Note. Sat. = Saturation, LP = Line Position, E1 = Exterior stimulus on first-processed dimension, I1 = Interior stimulus on first-processed dimension, E2 = Exterior stimulus on second-processed dimension, I2 = Interior stimulus on second-processed dimension, R = redundant stimulus, M = Mean RT difference (ms).

For the contrast-category t-tests, the df vary between 687 and 712, so the critical values of t are essentially z.
