Psychological Differentiation in Cross-Cultural Perspective

Cross-cultural studies of psychological differentiation are reviewed with the objectives of: examining the applicability, across cultures, of the main propositions of differentiation theory and the generality of its intracultural supporting data; identifying extensions of the theory, and of its empirical base, suggested by the cross-cultural findings; and delineating problems in the existing data and useful lines of further cross-cultural inquiry. The evidence on self-consistency, age changes and stability indicates that these aspects of differentiation show patterns in other cultures essentially similar to those observed in the original American studies. Numerous cross-cultural studies have sought the sources of individual and group differences in differentiation in family practices, in cultural influences and in ecological pressures. The evidence from these studies suggests that less differentiated functioning, including a more field-dependent perceptual mode, is associated with insistence upon adherence to adult authority, female salience and the absence of strong male role models in the family; “tight” organization and stress upon conformity in society; and sedentary agricultural and pastoral ecological settings. In contrast, more differentiated functioning, including relative field independence, are associated with encouragement of autonomy in the family, “loose” social structure and mobile hunting ecological settings. The small sex differences in field-dependence-independence, beginning in adolescence, repeatedly observed in Western studies are not universally evident in the non-Western data. Sex differences appear to be common in samples at the sedentary agricultural end of the ecological spectrum and less evident in mobile hunting samples. Sex differences also seem to be more prevalent in “tight” than in “loose” social settings.
