本研究的目的是探讨限制性厌食症患者的身体自我，重点关注与身体自我相关的两个基本方面：社会行为中的自主策略，其中他人的社会期望特征，以及社会线索（例如，凝视）被调节，并且内感受（即，对源自体内的刺激的敏感性）。此外，由于以前对健康个体进行的研究发现，内感受似乎有助于社会行为的自主调节，如呼吸窦心律失常（RSA）所测量的，我们的目的是探索厌食症患者的这种联系，他们感知身体信号的能力似乎受损。为了这个目的，我们比较了一组厌食症患者（ANg;限制型）与一组健康对照（HCG）的RSA反应在休息状态和社会化学任务，他们明确的判断舒适的社会距离在行为化学任务，和他们的内感受准确性（IA）。结果表明，ANg显示出显着较低的社会倾向和平坦的自主反应过程中的化学任务，不考虑他人的社会理想的功能或社会线索的存在。此外，与HCG不同，ANg的自主觉醒并不指导社交距离的行为判断。最后，IA在两组中与社会倾向严格相关，但ANg的趋势相反。我们的结论是，自主神经失调及其改变与内感受的关系可能有厌食症的障碍中发挥了至关重要的作用。
The aim of this study is to investigate the bodily-self in Restrictive Anorexia, focusing on two basic aspects related to the bodily self: autonomic strategies in social behavior, in which others' social desirability features, and social cues (e.g., gaze) are modulated, and interoception (i.e., the sensitivity to stimuli originating inside the body). Furthermore, since previous studies carried out on healthy individuals found that interoception seems to contribute to the autonomic regulation of social behavior, as measured by Respiratory Sinus Arrhythmia (RSA), we aimed to explore this link in anorexia patients, whose ability to perceive their bodily signal seems to be impaired. To this purpose, we compared a group of anorexia patients (ANg; restrictive type) with a group of Healthy Controls (HCg) for RSA responses during both a resting state and a social proxemics task, for their explicit judgments of comfort in social distances during a behavioral proxemics task, and for their Interoceptive Accuracy (IA). The results showed that ANg displayed significantly lower social disposition and a flattened autonomic reactivity during the proxemics task, irrespective of the presence of others' socially desirable features or social cues. Moreover, unlike HCg, the autonomic arousal of ANg did not guide behavioral judgments of social distances. Finally, IA was strictly related to social disposition in both groups, but with opposite trends in ANg. We conclude that autonomic imbalance and its altered relationship with interoception might have a crucial role in anorexia disturbances.
