Abstract

Several studies in political psychology reported higher levels of empathy among political leftists (i.e. liberals) as compared to political rightists (i.e. conservatives). Yet, all those studies lean on self-reports, which are often limited by subjective bias and conformity to social norms. Here, we tested this putative asymmetry using neuroimaging: we recorded oscillatory neural activity using magnetoencephalography while 55 participants completed a well-validated neuroimaging paradigm for empathy to vicarious suffering. The findings revealed a typical rhythmic alpha-band 'empathy response' in the temporal-parietal junction. This neural empathy response was significantly stronger in the leftist than in the rightist group. In addition to this dichotomous division, the neural response was parametrically associated with both self-reported political inclination and right-wing ideological values. This is the first study to reveal an asymmetry in the neural empathy response as a function of political ideology. The findings reported in this study are in line with the current literature in political psychology and provide a novel neural perspective to support the ideological asymmetry in empathy. This study opens new vistas for addressing questions in political psychology by using neuroimaging.

意识形态价值观与移情神经对替代痛苦的反应参数相关。
政治心理学的几项研究表明,政治左派(即自由派)比政治右派(即保守派)有更高的同理心水平。然而,所有这些研究都依赖于自我报告,而自我报告往往受到主观偏见和对社会规范的遵从的限制。在这里,我们使用神经成像来测试这种假定的不对称性:我们使用脑磁图记录振荡神经活动,同时55名参与者完成了一个经过验证的神经成像范式,用于对替代性痛苦的共情。研究结果显示,在颞-顶叶交界处有一种典型的有节奏的α带“共情反应”。这种神经共情反应在左派中明显强于右派。除了这种二分法之外,神经反应还与自我报告的政治倾向和右翼意识形态价值观参数化相关。这是第一个揭示神经共情反应作为政治意识形态函数的不对称性的研究。本研究结果与当前政治心理学文献一致,为共情的意识形态不对称提供了新的神经学视角。这项研究为利用神经成像技术解决政治心理学中的问题开辟了新的前景。

期刊介绍: SCAN will consider research that uses neuroimaging (fMRI, MRI, PET, EEG, MEG), neuropsychological patient studies, animal lesion studies, single-cell recording, pharmacological perturbation, and transcranial magnetic stimulation. SCAN will also consider submissions that examine the mediational role of neural processes in linking social phenomena to physiological, neuroendocrine, immunological, developmental, and genetic processes. Additionally, SCAN will publish papers that address issues of mental and physical health as they relate to social and affective processes (e.g., autism, anxiety disorders, depression, stress, effects of child rearing) as long as cognitive neuroscience methods are used.
