The authors believe that the future of psychology lies in a unification of enhancement and reinforcement, not in the wasted energy of continued conflict. (Author)

This article discusses problems inherent in the analysis of automatically reinforced behaviors, which are behaviors that are maintained by operant mechanisms independent of the social environment. Four classes of treatment that are compatible with automatic reinforcement are reviewed, including manipulations of establishing operations, sensory…

The sunk cost effect is the increased tendency to persist in an endeavor once an investment of money, effort, or time has been made. To date, humans are the only animal in which this effect has been observed unambiguously. We developed a behavior-analytic model of the sunk cost effect to explore the potential for this behavior in pigeons as well…

Four rats responded under a "self-control" procedure designed to obtain delay- discount functions within sessions. Each session consisted of seven blocks, with seven trials within each block. Each block consisted of two initial forced- choice trials followed by five free-choice trials. On choice trials, the rats could press either of two…

Behavioral pharmacology is a maturing science that has made significant contributions to the study of drug effects on behavior, especially in the domain of drug-behavior interactions. Less appreciated is that research in behavioral pharmacology can have, and has had, implications for the experimental analysis of behavior, especially its…

Based on a doctoral dissertation presented by the first-named author in partial fulfillment of the requirements for the Ph.D. degree under the supervision of the second-named author

THE LINC COMPUTER PROVIDES A PARTICULAR SCHEDULE OF REINFORCEMENT FOR BEHAVIORAL EXPERIMENTS BY EXECUTING A SEQUENCE OF COMPUTER OPERATIONS IN CONJUNCTION WITH A SPECIALLY DESIGNED INTERFACE. THE INTERFACE IS THE MEANS OF COMMUNICATION BETWEEN THE EXPERIMENTAL CHAMBER AND THE COMPUTER. THE PROGRAM AND INTERFACE OF AN EXPERIMENT INVOLVING A PIGEON…

Forty-eight preschool children were run under a classical conditioning paradigm in which some neutral stimuli were repeatedly associated with an adult matching the behavior of the subject, and other neutral stimuli were associated with the same adult mismatching the behavior of the subject. Preference for the stimuli associated with being matched…

The article reviews behavioral intervention research with the handicapped, focusing on the analysis of subject, setting, and procedural factors that influence the outcome of behavior modification. Behavior enhancement procedures (e.g., tactile and sensory reinforcement, contracting, and modeling) and behavior reduction procedures (e.g., extinction…

Study investigated the effects of a response-produced intense-noise stimulus (punishment) on the extinction of children's hitting behavior. (Author)

The use of music to bring out constructive behavior in emotionally upset individuals is discussed. (CK)

Using Ss high or low on a social desirability scale, a verbal conditioning attempt was made to alter the relative frequency of self referent statements that were either positive or negative. (Author)
