Affect Judgement and Facial Recognition Memory in Schizophrenia

Two experiments are described in which the performance of schizophrenic subjects was investigated, using tests of affect judgement and recognition memory for faces (Warrington), words, and semi-abstract patterns. Schizophrenic subjects were impaired in their ability to describe the emotional states portrayed by actors and presented on video and were more likely to comment on the physical description of the actor or to fail to comment on the emotion at all. Performance on the Warrington Recognition Memory Test for faces suggests a marked impairment in schizophrenia, although impaired performance on recognition memory tests for words and patterns indicates that this abnormality may not be specific for faces.

“…Numerous reports over the last forty years (reviewed in Hellewell and Whittaker 1998) indicate that patients with schizophrenia have a deficit in properly recognizing facial affect-the emotional value aspects of facial expressions (Borod et al 1993;Streit et al 1997;Addington and Addington 1998;Federman et al 1998;Habel et al 2000;Izard 1959;Dougherty et al 1974;Muzekari and Bates 1977;Walker et al 1980;Heimberg et al 1992;Iscoe and Veldman 1963;Pillowski and Bassett 1980). Yet the neural correlates of these deficits have not been established.…”

“…The few published studies that compared schizophrenics and normals on accuracy of perception of emotional stimuli have been limited primarily to judgment of gross affect along a happiness-unhappiness (Levy, Orr, & Rosenzweig, 1960) or a favorable-unfavorable (Izard, 1959) continuum and included only acute male patients as Ss. Dougherty, Bartlett, and Izard (1974) published the most comprehensive study of responses of schizophrenics to emotional expressions from still photographs; however, they sampled female patients only.…”

This study investigated accuracy of judgment as to posed facial expressions and nonverbal scenes of various emotions. Ss were 16 male and 16 female chronic schizophrenics and a normal control group of equal size and sex composition. The results revealed that normal Ss were significantly more accurate than schizophrenics in identifying emotions from both posed photographs of the face and nonverbal videotape scenes. S sex was not found to affect differentially the schizophrenic or normal Ss' response accuracy to both the photographs and videotapes. Further, it was observed that both groups' accuracy improved when given multiple-choice alternatives to select from as contrasted to their open-ended free responses; this was especially true for the schizophrenic group. Teaching patients to identify and practice expressing discrete emotions was suggested.
