Moral emotions elicited in response to others' suffering are mediated by empathy and affect how we respond to their pain. South Africa provides a unique opportunity to study group processes given its racially divided past. The present study seeks insights into aspects of the moral brain by investigating behavioral and functional MRI responses of White and Black South Africans who lived through apartheid to in- and out-group physical and social pain. Whereas the physical pain task featured faces expressing dynamic suffering, the social pain task featured victims of apartheid violence from the South African Truth and Reconciliation Commission to elicit heartfelt emotion. Black participants' behavioral responses were suggestive of in-group favoritism, whereas White participants' responses were apparently egalitarian. However, all participants showed significant in-group biases in activation in the amygdala (physical pain), as well as areas involved in mental state representation, including the precuneus, temporoparietal junction (TPJ) and frontal pole (physical and social pain). Additionally, Black participants reacted with heightened moral indignation to own-race suffering, whereas White participants reacted with heightened shame to Black suffering, which was associated with blunted neural empathic responding. These findings provide ecologically valid insights into some behavioral and brain processes involved in complex moral situations.
因他人受苦而引发的道德情感由同理心介导,并影响我们对他们痛苦的反应方式。鉴于南非过去存在种族隔离,它为研究群体过程提供了一个独特的机会。本研究通过调查经历过种族隔离的南非白人和黑人对群体内和群体外身体及社会痛苦的行为和功能性磁共振成像反应,来探寻道德大脑的相关方面。身体疼痛任务中呈现的是表达动态痛苦的面孔,而社会疼痛任务中呈现的是南非真相与和解委员会记录的种族隔离暴力受害者,以引发真挚情感。黑人参与者的行为反应显示出群体内偏袒,而白人参与者的反应显然更为平等。然而,所有参与者在杏仁核(身体疼痛)以及涉及心理状态表征的区域,包括楔前叶、颞顶联合区(TPJ)和额极(身体和社会疼痛)的激活上都表现出显著的群体内偏见。此外,黑人参与者对本种族的痛苦反应出更高的道德义愤,而白人参与者对黑人的痛苦反应出更高的羞耻感,这与减弱的神经共情反应相关。这些发现为复杂道德情境中涉及的一些行为和大脑过程提供了具有生态学效度的见解。
