LEARNING TO USE EXPERIMENTER-GIVEN CUES DURING AN OBJECT-CHOICE TASK BY A CAPUCHIN MONKEY

A juvenile male capuchin monkey, Cebus apella, was trained to use beha vioral cues given by the experimenter during an object-choice task. Fi ve conditions were used in different training phases: tapping on the c orrect object, gazing plus pointing at the correct object, gazing clos ely, gazing alone, and glancing without head orientation. The subject learned to use all of the experimenter-given cues except glancing, whi ch may indicate a lack of perspective-taking by the monkey.
