Аннотация:The paper deals with research domains’ placement for Historical Psychology. Being stratified functionally around it as the core, they form two strata (tool-sharing Psychology and fact-supplying others with History among them) joint by Linguistics. Together with the problem field, defined by the author subject (philogenesis of ontogenesis in sociogenesis), object (explications of society members’ psychics on its various stages) and research item (epoch psychological portrait as an integral sociogenesis stage) they place Historical Psychology within Psychology.
