许多移情任务由于使用简单化的刺激和静态的分析方法而缺乏生态效度。移情准确性任务通过使用自传体情感视频剪辑克服了这些限制。通常，移情准确性的单一测量是通过将参与者对叙述者情绪状态的连续评级与叙述者自己的评级相关联来计算的。在这项研究中，我们验证了一个修改的移情准确性任务。增加了叙述者情绪强度的独立价评级，以提供描绘不同主要情绪的视频之间的可比性，并探索与情绪强度随时间变化相关的神经活动变化。我们还增加了一个新的中性控制条件来研究一般的情绪处理。在扫描仪中，34名健康的参与者观看了6个人们谈论自传体事件的视频片段（2个悲伤，2个快乐和2个中性片段），同时不断评估叙述者的情绪强度。感知情绪强度的波动与先前涉及认知共情（双侧上级颞沟、颞顶交界处和颞极）和情感共情（右前额叶和额下回）的大脑区域的活动相关。当情绪化的视频片段与中性的视频片段进行比较时，我们观察到相似的大脑区域更高的活动。另一方面，移情准确性只与涉及认知移情的区域的激活呈正相关。我们改进的共情准确性任务为研究共情的潜在成分和动态过程提供了一种新的方法。虽然这项任务引起了认知和情感上的同理心，但成功地跟踪他人的情绪主要依赖于同理心的认知成分。这里开发的功能磁共振成像数据分析技术可能被证明是有价值的表征共情困难的神经基础上观察到的一系列精神疾病。情绪视频中情感和认知共情相关区域的活动。类似区域的活动与感知情绪强度的变化相关。只有涉及认知共情的区域与共情准确性相关。没有差异的视频剪辑，并没有引起影响共享。共情准确性与自我评价的观点采择相关，但与共情关注无关。
Many empathy tasks lack ecological validity due to their use of simplistic stimuli and static analytical approaches. Empathic accuracy tasks overcome these limitations by using autobiographical emotional video clips. Usually, a single measure of empathic accuracy is computed by correlating the participants' continuous ratings of the narrator's emotional state with the narrator's own ratings. In this study, we validated a modified empathic accuracy task. A valence-independent rating of the narrator's emotional intensity was added to provide comparability between videos portraying different primary emotions and to explore changes in neural activity related to variations in emotional intensity over time. We also added a new neutral control condition to investigate general emotional processing. In the scanner, 34 healthy participants watched 6 video clips of people talking about an autobiographical event (2 sad, 2 happy and 2 neutral clips) while continuously rating the narrator's emotional intensity. Fluctuation in perceived emotional intensity correlated with activity in brain regions previously implicated in cognitive empathy (bilateral superior temporal sulcus, temporoparietal junction, and temporal pole) and affective empathy (right anterior insula and inferior frontal gyrus). When emotional video clips were compared to neutral video clips, we observed higher activity in similar brain regions. Empathic accuracy, on the other hand, was only positively related to activation in regions that have been implicated in cognitive empathy. Our modified empathic accuracy task provides a new method for studying the underlying components and dynamic processes involved in empathy. While the task elicited both cognitive and affective empathy, successful tracking of others' emotions relied predominantly on the cognitive components of empathy. The fMRI data analysis techniques developed here may prove valuable in characterising the neural basis of empathic difficulties observed across a range of psychiatric conditions. Activity in affective and cognitive empathy related regions during emotional videos. Activity in similar regions related to changes in perceived emotional intensity. Only regions implicated in cognitive empathy were associated with empathic accuracy. No difference between video clips that did and did not elicit affect sharing. Empathic accuracy related to self-rated perspective-taking but not empathic concern.
