This study found that, in a task context, differential reinforcement of other behavior (DRO) effectively reduced problem behavior and increased task performance of 2 adolescents with severe disabilities (ages 15 and 19), whereas a time-out procedure was ineffective. In a leisure context, time-out was effective while DRO was ineffective.…

This response to four papers on the nature of reinforcement focuses on the implications for application of theory to practice. The response addresses: reversibility of single-incentive selective associations; response deprivation, reinforcement, and economics; the substitutability of reinforcers; and delay reduction. (DB)

A 10-year-old autistic child was trained to imitate verbal prompts describing the child's motor responses. When intervention was introduced in the form of a gradual delay in the presentation of the verbal prompts, the child's spontaneous speech on trained items increased. Generalization and maintenance were analyzed. (Author/JDD)

A classwide peer tutoring procedure was implemented in an urban elementary school classroom of 23 students, to improve students' spelling performance. Results indicated the untrained or collateral tutoring behaviors increased the academic response frequencies of three tutees and the weekly spelling achievement of one target tutee. (Author/DB)

Five students, aged 10-11, with serious emotional disturbances and/or learning disabilities, recorded their attentive behavior and academic productivity. Then performance was assessed under a choice condition, the treatment program was faded, and maintenance was probed. Results revealed that both treatments produced and maintained improvements in…

A time delay procedure was used to teach three children (ages 5-9) with autism to ask the question "What's that?" when novel stimuli were presented, and generalization of the skill was assessed. Results suggest that children with autism can be taught to ask questions that lead to acquisition of new information. (Author/DB)

A computer-assisted instruction program was used to teach spelling words to 5 learning-disabled or educable mentally handicapped students (ages 11-12) using a time delay procedure; manage content presentation based on individual student responding; and collect performance data. Four students learned the words, though maintenance varied.…

Parents of three autistic boys (ages 7-8) were taught to use a time delay procedure to increase their children's appropriate spontaneous speech in naturally occurring daily settings. Results indicated that all children increased their daily spontaneous speech and generalized their speech to other locations and persons. (Author/JDD)

Ten staff members of residential facilities for individuals with mental retardation were trained in self-monitoring procedures, to increase staff on-task behavior and adherence to scheduled activities. Increases in both on-schedule and on-task behavior resulted, and generalization to evening hours occurred. Supervisor feedback was subsequently…
