亲社会性行为及其社会偏好的分解

Prosocial Behaviors and the Decomposition of Social Preferences

本文通过结合一个被试内设计的双人匿名且完全陌生搭配的"四合一"实验和调查问卷,首先论证了四种经典亲社会性行为的广泛存在性,并发现这几种亲社会行为两两之间均显著相关;同时我们对信任博弈实验中的投资和回报行为以及公共品博弈中的投资行为进行了社会偏好的分解和检验,发现信任博弈中的信任投资行为受互惠偏好的显著影响,而可信任回报行为受到纯粹利他偏好和互惠偏好的双重影响;同时公共品博弈实验中的投资行为受到差异厌恶偏好的显著影响。

Employing a within-subjects design, in this paper we run a two-person anonymous and absolutely strange matching quaternate experiments with suvery questions. We found there are widely exsited with four kinds of classic prosocial behaviors and we also detected a significant relations between these different kinds of prosoeial behaviors in different games. Meanwhile we decomposed and tested the social preferences behind the trust and trustworthiness actions in the trust game and the cooperation actions in the public goods game. We found that the variance in trust actions is accounted for by expectation of trustworthiness but not altruism, while variance in trustworthiness actions is mainly accounted for by altruism with a comparatively small role of reciprocity. And the pattern of cooperation behavior in public goods game is consistent with inequality aversion.
