Contrast enhancement effects

	Proportions	Pupil size
Dominant percept	F(1,9) = 4.47 p = 0.06 logBF = 0.19	F(1,9) = 18.40* p = 0.002 logBF = 13.99
Contrast increment	F(4,9) = 4.23* p = 0.007 logBF = −0.44	F(4,9) = 1.16 p = 0.34 logBF = −1.30
Dominant percept × contrast increment	F(4,9) = 39.75* p < 0.001 logBF = 12.36	F(4,9) = 14.11* p < 0.001 logBF = 3.38

Two-way ANOVA for contrast enhancement results, with factors: dominant percept (white/black disk) and contrast increment (0%, 25%, 50%, 100%, 150%). Greenhouse–Geisser corrected values. * for p < 0.05 or lower.
