Our fMRI study compares the neural correlates of face-based mindreading in healthy individuals with an empathizing (n=12) versus systemizing cognitive style (n=12). The empathizing group consists of individuals that score high on empathizing and low on systemizing, while the systemizing group consists of individuals with an opposite cognitive pattern. We hypothesize that the empathizing group will show stronger simulation-type neural activity (e.g., in mirror neuron areas, medial prefrontal cortex, anterior cingulate cortex) or simulation-related neural activity (e.g., in areas involved in perspective taking and experiential processing) compared to the systemizing group. As hypothesized, our study reveals that the empathizing group shows significantly stronger activity in mirror neuron areas of the brain, such as the left inferior frontal gyrus and inferior parietal lobe, and in temporal areas involved in perspective taking and autobiographical memory. Moreover, the empathizing group, but not the systemizing group, shows activity in the medial prefrontal cortex and anterior cingulate cortex which have been related to simulation-type neural activity in the brain and are central to mindreading. Also, the systemizing group shows significantly stronger activity in the left parahippocampal gyrus. In conclusion, both the empathizing and systemizing individuals show simulation-type and simulation-related neural activity during face-based mindreading. However, more neural activity indicative of simulation-based processing is seen in the empathizing individuals, while more neural activity indicative of non-simulation-based processing is seen in the systemizing individuals.
我们的 fMRI 研究比较了健康个体在基于面孔的心理理论任务中的神经相关性,这些个体具有共情(n=12)与系统认知风格(n=12)。共情组由共情得分高、系统得分低的个体组成,而系统组则由具有相反认知模式的个体组成。我们假设共情组会表现出更强的模拟型神经活动(例如,镜像神经元区域、内侧前额叶皮质、前扣带皮质)或与模拟相关的神经活动(例如,参与视角采择和体验处理的区域),与系统组相比。正如假设的那样,我们的研究表明,共情组在大脑的镜像神经元区域(例如左额下回和下顶叶)以及参与视角采择和自传体记忆的颞区表现出明显更强的活动。此外,共情组而非系统组在与大脑中模拟型神经活动相关的内侧前额叶皮质和前扣带皮质中表现出活动,这些区域是心理理论的核心。此外,系统组在左海马旁回表现出明显更强的活动。总之,共情和系统个体在基于面孔的心理理论任务中都表现出模拟型和与模拟相关的神经活动。然而,共情个体表现出更多指示基于模拟的处理的神经活动,而系统个体则表现出更多指示非基于模拟的处理的神经活动。
