    对疼痛的同理心是利他行为的基础,并且已知受群体成员等变量的调节,情境和社会关系的愉快或不愉快。此外,在痛苦的条件下观察一个人时,面部吸引力和审美判断可能会发挥作用,通过增加个人的移情反应。的确,身体吸引力可以改变面部本身的感知及其在社会环境中的接收。在本研究中,当注意力集中在表现出痛苦感觉的个体的美学特征上时,我们旨在评估皮质活动。大脑活动(光学成像:功能近红外光谱,fNIRS),当22名受试者(Mage=24.9;SD=3.6)观察到接受疼痛刺激(疼痛;无痛)的面部(有吸引力;无吸引力),并被要求判断面部的吸引力和疼痛状况时,监测其血液动力学成分(氧合[oxy-Hb]和脱氧血红蛋白[deoxy-Hb]).具体来说,我们瞄准了左右额下回(IFG),感觉皮层,和颞顶叶交界处(TPJ)。分析显示,当要求参与者独立于刺激特征对面部吸引力进行评分时,与右半球通道相比,左IFG中的oxy-Hb水平显着降低。此外,与有吸引力的面孔相比,在右侧TPJ中检测到缺乏吸引力的面孔的脱氧-Hb水平较低.总的来说,目前的研究结果强调,审美判断和面部吸引力的形成在移情问题中起着相关的作用,这似乎能够覆盖痛苦的评估。
    Empathy for pain is at the basis of altruistic behaviors and is known to be modulated by variables such as group membership, pleasantness or unpleasantness of situations and social relationships. Also, face attractiveness and aesthetic judgment might play a role when observing a person in painful conditions, by increasing individuals\' empathic responsiveness. Indeed, physical attractiveness can modify both the perception of the face itself and its reception in a social context. In the present study, we aimed to assess cortical activity when attention is focused on the aesthetic features of an individual showing painful feelings. Brain activity (optical imaging: functional near-infrared spectroscopy, fNIRS), considered in its hemodynamic components (oxygenated [oxy-Hb] and deoxygenated hemoglobin [deoxy-Hb]) was monitored when 22 subjects (Mage = 24.9; SD = 3.6) observed faces (attractive; unattractive) that received painful stimulations (pain; no pain) and were asked to judge the attractiveness and pain condition of the face. Specifically, we targeted the left and right inferior frontal gyrus (IFG), sensory cortex, and temporo-parietal junction (TPJ). Analyses revealed significant lower oxy-Hb levels in left IFG compared to right hemispheric channels when asking participants to rate faces attractiveness independently from the stimulus features. Besides, lower levels of deoxy-Hb were detected in the right TPJ for unattractive faces compared to attractive faces. Overall, present findings highlighted that the formulation of an aesthetic judgment and face attractiveness plays a relevant role in empathic concerns and this seems to be able to overlay painful appraisal.
