Figure 2

Features of the sequences of trials in the three experimental conditions. The background colour wash and test illuminant letter indicates the simulated illumination on the test patch: sunlight (A) or skylight (B). The number with each illuminant letter indicates the number of trials since the test patch illumination changed, which happened every 10th trial. The three conditions are matched in the sequence of illumination on the test patch, but differ in the illumination of the background region. This was (i) the same as the test patch in the global condition, (ii) black in the isolated condition, and (iii) Illuminant C in the inconsistent condition. The stimulus examples in this figure have been cropped so that the test patch is clear.
