| Research Abstract |
We investigated how Japanese macaque mothers and infants behave in mother-infant conflict over parental investment. Mothers allocated their infant protection efforts according to the nature of conspecific individuals proximate to the infants. We compared maternal styles exhibited when mother and infant were in contact and those exhibited when they were not, and showed that maternal protectiveness was consistent between these two situations. However, we observed that mothers who frequently hold their infants in contact situation respond less frequently to the infants' distress calls when they are not in contact. This suggests that some mothers show great interest in their infants only when they are in contact.
