Soviet activity theory, largely developed by A. N. Leont'ev, can be seen as a European complement of American I/O psychology and an important current of action theories in general. This paper identifies the major strength of Leont'ev's theory as the bridging potential it achieves by situating activity between each of several major pairs of opposite poles: mind and matter or body (exemplified by thinking workers and their work tasks), subject and object, understanding and explanation, theory and practice, humanist psychology and behaviourism. Some implications of activity theory and its bridging potential are pursued in the contexts of I/O theory-construction and research methods, and in the substantive problem areas of job design, job analysis, organization development, and personnel training.
An Overview of Activity TheoryTHE PRIMACY OF ACTIVITY "Die Tat ist alles -The deed is everything," wrote Johann Wolfgang Goethe in Faust, Part 2. For Martin Heidegger, the major problem of Western philosophy since Plato seems to have been the exclusive focus on abstractions and theory which obscure the practical activity and pre-theoretical knowledge out of which concepts and categories really evolve in the first place. G. W. F. Hegel moved away from static essences to dynamic processes, an orientation which greatly influenced die action-and revolution-oriented Karl Marx. In America, pragmatism is the philosophical school of diought most immediately associated with a focus on "the deed," on the Greek pragma ("act," "business"). Skinner (1989) reminded us that "to define" once meant "to mark the bounds or ends," dial "to distinguish" was originally "to mark something by pricking it," and that "to determine" meant "to locate die end of somediing."
