Fixed-Interval Responding During Human Computer-Interactive Problem Solving

Functional Assessment and Challenging Behaviors: Some Future Directions

Behavior analysts have had a significant impact on the analysis and intervention of challenging behaviors in persons with developmental disabilities. These successes are celebrated in the first part of this article. In the remainder of the article, we present a selective discussion of three issues that we hope will help to further stimulate work with challenging behaviors: (a) the development of challenging behaviors, (b) the role of rule-governance in challenging behavior, and (c) the behavior of persons (mediators) who directly apply functional assessment and intervention technologies. Each of these issues is discussed and implications are drawn for future reseach and practice in the field. In drawing some conclusions, we focus on the internal and external validity of functional assessment and interventions.
