Figure 3.

Threshold TMRs in the frequency-corrected best 1∕3-octave channel (panel A) and SRM (panel B) as a function of the modulation type, averaged across the masker locations (error bars give the within-subject standard deviation). The horizontal lines in panel B indicate SRMs that were not significantly different at the 0.01 level in a t-test after correcting for multiple comparisons (lines below large symbols for Experiment 1; lines above small symbols for Experiment 2). Different symbols are used to identify the modulation type, as in Fig. 1. The legend in panel B applies to both panels and all modulation conditions.
