The philosophical foundations of Aleksandr R. Luria's neuropsychology.

This article attempts to show that the cultural-historical psychological theory of Aleksandr R. Luria (Luriya) and his colleagues is based on the foundations of historical materialism. It argues in particular that Luria's psychology, neuropsychology, and brain theory are integrated in the same scientific research program and are based on the same philosophical premises, and that his theories must be interpreted in the Marxist context in which they are embedded. Luria's research program asserts that the development of higher mental functions depends on the appropriation of cultural means, particularly language, within social practice. Moreover, the brain structures underlying mental functions are also dependent on the appropriation of cultural means. Luria's clinical diagnosis and his program for rehabilitation of patients with brain lesions are based on his psychological theory and brain theory. The following analysis of Luria's comprehensive program will show that a socio-cultural non-reductive explanation of mental functions and their underlying brain structures may have implications for the philosophical discussion of the mind-brain problem.
