Research Misconduct in the Age of Open Science: The Case of STAP Stem Cells

In early 2014, Dr Haruko Obokata and her co-authors caused a global media storm by publishing two scientific papers in Nature on stem cells. The papers proposed a surprisingly simple new method called stimulus-triggered acquisition of pluripotency (STAP) to generate pluripotent stem cells for research purposes in a fast and inexpensive way. To the dismay of many, both papers were retracted within six months of their release due to data fabrication and falsification. The rise and fall of the STAP research illustrates the impacts of open science practices of quality control and validation on new scientific claims. In the STAP case, collective action generated through two online forums—the Knoepfler Lab Stem Cell Blog and PubPeer—exposed not only data manipulation in the two papers but also the irreproducibility of the purported new cellular reprogramming method. The case brings to the fore the tentative possibilities as well as potential pitfalls of ‘accelerated virtual witnessing’ through crowdsourced post-publication peer reviews that value accessibility and inclusiveness. Indeed, it calls for empirically grounded discussion on the ongoing reconfiguration of the shared system of values and norms or the moral economy of science.     

Buying and building success: Perceptions of organizational strategies for improvement

What makes people like a team? We suggest and test here whether people’s perceptions of teams and organizations differ as a function of the strategy the teams pick on their way to success. Two main strategies are compared: (1) Development is a strategy focused on building and enhancing the abilities of current team members; and (2) Acquisition is a strategy focused on buying talent from outside the organization. Does the way to success matter? In other words, will the strategy a team endorse affects how much people like the team? In five studies (N = 1,672) we tested whether people prefer teams that were successful by being (a) built through long-term development of team members or (b) bought by acquiring expensive personal developed elsewhere. Across the five studies, people preferred built teams over bought teams, including sport teams and law firms. Effort and group cohesion were more attributed to build than to bought teams. In a “mediators contest,” effort attributions proved most robust. People like built teams more than bought ones, mostly because they value the effort and hard work that built teams represent.     

虚拟健康社区医生贡献行为的形成机制

虚拟健康社区医生贡献行为(Doctor Contribution Behavior in Virtual Health Communities, V-DCB)在社会福祉创造中发挥着重要作用。从价值共创理论视角, 结合群体卷入模型和积极心理学研究, 提出在线服务交往中医生贡献行为前因后果的理论模型。首先从资源投入视角对V-DCB的概念和内涵进行分析, 并探讨测量工具的维度。接着分析社会交换和社会认同双重动机下的V-DCB行为卷入过程, 以及服务生态系统资源补充的激励作用。最后探讨V-DCB对医患双方幸福感共创的影响, 以及资源匹配因素对行为者幸福感产生的调节效应。     

What good leaders actually do: micro-level leadership behaviour,leader evaluations,and team decision quality

We supplement broad definitions of leadership behaviour with the concept of micro-level leadership behaviour, leaders’ verbal and non-verbal visible conduct and interaction. For the context of team decision-making, we identify two potentially beneficial micro-level leadership behaviours, question asking and behavioural mimicry. Specifically, we propose that under conditions of informational complexity and unshared information, participative leadership is most appropriate for team decision-making, that its effects are mediated by inquiring and empathy, and that question asking and mimicry are the behavioural micro-level manifestations of inquiring and empathy. We thus hypothesize that the effect of participative leadership on team decision quality and leader evaluation is mediated by question asking and mimicry. We conduct a laboratory experiment with student teams working on a hidden profile decision-making task and measure question asking through behavioural coding and mimicry with motion sensors. Results show that the effect of participative leadership on decision quality is mediated by question asking, and that the effect of participative leadership on leader evaluation as transformational is mediated by leaders’ behavioural mimicry and question asking. Under control of these micro-level behaviours, team decision quality and leader evaluations were unrelated.     

前瞻记忆类型差异及动机与任务序列对前瞻记忆的影响*

本文采用“模拟星期”范式通过3个实验分别考察了前瞻记忆任务类型的差异以及动机与任务序列对前瞻记忆的影响。结果表明：(1)规律性前瞻记忆任务的正确率显著高于非规律性的,即使本研究条件下对非规律性前瞻记忆任务进行奖励与惩罚,仍没有消除两者间的差异。(2)不论是惩罚还是奖励都可以显著提高非规律性前瞻记忆的成绩,而且动机促进作用会蔓延至非直接强化的前瞻记忆任务。(3)固定序列前瞻记忆成绩显著优于随机序列的,且在实验过程中固定序列前瞻记忆的成绩呈上升趋势,而随机序列的基本不变,固定序列在一定程度上反映了行为习惯的建立过程。(4)不论前瞻记忆任务规律与否,惩罚或奖励,任务序列如何,基于时间的前瞻记忆成绩均优于基于事件的前瞻记忆的成绩。(5)时间确认任务中,被试翻看时钟的次数与其正确率间呈显著正相关,且越临近规定时间翻看次数越多,呈J型分布。     

The Dynamics of Personality Approach (DPA): 20 Tenets for Uncovering the Causal Mechanisms of Personality

Over the last few decades, most personality psychology research has been focused on assessing personality via scores on a few broad traits and investigating how these scores predict various behaviours and outcomes. This approach does not seek to explain the causal mechanisms underlying human personality and thus falls short of explaining the proximal sources of traits as well as the variation of individuals' behaviour over time and across situations. On the basis of the commonalities shared by influential process-oriented personality theories and models, we describe a general dynamics of personality approach (DPA). The DPA relies heavily on theoretical principles applicable to complex adaptive systems that self-regulate via feedback mechanisms, and it parses the sources of personality in terms of various psychological functions relevant in different phases of self-regulation. Thus, we consider personality to be rooted in individual differences in various cognitive, emotional–motivational, and volitional functions, as well as their causal interactions. In this article, we lay out 20 tenets for the DPA that may serve as a guideline for integrative research in personality science. © 2020 The Authors.

The building blocks of shared leadership: The interactive effects of diversity types,team climate,and time

Despite the wealth of empirical studies and recent meta-analyses demonstrating the positive performance effects of shared leadership, knowledge regarding antecedents is limited. We draw upon a collective approach to leadership identity construction theory and team diversity in order to understand the member attributes that impact leadership sharing. We suggest that both informational/functional and social categorization diversity types are important dimensions when considering shared leadership antecedents. First, we suggest functional diversity will result in higher levels of shared leadership but will only be realized when teams elicit a cooperative climate. Second, we suggest that gender diversity, a salient social category, will have a negative impact on shared leadership, particularly in a low cooperative climate. We further hypothesize these effects will change over time as the positive effects of functional diversity strengthen and the negative effects of gender differences weaken. We test our hypotheses, including the impact on team performance, in a time-lagged sample of 267 undergraduate students in 73 teams competing in a complex business simulation and a constructive replication with 142 MBA students in 41 teams. Theoretical and practical implications are discussed.     

不同任务情境中虚拟团队绩效过程模式

运用模拟实验,通过操纵任务类型和任务依存性,考察了不同任务情境中虚拟团队的各种绩效过程模式及其演化过程。研究发现：（1）三种绩效过程模式对团队任务绩效具有不同的作用,在整个过程中,团队成员都能够设置比较客观的目标;而方法模式只在第一和第三阶段表现出显著作用;信任模式在第一和第二阶段的显著作用,表现出后期受到学习效应的干扰。（2）在概念性任务中,任务依存性对团队任务绩效作用显著,而在行为性任务中,其作用不显著,而且,任务依存性对不同任务类型中的绩效过程模式具有不同的作用。     

虚拟环境中临境感及其测量方法

虚拟环境（VE）中的临境感是用户感知身处VE而产生的一种主观体验,是评价VE的重要指标。VE临境感产生的基础在于个体VE某一特征的集中注意,其程度强弱在一定范围内取决于个体分配于VE的注意资源量,受诸如计算机技术设备等系统因素、表现为个体差异的用户因素以及人机对话过程中交互因素的影响。在此基础上本文从生理指标（生理测量法、心率变化和皮肤电阻变化）、行为指标（姿势变化和冲突条件下的刺激定位）、心理物理学（对比法和跨通道匹配法）、主观评价（WS-PQ、SUS-PQ、ITC-SOPI和直接主观评价法）和绩效衡量对VE临境感的测量方法进行总结和简单评价。
