Effects of Reinforcer Quality on Behavioral Momentum: Coordinated Applied and Basic Research

The high-probability (high-p) instructional sequence has been an effective treatment for noncompliance. However, treatment failures have also been reported. We hypothesized that the efficacy of the high-p treatment may be improved by using higher quality reinforcers for compliance to high-p instructions. The resistance of compliance to change was tested by varying reinforcer quality in two applied studies and a basic laboratory experiment. Experiment 1 tested the hypothesis that an increase in reinforcer quality for high-p compliance will increase the effectiveness of the high-p treatment when it fails to increase compliance. Experiment 2 assessed the effects of reinforcer quality on resistance of compliance to change by presenting successive low-p requests following the high-p treatment. A basic laboratory study (Experiment 3) was conducted to further isolate the relation between reinforcer quality and behavioral momentum. Two different liquid reinforcers (sucrose and citric acid solutions) were presented in a two-component multiple variable-interval variable-interval schedule followed by a single extinction test session. Results of all three experiments showed a generally consistent relationship between reinforcer quality and behavioral momentum

The Momentum of Human Behavior in a Natural Setting

Adults with mental retardation in a group home received popcorn or coffee reinforcers for sorting plastic dinnerware. In Part 1 of the experiment, reinforcers were dispensed according to a variable-interval 60-s schedule for sorting dinnerware of one color and according to a variable-interval 240-s schedule for sorting dinnerware of a different color in successive components of a multiple schedule. Sorting rates were similar in baseline, but when a video program was shown concurrently, sorting of dinnerware was more resistant to distraction when correlated with a higher rate of reinforcement. In Part 2 of the experiment, popcorn or coffee reinforcers were contingent upon sorting both colors of dinnerware according to variable-interval 60-s schedules, but additional reinforcers were given independently of sorting according to a variable-time 30-s schedule during one dinnerware-color component. Baseline sorting rate was lower but resistance to distraction by the video program was greater in the component with additional variable-time reinforcers. These results demonstrate that resistance to distraction depends on the rate of reinforcers obtained in the presence of component stimuli but is independent of baseline response rates and response-reinforcer contingencies. Moreover, these results are similar to those obtained in laboratory studies with pigeons, demonstrating that the determination of resistance to change by stimulus-reinforcer relations is not confined to controlled laboratory settings or unique to the pigeon

Clinical applications of behavioral momentum

An important measure of the validity and utility of basic behavioral research is the extent to which it can be applied in real life. Basic research on behavioral momentum and the model unifying choice and resistance to change (Nevin & Grace 1999) has stimulated the development of behavioral technologies aimed at increasing the persistence of adaptive behavior and decreasing maladaptive choices

A Comparison of Exclusion Time-Out and Contingent Observation for Reducing Severe Disruptive Behavior in a 7 Year Old Boy

This study compared the effectiveness of exclusion time-out and contingent observation for reducing the severe disruptive behavior of a child with developmental disabilities. Interventions were employed in a classroom by a special education teacher and a teacher\u27s aide. Procedural and functional integrity measures for the two interventions indicated that the treatments were implemented in an optimal manner. The results showed that both time-out procedures reduced disruption to very low levels and were not found to be differentially effective. The theoretical and practical significance of this finding are discussed

Acquisition and Maintenance of Exercise Skills under Normalized Conditions by Adults with Moderate and Severe Mental Retardation

Three older adults with severe and moderate mental retardation were taught a complete regimen of aerobic-type exercises under conditions that approximated mainstream exercise programs. A treatment package (prompts, contingent praise, and delayed reinforcing activities) was implemented by individual coaches while participants followed the instructions of an exercise leader. Prompts were faded and contingent activities were discontinued following skill acquisition. All participants correctly performed between 63% and 85% of the exercise repetitions during training and between 82% and 95% at a 9-month follow-up. Issues and strategies for achieving integration of persons with mental retardation into mainstream leisure activities were discussed

Theories of Reactivity in Self-Monitoring: A Comparison of Cognitive-Behavioral and Operant Models

Three theoretical explanations have been proposed to account for reactivity in self-monitoring, including Kanfer\u27s cognitive-mediational model, Rachlin\u27s operant recording response model, and Nelson and Hayes\u27s multiple cueing models. The present study compared these models under uniform conditions. Sixty undergraduates were assigned to either self-monitoring (SM); SM plus goal setting (GS); SM, GS, plus self-reinforcement (SR); GS plus SR; or a training only control group. The dependent variable consisted of verbal nonfluencies. Results suggested that although all conditions produced significant reductions in verbal nonfluencies, reactive effects were largest under the two conditions that employed self-reinforcement conditions (i.e., SM + GS + SR, and GS + SR). The role of external contingencies in the reactivity of self-monitoring are discussed
