Four levels of the behavior constraint-reinforcement variable were manipulated: attractive reward, unattractive reward, request to perform, and a no-reward control. Only the unattractive reward and request groups showed the performance decrements that suggest the overjustification effect. It is concluded that reinforcement does not cause the…

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…

The consumption of nonfood items (i. e., pica) frequently occurs in persons with developmental disabilities. Pica may result in the puncture or blockage of the digestive tract, infestation by gastrointestinal parasites, and can interfere with an individuals daily learning, occupational performance, and quality of life. Twenty-six published studies…

The emotional and behavioral problems of students in the classroom are a major concern for teachers, administrators, and the public. Without effective behavior management, a positive and productive classroom environment is impossible to achieve. Forty years of scientific research supports the efficacy of behavioral interventions in the classroom,…

Obesity prevalence has doubled among adults and overweight has tripled among children since 1980. This article discusses behavioral approaches to the obesity epidemic, focusing on recent environmental changes, the resulting behaviors, and possible solutions. Over the last 4 decades, time spent in sedentary activities, the consumption of fast food,…

When behavior suggests that the value of a reinforcer depends inversely on the value of the events that precede or follow it, the behavior has been described as a "contrast" effect. Three major forms of contrast have been studied: "incentive contrast," in which a downward (or upward) shift in the magnitude of reinforcement produces a relatively…

The matching law was used to analyze whether the proportion of shots taken from two- or three-point range would match the proportional reinforcement rates produced by those shots when the reinforcement rate of three-point shooting was changed. Rule changes in 1994 and 1997 altered the distance of the three-point line in the National Basketball…

Evidence-based practices (EBPs) are the basis on which teachers and other service providers are required to design educational programs for learners with autism spectrum disorders (ASD). As part of their work with the National Professional Development Center (NPDC) on ASD, researchers developed a process for reviewing the research literature and…

This article focuses on the use of "timeout" as a classroom behavior modification technique. The questions and guidelines are presented in a flow chart format in order to facilitate easy and quick use by practitioners. (Author)

This report reviews current literature on feedback and suggests practical implications of feedback research for educators. A definition of feedback is offered, and past definitions in prior research are noted. An analysis of the current state of knowledge of feedback discusses the historical development of feedback theory and suggests that…

Nonaversive procedures (including differential reinforcement of other behaviors, differential reinforcement of low rates of responding, differential reinforcement of alternative behavior, and stimulus control) were effective in bringing target behaviors under control for five students (14-17 years old) with autism or autistic-like behavior. (CL)

In Study 1 the aggressive behavior of a deaf/blind adolescent was eliminated through a differential reinforcement of other behavior (DRO) procedure combined with a reinforcer cueing technique and brief time-out. In Study 2 DRO reduced stereotypic eye-pressing by a young blind hearing-impaired child. (Author/CL)

The Good Behavior Game was modified to include a token reinforcement system (Good Behavior Game Plus Merit). It proved successful in reducing disruptive behavior and improving assignment completion in two students designated as high-risk for placement in a behaviorally impaired classroom. General Acceptability and uses of the intervention are…
