The authors comment on the article "The primacy of cognition in schizophrenia," by R. W. Heinrichs. They state that Heinrichs persuasively argued as to the primacy of cognition in schizophrenia by citing an impressive body of evidence in favor of the view that schizophrenia is a complex biobehavioral disorder that manifests itself primarily in cognition. His conclusion is something of an anticlimax. At the same time, however, he acknowledged that "the glass of evidence is half empty as well as half full" (Heinrichs, 2005, p. 238). That is to say, the symptoms that mark out schizophrenia--the hallucinations, delusions, and so forth--do not appear to map onto cognitive deficits, or at least they do not map onto those that are measured with traditional neuropsychological tests. To fill the other half of the glass, the authors propose that a focus on emotion (largely neglected in the target article) will be of crucial importance. Furthermore, they commend the methods of cognitive neuropsychiatry as being eminently suitable to guide this research. The authors briefly illustrate the value of this approach with reference to affective characteristics of hallucinations and cognitive-emotional interactions in source monitoring.
