 Abstract: Despite considerable evidence that neural activity in monkeys reflects various aspects of face perception, relatively little is known about monkeys face processing behaviour. The present study used an adaptation paradigm to test whether untrained Rhesus macaques display two hallmarks of face processing observed in humans, namely, a subordinate entry point, here, the default recognition of faces at the individual level of categorization, and holistic effects, i.e., perception of facial parts as an integrated whole. In Experiment 1, monkeys showed greater rebound from adaptation to conspecific faces than to animals and non-conspecific faces at the subordinate level. In Experiment 2, exchanging only the bottom half of a monkey face produced greater rebound in aligned than in misaligned composites, indicating that for normal, aligned faces, the new bottom half has influenced perception of the whole face. These experiments show that macaques naturally display the distinguishing characteristics of face processing seen in humans.
