Disembodiment and socio-emotional deficits are core features of the schizophrenia spectrum from the prodromal stages to chronic illness. A recent study documented anomalous emotional embodiment in individuals with schizophrenia. Although bodily self disturbances have been shown to precede and predict psychosis onset in at-risk populations, the etiology of anomalous emotional embodiment remains largely unexplored. The present study investigated bodily maps of emotions in relation to schizotypy to extend our understanding of embodied emotions in the schizophrenia spectrum.
A total of 419 participants (312 female; 19.50 ± 1.22 years) completed a topographical body mapping task where they reported patterns of embodiment experienced in the context of eleven different emotions and a neutral state (EmBODY). Embodied emotions were investigated in relation to multidimensional schizotypy.
Individuals with elevated negative schizotypy experienced embodied emotions with higher intensity ( = 0.16, = 0.003) but lower clarity (i.e., endorsing activation and deactivation in the same bodily location; β = -0.28, 95% CI [-0.54, -0.03], = 2.25, =0.02) and endorsed more incongruent bodily sensations of emotions (i.e., reporting bodily activation in the context of a low-arousal emotion, = 0.12, = 0.05; reporting bodily deactivation in the context of high-arousal emotions, = 0.13, = 0.02). In line with the anomalous emotional embodiment documented in individuals with schizophrenia, some of these differences were particularly notable for low-arousal emotions.
These results reveal negative schizotypy as a significant correlate of differences in emotional embodiment. More work is needed to link these differences to the anomalous bodily sensations of emotions documented in schizophrenia and assess their functional impact.
脱离身体感和社会情感缺陷是精神分裂症谱系从前驱期到慢性病阶段的核心特征。最近一项研究记录了精神分裂症患者存在异常的情感身体化现象。尽管在高危人群中，身体自我障碍已被证明先于并预测精神病发作，但其异常情感身体化的病因在很大程度上仍未得到探索。本研究调查了与精神分裂症特质相关的情感身体图谱，以扩展我们对精神分裂症谱系中情感身体化的理解。
共有419名参与者（312名女性；年龄19.50±1.22岁）完成了一项地形身体图谱任务，他们报告了在11种不同情绪和一种中性状态（EmBODY）下所体验到的身体化模式。研究了与多维精神分裂症特质相关的情感身体化。
具有较高阴性精神分裂症特质的个体体验到的情感身体化强度更高（β = 0.16，p = 0.003），但清晰度较低（即认可在同一身体部位有激活和失活；β = -0.28，95%CI[-0.54，-0.03]，t = （此处原文可能有误，推测应为t = 2.25），p = 0.02），并且认可更多不一致的情感身体感觉（即在低唤醒情绪下报告身体激活，β = 0.12，p = = 0.（此处原文可能有误，推测应为p = 0.05）；在高唤醒情绪下报告身体失活，β = 0.13，p = 0.02）。与精神分裂症患者中记录的异常情感身体化一致，其中一些差异在低唤醒情绪下尤为明显。
这些结果表明阴性精神分裂症特质是情感身体化差异的一个重要相关因素。需要更多的研究来将这些差异与精神分裂症中记录的异常情感身体感觉联系起来，并评估它们的功能影响。
