Table 3.

The differences in mean hue ratings in the yellow-blue and green-red directions (after arcsine transformation for uniform variance) in the color-only and simultaneous conditions (color-only minus simultaneous). Color ratings in the simultaneous condition include all seen stimuli (i.e., ratings of 2 or more). p-values reflect significance according to the two-tailed z-test. The difference in the yellow-blue direction is significant at high intensity for Subject 4.
