高中生数学能力实体观对数学学习投入的影响:学业自我效能感和消极学业情绪的中介作用

采用数学能力实体观量表、学业自我效能感量表、消极学业情绪量表（羞愧、厌倦）和数学学习投入量表,对1064名高中生进行调查。结果表明：数学能力实体观、学业自我效能感、羞愧、厌倦和数学学习投入之间均存在显著相关;学业自我效能感、厌倦在数学能力实体观和数学学习投入之间的中介作用均显著;且学业自我效能感-厌倦的链式中介作用也显著。这表明,高中生的数学能力实体观不仅可以直接预测数学学习投入,也可分别经由学业自我效能感、厌倦的中介作用、以及二者的链式中介作用影响数学学习投入。     

多维计算机化自适应测验中项目曝光控制选题策略的比较

在MCAT中考查四种项目选择指标在有无曝光控制条件下的选题表现。项目选择指标分别是:(1)贝叶斯的D优化方法(D-optimality)、后验期望Kullback-Leibler方法(KLP)、基于等权重复合分数的最小误差方差方法(the minimized error variance of the linear combination score with equal weight,V1)和基于最优权重复合分数的最小误差方差方法(the minimized error variance of the composite score with optimized weight,V2)。将针对认知诊断CAT项目曝光控制的的限制阈值方法(Restrictive Threshold,RT)和限制进度(Restrictive Progressive,RPG)方法、单维CAT中的最大优先指标方法(Maximum Priority Index,MPI)推广到MCAT。模拟研究表明:(1)KLP,D-优化和V1对领域分数估计准确,能力返真性比V2更好。(2)尽管V1和V2方法相比KLP和D-优化方法提高了题库利用率,但这四种选题指标都产生不均匀的项目曝光率分布。(2)三种曝光控制策略都极大地提高项目曝光均匀性,且不明显降低测量精度。(3)MPI与RPG方法在曝光控制方面表现类似,且比RT的方法表现更好。     

Buyers Versus Sellers: How They Differ in Their Responses to Framed Outcomes

Consumers’ reactions to a difference in price can depend on how it is framed. If buyers interpret paying $60 rather than $65 as getting a $5 discount, then they are likely to consider paying $60 to be a gain and paying $65 to be a nongain. Alternatively, if they interpret having to pay $65 rather than $60 as incurring a $5 penalty, then they may consider paying $60 to be a nonloss and paying $65 to be a loss. Similarly, sellers can also experience gains, nongains, nonlosses, and losses. This article suggests that buyers are prevention focused and consequently place a greater emphasis on loss‐related frames, whereas sellers are promotion focused and place a greater emphasis on gain‐related frames. Therefore, for equivalent positive outcomes, buyers feel better about nonlosses, but sellers feel better about gains. For equivalent negative outcomes, buyers feel worse about losses, but sellers feel worse about nongains. These effects, however, disappear when there is little motivation to process information about the monetary transaction.     

Quantifying visual field shape for improving accuracy of search performance prediction

The current study calculated a set of 16 shape indices of six subjects (4 men and 2 women, 21-28 years old) for easy and precise quantification of visual lobe shapes using Visual Lobe Measurement System (VILOMS) software. The indices can be used in mathematical models of visual search for better understanding of search behaviour and higher accuracy of search performance prediction. General patterns in the shape indices showed that visual lobes of the subjects were slightly irregular, with low sphericity, a moderately rough boundary, horizontally elongated and slightly asymmetric along both axes. Given the complex relationships among visual lobe area, lobe shape, and search strategy, it seems that a more detailed analysis than hitherto attempted will be necessary. Quantifying lobe shape with the 16 shape indexes is a useful step to performing such analysis.     

Individual differences in typing: pause length

An analysis of pause distribution for 12 subjects on a controlled copying task suggests that pause-based measures used to assess writing processes should reflect individual differences in typing.     

How does workplace ostracism hurt employee creativity? Thriving at work as a mediator and organization-based self-esteem as a moderator

Drawing on the socially embedded model of thriving and conservation of resources theory, we explore the negative effect of workplace ostracism on employee thriving. We model organization-based self-esteem (OBSE) as a moderator and extend our examination to the downstream implications of thriving for employee creativity. Using a scenario-based experiment (Study 1) with 387 working adults, we find that workplace ostracism is more likely to prevent workers with higher levels of OBSE from thriving at work. This finding is verified in Study 2, in which we use multiwave, multisource data collected from 207 employees and their supervisors to test the proposed model. The results further show that for employees with higher levels of OBSE, thriving at work is more likely to mediate the relationship between workplace ostracism and employee creativity. These findings provide important practical implications for fostering employee thriving and promoting creativity in the workplace by managing workplace ostracism.     

The effect of repeat purchase information in electronic word-of-mouth (eWOM) on purchase intention

Consumers commonly rely on electronic word-of-mouth (eWOM) to inform their purchase decisions. The purpose of this study is to investigate when and why repeat purchase information in eWOM influenced customers' purchase behavior, using the social learning theory as a framework. Three experiments were conducted to test the hypotheses. The results showed that repeat purchase information in eWOM positively affected consumers' purchase intention through perceived diagnosticity of eWOM and perceived value. Additionally, the effect varied from product type. For utilitarian products, the repeat purchase information in eWOM had a significant impact on consumers' perceived diagnosticity and purchase intention, while for hedonic products, the impact was not significant. The current study deepens the understanding of social learning theory in eWOM content by providing a novel look at repeat purchase information in eWOM. These findings offer important implications for both research and practical applications of eWOM, particularly in term of effectively utilizing repeat purchase information of eWOM.     

Cultural influence on COVID-19 cognitions and growth speed: The role of collectivism

Major challenges faced by humans often require large-scale cooperation for communal benefits. We examined what motivates such cooperation in the context of social distancing and mask wearing to reduce the transmission intensity of the coronavirus pandemic (COVID-19). We hypothesized that collectivism, a cultural variable characterizing the extent that individuals see themselves in relation to others, contributes to people's willingness to engage in these behaviors. Consistent with preregistered predictions, across three studies (n = 2864), including a U.S. nationally representative sample, collectivist orientation was positively associated with intentions, positive beliefs, norm perceptions, and policy support for the preventive behaviors. Further, at a country level, more collectivist countries showed lower growth rates in both COVID-19 confirmed cases and deaths. Together, these studies demonstrate the role of collectivism in reducing COVID-19 transmission, and highlight the value of considering culture in public health policies and communications.     

Exploring Individual Differences in the Experience of Anger in Sport Competition: The Importance of Cognitive,Emotional, and Motivational Variables

As anger is one of the most commonly experienced emotions in sport competition, this study aims to explore the individual differences in anger. A multisport sample of 269 athletes completed self-report measures of anger and several cognitive, motivational, and emotional variables. The results revealed significant differences in approach and avoidance motivation, anger rumination, thought suppression, antisocial behavior toward teammates and opponents, and self-control among athletes with different levels of anger. In addition, antisocial behavior toward opponents and teammates, anger rumination, challenge appraisals, and self-control predicted anger levels and significantly discriminated between athletes with low and high trait anger.
