Other instances of interfamily regulation of contact appear in the ethnographic descriptions presented earlier in this article. For example, Mehinacu families lived in communal dwellings but avoided entering others’ areas; they also erected partitions during periods of seclusion (Gregor, 1970; Roberts & Gregor, 1971). The Ngadju Dayaks of Borneo (Miles, 1970) resided in multifamily units but maintained separate sleeping areas and possessions, ate at different times, and had strong norms against intrusion.
