Key Points

  • This research aims to investigate how social value orientation affects source memory during reciprocal cooperation.
  • Utilized a sequential prisoner’s dilemma paradigm combined with behavioral and EEG experiments.
  • Evaluated source memory for cooperative and betrayal partners based on individual social value orientations.
  • Measured event-related potentials (FRN and LPP) and theta oscillations during feedback processing.
  • Pro-social individuals exhibited better source memory for cooperation, while egoistic individuals had superior memory for betrayal sources.
  • Egoistic individuals displayed greater FRN amplitude to betrayal feedback during early evaluation stages.
  • Only egoistic individuals showed larger LPP amplitudes and stronger theta oscillations in response to betrayal feedback.

Abstract

摘要： 本研究采用序列囚徒困境范式, 结合行为与脑电实验探究社会价值取向对互惠合作中合作与背叛伙伴来源记忆的影响及其电生理机制。行为结果发现, 亲社会价值取向者对合作伙伴有更好的来源记忆, 而亲自我价值取向者对背叛伙伴有更好的来源记忆。脑电结果发现, 在结果评价早期阶段, 亲自我价值取向者在背叛反馈下诱发更大FRN波幅, 而亲社会价值取向者在合作反馈下诱发更大FRN波幅; 在晚期阶段, 仅亲自我价值取向者在背叛反馈下诱发更大LPP波幅及更强的theta振荡。结果表明不同社会价值取向个体对合作与背叛反馈出现相反的结果评价模式, 仅亲自我价值取向者对背叛反馈存在更高情绪唤醒并投入更多注意资源。此外, FRN波幅和theta振荡均与来源记忆正确率显著相关。综上, 社会价值取向通过调节互惠合作中的结果评价过程, 进而影响个体对合作与背叛伙伴的来源记忆偏好。
