โฆ Synopsis
Face-like patterns attract attention from both human and nonhuman primates. The present study explored the facial preferences in infant pigtailed macaques (Macaca nemestrina).

The facial features in the drawings were arranged in positions ranging from a normal to a scrambled face. The subjects looked at the normal face more than expected by chance (P < .02), suggesting a preference, whereas the distorted faces were observed randomly. The normal face may have been preferred because the eyes were in a normal position within the facial outline. Am.

Human infants' responsiveness to the audible and visible features of human faces was studied by habituating them to a person speaking a prepared script in an adult-directed manner and then administering a series of separate test trials where a person could be seen, heard, or seen and heard singing.
