In the following paper, two experiments are reported based on the relation between adult approvals as conditioned reinforcers and the number of vocal verbal operants, specifically tacts, mands, wh questions, sequelics, and conversational units emitted by children diagnosed with developmental disabilities. In Experiment I, following an experimental…

The discrimination of the onset of joint control is an important interpretive tool in explaining matching behavior and other complex phenomena, but the difficulty of getting experimental control of all relevant variables stands in the way of a definitive experiment. The studies in the present issue of "The Analysis of Verbal Behavior" illustrate…

Some 80, white, schizophrenic patients were administered the Taylor Personality Scale of Manifest Anxiety (MAS), the Maudsley Personality Inventory (MPI) and were tested on an operant conditioning task. Hypotheses tested were: (1) effectiveness of social reinforcement (verbal approval) on a verbal conditioning task would be enhanced by subjecting…

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)

Eight- and 9-year-olds (N=56) were studied to determine the degree to which counterconditioning could alter the positive or negative value acquired by a neutral stimulus in a conditioning situation. Dependent measures used to assess the effects of conditioning were found to have no independent effect on subsequent evaluations of the once-neutral…

A major concern of this report was to compare the effect of three verbal reinforcement combinations (VRCs) on the rate at which children learn a simultaneous two-choice discrimination problem. The experiments were designed to test the following: (1) whether relative effectiveness of the VRCs was dependent upon task complexity or subject age; (2)…

The purpose of the current investigation was to quantify the quality of various verbal items on a college population that was voluntarily involved in remedial training in the basic academic skills. (Author)

Seventy-two sixth graders, stratified on the basis of sex and two levels of IQ (high and low) were randomly assigned to one of three treatment groups: (1) Group I (success only); (2) Group II (failure only); and (3) Group III (success and failure). These subjects (Ss) were used to investigate the effects of verbally controlled success and failure…

Results indicated that verb emission increased significantly across time for experimental group subjects as compared with control groups subjects when the operant level procedure was omitted. (Author)

One hundred twenty-eight preschool boys were subjects in a 4x2x2 factorial design to investigate the change in reinforcer efficacy as a function of prior stimulus exposure. The factors were: (1) amount of repetition, 5, 25, 45, or 65; (2) reinforcer, good or bell; and (3) satiator, good or bell. Two additional groups were run as control groups to…

Following nine hours of training in behavioral psychology, the faculty members of an 800 pupil elementary school were applying operant techniques with no further apparent need of consultation with the instructors. Twenty-two teachers were enrolled in an inservice training course entitled "Behavior Modification Procedures for the Elementary…

One control group and eight experimental groups, each composed of 12 first grade children, participated in this experiment. It was designed to investigate the effects of frequency of reinforcement and repeated evaluation of stimuli on the conditioning of preferences. Each child participated in the experiment for seven consecutive school days. The…

This is a bibliography of 81 papers and books published in the years 1957-1970 relevant to the subject of verbally-elicited responses that are in accordance with principles of classical conditioning. Of these publications, 24 are by Staats--one of the bibliographers--and his associates. (MF)
