Proposes a minimal set of principles based on short-term and long-term memory mechanisms that can explain the major static and dynamic properties of operant behavior in both single-choice and multiresponse situations. The model predicts the major qualitative features of operant phenomena and suggests an experimental test of theoretical predictions…

The ability of a reinforcer to maintain behavior decreases as a hyperbolic function of its delay. This discounted value can help explain impulsivity defined as the choice of an immediate, small reinforcer over a delayed, large reinforcer. Human operant studies using consumable reinforcers such as videos have found impulsivity with delays under 1…

A guest editorial comments on the acrimonious rhetoric and arguments exhibited in the debate over the use of aversives with individuals with mental retardation. The editorial urges members of the field to refocus their framing of the issues around respect for persons, beneficence, and justice. (JDD)

Treatment of behavioral problems of 3 girls (ages 31-37 months) with Rett's disorder is discussed. Behavioral treatment using operant conditioning principles did little to alter the course of the disorder for these individuals. The one consistent improvement for the girls was a decrease in tantrums. (SW)

To date, only 1 study has evaluated the impact of a Pavlovian drug conditional stimulus (CS) on operant responding. A within-subject operant 1-lever go/no-go (across sessions) design was used to evaluate the impact of Pavlovian contingencies on the discriminative stimulus effects of nicotine (0.4 mg/kg) and ethanol (800 mg/kg) in male Sprague…

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)

By watching and responding to the way a shill answered "yes-no" questions about food items, a developmentally delayed preschool boy greatly improved over his poor base-line "yes-no" answers to these same items. He was also able to give correct answers subsequently during generalization probe sessions. (PS)

Used modified differential reinforcement of other behavior schedule with exclusionary time-out procedure to treat 69-year-old aggressive male patient. Results showed clear demonstration of behavioral control and clinically significant treatment effects during experimental periods. (Author/NB)

A correspondence training procedure was used to develop consistency between children's verbalizations and subsequent behavior across increasingly remote settings and time. Generalization was obtained in the absence of any salient externally imposed contingencies after Ss had reliably come under control of verbalizations about preschool behaviors.…

The purpose of this paper is to examine, from a sociopsychological standpoint, some of the elements which account for the success of behavior therapy and to comment on the meaning of its emergence in modern society. Behavior therapy is seen as an indicator and consequence of major cultural trends. (Author/CG)

An empirically developed infant and preschool reinforcement survey was completed by 35 parents and 21 children. Test-retest coefficients were computed on these data after a one-week interval. The development of the survey, as well as its usefulness for school psychologists, is described. Survey is appended. (Author)

Classical conditioning is responsible for students' positive and negative feelings, whether directed toward subject matter, peers, teachers, or education in general. This article explains how educators can use classical conditioning principles (such as reinforcement, extinction, and paired stimuli) to create an anxiety-free learning environment.…

This response to a paper by Guess and Carr (EC 602 212) on stereotypy and self-injurious behavior in the disabled focuses on (1) potentially misleading statements that may discourage practitioners from operant approaches to stereotypy and self-injury, and (2) strengths and weaknesses of the model compared to existing operant models.

Five adolescents with autism, 5 control participants, and 4 child controls received rewards for varying their sequences of responses while playing a computer game. In preceding and following phases, rewards were provided at approximately the same rate but were independent of variability. When reinforced, variability increased significantly in all…
