Figure Legend:
The settings for the refractive indices lie between the predictions for similarity matches of background distortions (D match) and similarity matches of specular reflections (SR match). (a) Relative position of the refractive indices of the test object (RT) in the interval between the respective predictions of D matches and SR matches for all four thickness ratios (TT/TS) as a function of the refractive index of the standard object (RS). The black line represents the average setting across all four thickness ratios. (b) Example of a fixed standard object (left column, RS = 1.5) and a test object (right column, TT/TS = 100/150) with different settings for the refractive index RT. The topmost object shows a similarity match based solely on background distortions (D match, gained by simulations using the R-T compensation); the lowermost object shows a similarity match of specular reflections (SR match, gained empirically). The refractive index of the center object corresponds to the subjects' mean setting. The images show only a part of the complete stimulus illustrated in Figure 9.
