Aims: The Mismatch negativity (MMN) is an event-related potential (ERP) which provides an index of automatic context-dependent information processing and auditory sensory memory. MMN studies using traditional „oddball“ paradigms (e.g. 80% standards, 20% deviants) replicated deficits in preattentive information processing especially in schizophrenia. In a so-called „optimum“ paradigm with only 50% standards but 50% deviants (Näätänen et al. 2003) MMN responses are still maintained but assessment time is considerably shortened with advantage of investigating several deviants simultaneously. The present study compa…
