Canadian researchers found that a brainwave associated with “recognition of incongruent speech” differed according to whether the person listening to such speech was told that the speaker was diagnosed with schizophrenia. The brainwave was absent when the person was told that the speaker had been diagnosed with schizophrenia. “Such responses to abnormal speech in schizophrenia indicate an expectation of abnormality from individuals with schizophrenia,” say the authors, “which has implications for understanding social exclusion of individuals with the disorder.” Results appeared online in Schizophrenia Research.
