When Hurt Will Not Heal
研究发现，重温过去的社会性疼痛比重温身体性疼痛更易引发强烈痛感，并损害后续认知任务表现，揭示了两种疼痛的重要区别。
Recent discoveries suggest that social pain is as real and intense as physical pain, and that the social-pain system may have piggybacked on the brain structure that had evolved earlier for physical pain. The present study examined an important distinction between social and physical pain: Individuals can relive and reexperience social pain more easily and more intensely than physical pain. Studies 1 and 2 showed that people reported higher levels of pain after reliving a past socially painful event than after reliving a past physically painful event. Studies 3 and 4 found, in addition, that people performed worse on cognitively demanding tasks after they relived social rather than physical pain. Implications for research on social pain and theories about social pain are discussed.
