![]() ![]() Negative symptoms in schizophrenia, such as blunted affect, alogia, asociality, anhedonia, and avolition, remain challenging to treat in many patients, but new concepts may lead to a better understanding of the definition and treatment of these symptoms. The characterization of flat affect as a purely emotional deficit is questioned, and limitations of current neuropsychological theories of emotional expression and neuropsychological methods to test these theories in the study of schizophrenia are discussed as relevant concerns for future research.Developing Concepts in Negative Symptoms: Primary vs Secondary and Apathy vs Expression The results thus failed to support for the proposed neuropsychological models of affective deficits in schizophrenia. Despite the fact that schizophrenia subjects demonstrated significantly higher clinical ratings of affective flattening and less facial expression while viewing films than demographically matched control subjects, neuropsychological performance was not consistently related to these expressive deficits. Furthermore, deficits in affective expression were assessed both in a clinical interview and in subjects' response to affect-eliciting films. The advantages of the present study were that unmedicated schizophrenia patients were studied and relevant demographic characteristics were controlled. This study evaluated the association between neuropsychological indices of frontal lobe and right hemisphere impairment and deficits in the expression of affect in schizophrenia.
