Vision, Visual perception
Common experience suggests that most people can tell whether they are being looked at by another person who is about 8 m away. However, the results of past experiments, which used distances of no more than about 3 m, have implied that this cannot be done if the person looked at (Receiver) judges only by the iris-sclera configuration of the person looking (Sender). This is true even if eye contact is defined simply as identifying on-face gazes (FGs). It has been suggested that in everyday experience eye contact is accompanied by cues other than iris position, and that these non-iris-position (NIP) cues to Receiver account for recognition at longer distances. The hypotheses of the present experiment are that FGs can be identified at considerably more than 3 m, without NIP cues: and that this happens because as features of Sender's lower face fall within Receiver's central vision at longer distances, Receiver is able to use them for triangulating the position of Sender's irises.
