Factors influencing the expression of aggression during introductions to rhesus monkey groups (1974)

Bernstein, I. S., Gordon, T. P., Rose, R. M.

Abstract

What we have demonstrated is that the introduction of rhesus monkeys [both sexes, different ages, different rearing histories/personalities] to an established rhesus monkey social unit can be a potent stimulus for eliciting aggression. ... Rhesus monkeys in the laboratory have well-earned reputations for their aggressive response and near-intractable disposition.
