BIOLOGY AND BEHAVIOR - A SET-POINT HYPOTHESIS OF PSYCHOLOGICAL FUNCTIONING

This article provides a broad overview of an exploratory thesis designed to enhance an understanding of perturbations and rigidities of psychological functioning - a set-point hypothesis of psychological functioning. Historical precedents and parallels with Keesey's set-point theory of obesity are offered. Basic tenets of the hypothesis are detailed, and relevance to clinical behavioral theory is outlined. It is concluded that the set-point hypothesis may provide a framework for conceptualizing clinical cases and optimizing interventions. The thesis appears to be testable; however, the articulation of specific methodologies and research designs must be undertaken before the ultimate usefulness of the set-point hypothesis can be determined.
