How mask gap impacts discrimination and anxiety during COVID-19: A study on overseas Chinese during the first outbreak in 2020

The outbreak of the COVID-19 pandemic brought unrelenting waves of xenophobia against people representing vulnerable populations, among them those identified as Asians or more specifically as Chinese. Although previous studies have found that some discriminatory actions against overseas Chinese were closely related to mask use during the pandemic, there is not much evidence that explicates what might be the social-cultural triggers or impact of self-other mask discrepancy. The current study aims to examine how a mask use gap impacts perceived discrimination and anxiety during the first outbreak of COVID-19, and how perceived discrimination mediates the mask gap–anxiety relationship. This was operationalized by developing a new “mask gap” variable to capture the incongruent mask use norms between Chines and others around them in the host country. Data were collected from a cross-sectional sample of Chinese (n = 745) residing in 21 countries from March to May 2020 during the first wave of the pandemic. Results showed the newly explicated “mask gap” variable was associated with a higher level of anxiety. In addition, perceived discrimination mediated the mask gap-anxiety relationship. These findings advance both theoretical and practical understandings of how incongruent social norms impact discrimination and mental health during health threat events like the COVID-19 pandemic. The results also suggest important implications for both societal responses and the mental health of sojourners or immigrants during pandemics.

Are action planning and physical activity mediators of the intention-habit relationship?

ObjectivesPhysical activity is associated with many health benefits that are important for older adults. These health benefits can only be obtained and preserved when physical activity is maintained over a long period of time. Habit formation has been proposed as a way to ensure long-term maintenance of physical activity. Intention, action planning, and physical activity are suggested to be determinants of physical activity habits. However, how they determine physical activity habits in older adults is largely unknown. This study examined whether the relationship between intention and habit is mediated by action planning and/or physical activity.DesignA four-wave prospective design was used.MethodsTwo independent studies were conducted in 469 (Study 1; M_age = 63.07, SD_age = 7.61) and 322 (Study 2; M_age = 64.31, SD_age = 9.39) older adults. Study 2 was conducted with the aim of replicating findings of Study 1. In both studies the older adults completed questionnaires on intention, physical activity, and habit at baseline, action planning at three months, physical activity at six months, and habit at twelve months.ResultsStructural equation modeling analyses showed significant intention-physical activity-habit paths, nonsignificant intention-action planning-habit paths, and nonsignificant intention-action planning-physical activity-habit paths in both studies.ConclusionsThe relationship between physical activity habit and intention was mediated by physical activity. Intention was neither associated with habit via action planning as a single mediator, nor via action planning and physical activity as sequential mediators. Possible conditions under which intention-action planning-habit paths and intention-action planning-physical activity-habit paths exist are discussed.     

Error is proportional to distance measured by honeybees: Weber’s law in the odometer

Honeybees were trained to fly a specific distance, the same over trials, down a tunnel for a reward. After training, they were tested occasionally with the reward absent. On tests, bees fly to or just past the expected place of reward, then turn around and fly back. After some distance, they turn back again, and may continue turning back and forth a number of times. Past research has shown that distance estimation in this task is based on the retinal flow of visual texture on the walls of the tunnel. Here we measured the errors in distance estimation as a function of training distance. Errors were measured as the standard deviation across trials of the positions of the first two turns (Turn1 and Turn2), and of the Middle (average of Turn1 and Turn2) and Spread (difference between Turn1 and Turn2). All errors were proportional to the training distance, thus obeying Weber’s law. Models of possible mechanisms underlying this phenomenon are discussed. The mean Spread matches the errors in Turn1 and Middle, suggesting that the bee chooses the spread of its search to match the expected odometric error.

达者何以兼济天下：高阶层再分配偏向的心理机制及谦卑的作用

一些欧美研究发现高阶层者与低阶层者相比再分配偏向更低, 但是这一结论尚缺少跨文化一致性的证据, 而且对于这一现象的心理机制和干预策略的探讨也相对不足。基于此, 本研究通过3个子研究分别来关注我国民众再分配偏向的阶层差异及其心理机制, 并探讨可能的干预策略。结果发现：(1)与西方社会的情形相似, 在中国社会高阶层者的再分配偏向也显著低于低阶层者; (2)社会阶层对再分配偏向的影响, 部分是通过贫富差距归因倾向起作用的：与低阶层者相比, 高阶层者更倾向于将贫富差距归因于能力、努力、志向或抱负等个体内部因素, 进而再分配偏向更低; (3)通过启动高阶层者谦卑的心态, 能够降低其贫富差距内归因倾向, 进而提升其再分配偏向。此结果验证了社会阶层不平等维持模型的重要观点, 同时也为推动社会再分配、促进发展成果共享等提供了一定的社会治理启示。     

A systematic review of definitions of motor vehicle headways in driver behaviour and performance studies

Headway is a safety measure commonly used to investigate driving behaviour and driver performance. Its purpose is to reflect the following distance or time between a leading and following vehicle in traffic. It is therefore associated with drivers’ response time, such as in braking or swerving, during safety critical events. In the literature, distance and time headway are defined in different ways, despite standard definitions in the traffic engineering literature, which prompted this systematic review of headway definitions across a range of study designs, in order to recommend approaches to improve the accuracy and reproducibility of headway definitions used in road safety contexts. PRISMA guidelines were followed to search four databases (EMBASE, COMPENDEX, SCOPUS and MEDLINE) for studies that reported on headways or discussed methodological approaches. The search and filtering of abstracts identified 110 articles for a qualitative synthesis. Four broad approaches to measuring headways were detected: studies using simulation, roadside external features, on-road features, and on-vehicle features. Studies were coded as to whether they included written explanation, mathematical statements, or pictorial depictions of headway. Only 49.6% of studies contextualised headway sufficiently for reproducibility. Reproducibility is crucial for accurate interpretation of research findings and comparisons across studies. It is recommended that headway definitions should a) exclude vehicle or parts of vehicle lengths, b) include reference points (e.g., bumper/axle/rear), c) have a consistent terminology, and d) include the accuracy of headway measuring devices to report the precision of a study’s findings.     

判断与决策中的投射偏差

投射偏差是指个体常常会高估未来偏好与当前偏好的一致性, 从而把当前偏好投射到未来的心理倾向性。本文从情感–认知加工、时间修正和心理模拟等视角对投射偏差的心理机制进行了解释, 并概括出投射偏差的内源性(含内脏感觉、情绪状态和需要)和外源性(含事件相关信息、天气状况和选择情境)影响因素, 还总结归纳出投射偏差的三种应对策略, 最后指出了投射偏差在未来研究的方向。     

基于三参照点理论的薪酬差距与离职决策的分析

离职是组织管理研究中一个重要的课题, 但鲜有研究将其纳入风险决策的框架中。本文运用行为决策的研究方法, 将离职作为一种风险选择, 运用三参照点理论探讨个体薪酬差距与离职决策之间的关系。我们的理论分析和初步的预研究发现：(1)个体薪酬现状与底线的差距负向预测离职决策, 薪酬目标与现状的差距正向预测离职决策; (2)进一步推导出薪酬差距与离职决策间存在双拐点的非线性函数关系; (3)同行现状收入作为横向参照系, 在薪酬差距与离职决策两者之间起锚定作用; (4)组织中薪酬分布的差距大小作为纵向参照系, 在薪酬差距与离职决策两者之间起调节作用。本研究将离职作为一种风险决策进行研究, 不仅对于离职理论与决策理论的发展有一定意义, 而且为人力资源管理实践提供了指导与启示。     

More Than A Feeling: The Communicative Function of Regret

Rüdiger Bittner argues that regret is not useful and so it is always unreasonable to feel and express it. In this paper, I argue that regret is often reasonable because regret has a communicative function: it communicates where we stand with respect to things we have done and outcomes that we have caused. So, I not only argue that Bittner’s argument is unsuccessful, I also shed light on the nature and purpose of regret.
