Neurocognitive Markers Of Cognitive Control In Schizophrenia And Functional Outcomes, Sephira Ryman

Psychology ETDs

Impaired cognitive function results in decreased objective quality of life and community functioning in schizophrenia, resulting in the largest indirect costs from the disease. Disrupted proactive cognitive control, a form of early selection and active goal maintenance, is hypothesized to underlie the broad cognitive deficits observed in patients with schizophrenia. The current study utilized novel electrophysiological (EEG) analytic approach to examine proactive and reactive cognitive control deficits in schizophrenia patients. Behavioral results highlight that patients exhibited a general reduction in reaction time across two multisensory cognitive control tasks, with selective deficits on proactive conditions relative to reactive conditions. The relative …
