EEG data were processed offline using BrainVision Analyzer software (Brain Products, GmbH, Gilching, Germany). A 0.5 Hz high-pass digital filter with a 24dB/octave roll-off was used to attenuate low frequency artifacts, as well as a 60 Hz notch filter to remove line noise. Activity that exceeded +/− 100 μV was removed and blinks were initially corrected using an algorithm (Gratton et al. 1983). Participants were included in subsequent analyses only if they had at least 50 s of artifact-free EEG data (Lund et al. 1995). There were no significant differences in the average duration of artifact-free EEG data segments across patient groups (SZ: M=149s, SD=35.75, BP: M=146s, SD=39.20, NC: M=151s, SD=34.16; p>.50).
