Brief experimental analysis (BEA) is a useful tool for quickly evaluating intervention strategies for individuals with academic deficits and minor behavior problems. However, there is a lack of research investigating BEA for intervention strategies with individuals who emit severe problem behavior to avoid academic demands. For the current study,…

Pigeons were trained in three experiments with a two-key, concurrent-chains choice procedure. The initial links were equal variable-interval schedules, and the terminal links were random-time schedules with equal average interreinforcement intervals. Across the three experiments, the pigeons either stayed in a terminal link until a reinforcer was…

Functional assessment is redefining the standards for clinical interventions with problem behavior and reemphasizing the importance of basic behavioral mechanisms. It has shown the importance of complex patterns of behavioral control, functional assessment as an ongoing process, and the importance of attention to antecedent variables. Future…

Sensitivity to reinforcement contingencies was examined in six individuals with mental retardation using a concurrent operants procedure in the context of a computer game. Results included individual differences in sensitivity and differential sensitivity to rate and magnitude variation. Results suggest that comprehensive assessments of potential…

Seven parents conducted assessments in an outpatient clinic using a prescribed hierarchy of antecedent and consequence treatment components for their children's problem behavior. Brief assessment of potential treatment components identified variables controlling children's appropriate behavior. Experimental control was achieved for six of the…

This commentary summarizes methodological and conceptual issues in functional analysis methodologies and offers some suggestions for their resolution. Considered are increasing complexity, absence of contingencies during assessment, use of subtle manipulations, alternative assessment strategies, analysis of antecedent influences on behavior,…

This study examined how reinforcer rate, quality, delay, and response effort combined to influence the choices of six adolescents with emotional disturbance and learning difficulties and the feasibility of an assessment methodology based on matching theory for determining differential responsiveness to reinforcer and response dimensions. Results…

In order to examine the effectiveness of a token economy program, sheltered workshop attendance of chronic schizophrenics was investigated under the following conditions: response cost versus no response cost consequences for nonattendance; response cost and noncontingent token payment; and restricted versus unrestricted mobility during the no…

This study, an approach to controlling "acting-out" behaviors of handicapped children in elementary schools, describes the use of a home-based dependent group contingency to eliminate the destructive behavior (fire-setting, vandalizing property) of a mildly retarded eight-year-old boy. (Author/PN)
