The study evaluated the effects of a time-efficient reinforcer assessment package with three preschoolers with autism. Systematic assessment of children's reinforcers for correct responding virtually eliminated nontargeted maladaptive behaviors, and yielded expected improvements in accuracy. (Author/DB)

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)

Symptoms of hyperactivity and possible relationships of condition to various hereditary and physical factors are examined. Various methods of dealing with the problem are presented, and the need to provide hyperactive children with appropriate outlets of activity is emphasized. (RW)

This model has derived a particular set of competencies by selecting the best features of the disciplinarian, behavioristic, and therapeutic approaches to classroom management; each approach contains an outstanding feature that contributes significantly to the eclectic model. (JD)

Three individuals with multiple severe disabilities were taught an appropriate response to problem behaviors, but the response was less efficient than the problem behavior on physical effort, schedule of reinforcement, or stimulus-reinforcer time delay. The response did not compete successfully with the problem behaviors until a new, more…
