Controversy and Growth Points in the Activity Theory in Psychology

Activity theory is the most powerful and influential current of Russian psychology in the world today. It considers the psyche to be a special form or function of object-oriented activity. The level of psychical development of a living being is directly proportional to the variety and freedom of its activities.

The aim of this article is to explore the key growth points in activity psychology through the analysis of arguments among its creators - S.L.Rubinstein, L.S.Vygotsky, A.N. Leontiev, and P.Ja. Galperin. Vygotsky dreamed of building a scientific psychology on the model of Marx's Das Kapital; his project is resumed in this article.

The author traces how, due to Walter Cannon's experimental research, Vygotsky came to the activity concept of affect, in which he finds the primary "cell" of the psyche. The problem of the relationship between concept and affect became the central problem of his "acmeistic psychology." While Vygotsky focused on the affective reflection of activity in the subject, Leontiev focused on its cognitive side, directed toward the object. In the objective world, the psyche serves a person's material life-activity, performing a search-and-orientation function. Leontiev considered consciousness a structural projection of that activity, but Galperin argued that Leontiev never managed to overcome the dualism of consciousness and activity.

A new path to the realization of Vygotsky's dream is outlined. The proposed solution is based on Spinoza's concept of affect and the idea of freedom, interpreted as "the affect in the concept." (Vygotsky).
