Selective responding by recently separated juvenile rhesus monkeys to the calls of their mothers.
Four juvenile rhesus monkeys responded to the coo-type vocalization of their respective mothers by increasing dramatically their own vocalization rate and their locomotor activities. The juveniles appeared quite disturbed when they heard their mothers voices and this disturbance was, with one exception, apparently specific to their own mothers.
