The article covers the analysis of the child's psychology compliance with culture rules--the cultural congruence. The description of the technique aimed to detect the cultural congruence of five- to six-year-old children is presented. The technique is made on the basis of the revealed range of rules of a child's and adult's interaction in a social situation. It provides the possibility to determine the child's compliance with the norms according to four scales, in combination they form the cultural congruence indicator. Scales of cultural congruence are correlated to a number of factors: "compliance with adult's expectations," "obedience," "self-control," "observance of safety rules," "self-care." The technique of cultural congruence determination is approved for the Russian sample of children living in the megalopolis with the population over one million people. Along with the empirical material, special attention is paid to the theoretical analysis of differences in the positions 'personality' and 'subject' in their interaction with culture as the system of standard situations.
