Figure 1.

Psychophysical measures for all available stimulation sites in the left (open symbols) and right (filled symbols) ears. The first column shows means and ranges of modulation detection thresholds (MDTs) in quiet. The second column shows means and ranges of masked MDTs. The third column shows the amount of masking (masked MDTs minus MDTs in quiet). Correlation coefficients (r) for the across-site correlations between two ears on the psychophysical measure are shown in the upper right corner of each panel. Asterisks indicate statistically significant correlations between the two ears in the across-site patterns (p < 0.05). The ASMs of the left and right ears for the three measures are shown in the upper left corner of each panel. For each subject, the psychophysical measure chosen for site selection is indicated by text “MSS” shown at the lower right corner of the corresponding panel.
