Tilting the head downwards creates an artificial appearance of a facial action that has a strong effect on social perception. Study reveals social judgements about the face are not driven by the face shape or muscularity alone, but by the movement of the head.
A new eye tracking study reveals left gaze bias is replaced by an upper eye bias when we look at faces tilted to an eleven degree angle. Researchers say the findings could help social engagement in those with ASD as the head tilt helps people focus more on the eyes, making others seem less threatening and more approachable.
