社會價值取向反映了人們對自己和他人分配結果的一種穩定偏好,影響著個體對提議公平性的認知及規范執行。同時,自我-他人決策差異也是影響規范執行的重要因素,但目前尚不清楚價值取向和社會距離如何影響公平規范執行。本研究選取了20名合作者和20名個人主義者,使用單次匿名最后通牒博弈任務,考察了資產分配情景中價值取向對自我-他人決策時公平規范執行的影響。結果表明:(1)相比自我決策條件,合作者在替他人決策時更多的接受不公平提議,而公平提議的接受率不受社會距離的調節;個人主義者的提議接受率則不受社會距離和提議類型的交互影響;(2)合作者替他人決策時的接受閾限顯著高于自我決策,而個人主義者在自我決策和替他人決策時的接受閾限無顯著差異。這些結果表明價值取向能夠調節自我-他人決策時,人們對不公平提議的規范執行。

Social value orientation(SVO) refers to a preference for particular patterns of outcomes for self in relation to others in situations of interdependence, and can affect individual’s perception and reaction to unfairness. Meanwhile, the self-other decision making is another important factor influencing people’s norm enforcement. However, it is still unclear how SVO and social distance influence people’s reaction to unfairness. The present study investigated whether social distance and social value orientation influences individual’s fairness norm enforcement during a one-shot Ultimatum Game(UG). Forty adults with two different SVO types participated had to accept or reject a series of 10 ultimatum offers for themselves and strangers respectively. The results showed that1) compared to deciding for themselves, cooperators accepted more unfair offer when deciding for strangers, yet individualists made similar decisions in both conditions. 2) cooperators’ acceptance threshold was higher when deciding for themselves than for strangers, while individualists had similar fair standard in both conditions. These finding suggests that SVO moderates the effect of self-others decision on responses to low ultimatum offers.
