Figure 4. Experiment 1: Comparison of selection-based and adjustment-based constancy across instructional groups.

Figure 4

Panel A shows mean constancy indices for each group for color selection (filled bars) and asymmetric matching (open bars). Panel B shows the standard deviations of the constancy indices for each group. In both panels, error bars are bootstrapped 90% confidence intervals. Panel C plots mean (over targets) selection-based indices against corresponding mean adjustment-based indices for subjects in the neutral (red) and physical spectrum (green) instructions groups. Panel D shows the corresponding plot for objective reflectance (black) and apparent reflectance (gray) groups. Error bars represent +/− 1 SEM. Symbols for individual subjects are the same as in Figure 3. In panels C and D there are two points for each subject as the means for each illuminant-changed condition are plotted separately.
