Abstract:
To define the role of statistical features of images in visual working memory, we compared the ability of subjects (N=6) to identify changes in arrays of black and white checks when these changes altered some aspect of their statistical structure, versus when these changes did not. Alteration of luminance statistics or local higher-order statistics improved performance, but alteration of the degree of bilateral symmetry did not. The dependence of performance on the degree of statistical change indicated that statistical information was represented in a graded, rather than categorical, fashion.
