The Flashed Face Distortion Effect is an optical illusion that is one of the weirdest, freakiest brain phenomenon you’ve ever experienced. Jason Tangen, Sean Murphy and Matthew Thompson, the authors of this scientific study, explain.
When cycling through the faces on a computer screen, each face seems to become a caricature of itself and some faces appear highly deformed, even grotesque. The degree of distortion is greatest for faces that deviate from the others in the set on a particular dimension.
This new method of image presentation, based on alignment and speed, could provide a useful tool for investigating contrastive distortion effects and face adaptation.
