选项数量和属性重要性对决策中信息加工的影响

本研究采用决策过程研究方法中的信息板技术,以现实生活中的职业选择作为决策任务,考察了选项数量和选项属性的重要性对决策过程中信息加工的影响方式。结果表明:选项数量对决策过程的信息搜索深度、搜索模式和策略的补偿性产生了影响;选项属性的重要性并不影响决策者对属性的查看时间,但影响了决策者对属性的点击次数。     

Regret in Decision Making

Decision research has only recently started to take seriously the role of emotions in choices and decisions. Regret is the emotion that has received the most attention. In this article, we sample a number of the initial regret studies from psychology and economics, and trace some of the complexities and contradictions to which they led. We then sketch a new theory, decision justification theory (DJT), which synthesizes several apparently conflicting findings. DJT postulates two core components of decision–related regret, one associated with the (comparative) evaluation of the outcome, the other with the feeling of self–blame for having made a poor choice. We reinterpret several existing studies in DJT terms. We then report some new studies that directly tested (and support) DJT, and propose a number of research issues that follow from this new approach to regret.     

当前临床决策的问题及对策

腹主动脉瘤的外科治疗决策

腹主动脉瘤破裂是最常见、最凶险的疾病之一。提高对其治疗的临床决策水平至关重要。比较传统开腹修复治疗和血管腔内修复治疗的优缺点,以最佳证据为指导,选出最佳方案应用于临床实践。以人为本,做出科学决策,从而降低医疗费用及提高疗效及患者生活质量。     

浅析当前临床科学决策的几个影响因素

随着循证医学在我国的发展和"医疗举证责任倒置"等相关法律的实施,我国临床医生在进行诊治决策时已逐步向临床科学决策迈进。而防御性医疗、不健全的医疗制度及相关法律等却严重影响着这一科学决策的转变过程。只有有效解决了导致干扰科学决策的各种社会影响因素,如扩大基本医疗保险的覆盖率,实施医疗风险保险制度,提高医务人员认知和职业素质,保障行医安全等,临床科学决策的真正落实就大有希望。     

多维视野下的临床决策

Information Integration in Juror Decision Making

Research applying information integration theory to jury decision making has long assumed that people average informational scale values when making legal judgments. Although often consistent with research results, this hypothesis has never been tested in a legal context against a more general additive rule. The present paper describes two studies conducted as a critical test between these two models. Incriminating evidence and eyewitness confidence were varied in a full-factorial, within-subjects design involving a total of 131 subjects acting as mock jurors. Subject responses included eyewitness accuracy and defendant-guilt probability estimates, as well as final verdict decisions. Results strongly support an averaging model of legal decision making. Additional results concerning the influence of initial attitudes and the interrelationships between the variables considered are reported and their implications are discussed.     

信息模糊：消费决策领域中的有限理性

信息模糊（obfuscation）是行为经济学研究的重要领域,主要解释了在商品买卖过程中,销售商通过把商品信息复杂化等手段,让人们的消费过程变得更加复杂和困难,从而使消费者在购买商品时面对信息模糊做出种种不明智的选择的现象问题。本文从以往的研究成果出发,就信息模糊、有限理性和销售者的决策行为的关系进行了探讨,以期为信息模糊的跨学科研究提供可借鉴的思路和方法。     

Multiple Systems in Decision Making: A Neurocomputational Perspective

ABSTRACT— Various psychological models posit the existence of two systems that contribute to decision making. The first system is bottom-up, automatic, intuitive, emotional, and implicit, while the second system is top-down, controlled, deliberative, and explicit. It has become increasingly evident that this dichotomy is both too simplistic and too vague. Here we consider insights gained from a different approach, one that considers the multiple computational demands of the decision-making system in the context of neural mechanisms specialized to accomplish some of that system's more basic functions. The use of explicit computational models has led to (a) identification of core trade-offs imposed by a single-system solution to cognitive problems that are solved by having multiple neural systems, and (b) novel predictions that can be tested empirically and that serve to further refine the models.     

Integrating Contextual Issues in Ethical Decision Making

Many issues in ethics arise in relation to the contexts in which psychologists work. However, most ethical decision-making models reproduce the way in which psychologists tend to approach ethics by focusing on ethical dilemmas and proposing a step-by-step response to deal with them. Although these models might be useful, their emphasis on reactive approaches and their lack of contextualization constitute significant limitations on their applicability. In this article, an approach to ethical decision making that highlights the importance of the context in developing proactive strategies to solve ethical issues is proposed. This approach is further explained through its application to medical and rural settings. The implications of these suggestions to the training in ethics are finally discussed.     

决策中的延迟选择行为

延迟选择(choice deferral)指个体在应该作出选择的时候却决定不作选择,包括推迟选择(如选择延迟选项)或拒绝在可选项中选择一个选项。本文首先探讨了影响延迟选择行为的认知因素和情绪因素;随后讨论了当在决策情景中引入延迟选项时,延迟选项对决策者随后情绪体验和决策行为的影响;最后对未来研究进行了展望。     

Decision Neuroscience: New Directions in Studies of Judgment and Decision Making

ABSTRACT— Investigations of decision making have historically been undertaken by different disciplines, each using different techniques and assumptions, and few unifying efforts have been made. Economists have focused on precise mathematical models of normative decision making, psychologists have examined how decisions are actually made based on cognitive constraints, and neuroscientists have concentrated on the detailed operation of neural systems in simple choices. In recent years, however, researchers in these separate fields have joined forces in an attempt to better specify the foundations of decision making. This interdisciplinary effort has begun to use decision theory to guide the search for the neural bases of reward value and predictability. Concurrently, these formal models are beginning to incorporate processes such as social reward and emotion. The combination of these diverse theoretical approaches and methodologies is already yielding significant progress in the construction of more comprehensive decision-making models.

Beyond the Obvious: Chronic Vividness of Imagery and the Use of Information in Decision Making

The authors investigate two competing hypotheses about how chronic vividness of imagery interacts with the vividness and salience of information in decision making. Results from four studies, covering a variety of decision domains, indicate that chronic imagery vividness rarely amplifies the effects of vivid and salient information. Imagery vividness may, in fact, attenuate the effects of vivid and salient information. This is because, relative to nonvivid imagers, vivid imagers rely less on information that appears obvious and rely more on information that seems less obvious. This tendency is so robust that vividness of imagery may amplify the effects of vivid information only when this information is the only information available in the decision field. The findings seem to reflect vivid imagers' tendency to totally immerse themselves in a decision problem and scrutinize the available information creatively.

The Theory and Practice of Foreign Policy Decision Making

Central to Alex George's work was a concern with the psychology of presidential decision making. Our analysis focuses on George's work at the intersection of leadership psychology and the psychology of judgment in the making of consequential foreign policy decisions, specifically those dealing with issues of war and peace. We begin with a review of the fundamental dilemmas of political decision making, focusing on the various factors that present challenges to leaders seeking to make high-quality decisions. We then move to an analysis of the nature of judgment and the ways in which it both shapes and is shaped by cognitive dynamics and conclude by examining a number of steps designed to help leaders avoid the most damaging blind spots of their own psychologies and cognitive biases.
