Abstract
Brightness enhancement was measured under 4 conditions of judgment (simultaneous or successive comparisons and in the presence or absence of an adapting field) in a 2 X 2 factorial design. Brightness enhancement was greater for successive than for simultaneous comparisons, and was also favored when the adapting field was removed during the comparisons. The greatest amount of enhancement, then, was found when the intermittent light was isolated in space and time from all other stimuli, thus contradicting the suggestion that brightness enhancement might be an interaction artifact. However, these results also demonstrate that brightness enhancement is sensitive to the presence of other stimuli. Introspections of Os suggest that subjective colors were produced to a greater degree during simultaneous than during successive comparisons. (17 ref.)
