This study investigated whether a human model's facial gestures, speed of head turn and visibility of face influenced gaze-following responses (GFR) in pigtail macaques. A human provided gaze cues by turning her head 90 degrees in one of four directions. Head turns were immediately followed by a facial movement (pucker, eyebrow raise, tongue protrusion, neutral), or were executed swiftly (< 0.5 s), slowly (3 s) or whilst facing away from the monkeys. All monkeys reliably followed the gaze in all conditions with no differences between conditions. A greater frequency of GFR was found in females compared to males, and two hypotheses for this finding are discussed.
