The Greebles refers to an invented category of novel objects used as stimuli in psychological studies of object and face recognition. They were named by the psychologist Robert Abelson.[2] The greebles were created for Isabel Gauthier's dissertation work at Yale,[3] so as to share constraints with faces: they have a small number of parts in a common configuration. Greebles have appeared in psychology textbooks,[4][5] and in more than 25 scientific articles on perception (see below). They are often used in mental rotation task experiments.[citation needed]
