To identify the most potent reinforcers for 10 young children with attention deficit hyperactivity disorder, the relative treatment utility of a verbal forced-choice questionnaire, child nomination, and direct observation was evaluated. Results demonstrated that all three methods were more likely to disagree than agree and that a forced-choice…

Five children with autism participated in learning sessions involving trials of an acquisition task interspersed with trials of three maintenance tasks. Correct responses to acquisition tasks were continuously reinforced throughout all conditions; reinforcement for competent performance of maintenance tasks differed systematically. All children…

The behavior of special education students (age 12 and 16) was evaluated as they were presented with 2 academic response alternatives on concurrent reinforcement schedules. Both subjects allocated higher rates of responses to the richer schedule of reinforcement, although only 1 responded exclusively to the richer schedule. (Author/JDD)

This study compared the effects of unequal and equal reinforcer duration during a functional analysis of aberrant behavior in an 11-year old with moderate mental retardation. Results showed that reinforcer duration affects the rate of aberrant behavior and may potentially alter functional analysis interpretation. (DB)

Noncontingent reinforcement (NCR) was applied to reduce the destructive behaviors of five-year-old quadruplets diagnosed with mental retardation and pervasive developmental disorder. Findings suggest that the effectiveness of NCR may be dependent on the use of a dense schedule of reinforcement initially and that systematic fading can increase the…

This study found that use of music as a reinforcer was highly effective in increasing productive and decreasing nonproductive behavior of 6 competitive swimmers (ages 12-16) during the dry-land portion of a practice session. Subjects rated the musical reinforcement favorably and elected to have the procedure continued. (Author/DB)

Three studies investigated environmental correlates of self-injurious behavior in seven developmentally disabled children and adolescents which were then later used for treatment. Correlates investigated included positive reinforcement, negative reinforcement, automatic reinforcement, and control. "Escape extinction" was successfully…

The study evaluated the effects of a time-efficient reinforcer assessment package with three preschoolers with autism. Systematic assessment of children's reinforcers for correct responding virtually eliminated nontargeted maladaptive behaviors, and yielded expected improvements in accuracy. (Author/DB)

The field of behavior analysis has not learned how to develop interventions that rely on positive reinforcement for all participants, including the normal adults who implement them. Thus, the field has not learned how to avoid evoking countercontrol. Establishment of collaborative relationships with the people targeted for help is suggested. (JDD)

Five adult males with profound retardation were assessed on a motor task during baseline, satiation, and deprivation conditions, with three classes of consequences: small food items, music, and social praise. Each stimulus class functioned as reinforcement, with different degrees of effectiveness during satiation versus deprivation conditions.…

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.…

This study found that, compared to measuring approach behaviors to a variety of stimuli, a forced-choice stimulus preference assessment used with four young children with severe mental retardation resulted in greater differentiation among stimuli and better predicted which stimuli would result in higher levels of responding when presented…

A choice assessment was used to categorize reinforcers as high, middle, and low preference with 4 males (ages 7 to 19) with multiple disabilities including severe/profound mental retardation. High-preference stimuli consistently functioned as reinforcers for all subjects whereas low-preference stimuli did not function as reinforcers. (Author/DB)

This study compared three methods of stimulus preference assessment for four verbal children (ages six to nine) with attention deficit hyperactivity disorder, specifically evaluating the utility of a verbal choice procedure for assessing relative reinforcer value. Verbal and pictorial stimulus-choice assessments identified high- and low-preference…

This study compared selection of a preferred reinforcing stimulus just prior to a training session by either the trainer or subject with profound developmental disabilities. Results obtained with four adult subjects indicated little or no difference in reinforcement effects when reinforcing stimuli were selected by subjects rather than trainers.…
