Duration and pitch deviants

WebWe presented a duration deviant and a pitch/duration deviant in this study. Literature has shown that duration MMN was more robust in separating controls from schizophrenia patients than pitch MMN (e.g., Magno et al. 2008). Duration deviant was therefore our primary task.
