Laboratory of Experimental Psychology, University of Belgrade The aim of the study was the investigation of form, spatial set organization and visual attention in visual search of illusory contours. Three visual search experiments were conducted. In the first experiment, where the simple detection procedure was used, subject's task was to detect square among vertical and horizontal lines. Other experiments investigated visual search of illusory contours in four different set organizations. Introduction of set organization was the way of manipulation of target's eccentricity among other elements. Analysis showed different type of search of the regular and the illusory square figure. The search profile of the regular square proved to be parallel, while all the searches of the illusory squares remained serial. Set organization had important role in visual search of illusory contours. Regardless of serial profile, visual search was faster in cases where target figure was more salient due to the background elements organization
