Abstract

A new everyday visual size illusion is presented-the Pot/Lid illusion. Observers choose an unduly large lid for a pot. We ask whether the optic slant of the pot brim would increase its apparent size or if vision underestimates the size of tilted lids.

Keywords: horizontal–vertical; illusion; optic slant; size; vision.
