团队权力分布差异对团队冲突的影响：程序公平和合法性的作用

近年来团队权力分布差异与团队冲突间关系受到了学界较大关注, 但相关研究结果仍存在分歧。通过对70个工作团队的调查, 探讨了团队权力分布差异对团队冲突(任务冲突、关系冲突)作用的边界条件。结果发现, 程序公平调节了两者间关系：当程序公平较高时, 团队权力分布差异与任务冲突、关系冲突负相关; 当程序公平较低时, 团队权力分布差异与任务冲突、关系冲突正相关。此外, 被中介的调节模型分析显示, 团队合法性感知中介了程序公平的上述调节作用。     

How Power States Influence the Persuasiveness of Top‐Dog versus Underdog Appeals

Although both top‐dog and underdog positioning appeals are widely used in marketing and advertising, little is known about which strategy is more effective in persuading consumers. By introducing a sense of power, a social variable that is inherently relevant to the nature of the top‐dog versus underdog classification, we propose that consumers' responses to these two appeals are influenced by their psychological experience of power. Specifically, low‐power consumers will respond to top‐dog appeals more favorably because associating with top dogs facilitates power restoration. In contrast, high‐power consumers will respond to underdog appeals more favorably because supporting underdogs facilitates power expression. In four experimental studies, we provide consistent support for our main predictions as well as the underlying processes. Studies 1 and 2 demonstrate the differential effect of consumers' power states on their attitudes toward top‐dog versus underdog appeals. Providing process evidence, Studies 3 and 4 identify boundary conditions under which the basic effect was eliminated. These findings contribute to the persuasion literature and power research and provide important implications for positioning strategy and advertisement development.     

Meta‐Analysis of Integrated Primary and Behavioral Health Care Interventions for Treating Substance Use Among Adults

This meta‐analysis detected low effects in reducing substance use (Hedges's g = –0.11) in favor of using integrated primary and behavioral health care (IPBH) compared with treatment‐as‐usual approaches for adult patients with substance use. The impact of IPBH was limited.     

权力对延迟选择的影响

本研究旨在考察权力对延迟选择的影响, 并探讨决策难度在其中的调节作用以及决策过程的中介作用。两个实验均先操纵个体的权力状态, 然后再请被试完成随后的延迟选择任务。结果发现, 决策难度可调节权力对延迟选择的影响, 当决策困难时, 高权力者具有更低的延迟倾向, 当决策容易时, 权力的影响消失。决策过程的加工变异性可中介权力对延迟选择的影响。结果表明, 低权力者比高权力者具有更高的延迟倾向(尤其当决策困难时), 不同权力水平者在决策过程上的差异或可部分解释此种现象。     

权力和地位对自利行为的影响及其机制

权力和地位对自利行为的影响不同。权力能够降低认知性观点采择水平,进而使个体更加关注自身利益;地位能够提升认知性观点采择水平,进而使个体推测他人思想与感受,考虑他人利益。然而,权力和地位通过认知性观点采择对自利行为的影响可能受到情境性质的调节。今后的研究应该对这些关系和解释进行验证,探索共情性关心的中介作用,以及权力和地位影响认知性观点采择的调节变量;探究权力和地位拥有者对群体内、外他人的自利行为差异;探讨权力和地位的交互作用对自利行为的影响。     

Divine Disaster Management: Cross and Resurrection as an Event of Creative Vulnerability

This article argues for a concept of a “responsive and creative divine vulnerability.” Such an understanding of the divine life relates differentiated conceptions of vulnerability, passion, and power. The article unfolds this specific understanding of divine vulnerability through a detailed analysis of the relation between the cross on the one hand and the resurrection of Christ in the power of the Spirit on the other hand.     

Addressing the “Replication Crisis”: Using Original Studies to Design Replication Studies with Appropriate Statistical Power

Psychology is undergoing a replication crisis. The discussion surrounding this crisis has centered on mistrust of previous findings. Researchers planning replication studies often use the original study sample effect size as the basis for sample size planning. However, this strategy ignores uncertainty and publication bias in estimated effect sizes, resulting in overly optimistic calculations. A psychologist who intends to obtain power of .80 in the replication study, and performs calculations accordingly, may have an actual power lower than .80. We performed simulations to reveal the magnitude of the difference between actual and intended power based on common sample size planning strategies and assessed the performance of methods that aim to correct for effect size uncertainty and/or bias. Our results imply that even if original studies reflect actual phenomena and were conducted in the absence of questionable research practices, popular approaches to designing replication studies may result in a low success rate, especially if the original study is underpowered. Methods correcting for bias and/or uncertainty generally had higher actual power, but were not a panacea for an underpowered original study. Thus, it becomes imperative that 1) original studies are adequately powered and 2) replication studies are designed with methods that are more likely to yield the intended level of power.     

Experimental Power for Indirect Effects in Group-randomized Studies with Group-level Mediators

Mediation analyses have provided a critical platform to assess the validity of theories of action across a wide range of disciplines. Despite widespread interest and development in these analyses, literature guiding the design of mediation studies has been largely unavailable. Like studies focused on the detection of a total or main effect, an important design consideration is the statistical power to detect indirect effects if they exist. Understanding the sensitivity to detect indirect effects is exceptionally important because it directly influences the scale of data collection and ultimately governs the types of evidence group-randomized studies can bring to bear on theories of action. However, unlike studies concerned with the detection of total effects, literature has not established power formulas for detecting multilevel indirect effects in group-randomized designs. In this study, we develop closed-form expressions to estimate the variance of and the power to detect indirect effects in group-randomized studies with a group-level mediator using two-level linear models (i.e., 2-2-1 mediation). The results suggest that when carefully planned, group-randomized designs may frequently be well positioned to detect mediation effects with typical sample sizes. The resulting power formulas are implemented in the R package PowerUpR and the PowerUp!-Mediator software (causalevaluation.org).     

权力感对风险决策框架效应的影响

框架效应是指由于对事物描述方式的改变而引起决策者偏好反转的现象。以权力的接近-抑制理论以及模糊痕迹理论为基础,研究探索了权力感对风险决策框架效应的影响及其发生机制。实验一通过回忆法对170名学生被试进行权力操纵,综合运用四种类型的决策情境,研究考察了权力感与框架效应的关系。结果发现,高权力组被试的框架效应显著,低权力组被试者的框架效应不显著。实验二探讨权力感与框架效应的内在机制。结果发现,信息加工深度中介权力感与框架效应之间的关系     

Maintaining Men's Dominance: Negotiating Identity and Power When She Earns More

This article examines the power dynamics in marriages where wives earn substantially more than their husbands based on in-depth interviews with husbands and wives in 30 couples. The results demonstrate how normative gender expectations constrain interactions between spouses and how spouses in these unconventional marriages struggle to construct appropriate gender identities that are more or less consistent with the conventional expectations that men should be breadwinners and women should be homemakers. These data represent an important counterpoint to the growing body of quantitative work that demonstrates that a woman's power diminishes as her income exceeds her husband's by illuminating how men's power is preserved within marriage, even in the absence of their traditional economic dominance.
