高功能孤独症儿童的合作行为

合作行为是一种重要的亲社会行为, 对儿童的社会适应具有重要意义, 而孤独症儿童的典型特征是社会功能存在缺陷, 从而导致合作行为的缺乏。以往研究未能就孤独症儿童在不同合作任务类型中的表现做出区分, 本研究采用经典的囚徒困境博弈和合作性工具任务比较了6~12岁的高功能孤独症儿童和正常发展儿童在不同任务中的合作行为。结果显示高功能孤独症儿童和正常儿童在囚徒困境中的合作行为没有显著差异, 然而, 他们在工具性任务中表现出比正常儿童更低水平的合作行为。这说明高功能孤独症儿童在对认知能力有不同要求的合作任务中的表现不同。     

从归因视角探讨公共物品两难中惩罚系统对合作的影响

社会两难中惩罚系统对合作的影响是当前的一个研究热点。前人研究发现惩罚系统可以促进合作,但也有学者提出惩罚系统对合作动机具有破坏作用,存在不一致结论。且这些研究大多只关注金钱惩罚而忽略了社会惩罚。本文采用2(惩罚类型:金钱,社会)×2(惩罚频率:高,低)×2(阶段:有惩罚,无惩罚)混合设计,利用"惩罚撤除"实验范式,比较了社会高低频惩罚和金钱高低频惩罚对合作、归因以及预期的影响。并探讨了合作、归因、预期之间的相互关系,结果发现:(1)金钱和社会惩罚均可提高被试合作水平;(2)金钱高频惩罚减少了对合作行为的内归因,惩罚撤除后合作行为下降,而低频惩罚没有出现下降效应;(3)社会惩罚增加了对合作的内归因,高低频惩罚在移除之后均保持较高水平,且之前的惩罚频率越高,保持效果越好;(4)合作、预期与内归因正相关,外归因负相关,同时合作与预期正相关。     

HOW SHOULD WE BEHAVE? A REVIEW OF REASONS AND PERSONS BY DEREK PARFIT

In this book Parfit attempts to develop a rational, non-religious ethics. Instead of asking, “What does God tell us to do?” he asks, “What does reason tell us to do?” Given a set of simple assumptions, he considers whether it is possible to be consistently selfish or consistently good. Analyses of personal dilemmas (problems of self-control) and moral dilemmas (problems of social cooperation) show that neither consistent selfishness nor consistent goodness is logically possible. Instead, a fine balance must be maintained between, on the one hand, our immediate versus long-term good and, on the other, our own good versus that of other people. Ultimately Parfit fails to develop a formula by which such a balance may be struck. Parfit''s analysis is consistent with behavioral analysis in its reductionistic view of the self and the parallel it draws between relations with other people and relations with oneself at other times. Parfit''s analysis is inconsistent with behaviorism in its view of the mind as internal, available to introspection, and able to cause behavior. His nonfunctional mentalism leads Parfit to inconsistencies and blocks the path to a consistent ethics. Teleological behaviorism''s view of the mind in terms of patterns of overt behavior is not hampered by these inconsistencies and may lead to a functional rather than purely rational ethics.     

社会两难行为理性特点的实验分析

本研究运用定量和定性的方法探讨了动态适应性学习条件下两难行为的理性特点及其影响因素。72名杭州本科生参加了本实验,结果发现:1、在有限次重复的两难博弈实验中,人们的两难行为不符合纳什博弈理论,进一步的定性分析指出,这种两难行为体现出“社会理性”的特征;2、在高奖罚的条件下,人们更容易做出接近“纳什均衡点”决策;3、群体规模和反馈方式对人们的对策行为影响不显著,但是,进一步的定性分析部分支持了群体规模的社会理性解释。     

Explanations of interindividual – intergroup discontinuity: A review of the evidence

The authors review and evaluate various explanations for the tendency of intergroup relations to be more competitive, or less cooperative, than interindividual relations (the discontinuity effect). They distinguish between two general perspectives, each comprising a set of explanations for the discontinuity effect. The fear and greed perspective assumes that intergroup relations are characterised by greater fear and greed than are interindividual relations. The group decision-making perspective assumes a crucial role for group discussion in facilitating rational comprehension of mixed-motive situations. In general, explanations from the fear and greed perspective were found to be more consistent with the empirical record than explanations from the group decision-making perspective. The authors propose that a complete understanding of the discontinuity effect is yet to be achieved.
