A commonly associated side effect of extinction as a treatment for behavior disorders is an initial increased frequency of the target response, called an "extinction burst." This study analyzed 113 sets of extinction data and found that extinction bursting occurred in only 24% of cases and was less common when extinction was combined…

The assessment of generalization has become a priority of applied behavior analysis. The study provided a thorough assessement of the generality of a comprehensive self-control intervention designed to increase the math performance of an underachieving student in a regular elementary school classroom.

This study examined whether problem behaviors of three adults with profound mental retardation, which had been maintained by continuous reinforcement schedules, could be extinguished more rapidly than those maintained on an intermittent schedule of reinforcement. No significant differences in extinction rate were found between the two conditions.…

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…

After finding that self-injurious behavior in two young males with developmental disabilities was negatively reinforced by escape from instructional activities, an intervention provided noncontingent escape on a fixed schedule and differential negative reinforcement of other behavior. Provision of escape, even when noncontingent, resulted in…

Using an ABAB design, two procedures for requesting a change of activity were compared for their effect on the stereotypic behavior of a man with autism. One procedure requested immediate change of activities, whereas the second procedure gave advance notice of a change. Less stereotypy occurred when advance notice of change was given. (Author/DB)

A review of the January 1993 issue of the "Journal of the Experimental Analysis of Behavior" concludes that behavioral interventions produce collateral effects, but predicting those effects in applied work is complicated because of verbal and instructional influences and because of interactions among reinforcer types.

This commentary outlines considerations in assessing (and programing for) social validity to attain results that are valued by client audiences. It discusses the objectives and contexts of several types of social validation, procedures for conducting a social validation, and questions addressed by researchers in assessing social validity.

The field of behavior analysis has not learned how to develop interventions that rely on positive reinforcement for all participants, including the normal adults who implement them. Thus, the field has not learned how to avoid evoking countercontrol. Establishment of collaborative relationships with the people targeted for help is suggested. (JDD)

A functional assessment of tantrum behaviors of two students (ages seven and nine) with severe mental retardation found that the function of the behavior was to gain attention rather than to avoid or escape demands. Intervention, based on the positive reinforcement hypothesis, resulted in a substantial reduction of tantrums for both subjects.…

Obscene verbalizations in an individual with traumatic brain injury were treated using stimulus fading as the singular form of intervention. Results of a functional assessment revealed the obscenity was maintained by negative reinforcement. Stimulus fading (the gradual reintroduction of instructional demands) produced immediate and substantial…

Antecedent conditions involving instructor's task demands and social comments were evaluated for three students with severe disabilities who exhibited problem behavior. An instructor emitted high rates of social comments and gradually faded in task demands. Social validity assessments indicated that substantial improvements were perceived in…

This essay discusses the significance functional analysis has had for applied behavior analysis of aberrant behavior. The methodology has lessened the field's reliance on default technologies and promoted analysis of environment-behavior interactions maintaining target responses as the basis for selecting treatments. It has also contributed to the…

Teachers of 2 children (ages 7 and 13) with autism were trained to conduct a descriptive analysis and a classroom experimental analysis of aberrant behavior. Each procedure identified negative reinforcement as a maintaining variable for aberrant behavior. Intervention based on the assessment was successfully implemented with one child and had…

Issues that impact on the ability of behaviorists to be effective in solving social and community problems are discussed, including use of legislative initiatives to bring about behavior change, sustaining interventions with local resources, and the possible rewards from employing collaborative methods in behavioral research.
