为探讨提议者情绪预测偏差对公平决策的影响以及其中介机制,采用了两轮最后通牒博弈提议者实验任务,第一轮测量分配方案被接受和拒绝的情绪预测偏差,第二轮测量提议者的分配方案。研究结果表明:(1)提议者情绪预测偏差影响公平决策;(2)公平感知在提议者情绪预测偏差与公平决策间起部分中介作用。研究认为,提议者对积极结果的情绪预测偏差,会降低其公平感知,进而降低其分配方案公平性; 提议者对消极结果的情绪预测偏差,会提高其公平感知,进而增加其分配方案公平性。 相似文献

为探究儿童在不同利益对比情境以及与己利益无关情境中的公平行为,研究呈现了自我任务的劣势博弈、优势博弈、冲突博弈以及第三方任务博弈四种分配情境。自我任务中儿童需要为自己与另一名匿名儿童迫选方案,第三方任务中则需为两名匿名儿童迫选方案。结果发现:(1)劣势博弈中所有年龄组均倾向于选择公平方案,而非劣势方案;(2)优势博弈中,8岁、10岁组选择公平方案的人显著多于优势方案,而4岁、6岁组均无显著差异;(3)冲突博弈中,4岁、6岁组选择优势方案的人显著多于劣势方案,而8岁、10岁组均无显著差异;(4)第三方博弈中, 8岁、10岁组选择公平方案的人显著多于不公平方案,而4岁、6岁组均无显著差异。这表明,4岁~6岁儿童尚未真正获得公平观念,且以获得个人利益为主;而8岁是真正获得公平观念的转折年龄,8~10岁儿童对人对己均坚持公平原则,且表现出利他倾向。 相似文献

公平行为是儿童道德发展的重要内容。本研究采取博弈实验范式来考察学龄前儿童公平意图的发展情况。以往对儿童公平意图的博弈研究中,选取的儿童年龄跨度大且研究范式并不适应学龄前儿童的认知特点,而学龄前期可能正是公平意图开始发生及发展的时期。因此本研究选取108名4-6岁学龄前儿童,在实验一中采用独裁者博弈(DG),实验二中改进mini-最后通牒博弈(mini-UG),分别从提议者和回应者的角度考察学龄前儿童公平意图的发展情况。结果表明:4岁儿童已经能初步辨识对方的公平意图,但分配结果的公平性在他们行为决策时占的比重更大;5到6岁期间公平意图的影响更大,是儿童公平意图发展的一个关键时期。 相似文献

为探究不同卷入情境下儿童基于资源价值的分配行为特点以及内群体偏爱在其中的作用, 呈现给儿童两种实验情境:实验1, 134名5~8岁儿童在第一方情境下与来自内、外群体的一名儿童分配不同价值的物品, 结果发现7~8岁儿童公平分配比例与5~6岁儿童无显著差异; 实验2, 130名5~8岁儿童在第三方情境下给来自特定群体的两名儿童分配资源, 结果发现7~8岁儿童公平分配比例显著高于5~6岁儿童。两个实验均发现儿童的分配行为表现出内群体偏爱, 5~6岁儿童比7~8岁儿童更明显。并且, 5~6岁女生比男生有更明显的内群体偏爱, 但在7~8岁组无性别差异。此外, 只有7~8岁儿童的公平分配行为表现出卷入情境上的差异, 他们在第三方情境比第一方情境下更能做出公平分配, 但5~6岁儿童的公平分配行为并无情境差异。综上可见, 比起年幼儿童, 年长儿童基于资源价值的公平行为发展得更好, 并且在两种卷入情境下受内群体偏爱的影响均更小。 相似文献

It has been robustly demonstrated using the ultimatum game (UG) that individuals frequently reject unfair financial offers even if this results in a personal cost. One influential hypothesis for these rejections is that they reflect an emotional reaction to unfairness that overrides purely economic decision processes. In the present study, we examined whether the interplay between bodily responses, bodily regulation, and bodily perception ("interoception") contributes to emotionally driven rejection behavior on the UG. Offering support for bodily feedback theories, interoceptive accuracy moderated the relationship between changes in electrodermal activity to proposals and the behavioral rejection of such offers. Larger electrodermal responses to rejected relative to accepted offers predicted greater rejection in those with accurate interoception but were unrelated to rejection in those with poor interoception. Although cardiovascular responses during the offer period were unrelated to rejection rates, greater resting heart rate variability (linked to trait emotion regulation capacity) predicted reduced rejection rates of offers. These findings help clarify individual differences in reactions to perceived unfairness, support previous emotion regulation deficit accounts of rejection behavior, and suggest that the perception and regulation of bodily based emotional biasing signals ("gut feelings") partly shape financial decision making on the UG. 相似文献

从博弈游戏看儿童经济决策行为的发展 总被引:1,自引:0,他引:1
国外有研究借助最后通谍(UG)和独裁者博弈(DG)探查了儿童的决策行为,他们发现,随着儿童年龄的增长,他们分配给对方的金额呈上升趋势,即公平和分享行为随年龄增加。儿童的经济决策行为和社会化不可避免要受文化影响。研究探查了中国文化下小学三、六年级、初二、大学一年级四个年龄组学生在最后通谍(UG)和独裁者博弈(DG)中的经济决策行为发展。研究同时比较了个体决策和群体决策的差异。结果发现:儿童在两个博弈中的提议金额都显示出公平和分享行为,随着儿童年龄的增长,儿童在UG和随后进行的DG中的提议分配金额呈减少趋势。这个发现与以往国外研究结果明显不同。两个博弈的顺序对UG没有影响,但对DG有影响;儿童的个体决策和群体决策结果没有显示显著差异 相似文献

Two studies examined the influence of Social Value Orientation (SVO) on the decision to accept or reject an unfair offer in the Ultimatum Game (UG). In both studies, participants with different SVOs (Prosocials, Individualists and Competitors), measured about 3 weeks prior to the UG, responded to an offer of “$8 for Proposer, $2 for Participant”, believing it came from a human Proposer. In both studies Prosocials accepted the offer more frequently than Individualists and Competitors, who did not differ. Further, we found that SVO differences in positive emotions in response to the offer (Study 1), and positive cognitions toward the offer and the proposer (Study 2) underlie the SVO effect on UG decision, suggesting a role for SVO differences in the utilization of emotion regulation strategies. Implications of the present findings for “altruistic punishment” and “emotions/self-regulation” accounts as motivators of UG decisions are discussed. 相似文献

Rejection of an inequitable and yet unintended outcome in a truncated ultimatum game was examined in an experiment with 46 undergraduate students (27 men and 19 women) from a large national university in Japan. In an ultimatum game, one of two players, the proposer, makes an offer to divide a fixed-sum of money. The other player, the responder, decides whether to accept or reject the offer. When the responder rejects the proposer's offer, neither of the two players receives a reward. Previous work examining the behavior of participants in the truncated ultimatum game employed strategy method in their experimental design. We examined whether these previous findings would be replicated in an experimental design that did not use the strategy method and instead used the standard one-shot game. Seven out of 46 responders given an inequitable offer rejected it, replicating prior results with the strategy method. We further found that subjects who rejected an offer that was involuntary and yet inequitable did not over-attribute intentions to the proposer's involuntary behavior more strongly than did acceptors. These findings strongly suggest that aversion to inequity is the explanation for the subjects' rejection of the inequitable offer. 相似文献

This paper addresses the general issue of whether the practice of investigating human decision making in hypothetical choice situations is at all warranted, or under what conditions. A particularly relevant factor that affects the match between real decisions and hypothetical decisions is the importance of a decision’s consequences. In the literature experimental gambles tend to confound the reality of the decision situation with the size of the payoffs: hypothetical decisions tend to offer large payoffs, and real decisions tend to offer only small payoffs. Using the well-known framing effect (a tendency of risk-aversion for gains and of risk-seeking for losses) we find that the framing effect depends on payoff size but hypothetical choices match real choices for small as well as large payoffs. These results appear paradoxical unless size of incentive is clearly distinguished from the reality status of decision (real versus hypothetical). Since the field lacks a general theory of when hypothetical decisions match real decisions, the discussion presents an outline for developing such a theory. 相似文献

One of the key principles underlying rational models of decision making is the idea that the decision maker should never choose an action that is stochastically dominated by another action. In the study reported in this article, violations of stochastic dominance frequently occurred when the payoffs produced by two actions were negatively correlated (in conflict), but no violations occurred when the payoffs were positively correlated (no conflict). This finding is contrary to models which assume that choice probability depends on the utility of each action, and the utility for an action depends solely on its own payoffs and probabilities. This article also reports, for the first time ever, the distribution of response times observed in a risky decision task. Both the violations of stochastic dominance and the response time distributions are explained in terms of a dynamic theory of decision making called multiattribute decision field theory. 相似文献

In many everyday decisions, people quickly integrate noisy samples of information to form a preference among alternatives that offer uncertain rewards. Here, we investigated this decision process using the Flash Gambling Task (FGT), in which participants made a series of choices between a certain payoff and an uncertain alternative that produced a normal distribution of payoffs. For each choice, participants experienced the distribution of payoffs via rapid samples updated every 50 ms. We show that people can make these rapid decisions from experience and that the decision process is consistent with a sequential sampling process. Results also reveal a dissociation between these preferential decisions and equivalent perceptual decisions where participants had to determine which alternatives contained more dots on average. To account for this dissociation, we developed a sequential sampling rank-dependent utility model, which showed that participants in the FGT attended more to larger potential payoffs than participants in the perceptual task despite being given equivalent information. We discuss the implications of these findings in terms of computational models of preferential choice and a more complete understanding of experience-based decision making. 相似文献
