道德直觉决策及其机制探析

道德直觉决策研究是从直觉思维角度探讨决策者在道德境遇下的决策。道德直觉决策是道德情境下的直觉反应, 其理论基础包括躯体标记假说、社会直觉模型、双加工理论、事件特征情感复合体系以及双系统理论; 道德直觉决策机制至少包括：无意识加工、情绪加工和直觉加工三个基本的心理加工过程, 与之对应的神经系统则至少存在三个可能的脑神经回路：无意识加工的道德脑区、情绪加工的道德脑区和直觉加工的道德脑区。研究主要从客观和主观两方面分析了道德直觉决策的一般性影响因素--文化、道德境遇、经验、情绪和道德直觉; 揭示了道德直觉决策的加工机制。未来研究应在加强理论建构的基础上, 通过更缜密细致的实验设计去探究决策过程中各因素的交互作用, 并明确道德脑区之间的联结。     

自我损耗降低决策理性:心理机制与边界条件

处于自我损耗状态时, 个体在意愿上偏好即时利益和目标, 并且会做出许多非理性决策行为。在梳理自我损耗对行为决策的影响基础上, 指出自我损耗降低决策理性的注意机制和执行机制:一方面, 损耗使个体注意力更容易为即时利益所捕获, 进而重视短期利益而忽视长远利益, 即降低个体关注未来的能力; 另一方面, 损耗导致个体缺少计划性和行为实施的执行力, 即降低个体坚守未来的能力。此外, 损耗对决策理性的影响存在个体和情境两个方面的重要边界。未来可结合眼动技术验证损耗降低决策理性的注意机制, 进一步探究潜在边界条件以及寻找助推理性决策的方法。     

风险决策的神经机制:基于啮齿类动物研究

风险决策是在不同选项的结果确定、并且结果出现的概率已知情况下的决策。啮齿类风险决策模型研究发现前额皮层-杏仁核-伏隔核神经环路联系是决定风险决策的选择倾向的关键。前额皮层中的眶额皮层和内侧前额皮层参与风险决策的策略形成和策略转换有关;而皮层下核团中的杏仁核、腹侧纹状体的伏隔核等结构参与策略保持、价值判断,影响决策偏向和行动强度;眶额皮层、伏隔核神经元和多巴胺神经元编码风险决策过程中的概率、风险等因素;此外,多巴胺等单胺类神经递质及受体在风险决策中有复杂的作用。     

青少年风险决策的发展认知神经机制

随着认知神经科学技术的发展, 青少年风险决策的发展认知神经机制成为了新近的一个热点课题。从双系统理论模型(社会情感神经网络系统、认知控制神经网络系统)出发, 对与青少年风险决策相关的大脑结构、功能的变化进行了阐述, 重点分析了新近的大脑功能连接、脑网络的研究; 阐述了青少年风险决策认知神经机制的主要理论模型：双系统模型和三角模型。未来研究还应加强对认知神经机制理论模型的检验、整合和创新, 从社会认知神经科学的角度深入研究社会参照系统(同伴关系、亚文化等)在青少年风险决策中的作用及机制, 以及从认知神经层面如何预防和干预青少年高风险行为。     

社会价值取向对自我-他人风险决策的影响及其机制

以往关于为自己和代他人决策的冒险行为研究结果不一致,这可能是因为以往的研究没有考虑决策情境和决策者人际特质等因素对于决策行为的影响。社会价值取向(social value orientation, SVO)是一种典型的人际特质,是个体在对自我和他人资源分配时所表现出的社会偏好,通常分为亲社会者和亲自我者。为探究SVO对自我-他人风险决策的影响及其机制,采用为自己和陌生人分别完成多轮混合赌博游戏的任务。结果发现亲自我比亲社会者代他人决策更冒险。用模型量化的损失厌恶和对潜在损失的敏感度部分中介了自我-他人风险决策差异,但只有对他人潜在损失的敏感度部分中介自我-他人决策的SVO效应。说明SVO会影响自我-他人风险决策,且该效应可以通过对他人利益的关心程度起作用,所以在自我-他人风险决策的研究中应将SVO这一决策者的人际特质因素考虑在内。     

不同任务框架下自我损耗对自我-他人风险决策的影响

为探究自我损耗对自我-他人风险决策的影响以及损耗后框架效应的变化,采用生态效度较高的气球模拟风险决策任务考察个体在自我损耗及不同任务框架下的风险偏好。结果发现：（1）自我-他人风险决策存在显著差异,为自己决策更冒险;自我损耗影响自我-他人风险决策,损耗后个体表现出更多的风险厌恶。（2）在自我-他人风险决策中,自我损耗增加了框架效应的敏感性。     

医疗风险决策的自我他人差异及其影响因素

从心理学的层面梳理医疗风险决策自我他人差异的表现及影响因素,狭义的医疗风险是患者在医疗服务的过程中因为医疗过失导致的损害等不安全事件,而广义的医疗风险包含了患者受到的伤害和整个医疗卫生体系受到的损失。在实际的医疗决策中,医生、家属和患者三方通常会做出不同的决策并且伴随着其立场的合理性,决策时也会受到决策框架和医疗决策模式等多方面的影响,可以采用解释水平理论、社会价值理论和双系统理论对不同决策主体之间的决策差异进行解释。未来可以从真实的医疗情境、个人特质、文化差异等方面进行深入研究。     

自我意识情绪:聚焦于自我的道德情绪研究

自我意识情绪是人们在社会交往中根据一定的价值标准评价自我或被他人评价时产生的情绪,也是个体根据道德自我认同标准,比较不同情境下的行为或行为倾向时产生的道德情绪。自我意识情绪以自我认知为基础,具有独特性。其中,内疚、羞耻、尴尬以及自豪和道德行为之间存在着千丝万缕的联系,并且有反馈、激发动机以及协调人际行为等道德功能。因此极有必要开展自我意识情绪的本土化研究,为建设和谐社会提供理论支持和实验根据。     

不同道德评价取向对企业道德决策的预测作用

本研究基于Hunt和Vitell（1986）所提出的市场营销领域的道德通用理论模型,随机选取129名MBA学生为被试,采用Reidenbach和Robin的多维道德量表和情景研究法,旨在考察个体在应对企业决策中的道德问题时,不同道德评价取向对道德决策（整体性道德判断和道德意图阶段）的预测作用。结果表明：1）与对道德判断的单项目测量相比,多维道德量表对道德意图具有高的预测效度;2）道德公平、功利主义和契约主义对整体道德判断具有显著的预测作用;3）道德公平和相对主义对自我和他人道德意图具有显著预测作用。     

当局者迷,旁观者清?自我-他人决策的理性差异及其机制

生活充满抉择,由于知识经验的局限,人们常需寻求他人建议,抑或直接请他人代己决策.诸多研究探讨了自我决策、向他人建议,以及代他人决策之间的差异.探究这种差异的动因之一在于考察何种条件下的决策更优或更“理性”.以往研究表明,自我决策或他人决策(向他人建议或代他人决策)均有可能更易违背理性决策原则,隐含着他人决策优于自我决策的“当局者迷,旁观者清”这一传统智慧有一定的边界条件.研究者一般从认知(建构水平理论)、情绪(类型和卷入度),以及动机(调节聚焦理论)三种视角对自我-他人决策差异进行解释.本文作者提出基于理由的决策(reason-based account)假设来解释自我-他人决策在理性程度上的差异.未来研究可从决策过程及脑机制上深入考察自我-他人决策差异及其机制.     

Mindfulness-based stress reduction effects on moral reasoning and decision making

Previous research has demonstrated that mindfulness-based stress reduction (MBSR) improves psychological functioning in multiple domains. However, to date, no studies have examined the effects of MBSR on moral reasoning and decision making. This single group design study examined the effect of MBSR on moral reasoning and ethical decision making, mindfulness, emotion, and well-being. Additionally, we investigated whether there was an association between the amount of meditation practice during MBSR and changes in moral reasoning and ethical decision making, emotions, mindfulness, and well-being. Results indicated that MBSR was associated with improvements in mindful attention, emotion and well-being. Further, amount of meditation practice was associated with greater improvement in mindful attention. Two-month follow-up results showed that, MBSR resulted in improvements in moral reasoning and ethical decision making, mindful attention, emotion, and well-being. This study provides preliminary evidence that MBSR may potentially facilitate moral reasoning and decision making in adults.     

基于道德认同理论的绿色消费心理机制

环境问题的加剧使得人们广泛关注如何保护人类赖以生存的生态环境。消费者在环保事业中扮演着举足轻重的角色。虽然,国内外已有一些关于绿色消费的研究,但是,对绿色消费心理机制的探究还不够系统和深入。借助社会认知视角下的道德认同理论探讨影响消费者绿色消费的心理机制,主要包括三方面的内容:(1)探索道德认同与绿色消费的中间机制,以及这一中间机制发挥作用的边界条件;(2)考察调节道德认同与绿色消费关系的变量;(3)检验道德认同表征与道德认同内化对绿色消费影响有何差异。基于社会认知视角下道德认同理论探讨绿色消费心理机制不仅可以丰富和发展道德认同和绿色消费相关理论体系,而且为政府和企业如何引导消费者的绿色消费提供了切实可行的建议。     

Moral knowledge: some reflections on moral controversies, incompatible moral epistemologies, and the culture wars.

An authentic Christian bioethical account of abortion must take into consideration the conflicting epistemologies that separate Christian moral theology from secular moral philosophy. Moral epistemologies directed to the issue of abortion that fail to appreciate the orientation of morality to God will also fail adequately to appreciate the moral issues at stake. Christian accounts of the bioethics of abortion that reduce moral-theological considerations to moral-philosophical considerations will not only fail to appreciate fully the offense of abortion, but morally mislead. This article locates the bioethics of abortion within the theology of the Church of the first millennium, emphasizing that abortion was prohibited, whether or not one considered the embryo or fetus to be ensouled.     

A dual-process approach to health risk decision making: The prototype willingness model

Although dual-process models in cognitive, personality, and social psychology have stimulated a large body of research about analytic and heuristic modes of decision making, these models have seldom been applied to the study of adolescent risk behaviors. In addition, the developmental course of these two kinds of information processing, and their relation to the development of self-regulation are not well understood at this time. The current paper reviews what leading dual-process models have to say about the development of analytic and heuristic decision making, and their implications for adolescent risk behavior. In addition, it reviews research on the prototype willingness model of adolescent decision making—a dual-process model designed specifically to address non-intentional, but volitional adolescent risk behavior. It also discusses the implications of dual-process models for intervention research.     

Perceived social context and risk preference: A re-examination of framing effects in a life-death decision problem

This study examines the effects of perceived group context on subjects risk attitudes and their sensitivity to the framing of choice outcomes in a ‘life-death’ decision problem. It seeks to uncover the psychological mechanisms underlying decision-making biases by systematically manipulating the decision context in which the ‘life-death’ problem was described. The study revealed that subjects risk preferences varied as a function of the experimental manipulations. Previously observed reversals in preferences (framing effects) appeared in large-group contexts and disappeared in small-group and family contexts. When considering the fate of small groups, subjects unambiguously favored the probabilistic outcome, no matter how the ‘life-death’ decision problem was framed. The empirical data obtained from the present study suggest that human choice patterns are behaviorally distinguishable across large-group, small-group, and family social contexts.     

Principled moral sentiment and the flexibility of moral judgment and decision making

Three studies test eight hypotheses about (1) how judgment differs between people who ascribe greater vs. less moral relevance to choices, (2) how moral judgment is subject to task constraints that shift evaluative focus (to moral rules vs. to consequences), and (3) how differences in the propensity to rely on intuitive reactions affect judgment. In Study 1, judgments were affected by rated agreement with moral rules proscribing harm, whether the dilemma under consideration made moral rules versus consequences of choice salient, and by thinking styles (intuitive vs. deliberative). In Studies 2 and 3, participants evaluated policy decisions to knowingly do harm to a resource to mitigate greater harm or to merely allow the greater harm to happen. When evaluated in isolation, approval for decisions to harm was affected by endorsement of moral rules and by thinking style. When both choices were evaluated simultaneously, total harm -- but not the do/allow distinction -- influenced rated approval. These studies suggest that moral rules play an important, but context-sensitive role in moral cognition, and offer an account of when emotional reactions to perceived moral violations receive less weight than consideration of costs and benefits in moral judgment and decision making.     

认知资源投入对框架效应的影响的实验研究

框架效应是描述决策理论违背规范决策理论的经典"异像",它的产生被认为是"不理性"的表现。投入认知资源有望削弱框架效应。为验证这一假设,本研究以128名有管理经验的文科类专业企业员工为被试,通过两个创业风险决策情景的重复验证,研究得出了一致的结论,即认知需求、加工深度和与创业决策情境的内在相关影响框架效应。研究还发现,认知需求高的个体框架效应减弱,信息加工深度会加重这种效应。     

Effects of valence and framing in decision making II: Estimating subjective weighting1

Abstract: In comparison between choice options, judgments of “How much better is a preferred option?” and “How much worse is a less preferred option?” may differ in their magnitudes. Such discrepancies are called “valence effects.” Previously, Yamagishi and Miyamoto (1996) observed systematic positive valence effects (“Better” exceeding “Worse”) in the domain of gains and systematic negative valence effects (“Worse” exceeding “Better”) in the domain of losses. The current experiment used the directions of valence effects as a tool to assess the decision maker's interpretation of choice tasks under the “framing effect” ( Tversky & Kahneman, 1986 ). Preferences under the framing effect switch from certain options in the domain of gains to uncertain options in the domain of losses. This study examined whether preferences for certain options were associated with positive valence effects, whereas preferences for uncertain options were associated with negative valence effects. Moreover, conditions under which preference reversals under the framing manipulations ceased to occur were examined. The effects of valence showed that framing effects ceased to occur when decision makers maintained consistent task interpretations as pertaining to gains or to losses. Most importantly, the pattern of subjective weighting under the valence effects was consistent with previous explanation of valence effects ( Yamagishi & Miyamoto, 1996 ). Possibilities for extending the current findings to understanding related psychological phenomena are discussed.     

Developing Moral Decision-Making Competence: A Quasi-Experimental Intervention Study in the Swiss Armed Forces

Moral development has become an integral part in military training and the importance of moral judgment and behavior in military operations can hardly be overestimated. Many armed forces have integrated military ethics and moral decision-making interventions in their training programs. However, little is known about the effectiveness of these interventions. This study examined the effectiveness of a 1-week training program in moral decision making in the Swiss Armed Forces. The program was based on a strategy-based interactional moral dilemma approach. Results of this quasi-experimental intervention study showed significant improvements in content-related (moral and instrumental awareness, quality of moral information processing, development of compensatory actions) as well as process-related (situational analysis, development and evaluation of alternative solutions, justification of decision) aspects in moral decision making. Results of a follow-up test indicated positive long-term effects with regard to moral and instrumental awareness and process-related aspects. Findings are discussed, and consequences for leadership development programs and further research are explored.     

Toward a new conceptualization and operationalization of risk perception within the genetic counseling domain

The purpose of this paper is twofold. First, it provides an historical overview of studies of risk, risk perception, and decision making under risk within the genetic counseling domain. Second, it proposes an alternative conceptualization and operationalization for the study of risk perception. The conceptualization involves probability, adversity, incompleteness, and ambiguity. Prior studies of risk perception focus on the recurrence risk and operationalize risk perception by asking for interpretations of the magnitude of the probability of the outcome. Their focus is on the probability of a particular outcome. We formulate the problem in terms of a gamble and suggest that risk perception be operationalized in terms of the riskiness of the gamble. Our focus is on the riskiness of a decision option which entails two or more outcomes.
