This study asked whether the concurrent reinforcement of behavioral variability facilitates learning to emit a difficult target response. Sixty students repeatedly pressed sequences of keys, with an originally infrequently occurring target sequence consistently being followed by positive feedback. Three conditions differed in the feedback given to…

Initial experiment demonstrated operant acquisition of an instrumental hand-pulling response in 4-8-month-old infants; the effect achieved with contingent, noncontingent, delayed reinforcement, and the suppression, recovery, and facilitation effects of noncontingent stimulation are discussed.

Study was designed to investigate the effects of signalled non-contingent reward on the operant behaviour of human subjects. (Authors)

The present study attempted to duplicate earlier findings and to investigate the effects of mechanical as well as personal reinforcement. However, the acquisition and extinction differences between oral and anal scoring types reported in the earlier studies were not obtained with either personal or mechanical reinforcement. (Author)

This project examined whether a history of reinforced relational responding would result in derived requesting skills in 3 adults with disabilities. Participants were first taught to request preferred items using pictures; they were then taught conditional discriminations between pictures and their dictated names and between dictated names and…

AN ELECTRONIC SYSTEM OF SMALL TRANSCEIVER UNITS, PACKAGED IN A BELT WORN BY STUDENTS IN CLASS, WAS DESIGNED TO TRANSMIT LIGHT SIGNALS AND VIBRA-TACTILE CODED MESSAGES BETWEEN STUDENTS AND A COUNSELOR AT A CLINIC SCHOOL. FOUR MALE ADOLESCENTS SELECTED FOR LOW MOTIVATION, AGGRESSIVE CLASSROOM BEHAVIOR, AND HIGH PEER-GROUP RATING REPORTED THEIR TIME…

Based upon the author's doctoral dissertation (University of Minnesota, 1967).

Response and reinforcement features of operant discrimination paradigms used in audiometric assessment were investigated with normal 17-month-old children. Findings indicated more responses prior to onset of habituation when response tasks involved complex central processing skills and a twofold increase in number of subject responses when…

Article reviews evidence on the effects of contrast and matching, that these effects are related, and that both effects are reactions to the same independent variable. (Author/RK)

The major concern of the study was to determine what differences, if any, in independent reading-work behaviors were observed between baseline and experimental conditions using the Rules, Ignore, Praise technique with two seven year old children. During the reinforcement period children worked harder. Bibliography. (Author/AF)

From its inception in the 1930s until very recent times, the cumulative recorder was the most widely used measurement instrument in the experimental analysis of behavior. It was an essential instrument in the discovery and analysis of schedules of reinforcement, providing the first real-time analysis of operant response rates and patterns. This…

The present experiments investigated the effects of several classical conditioning manipulations on the performance of young children in an instrumental discrimination learning situation. Two predictions from general conditioning-extinction theory were tested: (1) acquisition of an instrumental response to a stimulus for a positive reinforcer in a…

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…

The relation between the rate of a response ("B") and the rate of its reinforcement ("R") is well known to be approximately hyperbolic: B = kR/(R + R[subscript o]), where k represents the maximum response rate, and R[subscript o] indicates the rate of reinforcers that will engender a response rate equal to half its maximum value. A review of data…

Assesses a self-reward contracting procedure intended to facilitate completion of self-administered desensitization. Self-referred snake phobics received either (a) self-administered desensitization; (b) self-administered desensitization with self-reward contracting; or (c) a self-administered placebo with self-reward contracting. Results show the…
