The analysis for factor 442 at lateral anterior-frontocentral sites revealed no significant effects involving group, although inverted old/new effects tended to be larger in controls (old vs. new, −0.56 ± 0.61 vs. −0.36 ± 0.56) than patients (−0.43 ± 0.66 vs. −0.29 ± 0.57). Thus, there was no evidence that task-related, inverted old/new effects differed between groups (cf. Figure 6G, column 4). At lateral inferior occipitoparietal sites, patients had an overall reduced P3 source compared to controls (0.17 ± 1.47 vs. 0.86 ± 1.69), and this reduction was greater for words (−0.17 ± 1.29 vs. 0.72 ± 1.43) than faces (0.52 ± 1.56 vs. 1.01 ± 1.90), yielding a significant task × group interaction. But again, there were no significant interactions involving group and condition, suggesting similar early inverted old/new effects in patients and controls (Figure 6CE, column 4).
