavioral momentum to increase compliance. A series of commands with which the subject was very likely to comply were issued immediately prior to issuing a low-probability command. Results indicated increased compliance and decreased compliance latency and task duration.…

A behavioral assessment procedure was evaluated with five children with severe/profound mental retardation who exhibited feeding problems of limited intake. Subjects were fed various types of foods. Results indicated each subject fit into one of four categories: (1) total food refusal, (2) food type selectivity, (3) food texture selectivity, or…

A study examined the relationship between neutralizing routines and problem behavior in three adolescents with severe intellectual disabilities. Functional analyses found the problem behaviors were motivated by either escape or tangible items. Results found that neutralizing routines were effective in reducing self-injurious behavior and…

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…

Concerns about noncontingent reinforcement (NCR) are illustrated in a case study of a 13-year-old girl with severe mental retardation who was demonstrating severe aggression. Her NCR treatment produced an extinction burst and incidental reinforcement. A brief omission contingency was added to the reinforcement schedule, which resulted in decreased…

Functional analysis of the self-injurious behavior (SIB) of three individuals with profound mental retardation indicated the behavior was maintained by negative reinforcement (escape from instructional situations). Stimulus fading was applied. Results indicated that instructional fading virtually eliminated SIB, but these effects were not…
