摘要: Objective: Embodied emotions arise from interoceptive and somatosensory processes, and are essential to the development of a stable sense of self. Emotional embodiment is therefore inherently interwoven with our sense of bodily self-awareness, and allows us to navigate complex social situations. Given that the core nature of schizophrenia is characterized by the presence of bodily self-disturbances and social-emotional deficits, we hypothesized that embodiment of emotion would be disrupted in schizophrenia.Method: Twenty-six medicated individuals with schizophrenia and 26 demographicallymatched controls used a computerized topographical mapping tool (“EmBODY”) to indicate on a body outline where they felt bodily sensations while experiencing an emotion. There were 13 different emotions plus a neutral state. The resulting bodily maps of emotions were quantitatively compared between groups using linear discriminant analysis and similarity scores.Results: Bodily maps of emotions were anomalous in schizophrenia as indicated by indistinguishable bodily maps across different emotions. Relative to the control group, patients reported less discrete and less clear bodily sensations across emotions. In particular, bodily maps for low-arousal emotions were atypical in comparison with healthy controls.Conclusions: Anomalous and undifferentiated mapping of embodied emotions in schizophrenia could lead to deficits in linking bodily sensations to conceptual categories of emotions. Disrupted emotional embodiment could also contribute to the poor social functioning. Abnormal bodily sensations of emotions might therefore be a …
