连续性公共物品困境中信息结构对决策行为的影响 总被引:3,自引:0,他引:3
选取240名大学二年级的学生,通过局域网信息反馈,进行了模拟投资的小组实验。结果发现,1、在连续性公共物品困境和自协调序列规则下,先前决策者的合作行为在决策的早期和中期起到了明显的榜样示范作用,并导致后续决策者的合作行为增加;2、这种示范作用在决策后期不起作用,被试出于搭便车或者担心自己利益受损的心理会表现出较高的竞争行为;3、先前决策者的竞争行为在整个决策过程中都起到明显的示范作用,使后续决策者的合作率保持在较低的水平;4、在没有任何信息反馈的情况下,被试倾向于在初期就做出投资决策,并表现出一定程度的合作行为。 相似文献

4项实验探讨了共同经历相同负性情绪事件,相比单独经历负性情绪事件,是否以及如何促进了个体间的合作。实验1~3分别采用抽奖任务和瑞文推理测验任务操纵负性情绪事件,采用公共物品博弈任务测量合作行为,结果表明,共同经历相同负性情绪事件,相比单独经历负性情绪事件,促进了个体间的合作行为。实验2通过测量归属需要、社会联结和内群体认同,实验3通过操纵归属需要,来考察共同经历相同负性情绪事件促进合作行为的潜在机制,结果表明,共同经历者之间的合作行为受归属需要的驱动,而社会联结和内群体认同不足以对该现象进行解释。实验4通过操纵个体共同经历“相同”和“不同”的负性情绪事件,进一步厘清了,促进个体间的合作是由于“共同经历相同的负性情绪事件”而非“共同经历负性情绪”造成的。研究结果有利于解释小群体的形成,对群体和社会管理亦具有借鉴意义。 相似文献

个人影响力在群体决策整合过程中的作用:对SDS理论的扩展 总被引:4,自引:0,他引:4
以往社会决策图式理论没有考虑决策群体中成员的地位、成员的价值取向和专长知识分布等决策者影响力因素对群体决策整合过程的影响。本文在考虑上述诸因素影响的前提下构建了决策者影响力函数,通过投资决策模拟实验,综合使用决策影响力函数和个体偏好分布来预测群体决策的结果。研究表明综合运用决策者影响力函数和修改后的社会决策图式理论比传统的理论能更准确和有效的预测群体决策。 相似文献

呈现眼睛特征的图片就能使人的行为发生变化的现象称为眼睛效应。眼睛效应存在于多种社会现象中, 合作行为中的眼睛效应已被多种实验证明, 其原理可从声誉机制、规则机制、奖惩机制及认知机制等视角予以解释。眼睛效应的发生受在场他人、任务类型、个体公众意识及群体身份、线索呈现方式等因素的限制。目前有关眼睛效应的稳定性仍存在较多争议, 未来需要从性别和文化等个体或群体差异、脑生理机制、社会应用价值等方面进行深入研究。 相似文献

群体讨论过程中信息策略的变化 总被引:2,自引:0,他引:2
启发式是人类决策的重要特征,然而对于群体分布式加工条件下的启发式研究却是一个困难的任务。本研究利用多特征多选择决策任务与过程跟踪技术,对群体讨论条件下的启发式决策特点进行研究。结果发现,在群体讨论情景下,决策者的信息呈现策略要更加完全,但决策者的信息搜索负荷并没有因此而增加,群体的各成员之间形成了信息策略上的分布式加工,所以在群体工作情景中的表现出相互依赖性与内隐加工机制。 相似文献

This article introduces a creative approach to family enrichment. The program emphasizes educational skill-building techniques using nontherapuetic approaches that enable families to resolve difficulties of family members. The meetings, which employ coaching and videotape feedback, enable parents and children to practice communication, cooperation, and problem-solving skills. Evaluation results indicate that participants become successful in the home environment as a result of their involvement in the multiple-family, group-training sessions. 相似文献

The effects of type of feedback and base rate on threshold learning in a multiple‐cue decision task were examined. In most such decision experiments, participants receive feedback after every trial (full feedback), and a single base rate (usually 0.5) is used. Our experiment explored conditional feedback (feedback only after positive decisions) representing common selection and detection tasks (such as hiring), where the decision maker receives no feedback unless the decision is positive (e.g., hire the applicant). We used three base rates (0.2, 0.5, and 0.8). As expected, performance was best in full feedback, but after 300 learning trials, the difference was small. Conditional feedback generally resulted in fewer positive decisions than full feedback, but this difference was not found in the low (0.2) base rate condition. There were interactions between base rates and types of feedback. Results provide partial support for the constructivist encoding hypothesis of Elwin and colleagues. Simulation results suggest that our results may reflect overconfidence when feedback is not given. With respect to rate of learning, when the base rate was 0.2, conditional feedback participants reached approximately the same selection rate but did so more slowly than the full feedback participants. Partial feedback participants learned slower and appeared to be still learning after 500 trials. When the base rate was 0.5 or 0.8, partial feedback was nearly as good as full feedback, but conditional feedback resulted in a systematically lower rate of positive decisions.

Detection and Selection Decisions with Conditional Feedback: Interaction of Task Uncertainty and Base Rate 下载免费PDF全文
Effects of task uncertainty on decision thresholds in a multiple cue decision task were examined under two types of feedback and three base rate conditions. In most such decision experiments, participants receive feedback after every trial (full feedback) with a single (usually .5) base rate. Our experiment explored conditional (decision‐contingent) feedback, in a task representing a detection problem (passenger screening) in which the decision maker receives no feedback unless the decision is positive (search the passenger). Increased uncertainty made all dependent measures worse. Task uncertainty had detrimental effects on both judgment and decision making, and interacted with effects of feedback and base rate. Decision performance was better with full feedback than with conditional feedback, but not by much. There may be no single unifying explanation for results of our base rate manipulation. Conditional feedback generally resulted in fewer positive decisions than full feedback, but not in the low (.1) base rate condition. Results provide partial support for constructivist encoding and for accuracy maximization with moderate and high base rates, but not with a low base rate. Our results indicated lower selection rates with conditional feedback compared with full feedback in moderate and high base rate conditions, and a more exploratory strategy with higher selection rates with conditional feedback compared with full feedback when base rate was low.

A social dilemma is a situation in which members of a group are faced with a conflict between maximizing personal interests and maximizing collective interests. Communication among the members of a group has been shown to enhance cooperation (maximize groups interests); it was hypothesized that if members are allowed to make a pledge prior to their actual decision, they can communicate their intentions and hence increase the cooperation rate. Two experiments were conducted in which several types of pledge conditions were contrasted with a "no-pledge" (control) condition. As hypothesized, the results indicate that a pledge enhanced cooperation. However, the degree of commitment required in the pledge differentially affected the cooperation rate. The results are interpreted in terms of a two-stage dilemma in which members can coordinate their expectations only if some degree of commitment is required in their pledge. 相似文献

Through an analysis of a feedback session among members of a small task-oriented group, the multifaceted nature of feedback was explored. Dynamism, trust, clarity, mood, and criticism emerged as important underlying dimensions of peer feedback. Additionally, this study explored the communicator style in giving feedback. Significant communicative differences across group members were found in their manner of giving feedback. Effectiveness of feedback was significantly related to the feedback's dynamism and with a verbally assertive style. This study appears to demonstrate that both feedback content and form influence judgments of feedback effectiveness. 相似文献

The study explored whether cooperation could be promoted by identification with an in-group. A game was used to create two groups independent of each other. Thirty-six Japanese undergraduate students participated in the game, followed by a social dilemma game. Analysis revealed a two-factor structure of social identification: identification with the group and identification with its members. As predicted from social identity theory, subjects showed a significantly higher level of cooperation when the dilemma game was played with in-group members than with out-group members. Furthermore, identification with the group affected both in-group bias and cooperative behavior in the social dilemma game, but this effect was not found for identification with members. 相似文献

采用Chicken Game博弈任务,考察了不同社会价值取向个体(亲社会者与亲自我者)在面对不同社会距离的博弈对手(朋友和陌生人)时表现出的合作与冲突行为。研究结果发现:(1)社会价值取向与社会距离交互影响个体的合作与冲突行为;(2)社会价值取向影响选择策略的反应时,亲社会者选择合作的反应时长于选择冲突的反应时,亲自我者选择合作与选择冲突的反应时没有显著差异;(3)无论对亲社会者还是亲自我者,反馈类型都显著影响个体的合作与冲突行为的选择率以及随后决策的反应时。上述结果表明,个体的合作或冲突行为,并非单一地受到社会价值取向的影响,更可能是受到个人因素(社会价值取向)与其他社会因素(比如,社会距离)的共同调节,并且在这一过程中个体会根据决策后反馈信息不断的调整自己的行为策略。 相似文献

Interindividual-intergroup discontinuity is the tendency, in mixed-motive situations, for groups to interact more competitively,
or less cooperatively, than individuals, even though mutual competition yields worse results that mutual cooperation. The
present laboratory experiment attempted to assess whether the discontinuity effect could be reduced by the establishment of
an intergroup cooperative tradition. Cooperation between intact pairs of groups was induced by placing in each group confederates
who successfully convinced their fellow group members of the long-term advantage of trust and cooperation. On subsequent blocks
of trails, the confederate was replaced by an actual subject, and then each of the original subjects was replaced so as to
simulate generational turnover. By the time all initial members were replaced, their level of cooperation had eroded to the
level of groups never experiencing mutual cooperation. The results are discussed in the context of other means of reducing
discontinuity.

This study examines the role of individual team members' positive mood and perceived team feedback for their team-directed learning behaviour. Results obtained in a sample of 186 members from 27 work teams showed that positive mood was positively associated with team-directed learning behaviour if individual members perceived that the feedback they received was based on the performance of the team as a whole, but not if they perceived such team feedback to be lacking. Moreover, teams were found to be more innovative to the extent that their members, on average, engaged in team-directed learning behaviour to a greater extent. These results offer new insights into the micro-foundations of team learning. Our findings explicate why the contributions of individual members to their team's learning may differ and suggest that, if managed effectively, members' positive mood may be an important resource in facilitating team learning. 相似文献
