Abstract
This chapter comments on Anne Treisman's 2003 paper Representation of statistical properties, published in Vision Research and written in collaboration with Sang Chul Chong. Treisman and Chong report the results of their experiments on perceptual representation of statistical properties by determining the psychological mean of two sizes and measuring thresholds for judging the mean with arrays of twelve circles of heterogeneous sizes. They investigated statistical processing in the domain of size by testing perception or memory for the mean size of sets of circles. This chapter discusses the findings of Treisman and Chong by focusing on summary representation, also known as ensemble coding or ensemble perception, in which the visual system naturally represents sets of similar items using summary statistics. It also considers the history of summary statistical perception and the ongoing debates surrounding it, along with some of the more influential work and directions for future research.
