ACTIVITY THEORY

'Activity theory' is a psychological meta-theory, paradigm, or framework, with its roots in the Soviet psychologist Vygotsky's cultural-historical psychology. Its founders were Alexei N. Leont'ev (1903-1979), and Sergei Rubinshtein (1889-1960) who sought to understand human activities as complex, socially situated phenomena and go beyond paradigms of psychoanalysis and behaviorism. It became one of the major psychological approaches in the former USSR, being widely used in both theoretical and applied psychology, in areas such as education, training, ergonomics, and work psychology [1].

The history of activity theory


The origins of activity theory can be traced to several sources, which have subsequently given rise to various complementary and intertwined strands of development. This account will focus on two of the most important of these strands. The first is associated with the Moscow Institute of Psychology and in particular the ''troika'' of young researchers, Lev Semyonovich Vygotsky (1896–1934), Alexander Romanovich Luria (1902–77) and Alexei Nikolaevich Leont'ev (1903–79). Vygotsky founded cultural-historical psychology, an important strand in the activity approach; Leont’ev, one of the principal founders of activity theory, both continued, and reacted against, Vygotsky's work. Leont'ev's formulation of general activity theory is currently the most influential in post-Soviet developments in AT, which have largely been in social-scientific and organizational, rather than psychological research.
The second major line of development within activity theory involves scientists, such as P. K. Anokhin (1898-1974) and N. A. Bernshtein (1896-1966), more directly concerned with the neurophysiological basis of activity; its foundation is associated with the Soviet philosopher of psychology S. L. Rubinshtein (1889-1960). This work was subsequently developed by researchers such as Pushkin, Zinchenko & Gordeeva, Ponomarenko, Zarakovsky and others, as is currently most well-known through the work on systemic-structural activity theory being carried out by G. Z. Bedny and his associates.
Leont'ev

After Vygotsky's early death, Leont'ev became the leader of the research group nowadays known as the Kharkov school of psychology and extended Vygotsky's research framework in significantly new ways. Leont'ev first examined the psychology of animals, looking at the different degrees to which animals can be said to have mental processes. He concluded that Pavlov's reflexionism was not a sufficient explanation of animal behaviour and that animals have an active relation to reality, which he called ''activity''. In particular, the behaviour of higher primates such as chimpanzees could only be explained by the ape's formation of multi-phase plans using tools.
Leont'ev then progressed to humans and pointed out that people engage in "actions" that do not in themselves satisfy a need, but contribute towards the eventual satisfaction of a need. Often, these actions only make sense in a social context of a shared work activity. This lead him to a distinction between ''activities'', which satisfy a need, and the ''actions'' that constitute the activities.
Leont'ev also argued that the activity in which a person is involved is reflected in their mental activity, that is (as he puts it) material reality is "presented" to consciousness, but only in its vital meaning or significance.

Influence of the theory in the West


The major school of thought that develops the ideas of Leont'ev's activity theory in the West is the tradition of Scandinavian activity theory. Work in the systems-structural theory of activity is also being carried on by researchers in the US and UK.
