This theoretical perspective suggests that Archer’s theme – that competitive aggression is predominantly a male phenomenon, whereas provoked aggression is equally common in males and females – may be explained by sex differences in functioning of these brain systems. For example, a male who assaults another male with the intention of improving his own mating prospects is displaying appetitively motivated predatory aggression (in this case, by the prospect of sexual intercourse) that is hypothetically mediated by the BAS.
