The analysis of family systems has four essential aspects: organizational, terminological, expectational, and behavioral. The family systems of Yugoslavia show, over their history and territory, a range of variation in all these equivalent almost to all we know of the range of Indo-European systems. Yet the variations are no evidence for linear development nor are they the simple reflex of macro-level environmental change. They are best understood as surface adaptations, selective responses out of a consistent body of cultural knowledge. Behavioral accommodations to social and economic change seem readiest to change, then organizational shifts. Expectations of behavior change more slowly. The cognitive structure inferable from native terminology changes most slowly, and within it the affinal terminology, then group terminology, and, finally, consanguineal terminology reflect alterations in social environment.(Description from source).
