摘要
采用信任博弈任务创设人际信任、人际背叛及背叛后利他惩罚三种人际情境,探讨三种人际情境对不同任务难度工作记忆的影响。结果发现:(1)随着工作记忆的难度增加,三组正确率均显著下降。在低难度任务中,人际信任组和背叛后利他惩罚组正确率均高于人际背叛组;中等难度任务中,人际信任组正确率高于背叛后利他惩罚组和人际背叛组;高难度任务中,三组正确率无明显差异;(2)随着工作记忆的难度增加,三组反应时均显著增加。低难度任务中,人际信任组、背叛后利他惩罚组反应时均低于人际背叛组;中等难度和高难度任务中,三组反应时无明显差异。结论:人际信任、人际背叛及背叛后利他惩罚对工作记忆有不同作用。
To investigate the effects of interpersonal context on working memory （WM）, participants first underwent one of the three interpersonal situations （ interpersonal trust, interpersonal betrayal and altruistic punishment after the betrayal） in trust game task and then performed an N-Back WM task. The results showed that： （1） the accuracies of N-back WM task decreased significantly with the increase of task difficulty. In addition, in the 1 -back condition, the accuracies of interpersonal trust and altruistic punishment after the betrayal were higher than that of interpersonal be- trayal; in the 2-back condition, the accuracy of interpersonal trust was higher than that of interpersonal betrayal and altruistic punishment after the betrayal; in the 3-back condition, there were no significant differences between groups ; （2） the reaction time became significantly longer with the increase of the task difficulty. In the 1-back condi- tion, the reaction time of interpersonal trust and altruistic punishment after the betrayal was lower than that of inter- personal betrayal; in the 2-back and 3-back condition, no significant difference was found across groups. These re- suits suggested that the effect of interpersonal experiences on WM performance is modulated by task difficulty.
