Flat affect in schizophrenia does not reflect diminished subjective experience of emotion.

Although accorded historical significance, affective features of schizophrenia have only begun to receive systematic empirical attention. Interestingly, both early psychopathology writers and more recent investigators have reported frequent discrepancies between schizophrenics' feelings and outward expressions of emotion. Using a more comprehensive assessment of emotion, the present study examines the relationship between emotional experience and expression in a sample of medication-free schizophrenics. Compared with their normal counterparts, schizophrenics were indeed much less facially expressive of both positive and negative emotions during emotion-eliciting films, yet they reported experiencing as much positive and negative emotion. Therefore, the blunted affect typical of some schizophrenics misrepresents their underlying emotional experience. Future research into an inhibition hypothesis is recommended.

The Facial Expression Coding System (FACES): Development, validation, and utility.

This article presents information on the development and validation of the Facial Expression Coding System (FACES; A. M. Kring & D. Sloan, 1991). Grounded in a dimensional model of emotion, FACES provides information on the valence (positive, negative) of facial expressive behavior. In 5 studies, reliability and validity data from 13 diverse samples, including students, psychiatric patients, and community adults, are presented, and results indicate that raters can reliably agree on instances of positive and negative expressive behavior. Validity studies indicate that FACES ratings are related in predictable ways to another observational coding system, facial muscle activity, individual-difference measures of expressiveness and personality, skin conductance, heart rate, and reports of experienced emotion. FACES can be a useful tool for assessing expressive behavior in a variety of contexts. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Just teasing: A conceptual analysis and empirical review.

Drawing on E. Goffman's concepts of face and strategic interaction, the authors define a tease as a playful provocation in which one person comments on something relevant to the target. This approach encompasses the diverse behaviors labeled teasing, clarifies previous ambiguities, differentiates teasing from related practices, and suggests how teasing can lead to hostile or affiliative outcomes. The authors then integrate studies of the content of teasing. Studies indicate that norm violations and conflict prompt teasing. With development, children tease in playful ways, particularly around the ages of 11 and 12 years, and understand and enjoy teasing more. Finally, consistent with hypotheses concerning contextual variation in face concerns, teasing is more frequent and hostile when initiated by high-status and familiar others and men, although gender differences are smaller than assumed. The authors conclude by discussing how teasing varies according to individual differences and culture. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

More evidence for generalized poor performance in facial emotion perception in schizophrenia.

Previous studies showing that schizophrenic patients have a deficit in the ability to perceive facial expressions of emotion in others often have not used a differential deficit design and standardized measures of emotion perception. Using standardized and cross-validated measures in a differential deficit design, S. L. Kerr and J. M. Neale (see record 1993-29687-001) found no evidence for a deficit specific to emotion perception among unmedicated schizophrenic patients. The present study replicated and extended the findings of Kerr and Neale in a sample of medicated schizophrenic patients. Results showed that medicated patients performed more poorly than controls overall; however, they performed no worse on facial emotion perception tasks than on a matched control task. These findings support Kerr and Neale's conclusion that schizophrenic patients do not have a differential deficit in facial emotion perception ability. Future research should examine the nature of schizophrenic patients generalized poor performance on tests of facial emotion perception.

Do schizophrenic patients show a disjunctive relationship among expressive, experiential, and psychophysiological components of emotion?

Recent research has found a discrepancy between schizophrenic patients' outward expression of emotion and their reported emotional experience. In this study, which attempts to replicate and extend the findings of previous studies, participants with and without schizophrenia viewed emotional film clips while their facial expressions were videotaped and skin conductance was recorded. Participants also reported their subjective experience of emotion following each film. Those with schizophrenia were less facially expressive than controls during the emotional films and reported experiencing as much positive and negative emotion, replicating previous findings. Additionally, schizophrenic patients exhibited greater skin conductance reactivity to all films than controls. These findings suggest a disjunction among emotional response domains for schizophrenic patients; alternative explanations for the findings are considered as well as suggestions for future research.

Individual differences in dispositional expressiveness: Development and validation of the Emotional Expressivity Scale.

Although emotional expressivity figures prominently in several theories of psychological and physical functioning, limitations of currently available measurement techniques impede precise and economical testing of these theories. The 1 7-item Emotional Expressivity Scale (EES) was designed as a self-report measure of the extent to which people outwardly display their emotions. Reliability studies showed the EES to be an internally consistent and stable individual-difference measure. Validational studies established initial convergent and discriminant validities, a moderate relationship between self-rated and other-rated expression, and correspondence between self-report and laboratory-measured expressiveness using both college student and community populations. The potential for the EES to promote and integrate findings across diverse areas of research is discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Narrating emotional events in schizophrenia.

Research has indicated that schizophrenia patients report similar amounts of experienced emotion in response to emotional material compared with nonpatients. However, less is known about how schizophrenia patients describe and make sense of their emotional life events. We adopted a narrative approach to investigate schizophrenia patients' renderings of their emotional life experiences. In Study 1, patients' (n = 42) positive and negative narratives were similarly personal, tellable, engaged, and appropriate. However, negative narratives were less grammatically clear than positive narratives, and positive narratives were more likely to involve other people than negative narratives. In Study 2, emotional (positive and negative) narratives were less tellable and detached, yet more linear and social compared with neutral narratives for both schizophrenia patients (n = 24) and healthy controls (n = 19). However, patients' narratives about emotional life events were less appropriate to context and less linear, and patients' narratives, whether emotional or not, were less tellable and more detached compared with controls' narratives. Although schizophrenia patients are capable of recounting life events that trigger different emotions, the telling of these life events is fraught with difficulty.

Electrophysiological correlates of emotional responding in schizophrenia.

People with schizophrenia consistently report normal levels of pleasant emotion when exposed to evocative stimuli, suggesting intact consummatory pleasure. However, little is known about the neural correlates and time course of emotion in schizophrenia. This study used a well-validated affective picture viewing task that elicits a characteristic pattern of event-related potentials (ERPs) from early to later processing stages (i.e., P1, P2, P3, and late positive potentials [LPPs]). Thirty-eight stabilized outpatients with schizophrenia and 36 healthy controls viewed standardized pleasant, unpleasant, and neutral pictures while ERPs were recorded and subsequently rated their emotional responses to the stimuli. Patients and controls responded to the pictures similarly in terms of their valence ratings, as well as the initial ERP components (P1, P2, and P3). However, at the later LPP component (500–1,000 ms), patients displayed diminished electrophysiological discrimination between pleasant versus neutral stimuli. This pattern suggests that patients demonstrated normal self-reported emotional experience and intact initial sensory processing of and resource allocation to emotional stimuli. However, they showed a disruption in a later component associated with sustained attentional processing of emotional stimuli. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

The role of gender differences in the reduction of etiologic heterogeneity in schizophrenia

Recent research has shown a resurgence of interest in the study of gender differences in schizophrenia. Accumulated evidence suggests that, compared with women, men have a higher incidence of schizophrenia, earlier age of onset, poorer course and medication response, poorer premorbid social and intellectual functioning, fewer affective symptoms, lower family morbid risk of schizophrenia and affective disorders, more evidence of obstetric complications in their mothers, and greater structural brain abnormalities. The roles of estrogen, neurodevelopment, and family history of affective disorder are evaluated as co-contributors to the observed gender differences in schizophrenia. Particular emphasis is given to evaluating the hypothesis that men are more prone to a hypothesized poor-prognosis, neurodevelopmental subtype of schizophrenia, for which early environmental brain insults play an important etiologic role, whereas women may be more prone to a hypothesized good-prognosis, affective subtype that is genetically related to the affective disorders. This hypothesis is evaluated in terms of (a) its ability to account for gender differences in schizophrenia, (b) its ability to link differences in clinical presentation to proposed differences in etiology; and (c) its potential to generate testable predictions for future schizophrenia research.     

Who attains social status? Effects of personality and physical attractiveness in social groups.

One of the most important goals and outcomes of social life is to attain status in the groups to which we belong. Such face-to-face status is defined by the amount of respect, influence, and prominence each member enjoys in the eyes of the others. Three studies investigated personological determinants of status in social groups (fraternity, sorority, and dormitory), relating the Big Five personality traits and physical attractiveness to peer ratings of status. High Extraversion substantially predicted elevated status for both sexes. High Neuroticism, incompatible with male gender norms, predicted lower status in men. None of the other Big Five traits predicted status. These effects were independent of attractiveness, which predicted higher status only in men. Contrary to previous claims, women's status ordering was just as stable as men's but emerged later. Discussion focuses on personological pathways to attaining status and on potential mediators.
