eaction times would be faster that controls when targets matched the pre-constancy
grouping solution of the prime at short prime durations. Similarly, it was expected that
reaction times would be faster that controls when targets matched the post-constancy
grouping solution of the prime at long prime durations.

Note. (a) Pre-constancy match experimental target. (b) Example post-constancy experimental match target.
The results revealed that reaction times to pre-constancy match targets were
significantly faster than those to post-constancy match targets at prime durations shorter
than 450ms (see Figure 15A). This finding was consistent with Schulz and Sanocki's
(2003) direct report research. However, reaction times to post-constancy match targets
were not significantly different from zero at prime durations beyond 450ms (see Figure
15B). This finding was inconsistent with previous direct report research and has been
taken to suggest the possibility that there exists an ambiguity between pre- and post-
constancy color representations beyond 450ms.
