USSR (1917-1964). Following the revolutions of 1917, the USSR was, for a short time, a strong influence on the thinking and imagination of many contemporary Western intellectuals. However, following the death of Lenin, and with Stalin leading the country, psychologists working in the USSR became increasingly insulated from US and European intellectual influences. This led to the development of a unique approach to psychology, best represented by Vygotsky and Luria, that was broadly Marxist in intent, and stressed the interaction between people and culture. In recent years, these psychologists have enjoyed increasingly popularity beyond the USSR.
