Unified psychology.

The authors describe an approach to psychology they refer to as unified psychology, which is the multiparadigmatic, multidisciplinary, and integrated study of psychological phenomena through converging operations. In this article, they unpack this definition and explore some of its implications. First, they review some previous efforts to conceive of a unified psychology and consider objections to such an undertaking. Second, they discuss the importance of converging operations for psychology. Third, they consider the need for multidisciplinary and integrated study of psychological phenomena that focuses on the phenomena rather than on particular lines of disciplinary inquiry. Fourth, they ponder the problem of investigators' becoming locked into a single paradigm with its attendant set of presuppositions about psychological theory and research. Fifth, they outline some possible objections to their proposal and respond to them. Finally, they discuss some implications of their views.
