Thumbsucking of a girl aged 2 years and 9 months was recorded by the parents during three 10-minute reading baselines. In Study 1, thumbsucking was punished by contingent termination and resumption of reading. In Study ii, positive reinforcement was provided for other (non-thumbsucking) behavior. The results imply that parents can effectively…

This paper describes a project of Communidad Los Horcones (Mexico), dealing with alternatives to contrived or artificial reinforcement. The paper proposes the use of natural reinforcement, which can be individualized and received without the mediation of another person and which contributes to making the natural consequences of behavior…

This commentary on EC 603 646, a paper describing a natural reinforcement project of Communidad Los Horcones (Mexico), argues that natural reinforcement is best when the learning objective produces a natural reinforcer and when the natural reinforcer is more powerful than any competing punishers inherent in the task or reinforcers for competing…

The paper describes the use of an operant procedure to assess the speech perception of 11 young (7 to 35 months old) hearing impaired children and 11 normally hearing subjects. Subjects were presented with a repeating background stimulus and conditioned to turn their head on presentation of a contrasting syllable. The head-turning responses were…

In a study of behavior modification two Down's syndrome preschool children, the first a 5-year-old boy with autistic behavior patterns and the second a 4-year-old girl whose behavior problem was to reject other children, were examined. The first S was engaged in ball catching activities with a teacher with positive reinforcement (playing the S's…

Three hypotheses were tested in this 6-week study: a) training in systematic application of strategies designed to reinforce desirable pupil behavior would enable the teacher to develop and maintain classroom control and increase pupil learning; b) desirable pupil behavior thus produced could be transferred from one classroom to another in which…

Compared in a junior high class of 12 educable mentally handicapped children were the effects on adaptive behaviors of a token reinforcement program involving only positive reinforcement and a token reinforcement program additionally involving response cost. The token reinforcement response cost condition allowed students to earn points for…

Two experiments using paraprofessional personnel were conducted to determine effectiveness of a schoolwide token system on academic performance of trainable mentally retarded (TMR) children. The first experiment consisted of 42 TMRs in a 6-week summer program, in which reading, writing, and arithmetic were the behaviors studied. Pretest and…

Three studies were conducted to compare standard instruction with reinforcement programs for the trainable mentally retarded (TMR). In the first study, 24 TMRs were matched into two groups, with one group participating in a 6-week academic program having token reinforcement and the other group continuing in a standard teaching program. Statistical…

A study was conducted using positive reinforcement to increase and maintain the time spent participating in study behavior of a six-year-old female kindergarten student and to introduce the teacher to behavioral change techniques. Attending and non-attending study behaviors were observed during 30-minute independent study periods in the classroom.…

Inappropriate mealtime behaviors of a blind, mentally retarded, behaviorally disordered 10-year-old were modified via behavior therapy techniques, including audiotape of favorite stories turned off during inappropriate behavior and praise (plus access to food) for appropriate napkin and utensil use, once desired sitting posture had been…
