基于参数表征的数量空间关系加工

空间关系的理解是概念表征向知觉表征的转化, 而空间关系的表达则是知觉表征向概念表征的转化。两种表征的转化以参照系为中介。视觉数量空间关系加工属于知觉表征向概念表征转化的空间关系表达过程。本研究通过控制方向、朝向及距离在启动与探测中的匹配关系, 采用三个实验探讨了数量空间关系加工中参照系各参数的表征及其相互作用。结果发现：(1) 数量空间关系加工中存在方向表征, 一定任务情境下存在朝向表征。(2) 距离匹配的促进效果只在启动刺激和探测刺激的方位关系处于参照系同轴时发生。这些结果进而说明, 数量空间关系加工中内隐地包含类别空间关系表征, 一定任务情境下, 可能存在垂直/水平的类别空间关系表征; 数量空间关系加工中的距离是联系于参照系轴的表征。     

Indifference sets of reference points in multi‐objective integer linear programming

Reference point approaches for multi‐objective problems rely on the definition of an achievement scalarizing function that projects reference points onto the non‐dominated solution set. In this paper, we investigate the behaviour of reference points using a Tchebycheff metric‐based scalarizing function in multi‐objective pure integer linear programming (MOILP). Since the non‐dominated solutions are discrete in MOILP, there are multiple reference points that lead to the same solution, i.e. there are indifference sets on the reference point space. We investigate some properties of the reference points in MOILP and also the graphical representation of indifference sets for tri‐objective problems. We further investigate properties of the reference points when additional limitations on the objective function values are introduced. Copyright © 2001 John Wiley & Sons, Ltd.     

地面参照框架形成的连续表面整合加工假说

地面参照框架是空间知觉的重要基础, 连续表面整合加工(SSIP)假说首次对其形成过程做出了推测, 将这一科学问题的研究向纵深推进, 开辟了一个新的研究领域。SSIP假说的核心观点及其相关证据包括地面的表征原理、整合条件和表征结果三个方面, 得到了大量研究的支持。未来研究需结合基于过程检验的技术手段, 直接探查地面参照框架的形成机制, 关注高级认知过程的作用, 并可考虑其在国防上的应用。     

The Methodological Implications of Reference Magnetism on Moral Twin Earth

The Moral Twin Earth challenge to ethical naturalism threatens to undermine an otherwise promising metaethical view by showing that typical, naturalist-friendly theories of reference determination predict diverging reference in Twin Earth scenarios, making it difficult to account for substantive moral disagreement. Several theorists have recently invoked David Lewis’s doctrine of reference magnetism as a solution, claiming that a highly elite moral property—a moral “joint in nature”—could secure shared reference between ourselves and our twins on Twin Earth, despite our diverging usages of moral terms. This paper argues that this move has significant methodological implications: namely, it entails that a certain sort of simplicity is truth-conducive. Consequently, when applied to moral theories, this gives certain views, specifically monist ones like utilitarianism and contractualism, an advantage over their more complicated rivals, forms of pluralism and particularism. Thus, ethical naturalists cannot invoke reference magnetism without a substantial impact on first-order theorizing.     

The Influence of Institutional Salience on Political Attitudes and Activism among Catholic Priests in the United States

What motivates clergy political attitudes and behavior? We investigate this using a questions‐as‐treatment randomized experiment focusing on Roman Catholic priests in the United States. Our results suggest substantial utility in using a question frame referencing the distinct institutional expectations that clergy regularly confront. Specifically, when randomly primed to consider the expectations of institutional reference groups, clergy exhibit significantly higher levels of conservatism and report higher levels of political engagement, which is in line with their church's institutional preferences more generally. Our findings underscore the need for experimental methodology to make increased inroads into understanding political outcomes in religious contexts.     

Compared to what? The effects of a frame of reference on older adults’ subjective memory

It is often unclear what comparisons older adults make when evaluating their own memory. If thinking about their memory relative to others, they may assess their own abilities differently than if comparing it to their past capabilities. To test the effect of reference frames on memory assessments and memory performance, we randomly assigned 120 older adults to one of three conditions in which we manipulated frames of reference (control, past-self comparison, or other adults comparison) on a memory self-efficacy questionnaire. Participants also completed general and specific memory predictions and an objective memory test. Participants in the past-self condition reported significantly lower global memory self-efficacy compared with the other adults and control conditions. No condition differences emerged for memory predictions, objective memory, or the likelihood of over- or underpredicting memory performance. These findings suggest that reference frames impact global memory self-efficacy, but do not influence the accuracy of subjective memory judgments.     

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。     

正负参照点下性别和损益情景对大学生延迟折扣的影响

大量研究表明,延迟折扣受到个体特质性和状态性因素的影响。本研究通过两个实验分别探究正参照点(实验1)和负参照点(实验2)下,特质性因素性别和状态性因素损益情景对大学生个体延迟折扣的影响。实验1研究发现,在正性参照点下,无论男女,收益情景的主观远期价值远高于损失情景。实验2研究发现,在负性参照点下,男女在损益情景的主观远期价值不同;与男性相比,女性的主观远期价值在损失情景中更高,而在收益情景中则无显著差异。本研究结果表明,在不同的参照点下,男女在损益情景中表现了不同的延迟折扣倾向;与男性相比,女性在负性参照点面对损失情景跨期选择时,更愿意选择延迟赔偿。     

Truth-Sensitivity and Folk Epistemology

Several studies have found a robust effect of truth on epistemic evaluation of belief, decision, action and assertion. Thus, truth has a significant effect on normative participant evaluations. Some theorists take this truth effect to motivate factive epistemic norms of belief, action, assertion etc. In contrast, I argue that the truth effect is best understood as an epistemic instance of the familiar and ubiquitous phenomenon of outcome bias. I support this diagnosis from three interrelating perspectives: (1) by epistemological theorizing, (2) by considerations from cognitive psychology and (3) by methodological reflections on the relationship between folk epistemology and epistemological theorizing.
