The influence of task difficulty on aberrant behavior was investigated with three severely handicapped students (10, 13, and 15 years old). Noticeably higher rates of problem behavior occurred in demand compared to no demand conditions. In addition, there were higher rates of problem behaviors on difficult versus easy tasks. (Author)

Three experiments assessed the efficacy of various reinforcers to increase correct task responding in a total of 10 autistic children, aged 6-9. Of the reinforcers used (stereotypy, delayed echolalia, perseverative behavior, and food), task performance was highest with opportunities to engage in aberrant behaviors, and lowest with edible…

Two classroom conditions (classroom demand and classroom attention) were systematically manipulated to explore their effects on performance under analogue assessments for a girl (age 7) with severe intellectual disabilities who exhibited aggressive behavior. Results demonstrated higher levels of aggression during demand analogue conditions when…

A study involving three individuals (ages 13-20) with developmental disabilities and problem behaviors examined the influential role that unanticipated idiosyncratic stimulus variables play in affecting the outcome of a functional analysis. Guidelines are discussed concerning when to suspect that idiosyncratic stimuli might be acting to influence…

Three first grade students who exhibited difficulty completing independent work improved their math performance when given recording devices to self-record performance data, with two of the children showing more reactivity when using the more obtrusive device. Three of four second grade students increased math performance during periods when peer…

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 article analyzes variables associated with adherence by parents to recommendations designed to solve common childhood problems and specific corresponding processes that are responsible for poor adherence. Adherence variables include establishing operations, stimulus generalization, response acquisition, and consequent events. (Contains…

The performance of five students (ages 6 to 10) in an adjustment class for deaf children was compared under fixed and variable ratio schedules of reinforcement. During the VR condition, students visually attended more and engaged in disruptive behavior less often than during the FR condition. (Author)
