Abstract

We investigated whether orientations shape-from-shading of oval pattern influence visual search processes differently. In Experiment 1, the strength of orientation was manipulated by using three ratios of vertical to horizontal axes and vice versa: 1:4, 2:4, 3:4. Each type of oval was used for target or distracter. In Experiment 2, shape-from-shading was applied to oval pattern, so the patterns were convex or concave. In Experiment 1, vertically elongated oval target conditions were faster than horizontally elongated target conditions. And search asymmetry was getting obvious as ratio between horizontal and vertical axis became low. In Experiment 2, there was an interaction between orientation and shading. A vertical target was popped-out quickly against horizontal oval background. only when background was convex. In contrary, search for horizontal target against vertical background was faster in case of concave background than in convex. The results strongly suggest that horizontal or vertical orientation are not equally sensitive in visual system. Visual system seems to find an vertical object at horizontal background easier than an opposite case under naturally lit environment.
