Five main effects of local image statistics on fixation durations for scene memorization (dash-dotted lines), preference judgment (solid lines), and scene search (dashed lines). The dependent variable is the duration of the current fixation n. The input variables are (a) luminance, (b) luminance contrast, (c) edge density, (d) clutter, and (e) synergistic segmentation, calculated for 1° circular patches around the current fixation location n. Error bars are within-subjects standard errors, using the method described by Cousineau (2005). Data are from the right eye
