The present study attemots to find out the relations between the socialization patterns in family and cognitive styles of children with reference to social class in Korea. On the base of the theoretical assumption of Bernstein’s sociolinguistic theory on socialization, the study seeks. answer to the following problems. Firstly, what are the relations between social class status of family and cognitive styles of children? Secondly, what are the relations between social class status of family and its socialization patterns? Finally, what are the relations between socialization pattens in family and cognitive sty les of children? To answer the questions under the study, a conceptual scheme of the relations between the variables is formulated. Three kinds of variables, i.e., social class, socialization patterns, and cognitive styles were secured from responses to a set of guestionnaire and test. For social class variable, social class index of children’s family is measured in terms of educational level and occupational status of their father. Socialization patterns were identified from a questionnaire of socialization patterns composed of 24 items in accordance with the theoretical scheme. And cognitve styles of children were measured by the Hidden Figures Test published by Educational Testing Service. The methods of analysis in the study were the “F” test for the measure of the differences of cognitive styles and socialization patterns between the groups, and multiple regression analysis for the measure of the degree of predictability of the subvariables of social class and socialization patterns toward cognitive styles of children. The hypotheses tested and the results obtained may be summarized as the follows: Hypothesis 1 is that the cognitive style of children from the upper social class is more field independent than that from the lower class. This hypothesis is confirmed at a significance level of . 01. Hypothesis 2 is that the socialization pattern of the upper class family is more personoriented than that of the lower class. This hypothesis is confirmed at a significance level of . 01. Hypothesis 3 is that the cognitive style of children experienced person-oriented socialization pattern is more field-independent than that of children experienced position-oriented one. This hypothesis is confirmed at a significance level of. 0l. Hypothesis 4 is that subvariables of social class and socialization patterns carry different predictability toward cognitive styles of children. This hypothesis is confirmed at a significance level of. 01 or . 05. And the predictability of subvariables reveals an order of education level, modes of social control, role system, communication system of family, and occupation. In summary, the results of the study support that there is a significant relationship between the socialization patterns in family and the cognitive styles of children with reference to social class in Korea. Besides these empirical findings, there remains a serious theoretical problem of cultural relevance. Since Bernstein’s sociolinguistic theory is based on the concrete social reality of England, a close- examination of relevance of the model in Korean socio-cultural setting must be preceded before the further generalization.
