The growing impact of feminist scholarship, activism, and politics would benefit substantially from input by radical behaviorists. The feminist community, broadly defined, and radical behaviorists share interesting commonalities that suggest a potentially fruitful alliance. There are, however, points of divergence that must be addressed; most prominently, the construct of personal agency. A behavioral reconstruction of personal agency is offered to deal with the invisible contingencies leading to gender-asymmetric interpretive repertoires. The benefits of a mutually informing fusion are discussed.Key words: feminist theory, gender, person-situation dualism, agency, invisible contingencies, interpretive repertoires, verbal communitiesIn her book Mismeasure of Woman, Carol Tavris (1992) documents the often-cited work of Samuel Cartwright, a noted American physician who in the early 1 800s studied and described a mental illness that was prevalent among slaves. He named this condition Drapetomania. The interesting thing about this condition was that it was diagnosed by a single symptom, namely, the uncontrollable tendency to run away from slavery (pp. 176-177). Could we write fiction to be this interesting? Alas, Cartwright pathologized the reasonable response of the slave, and in so doing, left the institution of slavery unexamined. Tavris goes on to show, as others have, how psychological science has historically followed a similar approach in its construction of woman and gender.The feminist critique of science came to my attention several years ago as I began to explore disciplinary frontiers in order to develop a new elective This article is a revised version of an invited address presented at the 23rd annual meeting of the Association for Behavior Analysis, Chicago, May 1997.I thank Guillermo V.

As a behavior analyst teaching undergraduates in a liberal arts institution, I realized that some of my most engaging intellectual conversations were with feminist colleagues from disciplines other than psychology. I decided to focus on the existing feminist psychological literature and eventually developed a course I entitled "Women: Psychology's Challenge."As I explored the feminist psychological literature, particularly its critique of traditional psychological science, I realized two things. First, and I felt very enthusiastic about this point, the feminist critique of traditional psychological science was, in some ways, remarkably consistent with the radical behaviorist critique.The second point was distressing yet ironically familiar. Radical behaviorism, the philosophy of science articulated by Skinner and the conceptual framework for behavior analysis, was amon...
