“…This pattern of ERP deficits permits specific hypotheses to be developed concerning brain processes underlying impaired visual sensory processing in schizophrenia. The normal amplitude of the visual N1 observed in our study is consistent with the results of prior VEP studies on schizophrenia 42 and distinguishes visual N1, which is normal in schizophrenia, from auditory N1, which is reduced. 43 Therefore, a consistent finding in the visual system in schizophrenia may be that the initial stages of ventral stream processing are intact, whereas later stages are impaired.…”

“…Although reduced P3s are often found to auditory target stimuli in schizophrenic patients, the evidence for reduced P3 amplitude in response to visual oddball stimuli is less consistent (Kochi et al 1996;Shelley et al 1996;Wagner et al 1989). We have previously reported that the P3 to visual oddball stimuli is reduced in psychopaths relative to nonpsychopaths (Kiehl et al 1999b); however, most of these studies employed "oddball" paradigms, in which the salience of the target stimuli is very different from the Go stimuli in this experiment.…”

“…That the late positive component to the fourth standard in a row had the same scalp distribution as the P3a to a novel sound supports the contribution of orienting to the positivity elicited by Standard #4. However, arguing against a failure of the orienting response in schizophrenia are reports of normal P300s in patients to isolated targets (Roth, Goodale, & Pfefferbaum, 1991; Shelley, Grochowski, Lieberman, & Javitt, 1996) and startling noises (Ford, Roth, Menon, & Pfefferbaum, 1999) that occur at very long inter-target intervals with no intervening standards, a situation likely to elicit orienting. Instead, we suggest that patients with schizophrenia fail to use context to form expectations about pattern violations.…”
