Eye gaze cueing facilitates neural processing of objects in 4-month-old infants.

A major issue in developmental science is how infants use the direction of other's eye gaze to facilitate the processing of information. Four-month-old infants passively viewed images of an adult face gazing toward or away from objects. When presented with the objects a second time, infants showed differences in a slow wave event-related potential, indicating that uncued objects were perceived as less familiar than objects previously cued by the direction of gaze of another person. This result shows that the direction of eye gaze of another cannot only bias infant attention, but also lead to enhanced information processing of the objects concerned.
