An exploration of the regression concept historically and conceptually reveals that its familiarity and frequent use have resulted in decreasing conceptual clarity and precision. Rooted in an outmoded fixation-regression model of development and psychopathology, the concept has become concretized. This paper is a beginning exploration of problematic aspects of the concept of regression, with emphasis on potentially detrimental consequences for psychoanalytic technique that derive from its unexamined use. Some of the salient issues are illustrated with clinical examples.
