PERCEIVED DEPTH FROM SIMULTANEOUS CHANGES IN LENGTH AND DIRECTION OF A SINGLE LINE

Using a configuration of three lines joined like hands on a clockface, Brigner, Deni, and Hildreth in 1994 reported empirical support for Wa llach, Adams, and Weisz's 1956 hypothesis regarding the elicitation of perceived depth by simulataneous changes in length and orientation of a configuration's elements. The current investigation extended these findings by showing that perceived depth can be elicited by simultaneo us changes in size and orientation of either two lines or a single lin e.
