November 5] 1896 – June 11, 1934) was a Soviet Belarusian psychologist, the founder of a theory of human cultural and biosocial development commonly referred to as cultural-historical psychology, and leader of the Vygotsky Circle. Vygotsky's main work was in developmental psychology, and he proposed a theory of the development of higher cognitive functions in children that saw the emergence of the reasoning as emerging through practical activity in a social environment.
During the earlier period of his career he argued that the development of reasoning was mediated by signs and symbols, and therefore contingent on cultural practices and language as well as on universal cognitive processes.
