Use of Experimenter-Given Cues in Visual Co-Orienting and in an Object-Choice Task by a New World Monkey Species, Cotton Top Tamarins (Saguinus oedipus)

.
ABSTRACT
 
Two different methods assessed the use of experimenter-given directional cues by a new world monkey species, cotton top tamarins. Experiment One used experimenter-given cues to elicit visual co-orienting toward distal objects. Experiment Two used experimenter-given cues to generate accurate choices in an object choice task. While there were strong positive correlations between monkey pairs to co-orient, visual co-orienting with a human experimenter occurred at a very low frequency to distal objects. Human hand pointing cues generated more visual co-orienting than did eye gaze with or without head and body orientation. Significant accurate choices of baited cups occurred with human point/tap cues, and human look cues, where looks involved head and body orientation as well as eye gaze. The results highlighted the importance of head/body orientation to induce shared attention in cotton top tamarins, both in a task that involved food-getting and a task that did not.
