Gaze deflection reveals how gaze cueing is tuned to extract the mind behind the eyes

Suppose you are surreptitiously looking at someone, and then when they catch you staring at them, you immediately turn away. This is a social phenomenon that almost everyone experiences occasionally. In such experiences—which we will call gaze deflection—the “deflected” gaze is not directed at anything in particular but simply away fromthe other person. As such, this is a rare instance where we may turn to look in a direction without intending to look there specifically. Here we show that gaze cues are markedly less effective at orienting an observer’s attention when they are seen as deflected in this way—even controlling for low-level visual properties.We conclude that gaze cueing is a sophisticated mental phenomenon: It is not merely driven by perceived eye or head motions but is rather well tuned to extract the “mind” behind the eyes.
