People with stigmatized characteristics tend to be devalued by others in a given society. The negative experiences related to stigma cause individuals to struggle as they would if they were in physical pain and bring various negative outcomes in the way that physical pain does. However, it is unclear whether stigma related to one's identity would affect their perception of physical pain. To address this issue, using sexism-related paradigms, we found that females had reduced pain threshold/tolerance in the Cold Pressor Test (Experiment 1) and an increased rating for nociceptive laser stimuli with fixed intensity (Experiment 2). Additionally, we observed that there was a larger laser-evoked N1, an early laser-evoked P2, and a larger magnitude of low-frequency component in laser-evoked potentials (LEPs) in the stigma condition than in the control condition (Experiment 3). Our study provides behavioral and electrophysiological evidence that sexism-related stigma affects the pain perception of females.
具有污名特征的人往往会在特定社会中被他人贬低。与污名相关的负面经历会导致个体像遭受身体疼痛一样感到痛苦，并带来与身体疼痛相同的各种负面后果。然而，目前尚不清楚与个人身份相关的污名将如何影响他们对身体疼痛的感知。为了解决这个问题，我们使用与性别歧视相关的范式发现，女性在冷压测试（实验 1）中的疼痛阈值/耐受力降低，并且对固定强度的伤害性激光刺激的评价增加（实验 2）。此外，我们观察到在耻辱条件下，激光诱发电位（LEP）中的 N1 早期激光诱发电位（N1）、早期激光诱发电位（P2）和低频成分的幅度更大（实验 3）。我们的研究提供了行为和电生理证据，表明与性别歧视相关的污名将影响女性的疼痛感知。
