眼动轨迹匹配法是近年来新兴的一种眼动数据分析方法, 该方法包括注视数据的预处理、兴趣区划分和编码、形成眼动轨迹字符串、计算相似性得分四个步骤。研究者采用眼动轨迹匹配法对决策过程理论及其影响因素进行的探索性研究, 证实了眼动轨迹匹配法在决策领域的可行性、精确性和高价值性。未来的研究应进一步利用眼动轨迹匹配法加强对各种决策理论及其影响因素的研究, 以揭示决策的认知过程, 构建更加完善的决策理论模型。  相似文献

结合眼动注视的漂移扩散模型可很好描述个体的决策行为,但尚存在两个问题未得到解决:注视与决策的因果关系以及决策过程中累积证据的权重问题。本研究采用基于注视的操纵范式考察了基于价值的决策中注视与决策的关系,发现操纵被试对选项的注视时间可影响其选择,注视操纵主要影响决策后期时程,且模型参数估计结果更支持近因模型。研究结果支持了漂移扩散模型的近因假设,为今后的模型发展指明了新方向。  相似文献

在跨期决策研究领域,虽然基于维度的跨期模型得到了一些源自结果检验和过程检验的证据支持,但此类模型所假设的维度间差异比较的心理过程尚缺乏直接的过程证据。本研究通过两个眼动实验,系统考察了相关眼动指标对维度差异偏好的预测效应。结果发现,根据基于维度的权衡模型可有效拟合出个体在跨期决策中的维度差异偏好,并且反应时、眼跳注视熵和静态注视熵等指标均与维度差异偏好负相关,而基于维度的注意分配与维度差异判断正相关。这些研究发现支持了本研究所提出的跨期眼动模型的相关假设,证实了维度差异偏好与跨期决策的认知加工过程之间的联系,为基于维度的跨期模型提供了更直接的过程证据,并为今后跨期决策的眼动模型发展指明了新方向。  相似文献

风险决策和跨期决策与人类生存发展密切相关, 且两类决策在理论发展、行为效应及神经基础等方面具有相似性。为检验二者是否具有共同过程机制, 本研究以风险决策中的确定效应和跨期决策中的即刻效应为例, 采用眼动追踪技术比较了它们的局部、整体过程及模型拟合。辅以贝叶斯因子分析实验数据表明:二者的主要过程特征均相似, 且更符合非折扣模型假设; 二者在加工复杂程度等少数特征上有所不同; 确定和即刻信息在加工方向等特征上存在特异性。这表明二者可能具有共同的核心决策规则:两类决策更可能遵循非折扣模型预期的简捷、启发式规则, 而不是折扣模型所假设的补偿性、基于选项规则。本研究为建立两类决策的共同解释框架做出了有益尝试, 并为决策比较研究方法提供新的方向。  相似文献

在过去50年的决策研究中,随着对核心问题的深入探索和信息技术的发展,决策过程信息得到了越来越多的重视.过程研究技术主要包括鼠标实验室技术、眼动技术及新提出的决策移窗技术.鼠标实验室技术和眼动技术已被用于解决多种决策问题.决策移窗技术结合了前两种技术的优势,其适用范围需在日后研究中进行更多探索.在未来的研究中,多种技术的结合使用将有助于回避单一技术的缺陷,分离研究方法对于被试行为的影响,提高研究效度.  相似文献

采用眼动追踪技术探究了在一般决策过程中决策者的眼动规律和结果呈现对决策的影响。结果表明,在决策过程中,收益信息比概率信息更受决策者关注;决策者的注视点在选项内转换多于在选项间转换;决策前的眼动指标对最终的选择有很强的预测作用,决策者会在最终选择的选项上投入更多认知资源;结果的呈现使风险偏好型决策者在决策获益后趋于保守,更关注低风险选项;而风险回避型决策者在决策获益后会变得敢于冒险。  相似文献

采用眼动研究法探究注视对决策偏好的反映及影响。实验1让被试完成特征判断迫选任务,并记录被试的注视行为。注视可能性分析发现,被试在决策前逐渐将注视转向要选择的选项。实验2采用注视追随反应提示范式研究注视对决策偏好的影响,结果发现被试的选择在缺乏客观决策信息时系统地偏向了随机确定的目标选项。实验结果表明,注视能反映决策偏好的形成过程,也能影响决策偏好。研究结果支持决策信息处理的双阶段理论。  相似文献

眼动范式是场景知觉研究的重要方法之一,可以通过对场景知觉过程中眼动变化的实时记录,真实地反映场景信息加工的内在心理机制;然而,人们的心理活动是极其复杂的,与之相应的眼动指标也具有多样性和复杂性。对眼动指标的分析,有不同的分析维度,比如整体和局部、时间和空间等。本文回顾了已有的眼动指标分类,并尝试从注视和眼跳的视角对场景知觉过程中的眼动指标进行分类。在此基础上,从界定标准、心理学意义、研究应用等方面对相应的眼动指标进行分析和介绍,最后提出了眼动指标分析和应用可能存在的问题,以及未来研究可能拓展的领域。  相似文献

“时间”是跨期决策的“必需品”, 人们感知到的延迟时间决定跨期决策的结果。近年来, 研究者发现“时间长度感知”、“时间资源感知”和“时间框架感知”是时间感知作用于跨期决策的主要方式。时间感知的神经作用机制包含微观层面和宏观层面两种。“对数/指数时间折扣模型”、“感知时间基础模型”及“多模态漂移扩散模型”解释了时间感知的作用方式。然而, 现有理论模型还存在诸多局限, 主要包括“长短时距预测偏差”和“实际决策与预期决策偏差”两个方面。因此, 深入探讨时间感知影响跨期决策的基本方式, 分析现有理论模型的局限性并提出整合的机制框架具有十分重要的意义。未来研究亟需进一步整合时间感知的理论模型, 开展脑机制与应用方面的研究, 从深层揭露时间感知的作用本质, 帮助个人与社会更理性地决策。  相似文献

The aim of this study was to examine whether dispositional optimism and induced optimism are associated with an attentional bias for positive stimuli. Fifty-six healthy participants performed an eye-tracking task twice, while their gazing time at faces displaying joy, anger, pain, or a neutral expression was measured. Participants scoring high on dispositional optimism tended to gaze longer at joy faces during the first face-presentation trial compared to participants scoring lower on optimism, and this correlation became significant during the second face-presentation trial. In between the two presentations, participants received either an optimism manipulation or a control manipulation. There was no effect of type of manipulation on gazing behavior but post hoc analyses demonstrated that participants showing an increase in state optimism displayed a significant decrease in gaze duration for anger faces and a nearly significant increase in gaze duration for joy faces.  相似文献

The aim of the current study was to investigate the effects of reappraisal, acceptance, and rumination for regulating anger and sadness on decision-making. Participants (N = 165) were asked to recall two autobiographical events in which they felt intense anger and sadness, respectively. Participants were then instructed to reappraise, accept, ruminate, or not use any strategies to regulate their feelings of anger and sadness. Following this manipulation, risk aversion, and decision-making strategies were measured using a computer-based measure of risk-taking and a simulated real-life decision-making task. Participants who were instructed to reappraise their emotions showed the least anger and sadness, the most adaptive decision-making strategies, but the least risk aversion as compared to the participants in the other conditions. These findings suggest that emotion regulation strategies of negative affective states have an immediate effect on decision-making and risk-taking behaviors.  相似文献

不平等问题是全球社会和经济发展需要应对的首要挑战, 也是实现全球可持续发展目标的核心障碍。人工智能(artificial intelligence, AI)为缓解不平等、促进社会公平提供了新的途径。然而, 新近研究发现, 即使客观上AI决策具有公平性和准确性, 个体仍可能对AI决策的公平感知较低。因此, 近年来越来越多的研究开始关注AI决策公平感知的影响因素。然而, 目前研究较为分散, 呈现出研究范式不统一、理论不清晰和机制未厘清等特征。这既不利于跨学科的研究对话, 也不利于研究者和实践者对AI决策公平感知形成系统性理解。基于此, 通过系统的梳理, 现有研究可以划分为两类: (1) AI单一决策的公平感知研究, 主要聚焦于AI特征和个体特征如何影响个体对AI决策的公平感知; (2) AI-人类二元决策的公平感知研究, 主要聚焦于对比个体对AI决策与人类决策公平感知的差异。在上述梳理基础上, 未来研究可以进一步探索AI决策公平感知的情绪影响机制等方向。  相似文献

Previous research on individual differences in career decision-making processes has often focused on classifying individuals into a few types of decision-making styles based on the most dominant trait or characteristic of their approach to the decision process (e.g., rational, intuitive, dependent; Harren, 1979). In this research, an alternative approach, which offers a multidimensional profile characterization of individuals’ career decision-making processes based on a simultaneous consideration of 11 dimensions, is presented. Thus, the proposed model refers to career decision-making profiles rather than career decision-making styles. The model, which emerged from a systematic analysis of previous research, was refined on the basis of preliminary empirical tests (five samples, N = 2764) using the Career Decision-Making Profile (CDMP) questionnaire. Study 1 reports the psychometric properties and the results of an exploratory factor analysis of the CDMP questionnaire, in a sample of young adults deliberating their career decisions (N = 285). Study 2 presents the results of a confirmatory factor analysis, based on Israeli (N = 431) and US (N = 208) samples of young adults. The results of both studies supported the hypothesized 11 dimensions. The implications for future research and for counseling are discussed.  相似文献

为考察道德情绪对道德决策的影响,研究以123名13岁和16岁的青少年为被试,采用2(年龄:13岁、16岁)×2(情境类型:亲社会、反社会)×2(情绪预期:道德定向、自利定向)的混合实验设计,考察了在不同的情境中和不同定向的情绪预期下青少年的道德决策情况。结果表明,年龄和情境类型的交互效应显著,反社会情境中16岁青少年比13岁青少年更倾向于判断自己会做出道德行为,亲社会情境中两个年龄组的道德决策判断无显著差异。情境类型和情绪预期的交互作用也显著。反社会情境中,青少年在自利定向情绪预期下判断自己会做出道德行为的可能性显著大于道德定向情绪预期;亲社会情境中,两种预期下青少年的道德决策判断不存在显著差异。结果说明,道德情绪会影响青少年的道德决策,在不同的情境中对道德决策的影响不同。  相似文献

In two studies, we investigate the effects of individuals’ power motivation on decision-making. We distinguish between two types of power motivation [McClelland, D. C. (1970). The two faces of power. Journal of International Affairs, 24, 29–47; Winter, D. G. (1973). The power motive. New York: The Free Press] and demonstrate that both types of power motivation facilitate influential decision-making but that each type plays a different role in different contexts. In a conflict context (Study 1), individuals’ personalized (self-serving) power motivation was associated with antisocial decisions, and in a healthcare context (Study 2), individuals socialized (other-serving) power motivation was associated with prosocial decisions. Furthermore, the type of power motivation elicited in each context was associated with less perceived need to deliberate over the relevant policy decision. In separating out the independent effects of each type of power motivation, we are able to explain more variance in decision-making behavior across various contexts than in models using aggregate power motivation (personalized plus socialized).  相似文献

This paper explores the process of ethical decision-making in counselling research and asks the question: after following ethical guidelines, reviewing ethical principles and consulting codes of practice, to what extent is our decision-making based on intuitive thinking? The paper begins by examining Kitchener's model of ethical justification and the ethical principles upon which it rests. Bond's approach to ethical problem-solving is also considered. The second part of the paper explores the sequential decision-making process suggested by Gellatt, upon which both the Kitchener and Bond models seem to rest, and compares this with Gellatt's later revision of his model. The process by which we arrive at an ethical decision is then explored in relation to these. The final part of the paper argues that we reach ethical decisions through intuition, informed by ethical principles, codes of practice and reference to the laws of society. In order to safeguard the well-being of our clients and/or research participants, we need to be aware of this and offer up our decision-making process to the scrutiny of peers and the public at large. Although much of the paper explores this process at a general level, research undertaken into children's perception of stress will be used as an example.  相似文献
