An exploratory study of gaze-monitoring in nonhuman primates

Abstract

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. © 1996 Japanese Psychological Association.
