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)…

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…

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…

The effectiveness of positive and negative evaluative comments for children's learning was assessed in a two-choice discrimination task. Results indicate that negative comments after incorrect responses greatly facilitated learning while positive comments after correct responses had little effect. To explain the findings, a naturalistic analysis…

The results of a group of studies, the objective of which was to clarify the conditions that account for the effectiveness of verbal approbation, are reported. Among the most significant findings were: (1) that the reinforcement properties of verbal approval are susceptible to distortion, misinterpretation or enhancement and must be applied in a…

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…

In this article, the author shares an anecdote demonstrating one-trial learning which is commonplace in human behavior. The demonstration suggests that under some conditions, when people hear someone speak, their behavior changes, even in the absence of an apparent contingency of reinforcement, but only if they have in their repertoire verbal…

An experiement was conducted to test the hypothesis that interest inventory items would function as reinforcing stimuli in a visual discrimination task. When previously rated liked and disliked items from the Strong Vocational Interest Blank were differentially presented following one of two responses, subjects learned to respond to the stimulus…

This study undertook to reconcile the views of cognitive and behavioral learning theorists on the issue whether learning without awareness (LWA) is possible, and if so, the circumstances under which it occurs. In Study One, two reinforcement procedures were compared in a structured verbal conditioning task. Study Two was a replication of Study…

Five experiments were conducted to determine whether properties inherent in some training procedures may subtly influence the adaptability of skilled performance of complex tasks. The first two experiments assessed the insensitivity of low-rate performances. Examined in the third experiment was the issue of whether instructions that focus…

Describes a study to develop and cross validate a verbal measure of information rate. This measure should be helpful in assessing the information rate of situations, whether the situations are described verbally, presented pictorally or with audiovisual recordings, or experienced directly by subjects.

Designed for both parents and teachers, the handbook presents methods for educating the moderately and severely retarded child. Those methods include measuring progress, rewarding and punishing, ways of using rewards and punishers, ways of giving positive reinforcers and punishers, withholding reinforcers (extinction), letting the child reward…

TO STUDY THE EFFECTS OF OVERTRAINING ON REVERSAL AND NONREVERSAL SHIFTS OF CUES, 96 NORMAL (MEAN AGE = 117 MONTHS, MEAN IQ = 109.8) AND 96 RETARDED CHILDREN (MEAN AGE = 119 MONTHS, MEAN IQ = 70.1) WERE TESTED ON A SIMULTANEOUS 2-CHOICE DISCRIMINATION TASK. SUBJECTS WERE TRAINED ON TWO LEVELS (CRITERION AND OVERTRAINING). FOLLOWING TRAINING ON THE…
