Table 1. Behavioral results.

Contrast of the subjectively equivalent “Real” stimulus reported for all observers (standard errors of the means are reported in parentheses). BC: contrast of the central border in “Illusory” and “Control” stimuli. Results from the dynamic version of the experiment are shown for the two observers who participated in that experiment (KD and HB).
