The effects of viewing time on Necker cube reversals. essay
We used the Necker cube as a stimulus cm line length of the perimeter cube. At a viewing distance cm, the resulting viewing angle. 8. The stimulus was presented as white lines on a black background. The top right corner of the cube served as an attachment point when viewed from the upright position of the cube, see Figure 1. 2.3.The Necker cube is not only Bi-stable. Graham Hamilton. Department of Psychology and Sport, Faculty of Health and Life Sciences, Y ork St John. University, Lord Mayor's W alk, Y ork, EX. Recently, we estimated the amount of reaction time variance related to orientation reversals of a Necker cube Kornmeier and Bach, 2004b in the following way: using depth cues, we created two unambiguous and thus perceptually stable variants of the Necker cube, Figure Figure1B . Regarding spatial context manipulations, Wallace 1988 showed that once the Necker cube is presented in a context consisting of geometric figures, that is, squares, triangles, crosses, or parallelograms, the reported rate of reversals is slower than that obtained in response to a single cube viewing condition..
