AI Article Synopsis
- The study looked at how babies understand where someone is looking when their heads are tilted but their eyes are the same.
- Researchers found that 4- to 5-month-olds and 7- to 8-month-olds can tell if the gaze is direct or looking away based on the angle of the head.
- This means that by 4 to 5 months old, babies are already good at figuring out where someone is looking, even if their head moves.
Article Abstract
The current study examined infants' sensitivity to Wollaston's effect: When identical eyes are placed in differently angled faces, the perceived gaze direction shifts toward the orientation of the face such that physically, the direct gaze is perceived as averted toward the orientation of the face. Consistent with Wollaston's effect, we found that looking toward direct and averted gaze by 4- to 5- and 7- to 8-month-olds (n = 40) was affected by the head orientation context. These results demonstrate that infants aged 4 to 5 and 7 to 8 months integrate eye and head information to perceive another's gaze direction. In light of recent psychophysical findings, the current results suggest that the visual function supporting constant gaze perception across head rotation is already at work by 4 to 5 months of age.
