Effects of axes of symmetry of frames on visual search tasks
Webpage designers, photographers, painters and other visual artists are faced with questions of how to position objects within a frame so that their composition is aesthetically pleasing and objects of interest are easier to detect. Aesthetic judgments of spatial layout have been described by positive feelings (e.g.,“Wow! I love it”) and negative feelings (e.g., “Ugh! I hate it”) and it has been reported that certain spatial layouts are preferred more than others within a rectangular frame (Palmer, Gardener & Wickens, 2008).

Experimental results by Palmer and Guidi (2008) using a “goodness of fit” rating task show that the structural skeleton of a rectangular frame are the preferred location with the center being the most potent location (the point of intersection of its vertical and horizontal axis of symmetry).

The goal of this project is to study the accuracy and speed of visual search tasks for Gabors chains that are placed in different locations within a frame. For example, how do performance in search tasks compate when the Gabor chain is placed along the axes of symmetry in a square/rectangular frames (see Figure-2A ) compared to other postions (see Figure-2B ).
