自我信息识别优势——来自注意定向网络的证据

研究采用注意网络测验任务(attention network test, ANT), 分别检验自我相关信息在注意的警觉、定向和执行控制网络上的加工效率差异, 以揭示自我信息识别优势的注意机制。实验1考察了面孔类型(自我面孔或他人面孔)在3种注意网络下的加工效率差异; 实验2采用自我联结学习范式对实验1进行验证; 实验3将颜色类型(红色或绿色)作为目标刺激, 面孔类型作为背景, 以考察任务无关自我信息是否对注意网络加工效率有影响。研究结果发现, 当自我信息为目标时, 个体在注意定向网络上存在加工效率优势, 而警觉和执行控制网络上没有加工效率差异。当自我相关信息与任务无关时, 在注意的警觉、定向和执行控制网络中均未表现出加工效率优势。说明了自我信息的注意优势发生在注意定向网络上, 且受任务优先性影响。     

网络协作过程中团队成员信任机制的实验研究

本文采用情景模拟实验的方法,以大学生为研究对象,通过模拟现实环境中虚拟团队的工作方式,考察了虚拟团队协作过程中个体信任六个因子（风险、利益、实用价值、影响力、兴趣以及努力程度）的发展。实验历时两个月,共进行三次问卷调查,收集了不同阶段各个团队个体信任六个因子变化发展的数据。本研究运用蜘蛛图和平衡秤模型分析了积极团队和消极团队个体信任发展的差异。研究结果表明,在虚拟团队发展的早期,个人利益和兴趣是影响个体信任的主要因子,随着团队任务的进展,实用价值成为后期主要的影响因素之一;在虚拟团队发展早期,成员间可能会发生较为激烈的人际和任务冲突,并对兴趣和努力等因子产生消极的影响;相对于消极团队,积极团队更专注于团队任务,成员更乐于参与团队协作并提高自身的影响力。     

团队中信任形成的映象决策机制

有关团队管理的研究日益注重团队行为过程及其因素并聚焦团队动力机制。其中,团队中信任形成机制成为管理心理学中的前沿领域。以往研究表明,团队成员间的信任模式及其水平是高绩效工作团队的关键条件,团队中信任的形成过程受到成员的个体价值取向、人际交往能力、团队领导风格以及团队共享心理模型特征等诸多因素的影响。而团队信任形成与发展的机制,则仍然是有待深入研究的重要课题。为了进一步研究与分析团队运作机制,以映象理论为基础,采用了实验模拟方法,系统考察团队成员信任的形成过程及其关键特征,深入探索团队成员信任形成的映象决策机制。实验采用团队局域网络模拟方法和被试间因子式设计,分别设置了高目标冲突（个体目标导向）和低目标冲突（团队目标导向）等两种条件。对随机组合的20个团队进行了投资任务的实验模拟与分析,结果表明,团队成员的信任决策是一种映象决策,表现出拒绝阈限。在建立信任关系的过程中,理想映象和当前映象的加工对能力和诚信更加重视,容易导致不信任;而对善意的要求稍宽一些。团队成员在工作任务中对理想映象和当前映象之间进行相容性检验,并作出信任决策判断。在这一动态过程中,相容性知觉起着部分中介作用,形成了映象决策的机制     

不同心理一致感个体对情绪信息的注意偏向

研究采用线索-靶子任务,考察高、低心理一致感个体对情绪信息的注意偏向特点。结果显示:(1)在有效提示下,高心理一致感个体对积极情绪表现出稳定的注意警觉,对消极情绪的注意偏向不稳定,低心理一致感个体对积极和消极情绪的注意偏向均不稳定;(2)在无效提示下,高心理一致感个体对积极和消极情绪的注意回避均不稳定,而低心理一致感个体对积极情绪表现出注意回避,对消极情绪表现出注意解除困难,这些注意偏向均具有中等程度的稳定性。     

道德自我对利己和利他行为倾向的注意偏向

以大学生为被试,通过点探测任务考察高低道德自我水平对利他和利己词汇的注意偏向。结果发现:(1)高道德自我水平个体在利他-利己词语、利他-中性配对出现时,若探测点与利他词语位置一致,被试的反应时比较短,而当探测点与利他词语位置不一致时,被试的反应时会延长;(2)低道德自我水平的个体在探测点与利己词语同位时的反应时短,当探测点同利他词语或中性词语位置一致时反应时增加;(3)高道德自我水平个体对利他词语的注意偏向值为正,即存在注意警觉,而对利己词汇的注意偏向值为负,表现出注意回避;低道德自我水平个体对利己词汇也存在注意回避。结果表明道德自我水平的高低影响个体对利他和利己行为倾向的注意偏向。     

注意状态、认知方式与前瞻记忆的TAP效应

采用经典实验室研究范式,实验一探讨了前瞻记忆任务为知觉加工条件下,注意状态和前瞻记忆任务与进行中任务一致和不一致时对不同认知方式个体前瞻记忆成绩的影响,实验二探讨了前瞻记忆任务为语义加工条件下,注意状态和前瞻记忆任务与进行中任务一致和不一致时对不同认知方式个体前瞻记忆成绩的影响,结果表明,（1）在前瞻记忆任务加工类型是语义加工和知觉加工两种条件下,场依存与场独立个体均发现了TAP效应的存在,而且场依存个体表现出更明显的TAP效应;（2）当前瞻记忆任务与进行中任务的加工类型不一致时,场独立个体的前瞻记忆成绩明显高于场依存个体,而在两类任务加工类型一致情况下,场独立与场依存个体的前瞻记忆成绩不存在明显差异;（3）在前瞻记忆任务是知觉加工时,分心对前瞻记忆成绩有明显不利的影响;而在前瞻记忆任务是语义加工时,只有当前瞻记忆任务与进行中任务加工类型不一致时,分心对前瞻记忆才有明显不利的影响,而且在分心条件下的TAP效应更明显。     

冲突对绩效的影响：个体、团队宜人性的调节作用

以往个体和团队冲突研究主要考察了个人特征或团队特征对冲突结果的影响, 而尚未充分关注冲突管理过程中个体特征与团队特征间的交互效应。基于个人-团队匹配理论, 本研究探讨了个体层面宜人性与团队层面宜人性异质性对团队中个体冲突(关系冲突、任务冲突)和工作绩效间关系的影响。基于来自64个银行服务团队(包含339名下属和64名主管)的多来源、多时点纵向数据, 本研究所得结果显示：(1)关系冲突显著负向影响工作绩效, 任务冲突对工作绩效的影响不显著。(2)个体宜人性能够显著减弱关系冲突对工作绩效的负面影响, 而增强任务冲突对工作绩效的正向影响。(3)关系/任务冲突、个体宜人性和团队宜人性异质性间存在着三重交互效应, 共同影响工作绩效。具体而言, 当团队宜人性异质性水平较低时, 个体宜人性对关系/任务冲突与工作绩效间关系的调节作用更加显著。     

风险取向类型与爱荷华赌博任务成绩的影响

神经科学领域的研究者们设计了测量情感决策的经典爱荷华赌博任务并提出了体细胞标记假说来解释其研究结果,但迄今为止这一假说还没有得到一致认可。许多研究提出了可能影响爱荷华赌博任务成绩的其他因素。本研究试图在前人研究的基础上采用实验法探讨风险取向类型这一人格因素是否影响正常个体的爱荷华赌博任务成绩。实验结果显示,不同风险取向类型的个体在爱荷华赌博任务中的成绩和表现截然不同。典型风险趋向型个体在爱荷华赌博任务中的表现类似于某些神经系统患者,倾向于更多地选择不利纸牌,其任务成绩显著差于典型风险回避型个体。这一研究结果表明：风险取向类型是影响正常个体爱荷华赌博任务成绩的重要因素之一。     

虚拟团队共享式领导的双刃剑效应研究：基于调适性结构理论的视角

虚拟团队因新兴技术驱动而成为组织管理的潮流, 尤其全球疫情的爆发使得远程办公备受关注。共享式领导是与虚拟团队高度匹配的领导模式, 但现今学界对虚拟团队共享式领导作用机制的研究比较匮乏, 且集中在正面效应和团队层次, 忽略了共享式领导可能存在的负面效应及对个体层次的影响。研究基于调适性结构理论, 提出虚拟团队共享式领导有助于团队及个体内部动机和效能感的提升, 同时也会加剧团队内社会惰化现象和关系冲突水平, 引发员工的工作负荷和工作焦虑感, 进而对团队绩效和个体绩效产生双刃剑效应, 同时, 团队虚拟性、任务复杂性和任务重要性在其中起到调节作用。研究模型系统打开了虚拟团队共享式领导的影响机制黑箱, 为组织如何在虚拟情境下领导团队、提升绩效提供借鉴。     

奖赏通过增强信号监测提升认知控制

认知控制是动态的、过程性的认知调控, 涉及监测和控制两个过程。先前研究表明奖赏可以提升认知控制, 但是奖赏是通过增强信号监测来提升认知控制的, 还是作用于控制过程来提升认知控制的, 是一个有待研究的重要问题。在本研究中, 我们设计了三个实验来调查这一问题。实验1采用Stop-Signal任务验证奖赏是否能提升认知控制; 实验2通过改变反应规则将Stop-Signal任务信号监测加工分离出来, 探讨实验1中奖赏的提升作用是否来源于奖赏对信号监测的增强; 实验3通过操纵注意资源损耗分析, 考察注意资源分配对信号监测的促进作用。实验1结果显示, 个体能更快地根据奖赏信息做出抑制反应。实验2结果表明, 在信号监测任务中, 个体能更加快速地监测到与当前抑制状态相冲突且和奖赏相关的反应信号, 据此可认为奖赏通过增强对相关信号的监测, 有助于个体更早地启动奖赏刺激信号所对应的反应, 更高效地控制冲突。实验3结果说明, 当任务难度增大, 注意资源损耗, 奖赏相关信号的反应时和正确率仍优于无奖赏信号, 说明注意资源的分配可以调节相关信号的监测速度。总体来看, 本研究通过一系列实验表明, 以目标为导向的行为发生过程中, 奖赏能有效提升认知控制效率, 其关键机制在于通过注意资源分配增强相关信号的监测。     

Information search in heuristic decision making

Simple heuristics of the type introduced by Gigerenzer, Todd, and The ABC Research Group ( 1999 ) embody principles for information search, stop and decision making. These heuristics suggest that such processes are simple. In an analysis of general practitioners' (GPs) information search and decision‐making behaviour when prescribing a lipid lowering drug, we examined whether information search was simple, and whether a heuristic that predicts a simple decision‐making process was also accurate at describing information search. We found that GPs' information search behaviour was simple in that it demonstrated characteristics of the matching heuristic (e.g. stopping rule). In addition, although the matching heuristic which correctly predicted on average 75% of GPs' decisions used significantly fewer cues on average than the GPs did in the information search task, it was reasonably accurate in describing order of information search. These findings have implications for the validity of simple heuristics describing both information search and decision making. Copyright © 2009 John Wiley & Sons, Ltd.     

群体讨论过程中信息策略的变化

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。     

The influence of decision heuristics and overconfidence on multiattribute choice: A process-tracing study

In the present study it was shown that decision heuristics and confidence judgements play important roles in the building of preferences. Based on a dual-process account of thinking, the study compared people who did well versus poorly on a series of decision heuristics and overconfidence judgement tasks. The two groups were found to differ with regard to their information search behaviour in introduced multiattribute choice tasks. High performers on the judgemental tasks were less influenced in their decision processes by numerical information format (probabilities vs. frequencies) compared to low performers. They also looked at more attributes and spent more time on the multiattribute choice tasks. The results reveal that performance on decision heuristics and overconfidence tasks has a bearing both on heuristic and analytic processes in multiattribute decision making.     

Stability/Instability of Cognitive Strategies Across Tasks Determine Whether Stress Will Affect Judgmental Processes'

Previous research indicates that individuals employ various cognitive heuristics and decision modes in making decisions and judgmental tasks that do not follow an expected value model. It further indicates that several cognitive faculties are affected by stress. The purpose of this study was twofold: first, to examine whether individual differences exist in the use of cognitive heuristics and risk-assessment decision modes; second, to examine whether stress would affect the use of these cognitive strategies. Three versions of a questionnaire measuring the representativeness and availability heuristics, and risk-seeking and risk-aversion decision modes were administered to three different groups of subjects. Consistent individual differences were only observed in the subscales measuring risk-seeking and risk-aversion modes, but not in the use of the heuristics. In a different group of subjects, exposure to noise and task overload stress increased the use of the representativeness heuristic, but did not alter the use of risk-seeking and risk-aversion decision modes. These results indicate that the existence of individual differences in cognitive strategies may determine, in part, whether stress will modify judgmental processes.     

Time perception,vigilance and decision theory

A statistical decision hypothesis is outlined to account for a progressive lengthening of judgments which occurs when a series of reproductions of a time interval is made without interpolation of a standard. Three experiments are reported in which it is found that this serial effect can be manipulated by hypothetical payoff conditions, that the effect still occurs when subjects are told to count while making their judgments, and that two successive judgments are sufficient to demonstrate the effect if enough subjects are used. The phenomenon is related to recent studies of vigilance in which statistical decision theory has been applied. It is suggested that serial reproductions of time intervals may perhaps be a more sensitive index of the factors underlying vigilance than the traditional measures involving long sessions with weak, sporadic signals.     

Minority dissent and team innovation: the importance of participation in decision making.

This study integrates research on minority dissent and individual creativity, as well as team diversity and the quality of group decision making, with research on team participation in decision making. From these lines of research, it was proposed that minority dissent would predict innovation in teams but only when teams have high levels of participation in decision making. This hypothesis was tested in 2 studies, 1 involving a homogeneous sample of self-managed teams and 1 involving a heterogeneous sample of cross-functional teams. Study 1 suggested that a newly developed scale to measure minority dissent has discriminant validity. Both Study 1 and Study 2 showed more innovations under high rather than low levels of minority dissent but only when there was a high degree of participation in team decision making. It is concluded that minority dissent stimulates creativity and divergent thought, which, through participation, manifest as innovation.     

Training fast and frugal heuristics in military decision making

Fast and frugal heuristics have been used to model decision making in applied domains very effectively, suggesting that they could be used to improve applied decision making. We developed a fast and frugal heuristic for infantry decisions using experts from the British Army. This was able to predict around 80% of their decisions using three cues. Next, we examined the benefits of learning to use the fast and frugal heuristic by training junior officers in the British Army to apply the heuristic and assessing their accuracy and mental workload when making decisions. Their performance was compared to a control condition of junior officers who applied standard military decision methods. Participants using the fast and frugal heuristic made decisions as accurately as participants in the control condition, but with reduced mental demand. This demonstrates that fast and frugal heuristics can be learnt and are as effective as analytic decision methods.     

“Test-Tube Baby” procedures: Stress and judgements under uncertainty

Patients participating in an in vim fertilisation with embryo transfer (IVF and ET) programme face uncertainty at each stage of the procedure. Research on heuristics and on stress lead to predictions about behaviour in situations of uncertainty. It was predicted that IVF and ET participants would overestimate the likelihood of success, due to publicity the process has received, and would underestimate the likelihood of an earlier, less publicised. stage in the procedure. Both predictions were confirmed in a total of 70 participants (26 women at out-patient clines, 23 of their partners and 21 surgical in-patients). All the men and all but one woman overestimated the likelihood of becoming pregnant and having a baby. and most of the surgical patients underestimated the likelihood of egg recovery. Estimates were not related to patients' confidence about their information, confirming previous evidence about confidence in inaccurate judgements based on heuristics. Data on patients' distress as indicated by mood rating show high anxiety at points of uncertainty and Pailure, as found in other studies of stress. While the couples shared their inaccurate judgements. they did not necessarily share their distress. The results are discussed in terms of patients' decision making. coping strategies and the implications for doctor-patient communication.     

The role of intuition and deliberative thinking in experts' superior tactical decision-making

Current theories argue that human decision making is largely based on quick, automatic, and intuitive processes that are occasionally supplemented by slow controlled deliberation. Researchers, therefore, predominantly studied the heuristics of the automatic system in everyday decision making. Our study examines the role of slow deliberation for experts who exhibit superior decision-making outcomes in tactical chess problems with clear best moves. Our study uses advanced computer software to measure the objective value of actions preferred at the start versus the conclusion of decision making. It finds that both experts and less skilled individuals benefit significantly from extra deliberation regardless of whether the problem is easy or difficult. Our findings have important implications for the role of training for increasing decision making accuracy in many domains of expertise.     

Biases and Heuristics in Decision Making and Their Impact on Autonomy

Cognitive scientists have identified a wide range of biases and heuristics in human decision making over the past few decades. Only recently have bioethicists begun to think seriously about the implications of these findings for topics such as agency, autonomy, and consent. This article aims to provide an overview of biases and heuristics that have been identified and a framework in which to think comprehensively about the impact of them on the exercise of autonomous decision making. I analyze the impact that these biases and heuristics have on the following dimensions of autonomy: understanding, intentionality, absence of alienating or controlling influence, and match between formally autonomous preferences or decisions and actual choices or actions.
