Hyper-volume of eye-contact perception and social anxiety traits

► Spatial response bias of eye-contact was measured along with pupil responses. ► The subjective perception of eye-contact was much larger than the actual eye-contact. ► The pupil was more dilated during the subjective judgment of eye-contact. ► Social anxiety traits were correlated with behavioral performance. ► The lower social anxiety may reflect a restriction of the spatial response bias for eye-contact.
