"Impaired emotional functioning is a core feature of schizophrenia described by Eugen Bleuler (1911)nearly 100 years ago. Emotional abnormalities in schizophrenia are now receiving more attention by clinicians and investigators and include a variety of symptoms such as flat or constricted affect, inappropriate affect, and depression (Kohler et al., 2000a). In addition to negative symptoms' influence on the experience and expression of emotions, there is evidence that schizophrenia patients are impaired in recognizing and discriminating facial emotions (Morrison et al., 1988; Mandal et al., 1998; Edwards et al., 2001; Kohler et al., 2003). It is unclear whether emotion recognition deficits represent a specific or generalized form of cognitive impairment in schizophrenia (Kerr and Neale, 1993; Whittaker et al., 2001), yet recent studies show that emotion processing deficits are uniquely related to clinical symptoms (Kohler et al., 2000b; Silver et al., 2002; Sachs et al., 2004)."
