TABLE 2.
Part a) shows results of univariate ANOVAs on individual subjects’ results in all three conditions of experiment 1. This analysis is repeated for the PSA and PSC conditions only in part b). Part c) shows the results of univariate ANOVAs performed on each subject’s results in the SYM condition of experiment 1. The first column shows the main effect of electrode. The second two columns show the (uncorrected) significance levels of t tests between the MLTs for the masker on electrodes (-1,1) and, respectively, (-2,0) and (0,2). Comparisons that were significant with a p value of 0.001 or lower would have survived Bonferonni correction, whereas the two comparisons (both for subject AB2) significant at the p < 0.05 level would not have
