参照依赖和损失规避对个体收入分配公平判断的影响

收入分配公平判断是人们对自己收入所得公平与否的主观评价。通过对参照点和收入金额的控制,探讨参照依赖和损失规避对收入分配公平判断的共同影响。结果发现,(1)民众的收入公平判断受参照点的影响,在有参照点的情景下比无参照点情景下更感觉不公平;(2)不同工资水平下,民众的公平判断具有显著差异,而且民众对低于平均工资的“受损”比高于平均工资同等金额的“受益”赋予的公平感的权重更大,即存在得失感受的不对称;(3)不同的工资参照点、多得和少得的分配结果共同影响民众的公平判断,即损失规避在参照依赖对公平判断的影响中起调节作用。     

基于预期理论的参照依赖

参照依赖是指个体基于某一参照点对得失价值进行判断:参照点之上,个体感受为收益,反之即为损失.参照依赖现象广泛存在于生活中的各种领域.当前,对参照依赖心理机制的解释主要有预期理论、后悔理论和三阶段参照点理论.参照依赖的影响因素主要包括经验、情绪状态、文化、目标和认知对象的特点等.未来的研究应主要集中于参照依赖的产生根源,深入探讨参照依赖的神经机制,加强动态参照点、多重参照点以及群体中参照依赖现象的研究.     

得失程数的变化: 损失规避现象的新视点

损失规避是预期理论的核心部分之一, 指等量的损失和获得产生的心理效用并不相同, 前者大于后者。大量研究从生理、认知、情感等角度探讨损失规避的内在机制和规律, 以期认识、预测并控制损失规避导致的偏差。本研究假设损失规避与获得或损失的“程数”(route)有关, 以往研究发现了损失规避现象, 是由于其采用的“双程损失-单程获得”典型情境中, 损失程数多于获得程数。为检验该假设, 本研究设计了不同于传统范式的“获得和损失程数相等”的镜像情境、“单程损失－双程获得”及“三程获得”三种不同的得失情境。研究结果支持本假设: 当损失的程数等于或少于获得的程数时, 损失规避现象消失; 获得或损失的程数越多, 个体对其的心理感受强度趋于越高。建议未来研究进一步检验心理感受强度在程数和损失规避行为之间的中介作用。     

行为决策理论在能源节约管理中的应用

能源短缺是人类面临的重要课题,节约能源是人类需要采取的刻不容缓的行动。仅仅依赖金钱刺激很难解决能源浪费问题,而心理与行为科学可以发挥重要作用。本文梳理了应用行为决策的经典理论(如,安于现状偏差、决策双系统模型、参照点效应、框架效应和社会规范等)促进节能行为的研究成果,同时总结了诸如情绪、认知对象特点、信息呈现等影响个体节能行为的因素,最后从开展本土化研究、研究方式改进和拓展应对措施的角度对未来研究提出建议。希望本文能给心理学研究者一定的借鉴和启发,在节能管理领域做出更有价值的研究,以最终提高民众节能意识、增加民众节能行为。     

药物成瘾的易感性生物标记：从神经认知到分子遗传的证据

药物成瘾作为一种慢性复发性的脑疾病,具有从偶然性用药、规律性用药到强迫性用药的渐进式发展特征。研究提示,药物成瘾存在潜在的个体易感性机制,即在成瘾发生过程中不同个体接触药物后的成瘾风险并不相同,探索药物成瘾的神经生物标记是揭示成瘾易感性机制的重要途径。近十多年来,关于成瘾易感性标记的研究不断积聚。文章从神经认知、神经影像及脑电生理、分子遗传等层面梳理与药物成瘾生物标记有关的证据,试图在基因-大脑-心理-行为的理论框架下,对成瘾的发生发展机制进行综合阐释,期望为未来研究在探索药物成瘾的候选神经生物标记、寻找临床干预试验的精准靶点等方面提供更多理论参考。     

薪酬体系框架与考核方式对个人绩效薪酬选择的影响

研究从行为决策视角, 采用情景实验法探讨了薪酬体系框架与绩效考核方式对个人绩效薪酬选择的影响。结果表明：(1)个体根据实际收入水平低于/高于内心预期收入参照点将分别形成损失/收益性的预期收入框架, 在损失性收入框架下选择风险性绩效薪酬的几率更高; (2)底薪加提成的薪酬支付模式会让个体形成收益框架, 薪酬打包的支付模式会让个体形成损失框架, 个体在薪酬打包模式下选择绩效薪酬体系的几率更高; (3)与封闭式目标的考核体系相比, 企业采用开放式目标的绩效考核会抑制预期收入框架和薪酬支付框架对个人绩效薪酬选择的影响。     

损失规避的产生根源

损失规避是指由损失引发的负效用大于由等量收益引发的正效用的现象, 其产生根源能够从神经经济学和进化心理学两个方向进行解释。损失规避的脑机制分为两个系统：主观价值评价系统主要包括纹状体和前额皮层, 与主观价值的评估有关; 情绪唤醒系统主要包括杏仁核和脑岛, 与厌恶等消极情绪有关。在进化心理学的视角下, 通过回顾有关动物决策行为的研究来探索损失规避行为的进化历史, 并结合相关进化理论总结该行为产生的进化原因。未来可探索与行为损失规避相关的神经递质, 进一步研究损失规避的产生根源。     

行为经济学中的损失规避

损失规避是指,人们总是强烈倾向于规避损失：一定数额的损失所引起的心理感受,其强烈程度约相当于两倍数额的获益感受。这种强烈的心理与行为倾向广泛存在于风险与非风险领域,在该两个领域中损失规避的研究范式也不同。损失规避常见于经济和消费等领域,可用于解释行为决策中有悖于规范化理论的诸多现象,如禀赋效应、现状偏差、股权溢价之迷和赢者的诅咒等。然而,损失规避的机制研究还存在许多尚未解决的问题,如损失规避的本质以及适用条件。今后的研究不仅要注重认知角度和情感依恋,还要结合认知过程来研究损失规避的性质和内在机制,以期帮助人们认识、预测及干预由损失规避造成的经济损失和非理性决策。     

消费决策中的零：零价格效应和零比较效应

数字“0”由于自身所具有的特性(最小的自然数和不可作为被除数),当其与商品的价格维度和属性维度相结合时会对消费者的决策产生影响。已有研究表明商品的零价格和零属性会对消费决策产生影响,即零价格效应和零比较效应。情绪和社会规范是零价格效应产生的心理机制,参照依赖则是零比较效应产生的心理机制。商品价格、商品类型和消费者的心理因素是零价格效应的边界条件;而选项的数量是零比较效应的边界条件。未来的研究可以从不同商品类型、不同社会规范、“价格-损失”与“价格-质量”、注意等角度对零价格效应进行深入研究;也可以从结构匹配模型和齐当别模型的角度进一步探索零比较效应的“比较”机制;可以探讨价格是否能被视为商品的“坏属性”,进而讨论零价格效应和零比较效应二者之间的关系。     

心理疲劳与任务框架对风险决策的影响

本研究探讨心理疲劳对风险决策的影响, 以及任务框架对这一关系的调节作用。研究采用2 (疲劳, 非疲劳) × 2 (获益框架, 损失框架)被试间设计,实验组接受心理疲劳诱导后完成风险决策任务, 控制组直接完成风险决策任务。方差分析结果显示, 相对于非心理疲劳组, 心理疲劳状态下个体更倾向于风险规避, 且不受任务框架的影响。     

Extremes of self-esteem and narcissism and the experience and expression of anger and aggression

This study examined the level of self-esteem and narcissism as personality variables involved in the disposition to experience and express anger. Three hundred thirty-eight subjects were sampled across two higher education centres and one student teaching programme in the United Kingdom. It was reasoned that individuals with both high self-esteem and narcissism would report especially high tendencies to experience and express anger and aggression and that those with high self-esteem and low narcissism would report the lowest. These predictions were influenced by theories that emphasise the role of threats to high self-esteem in the production of aggression and violence. Results indicate that groups defined by their extreme scores on self-esteem and narcissism scales produced levels of anger expression in the predicted direction. The importance of considering extreme levels of self-esteem and narcissism (in conjunction with other factors) in an analysis of anger is discussed with reference to currently influential theories in the field.

Face aftereffects suggest interdependent processing of expression and sex and of expression and race

Bruce and Young (1986) proposed that functionally different aspects of faces (e.g., sex, identity, and expression) are processed independently. Although interdependent processing of identity and expression and of identity and sex have been demonstrated previously, evidence for interdependent processing of sex and expression is equivocal. Using a visual adaptation paradigm, we show that expression aftereffects can be simultaneously induced in different directions along anger–fear continua for male and female faces (Experiment 1) and for East Asian and Black African faces (Experiment 2). These findings for sex- and race-contingent expression aftereffects suggest that processing of expression is interdependent with processing of sex and race and are therefore problematic for models of face perception that have emphasized independent processing of functionally different aspects of faces. By contrast, our findings are consistent with models of face processing that propose that invariant physical aspects of faces and changeable social cues can be processed interdependently.     

理论思维、工程思维、评价思维的界定与联系——谈对缺血性脑血管病临床实践若干问题的思考

Recognition of faces of ingroup and outgroup children and adults

People are often more accurate in recognizing faces of ingroup members than in recognizing faces of outgroup members. Although own-group biases in face recognition are well established among adults, less attention has been given to such biases among children. This is surprising considering how often children give testimony in criminal and civil cases. In the current two studies, Euro-Canadian children attending public school and young adults enrolled in university-level classes were asked whether previously presented photographs of Euro-American and African American adults (Study 1) or photographs of Native Canadian, Euro-Canadian, and African American children (Study 2) were new or old. In both studies, own-group biases were found on measures of discrimination accuracy and response bias as well as on estimates of reaction time, confidence, and confidence-accuracy relations. Results of both studies were consistent with predictions derived from multidimensional face space theory of face recognition. Implications of the current studies for the validity of children's eyewitness testimony are also discussed.     

Values and Beliefs of Vegetarians and Omnivores

Abstract

Following the claim by some anthropologists and sociologists that 1 symbolic meaning of meat is a preference for hierarchical domination (C. J. Adams, 1990; N. Fiddes, 1989; D. D. Heisley, 1990; J. Twigg, 1983), the authors compared the values and beliefs of vegetarians and omnivores in 2 studies conducted in New Zealand. They compared the full range of vegetarians and omnivores on right-wing authoritarianism, social dominance orientation, human values, and consumption values. The participants tending toward omnivorism differed from those leaning toward veganism and vegetarianism in 2 principal ways: The omnivores (a) were more likely to endorse hierarchical domination and (b) placed less importance on emotional states. Accordingly, the acceptance or rejection of meat co-varied with the acceptance or rejection of the values associated with meat; that finding suggests that individuals consume meat and embrace its symbolism in ways consistent with their self-definitions.

Focus of attention and causal attributions of actors and observers

An experiment was conducted to test the hypothesis that actors' and observers' causal attributions are a function of their focus of attention. In the presence of observer-subjects, actor-subjects made a choice among several art works in a supposed decision-making study. The experiment was a 2 × 2 × 2 factorial design with the factors (1) source of attribution (actors, observers); (2) camera (actor videotaped, actor not videotaped); and (3) situational stability (stable, dynamic environment). As predicted by the focus of attention-causal attribution notion, it was found that actors attributed more causality to the situation than observers under normal circumstances, when the camera was not operative, but that videotaping the actor reversed the usual actor-observer pattern such that actors attributed less causality to the situation than did observers. Further, when the environment was stable, actors attributed more causality to the situation in the no camera condition than in the camera condition, while observers attributed less to the situation in the no camera conditions than in the camera conditions. Additionally, both actors and observers attributed more causality to the situation when the environment was dynamic than when the environment was stable.
