Here, we offer several manipulations to highlight that the fat-face illusion is not restricted to the bottom image, isn’t a property of internal features, facial contour/texture, and in general isn’t even specific to faces. We propose the axis of horizontal asymmetry account to contextualize fat-face illusion as a geometry-led illusion.enface perception | frames of reference | shape | shapes/objectsjournal article10.1177/2041669520981094334890742-s2.0-85098009399https://api.elsevier.com/content/abstract/scopus_id/85098009399
