ERPs recorded to faces with direct and averted gaze in 4-month-old infants. (a) All but one of the electrodes over the occipital cortex recorded an enhanced N170 response (peaking at 240 ms after stimulus) to the faces with direct gaze compared with the faces with averted gaze. (b) ERPs to the two kinds of stimuli averaged across all occipital electrode sites. (c) Spherical spline interpolations (22) for the surface distributions of the average amplitude at 240-ms latency show an enhanced medial occipital response to mutual gaze compared with averted gaze. White spots mark the electrode locations used in the statistical analyses.
