Three studies involving four preschoolers revealed that by delaying reinforcement for verbal behavior until after the opportunity to display the corresponding behavior had occurred, correspondence behavior was made to generalize to untrained responses and to maintain overtime. (Author)

A 13-year-old who watched television excessively participated in a behavioral program featuring a token-actuated timer. Earned tokens activated the T.V. for 30-minute periods. The token-exchange system effectively reduced T.V. viewing and reductions were maintained at two followup points. (CL)

A group contingent free time procedure was effective in reducing disruptive behavior of third-grade children in math and language arts settings. (CL)

The study evaluated the effectiveness of superimposition and subsequent removal of a schedule of continuous reinforcement (CRF) as a rate-decreasing procedure in efforts to eliminate unwanted behaviors. Examination of lever-pressing patterns of eight male rats showed responding was substantially reduced during the superimposition of CRF but…

The study evaluated a commonly used component of brief time-out, in which release from time-out is delayed contingent on the occurrence of the disruption. Data were collected for one normal and two mentally retarded children on time-out producing behaviors and delay-producing behaviors during time-out. (Author/CL)

Three adolescent students with special educational needs were given reinforcers (nickels) according to three different concurrent variable-interval schedules. Time allocated to the assigned tasks was in linear relationship to the reinforcement rate. However, changes in reinforcement schedules were not followed by changes in allocation patterns…

The study evaluated the relationship between attending to task and speed of task completion of six mentally retarded adults in a vocational training program. (Author)

Four college students completed programmed instruction in a computerized format with either no delay between questions, a noncontingent delay, or a contingent delay (delay after each question answered incorrectly). Noncontingent delay produced better performance than no delay and contingent delay, because students used delay periods to study.…

Two studies measured the feasibility of DRO (differential reinforcement of other behavior) and VT (variable time) reinforcement in reducing body rocking stereotypy of institutionalized severely and profoundly retarded adults (N=2 and 5). (CL)

This study compared the effects of multiple versus single deadline contingencies on distribution of unit-mastery test taking by students in four university classes taught using the personalized system of instruction. Rate of test taking was most uniform when multiple deadlines were imposed throughout the course. (Author/DB)

Undergraduates in two experiments learned ten mathematical rules under different strategies of adapting instruction to individual needs. An adaptive model developed by Hansen was structured to use multiple predictors for two purposes: (1) to classify students into four independent learning style groups, thus allowing for group-based adaptation;…

This report summarizes the results of research studies on instructional practices that significantly affect the cognitive, language, or mental abilities of students with disabilities. The investigation reviewed current research on instruction of students with moderate disabilities and sought to identify effective instructional practices. The steps…
