This study replicated and extended Wright (2006) and Whitehurst, Ironsmith, and Goldfein (1974) by examining whether preschool aged children would increase their use of passive grammatical voice rather than using the more age-appropriate active grammatical construction when the former was modeled by an adult. Results showed that 5 of the 6…

Research on the effects of concurrent schedules of reinforcement during treatment of problem behavior has shown that response allocation can be biased in favor of adaptive responses by providing increased reinforcement for these responses. However, this research has focused on the effects of only two concurrently available response options. In…

We evaluated the effects of reinforcing multiple manding topographies during functional communication training (FCT) to decrease problem behavior for three preschool-age children. During Phase 1, a functional analysis identified conditions that maintained problem behavior for each child. During Phase 2, the children's parents taught them to…

Presented is a series of studies in which the efficacy of applying operant conditioning methodologies to the problem of stuttering was examined. One requirement was that the designed therapeutic programs utilize only verbal contingent stimuli (reinforcers and punishers) in the traditional therapeutic setting (client and therapist seated together…

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…

THE STUDY INVESTIGATED SOME OF THE RELATIONSHIPS BETWEEN A CHILD'S VERBAL BEHAVIOR AND ENVIRONMENTAL EVENTS NECESSARY IN ACQUIRING LANGUAGE. TWO TRAINABLE RETARDATES (FROM A GROUP OF SIX, AGED 3-6 TO 5) WITH A FUNCTIONAL VOCABULARY OF NO MORE THAN TWO OR THREE WORDS WERE SEEN INDIVIDUALLY IN 20- TO 30-MINUTE SESSIONS TWICE A WEEK DURING A 4-MONTH…

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)

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…

An institutionalized, retarded, adult male's response to verbal commands was increased through the use of positive control of a discriminative stimulus. Operant conditioning was noted as a possible means of enabling retarded individuals to acquire behaviors fundamental to a self-help repetoire. (Editor)

Delinquent and non-delinquent male adolescents were asked to give memories from their early childhoods under treatment conditions of verbal praise, attitude agreement, or objective correctness. (Author)

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…

Four selected subtests from the WISC, Arithmetic, Digit Span, Picture Arrangement and Block Design, were administered to 111 pupils in the third and fourth grades at Florida State University Elementary School. Social reinforcers, i.e., verbal approval and disapproval, were systematically presented to the examinees after specified items and between…
