运动决策中的无意识思维研究

本研究以81名篮球专业的大学生为被试,通过决策篮球视频,考察运动决策中的无意识思维效应。实验1探讨了不同运动决策信息下的无意识思维决策差异,发现呈现直觉性决策信息时,无意识思维组的决策效果好于意识思维组。实验2在无意识思维阶段通过启动被试的加工方式,考察直觉性决策信息下,启动不同的加工方式对运动决策的无意识思维效应的影响,发现整体加工组的无意识思维决策效果最佳。研究结果表明,直觉性决策信息下,启动被试的整体加工方式,其无意识思维的决策效果会有所提升。     

认知闭合需要与预期后悔对个体职业决策过程的影响

本研究旨在探讨认知闭合需要(NFCC)与预期后悔(AR)对个体职业决策过程的影响。基于两种预期后悔启动方式,采用2(高NFCC,低NFCC)×2(不启动AR,启动AR)的两因素被试间设计完成了两个单独实验。结果表明:(1)不同NFCC个体的职业决策过程存在显著差异,NFCC高的个体付出的认知努力更少;(2)预期后悔显著影响个体的职业决策过程,启动预期后悔条件下个体表现出更为谨慎的决策过程;(3)预期后悔能有效缓冲高NFCC个体的认知闭合过程。     

跨期选择和风险决策的认知神经机制

经济决策包含两个传统问题：跨期选择和风险决策。跨期选择分为冲动决策和自我控制,当冲动决策时,优先激活了与中脑多巴胺神经元相联系的旁边缘区域,包括伏隔核、眶额皮层中部和前额叶中部;自我控制即选择延迟决策时大脑双侧前额叶和后顶叶皮层神经活动增强。在风险和不确定性条件下,大脑皮层和杏仁核与风险决策联系密切。     

情绪智力及相关变量对职业决策线索加工的影响

以66名应届或往届大学生为被试,运用何小蕾（2004）修订的情绪智力量表和信息板技术探讨了决策时限、选项数量及情绪智力对职业决策过程中线索加工的影响。结果发现：（1）决策时限和选项数量影响职业决策过程中各条线索的平均点击次数和平均加工时间,说明完成信息板任务过程中被试加工线索的策略会因为决策时限和选项数量的变化而发生改变;（2）情绪智力水平对职业决策中的信息搜索模式有显著影响,高情绪智力水平者倾向于采用基于选项的复杂搜索策略;（3）情绪智力的各维度对职业决策中信息加工的平均决策时间、搜索深度和搜索模式具有不同的影响,其中管理情绪、表达情绪对决策时间和搜索深度均有显著影响,理解情绪对决策时间有显著影响,利用情绪对搜索深度和搜索模式有显著影响,而情绪发展对决策时间有显著影响。     

决策信心的认知机制与神经基础

决策信心是指在进行判断或决策时, 个体对其决策最优性或正确性的信心程度。决策信心的单过程理论认为决策与信心评估是并行的同一加工过程; 而决策后理论认为决策和信心评估是串行的两个加工过程。决策信心存在两种典型的偏差效应：过分自信和信心不足。决策信心的神经机制研究指出, 信心评估可能是决策过程中最基本并且普遍存在的一个成分; 对决策信心评估敏感的脑区包括扣带回、背外侧前额叶和顶上小叶等。未来研究应该在决策信心产生的机制、信心与决策如何交互的心理及神经机制等领域展开大量研究。     

早发型重度子痫前期的诊疗决策

早发型重度予痫前期可采取保守治疗恰当延长孕龄,减少因胎儿不成熟导致的围生儿死亡。但对妊娠28周～32周以前者的保守治疗,应采取非常慎重的态度,可以预期结局作为临床决策依据,恰当把握终止妊娠的时机与指征,达到提高胎儿有效成活率,避免孕产妇终末脏器不可逆损害,降低孕产妇病死率与婴幼儿死亡及病残率,减轻家庭和社会负担的目的。     

Testing sociometer theory: Self-esteem and the importance of acceptance for social decision-making

The present study examined the sociometer’s role in guiding social behavior. The authors hypothesized that low self-esteem people (LSEs), but not high self-esteem people (HSEs), base their social decision-making on acceptance. Undergraduate participants were invited to join a social group and were led to believe that acceptance either was guaranteed, or was likely but not guaranteed. HSEs always were eager to join the group, whereas LSEs were keen to join the group only when acceptance was guaranteed. Furthermore, mediation analyses indicated that LSEs’ willingness to join the group was dependent on their anticipated social outcomes, which were contingent on acceptance from the group, whereas acceptance did not affect HSEs’ decision-making. These results support a sociometer account of social decision-making.     

Combining scenario planning and multi-criteria decision analysis in practice

The integrated use of scenario planning and multi-criteria decision analysis (MCDA) has been advocated as a powerful combination for providing decision support in strategic decisions. Scenario planning helps decision makers in devising strategies and thinking about possible future scenarios; while MCDA can support an in-depth performance evaluation of each strategy, as well as in the design of more robust and better options. One of the frameworks proposed recently, by Goodwin & Wright, suggests the use of scenario planning with multi-attribute value theory, a mathematically simple, yet extensively researched and widely employed multi-criteria method. However, so far, such framework has been presented only using hypothetical problems. In this paper, we describe two case studies where this approach was used to support real-world strategic decisions. We discuss the challenges and limitations we encountered in applying it and suggest some possible improvements that could be made to such framework. Copyright © 2007 John Wiley & Sons, Ltd.     

A dynamic objective–subjective structure for forest management focusing on environmental issues

In this paper a decision-making process is applied to a Chilean forestry firm that must deal with a host of environmental variables as well as profit making. At the core of this process is a ‘dynamic objective–subjective structure’ founded on the approach that decision making is about comprehending the preferences of the various parties involved and expanding the set of alternatives open to the decision makers. This is in contrast to many models that aim at finding the ‘best alternative’ and to decision analysis approaches that focus on presenting preferences via value functions. The paper describes in chronological order, following the sessions of a decision-making process, how the various components of the structure emerged. In doing so it demonstrates how the process led to an understanding of the real effects of dealing with the environment and how comprehending the preferences led to the introduction of new decision variables.

多决策方法多交流方式的群体决策比较

采用人员选拔的实验室模拟实验,以160名被试组成40个4人群体,对4种决策方法和2类交流方式的群体决策进行了比较。结果发现（1）决策方法和交流方式对于讨论过程的信息交流具有显著影响;（2）以计算机为中介进行决策的被试知觉到的任务难度要高于面对面决策条件;决策方法对于群体成员有关实验任务难度知觉具有主效应;交流方式和决策方法对于群体决策过程满意感和结果满意感没有显著影响;（3）在以投票轮次来表明群体达成一致意见所需时间上,决策方法对于投票轮次具有显著影响。恶魔式辩护、辨证式查询两种方法下所需的投票轮次多于专家意见法和自由讨论法的投票轮次。
