最近的证据指出，伴随身体疼痛和社会排斥的痛苦经历背后的神经系统可能存在重叠（Eisenberger等人，2003年）。本研究测试了两个假设，即：（1）对身体疼痛的基线敏感性将预测对社会排斥的敏感性，（2）增加社会痛苦的经历也会增加对身体疼痛的敏感性。在目前的研究中，参与者的基线皮肤热痛不愉快阈值进行了评估之前完成的任务，操纵社会痛苦的感觉。在这项任务中，参与者玩了一个虚拟的投球游戏，据称是与另外两个人一起玩的，在这个游戏中，他们要么被持续地包括在内（社会包容条件），要么被排除在游戏之外，要么从未被包括在内，要么被公开地排除在外（社会排斥条件）。在游戏结束时，提供了三种疼痛刺激，参与者对每种刺激的不愉快程度进行了评分。结果表明，更大的基线疼痛敏感性（较低的疼痛不愉快阈值）与更大的自我报告的社会困扰，以应对社会拒绝条件。此外，对于那些在社会排斥条件下，更多的社会痛苦的报告与更多的报告疼痛不愉快的热刺激在游戏结束时交付。这些结果提供了额外的支持的假设，疼痛困扰和社会困扰共享神经认知基板。讨论了对临床人群的影响。(c)2006年国际疼痛研究协会。Elsevier B.V.出版，保留所有权利。
Recent evidence points to a possible overlap in the neural systems underlying the distressing experience that accompanies physical pain and social rejection (Eisenberger et al., 2003). The present study tested two hypotheses that stem from this suggested overlap, namely: (1) that baseline sensitivity to physical pain will predict sensitivity to social rejection and (2) that experiences that heighten social distress will heighten sensitivity to physical pain as well. In the current study, participants' baseline cutaneous heat pain unpleasantness thresholds were assessed prior to the completion of a task that manipulated feelings of social distress. During this task, participants played a virtual ball-tossing game, allegedly with two other individuals, in which they were either continuously included (social inclusion condition) or they were left out of the game by either never being included or by being overtly excluded (social rejection conditions). At the end of the game, three pain stimuli were delivered and participants rated the unpleasantness of each. Results indicated that greater baseline sensitivity to pain (lower pain unpleasantness thresholds) was associated with greater self-reported social distress in response to the social rejection conditions. Additionally, for those in the social rejection conditions, greater reports of social distress were associated with greater reports of pain unpleasantness to the thermal stimuli delivered at the end of the game. These results provide additional support for the hypothesis that pain distress and social distress share neurocognitive substrates. Implications for clinical Populations are discussed.
