The study by Chris Kelland Frees and Alan Kingstone investigates the reflexive orienting of attention triggered by nonpredictive gaze shifts in adults. Participants were presented with a simple line drawing of a face looking left, right, or straight ahead, followed by a target letter (F or T) appearing to the left or right of the face. Despite being informed that the gaze direction did not predict the target's location, response times were faster when the target appeared at the location where the eyes were looking. This facilitation effect was rapid, short-lived, and did not result in any delay at the uncued location. The findings suggest that the brain is capable of shifting attention reflexively in response to uninformative gaze cues, even when the subject is aware that the gaze direction is not predictive of the target's location. The study implications for theories of social attention and visual orienting are discussed, and the brain mechanisms underlying this phenomenon are considered.The study by Chris Kelland Frees and Alan Kingstone investigates the reflexive orienting of attention triggered by nonpredictive gaze shifts in adults.
