A researcher in 1988 said that wife abuse stems from "normal psychological and behavioral patterns of most men ... feminists seek to understand why men, in general, use physical force against their partners and what functions this serves for a society in a given historical context". Dobash and Dobash (1979) said that "Men who assault their wives are actually living up to cultural prescriptions that are cherished in Western society--aggressiveness, male dominance and female subordination--and they are using physical force as a means to enforce that dominance," while Walker claims that men exhibit a "socialized androcentric need for power".
