Food aversion learning in Japanese monkeys (Macaca fuscata).

Tetsuro Matsuzawa, Yoshinori Hasegawa

Abstract

Japanese monkeys consumed two kinds of food, the novel almonds and the familiar sweet potatoes, simultaneously, and then received a cyclophosphamide injection (20 mg/kg) intravenously. As the food-poison pairing was repeated, they first avoided the novel food completely, and then came to suppress eating the familiar one. During the subsequent extinction tests, the aversion to the familiar food was extinguished rapidly, whereas the aversion to the novel one was retained more than 2 months. In food aversion learning in a mixed situation, monkeys have a strategy to avoid a noxious food on the basis of the novelty of the food.
