et al., 1999, 2001, 2009; Alain et al., 2001, 2002; Umbricht et al., 2006). A cursory inspection of the CSD waveforms suggested that the previously reported reductions in patients were also present in the current data, and we will address in a different report to what extent these reductions may be task-specific and how this may relate to impairments of later old/new effects. Likewise, our prior study (Kayser et al., 2009) also reported marked reductions of a mid-frontal, response-related sink in schizophrenia indicative of a prominent performance monitoring deficit. Additional response-locked analyses are planned to investigate whether the current data can replicate this interesting finding.
