Abstract
The justification for the “generalization that primate males are more aggressive than females” (Fedigan & Baxter, 1984) was tested in a troop of 24 captive rhesus monkeys. Males (N=9) were more dominant than females (N=15), i.e., they had more subordinate partners (\(\bar x\) m=17.0 vs.\(\bar x\) f=6.6;p<0.01); hence, their aggression rate was higher (\(\bar x\) m=77.6 vs.\(\bar x\) m=38.1;p<0.05). However, adjusting the rate of aggression according to the number of subordinate targets revealed no gender difference and males directed numbers of aggressive acts against individual subordinate partners that were not higher than those of females (\(\bar x\) m=4.4 vs.\(\bar x\) f=5.4;p>0.1). It was concluded that aggressiveness is an individual attribute that is (1) independent of dominance status, and (2) independent of sex.
