Dissimilar efficiency of the temporal integration of segregated A (approx. 4 Hz) and B (approx. 2 Hz) streams. The conditions from part 1 (0- vs. 10-semitones) and part 2 (2- vs 4-semitones) are presented on the right and on the left plot, respectively. Error bars indicate the 95 % confidence intervals for the within-subject effect (Condition x Target Frequency).
