...psychology has barely begun to study the specific sociohistorical shaping of mental processes. We still do not know whether changes in sociohistorical structures or changes in the nature of social practice result only in broadened experience, acquisition of new habits and knowledge, literacy, and so forth, or whether they result in radical reorganization of mental processes, changes at the structural level of mental activity, and the formation of mew mental systems. Proof of the latter would be of fundamental significance for psychology as a science of social history.
