A repeated measures ANOVA was used for the analysis of the amplitude and latency of the P1 and N1 components. Visual Field (LVF vs. RVF), Hemisphere (electrodes contra- vs. ipsilateral to the stimuli), and Electrode (4 pairs, see above in EEG Analysis) were entered in the analysis as within-subjects factors, and Diagnosis (SZ vs. HC) was entered as a between-subjects factor.
