Hays, David G."Ethnographers use the early terms in the Berlin-Kay list in almost every societal description that deals with color; they tend to use later terms in fewer descriptions, and only in desciptions that also use some of the early terms" (1118)
Stewart, Robert A. C.Findings: A factor analysis of key dimensions to describe a given culture yielded 12 factors. Factor 4, "paternal authority", loaded highly and positively on household authority with father; high early aggression satisfaction potential; and patrilocal marital residence. Factor 4 loaded highly and negatively on desert grasses; matrilocal marital residence; Athabaskan linguistic affiliation; high anal socialization anxiety; modesty training six years or higher; and matrilineal kin group (58)
