A, Left column, Mean areas of illusory, imagined, and combined squares. Right column, Mean velocities at which illusory, imagined, and combined squares were drawn by hand. B, Top, Corresponding statistical comparisons (Friedman's test on square areas and ANOVA for paired data on square velocities) and associated p values (p). Bottom, p values associated with the pairwise comparisons (Wilcoxon's test on square areas and Newman–Keuls test on square velocities) between imagined (IM), illusory (ILL), and combined squares.
