Lateral organization and aesthetic preference: the importance of peripheral visual asymmetries.

The observation that right-handers prefer pictures with the important content to the right was examined. In the first experiment, subjects manipulated the two elements of the composition. They showed a bias to place the principal object to the right and, with a central principal object, the secondary object was placed to the left. In a further experiment, eye movements were recorded while subjects scanned the pictures used in the first experiment and a rightward lateral bias in gaze direction was observed. It is argued that lateral asymmetry in preferred picture arrangements is not the result of a counterbalancing of content against perceptual bias, but a consequence of gaze being directed to informative content on the right, leaving more of the secondary content within the left visual field and associated with attentional bias or processes of the right hemisphere.
