Alternative measures of variability quenching explain individual perceptual performance in a similar manner demonstrating the robustness of this relationship. Correlation coefficients between individual magnitudes of variability quenching and perceptual performance estimates (slope and threshold) when using absolute difference between neural variability in the pre (−200 to 0 ms) and post (150–400 ms) stimulus intervals (A) and the ratio between neural variability in the prestimulus (−200 to 0 ms) and poststimulus (150–400 ms) intervals (B). Asterisks indicate significant correlations assessed by a randomization test (p < 0.05).
