Washington, October 21: An American study has revealed that the first two points that people look at to tell whether a face is familiar to them or not are around the nose.
Cognitive Scientists Janet Hui-wen Hsiao and Garrison Cottrell from the Temporal Dynamics of Learning Center at the University of California, San Diego, examined this by showing volunteers frontal-view images of faces, one at a time, and recording their eye movements.
They used an eye tracker to record the movements of the participants, which helped detect where on the faces shown the volunteers looked.
