Perceiving others in pain generally leads to empathic concern, consisting of both emotional and cognitive processes. Empathy deficits have been considered as an element contributing to social difficulties in individuals with autism spectrum disorders (ASD). Here, we used functional magnetic resonance imaging and short video clips of facial expressions of people experiencing pain to examine the neural substrates underlying the spontaneous empathic response to pain in autism. Thirty-eight adolescents and adults of normal intelligence diagnosed with ASD and 35 matched controls participated in the study. In contrast to general assumptions, we found no significant differences in brain activation between ASD individuals and controls during the perception of pain experienced by others. Both groups showed similar levels of activation in areas associated with pain sharing, evidencing the presence of emotional empathy and emotional contagion in participants with autism as well as in controls. Differences between groups could be observed at a more liberal statistical threshold, and revealed increased activations in areas involved in cognitive reappraisal in ASD participants compared with controls. Scores of emotional empathy were positively correlated with brain activation in areas involved in embodiment of pain in ASD group only. Our findings show that simulation mechanisms involved in emotional empathy are preserved in high-functioning individuals with autism, and suggest that increased reappraisal may have a role in their apparent lack of caring behavior.
感知他人处于痛苦中通常会引发共情关注,这包括情感和认知过程。共情缺陷被认为是导致自闭症谱系障碍(ASD)个体社交困难的一个因素。在此,我们使用功能磁共振成像以及表现出疼痛的人的面部表情短视频,来研究自闭症患者对疼痛的自发共情反应背后的神经基础。38名被诊断患有ASD的智力正常的青少年和成年人以及35名匹配的对照组参与了这项研究。与一般假设相反,我们发现,在感知他人经历的疼痛时,ASD个体和对照组之间的大脑激活没有显著差异。两组在与疼痛共享相关的区域表现出相似的激活水平,这证明自闭症患者和对照组中都存在情感共情和情绪感染。在更宽松的统计阈值下可以观察到两组之间的差异,结果显示,与对照组相比,ASD参与者中参与认知重新评估的区域激活增加。仅在ASD组中,情感共情得分与参与疼痛体现的区域的大脑激活呈正相关。我们的研究结果表明,情感共情中涉及的模拟机制在高功能自闭症个体中得以保留,并表明增强的重新评估可能在他们明显缺乏关爱行为中起作用。
