Apparent Movement of a Necker Cube

Abstract

* Received for publication May 8, 1963. The first two experiments were performed at the U.S. Naval Medical Research Laboratory with apparatus generously loaned by the Behavioral Sciences Laboratory, Wright-Patterson Air Force Base. The third experiment and the preparation of this report were supported by Grant NSF G-16486 and PHS Training Grant 2G-1011 Special to the Center for Sognitive Studies, Harvard University. 1Wolfgang Kohler, Dynamics in Psychology, 1940, 67-82; Wolfgang KShler and Hans Wallach, Figural after-effects, Proc.
