False perspectives.
Textbook accounts of perception frequently contain grossly wrong perspective drawings and/or statements about perspective which misrepresent the available monocular information about distance and size, as well as giving the unfortunate impression that perspective alone elicits only a weak impression of recession. An early example of such a false perspective is the 'Ames window', which is not a correct rendering of a slanted window.
