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.
