    • Event-related potentials elicited during a context-free homograph task in normal versus schizophrenic subjects 

      Salisbury, Dean F.; O, Brian F.; McCarley, Robert William; Nestor, Paul Gerard; Shenton, Martha Elizabeth (Wiley-Blackwell, 2000)
      Thought disorder in schizophrenia may involve abnormal semantic activation or faulty working memory maintenance. Event-related potentials (ERPs) were recorded while sentences reading “THE NOUN WAS ADJECTIVE/VERB” were ...

    • Patients With Mild Alzheimer's Disease Attribute Conceptual Fluency to Prior Experience 

      Wolk, David A.; Schacter, Daniel L.; Berman, Alyssa R.; Holcomb, Phillip J.; Daffner, Kirk; Budson, Andrew E. (Elsevier BV, 2005)
      Patients with Alzheimer's disease (AD) have been found to be relatively dependent on familiarity in their recognition memory judgments. Conceptual fluency has been argued to be an important basis of familiarity. This study ...

    • Prediction Signatures in the Brain: Semantic Pre-Activation during Language Comprehension 

      Maess, Burkhard; Mamashli, Fahimeh; Obleser, Jonas; Helle, Liisa; Friederici, Angela D. (Frontiers Media S.A., 2016)
      There is broad agreement that context-based predictions facilitate lexical-semantic processing. A robust index of semantic prediction during language comprehension is an evoked response, known as the N400, whose amplitude ...

    • Processing sentence context in women with schizotypal personality disorder: An ERP study 

      Niznikiewicz, Margaret A.; Friedman, Michelle; Shenton, Martha Elizabeth; Voglmaier, Martina M.; Nestor, Paul Gerard; Frumin, Melissa; Seidman, Larry Joel; Sutton, Johnathan; McCarley, Robert William (Wiley-Blackwell, 2004)
      Accumulating evidence suggests that schizophrenic patients do not use context efficiently. Also, studies suggest similarities in clinical and cognitive profiles between schizophrenic and schizotypal personality disorder ...

    • Semantic bias, homograph comprehension, and event-related potentials in schizophrenia 

      Salisbury, Dean F; Shenton, Martha Elizabeth; Nestor, Paul Gerard; McCarley, Robert William (Elsevier BV, 2002)
      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 ...
