Attention alters appearance. (a) Appearance psychometric function. Percentage of responses in which observers reported the contrast of the test patch as higher than the standard, plotted as a function of the physical contrast of the test patch. Data are shown for the neutral and peripheral conditions (test cued and standard cued). (b) Effect of covert attention on apparent contrast illustrating the point of subjective equality for the different cueing conditions (Adapted from Carrasco et al., 2004, Figs. 4 and 5).
