Activity Theory
In this chapter I will give an account of some ideas in the Russian Theory of Activity or Activity Theory (AT) that have influenced the Activity Domain Theory (ADT): activity, mediation, and meaning. The activity domain in ADT is a direct descendant from “activity” in AT, while “mediation” and “meaning” are necessary prerequisites for the activity modalities construct in ADT. The AT was an attempt to apply the ideas of Marx and Engels to psychology in the early decades of the new socialist state, the Soviet Union. The front figure in this pioneering movement was the Russian psychologist and semiotician L. S. Vygotsky (1896-1934) together with his collaborators A. N. Leont’ev (1903-1979) and A. R. Luria (1902-1977). Other prominent researchers in this spirit were V. N. Vološinov (1895-1936) and M. M. Bakhtin (1895-1975). With the advent of the Stalinist era the momentum of the AT was more or less crushed. However, small but marginalized groups kept the ideas of AT alive. One of the most prominent philosophers was the previously mentioned E. Ilyenkov (1924-1979). During the last couple of decades, AT has gained a renewed momentum among Western researchers and been further developed by the works of M. Cole, J. Wertsch and Y. Engeström and others.
