These observations were confirmed by the statistical analyses. Significant group main effects (RM, F[2,92] = 3.13, p < .05, η2p = .064; WM, F[2,109] = 3.64, p = .03, η2p = .063) stemmed from smaller N1 sink amplitudes for auditory hallucinators compared to nonhallucinators and healthy controls, who did not differ from each other (between group contrasts: RM, AH vs. NH, F[1,92] = 3.90, p = .05, AH vs. HC, F[1,92] = 6.05, p = .02, NH vs. HC, F[1,92] < 1.0, n.s.; WM, AH vs. NH, F[1,109] = 5.96, p = .02, AH vs. HC, F[1,109] = 6.30, p = .01, NH vs. HC, F[1,109] < 1.0, n.s.). There were also highly significant main effects of task (RM, F[1,92] = 36.4, p < .0001; WM, F[1,109] = 49.3, p < .0001) and hemisphere (RM, F[1,92] = 11.7, p < .001; WM, F[1,109] = 8.75, p = .004), as well as highly significant task × hemisphere interactions (RM, F[1,92] = 54.0, p < .0001; WM, F[1,109] = 59.6, p < .0001), but none of these effects interacted with group (all
