Impaired anticipatory event-related potentials in schizophrenia.
Deficits in anticipation are implicated across a variety of cognitive and emotional processes in schizophrenia. Although diminished anticipatory event-related potentials (ERPs) have been detected during tasks requiring motor response preparation in schizophrenia, no prior ERP study has examined non-motor-related anticipatory processes or used motivationally engaging stimuli. Thirty-four schizop...
متن کاملEvent-related potentials, cognition, and behavior: a biological approach.
The prevailing cognitive-psychological accounts of event-related brain potentials (ERPs) assume that ERP components manifest information processing operations leading from stimulus to response. Since this view encounters numerous difficulties already analyzed in previous studies, an alternative view is presented here that regards cortical control of behavior as a repetitive sensorimotor cycle c...
متن کاملSubstantial shared genetic influences on schizophrenia and event-related potentials.
OBJECTIVE Several components of event-related potentials--P50 suppression, P300 amplitude and latency, and mismatch negativity--have been proposed as potential endophenotypes for schizophrenia on the basis of family studies. The present study used a twin design to estimate the extent of genetic overlap between these indices and the liability to schizophrenia. METHOD The authors measured misma...
متن کاملInformation dysregulation and event-related potentials in schizophrenia.
Clinical experiences indicate that schizophrenic cognitive disturbances may be partly due to the unsuccessful construction of their cognitive context. In this article, two experiments are introduced in which schizophrenic deficits in utilization of information for construction of effective cognitive context were examined through measurements of event-related potentials, particularly P300s. In a...
متن کاملSemantic bias, homograph comprehension, and event-related potentials in schizophrenia.
OBJECTIVES It is controversial whether a semantic processing bias for strong associates is present in schizophrenia, and unknown whether the language abnormalities observed in schizophrenia can be attributed to dysfunctions early or late in cognitive processing. Combined behavioral and event-related potential (ERP) data can indicate the nature and timing of such abnormalities. METHODS Sensibi...
