The analysis for factor 723 at medial centroparietal, parietal, and occipitoparietal sites revealed a highly significant group main effect that originated from an overall larger source in controls compared to patients (0.22 ± 1.08 vs. −0.09 ± 1.17; cf. Figure 6DF, columns 1 and 2). More importantly, there was also a highly significant group × condition interaction, stemming from a greater old/new effect for controls (old vs. new, 0.51 ± 1.11 vs. −0.07 ± 0.96) than patients (0.06 ± 1.28 vs. −0.24 ± 1.03), and a significant group × condition × task interaction. Simple group × condition interactions for each task revealed that a greater old/new effect for controls than patients was significant only for words, F(1, 97) = 12.1, p = 0.0008 (old vs. new, for controls: 0.51 ± 1.02 vs. −0.26 ± 0.91; for patients: 0.02 ± 1.20 vs. −0.35 ± 0.92), but not for faces, F(1, 97) = 3.19, p = 0.08 (old vs. new, for controls: 0.51 ± 1.19 vs. 0.11 ± 0.98; for patients: 0.10 ± 1.35 vs. −0.12 ± 1.11). This three-way interaction qualified
