Abstract

What are the neuronal correlates of reflexive shifts of attention triggered by eye gaze direction? Event related potentials (ERPs) were measured on 14 subjects performing a spatial attention task where eye gaze direction of a face cued the location of a forthcoming target. Subjects were faster in detecting a validly cued target, i.e. one appearing at the location the eye was gazing at, compared to invalidly cued targets, despite the non-predictive value of the eye cues. ERP results showed an enhanced and earlier occipito-parietal PI and NI for valid trials, demonstrating the early modulation of visual input by attentional allocation. These findings provide the firstevidence that social attention can rapidly modify the processing of visualinformation in extrastriate cortex.
