Eleven species of nonhuman primate were tested in a gaze‐monitoring task to examine whether they would look where the experimenter looked or pointed. Chimpanzees and an orangutan showed higher correct‐response rates than other species. A high correlation was found between correct responses on the gaze‐monitoring task and the length of time that the subject continuously concentrated on the experiment.
