Responses of schizophrenics to expressions of the fundamental emotions

Judgment of emotion among chronic schizophrenics

“…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. The studies that have included both males and females as Ss have utilized normal populations, but, more importantly, reveal conflicting evidence as to sex differences in the accuracy of perception of emotion (e.g., Drag & Shaw, 1967;Howell & Jorgenson, 1970;Kozel, 1969).…”

“…The results reveal a significant difference between the patient and the normal group ( F = 90.53, df 1/60, p < .OOl); normal Ss were more accurate in their judgments of the EPs than were patients. These results are consistent with and extend the data reported by Dougherty, Bartlett, and Izard (1974) for female schizophrenics and indicate that male, as well as female, chronic schizophrenics are significantly less accurate in identifying the EPs for both open-ended (OE) and multiple-choice (MC) responses, which differed significantly from one another ( F = 30.24, df 1/60, p < .001). A S X OE vs. MC interaction also was observed ( F = 12.25, df 1/60, p < .001).…”

Typicality range deficit in schizophrenics' recognition of emotion in faces

“…Joy and shame were selected as the two emotion categories for this study because schizophrenics have been found to recognize joy most accurately and shame and disgust least accurately (Dougherty et al, 1974). Using joy and shame, schizophrenic typicality ratings can be compared for an accurately recognized category and for a poorly recognized category.…”

“…Would they see more joy and fewer shame expressions than would normals? Schizophrenics make more errors on shame expressions and more often recognize an expression as joy when it is some other emotion (Dougherty et al, 1974). These two issues, anchoring and category boundary shift, were assessed for each group and were stated in three hypotheses.…”

A Compensatory Mirror Cortical Mechanism for Facial Affect Processing in Schizophrenia

“…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.…”
