Top, Mean f1–f2 frequency discrimination accuracy (% correct) for each f1 frequency, and linear regression slopes for the different modality conditions. Asterisks indicate significance of a linear trend across f1 frequencies (p < 0.05, Bonferroni corrected). Bottom, Same as top, for RT (milliseconds).
