title: Evolutionary developmental explanations of gender differences in interpersonal conflict: A response to Trnka (2013).
abstract: In focusing on gender differences in anger expression, Trnka (2013) provides a useful complement to the article by Ingram et al., (2012) analyzing gender differences in children's narratives about peer conflict. I agree that gender differences in anger are more likely to be the result of differential socialization processes regarding the expression of anger than by innate differences in the experience of anger. Gender differences in intersexual anger and aggression are likely to be affected by the social context, and especially whether a female is interacting with a romantic partner or an unknown male. The implication of socialization in anger expression raises the possibility that culture plays a causal role in encouraging cooperative breeding by inhibiting inter-female aggressive displays. Another of Trnka's proposals, that the expression of anger contributes to reconciliation and inhibits long-term relationship damage, is intuitively plausible and supported by the research literature, but not by data from the current study.
