Few studies have investigated ERP correlates of recognition memory performance in schizophrenia (Kayser et al., 1999; Baving et al., 2000; Matsumoto et al., 2001, 2005; Guillem et al., 2001; Tendolkar et al., 2002; Kim et al., 2004), but methodological limitations and profound procedural differences impede efforts to draw general conclusions (reviewed in Kayser et al., 2009). Whereas the typical behavioral finding is poorer task performance in patients (i.e., reduced recognition accuracy, longer response latency), ERP old/new effects overlapping the late positive complex with a mid-parietal maximum were largely preserved in schizophrenia, suggesting that conscious recollection may not be impaired.
