“近朱者赤”：同事主动行为如何激发员工动机和绩效

以往有关主动性的研究通常聚焦员工本身, 忽略了团队或组织中同事会对员工行为产生影响这一重要管理实践和理论视角。为此, 本研究以社会学习理论为基础, 探讨了同事主动行为对员工自主动机和工作绩效的影响, 以及员工主动性人格的调节作用。通过多时点、上下级匹配问卷(研究1)及情景实验(研究2)两项研究, 本文发现, 同事主动行为可以激发员工的自主动机, 进而提升工作绩效; 并且, 员工主动性人格强化了同事主动行为对员工自主动机的正向作用。本研究不仅从理论上将现有关于主动行为的研究视角迁移到同事, 也为如何更好地激励员工提供了实践指导。     

Emotion Regulation as a Moderator of Outcomes of Transdiagnostic Group Cognitive-Behavioral Therapy for Emotional Disorders

The aim of this study was to examine the potential moderating effect of baseline emotion regulation skills—cognitive reappraisal and expressive suppression—on the relationship between treatment allocation and treatment outcomes in primary care patients with emotional symptoms. A total of 631 participants completed scales to evaluate emotion regulation, anxiety, depression, functioning, and quality of life (QOL). The moderation analysis was carried out using the SPSS PROCESS macro, version 3.5. Expressive suppression was a significant moderator in the relationship between treatment allocation and treatment outcomes in terms of symptoms of anxiety (b = −0.530, p = .026), depression (b = −0.812, p = .004), and QOL (b = 0.156, p = .048). Cognitive reappraisal acted as a moderator only in terms of QOL (b = 0.217, p = .028). The findings of this study show that participants with higher scores of expressive suppression benefited more from the addition of transdiagnostic cognitive-behavioral therapy to treatment as usual (TAU) in terms of anxiety and depressive symptoms, and QOL. Individuals with higher levels of cognitive reappraisal obtained a greater benefit in terms of QOL from the addition of psychological treatment to TAU. These results underscore the relevant role that emotion regulation skills play in the outcomes of psychological therapy for emotional symptoms.     

Executive functions,math anxiety and math performance in middle school students

Previous studies mainly investigated working memory (WM) and math anxiety (MA) leaving almost unexplored other aspects of executive functions (EFs) in middle school period. Filling the gap in the literature, the aims of this study were: (1) to better examine the relationship between MA and math performance, (2) to better examine the relationship between EFs and math performance and (3) to investigate the interplay between EFs and MA on math performances. This study confirmed a significant and negative relationship between MA and math performance, indicates a significant and positive relationship between visuospatial WM and math performance, shifting and math performance and highlight a scarcely investigated indirect influence of MA through the measure of shifting on math performance. Our findings shed further light on the mediating role of EFs between MA and math performance and underline some future perspectives.     

毅力人格与数学成绩之间的关系以及学习行为投入的中介作用:以PISA 2012中国上海数据为例

通过分析PISA 2012中国上海中学生样本,探讨毅力人格对数学成绩的影响,尤其是学习行为投入的中介作用。结果显示,毅力人格包含了代表缺乏毅力、容易放弃的负性维度,以及代表富有毅力、追求完美的正性维度。负性维度能负向预测数学成绩,学习行为投入起部分中介作用。正性维度对数学成绩的总效应和直接效应不显著,只通过学习行为投入产生正向间接影响。负性维度对数学成绩的负面影响整体强于正性维度的正面作用。因此教学中对数学成绩不佳的学生,应根据其毅力水平给予不同引导。     

The relationship between simulator sickness and driving performance in a high-fidelity simulator

Driving simulators are highly valuable tools for various applications such as research, training, and rehabilitation. However, they are also known to cause simulator sickness, a special form of traditional motion sickness. Common side effects of simulator sickness include nausea, headache, dizziness, eye-strain, and/or disorientation, all symptoms which may negatively impact driving performance. The goal of the present study was to investigate the relationship between simulator sickness and driving performance obtained in a high-fidelity driving simulator. Twenty-one healthy participants were engaged in a simulated driving task containing rural, city, and highway sections for approx. 25 min. Participants were asked to drive naturally while obeying traffic rules and completing common driving maneuvers (including reactions to sudden events). Driving performance was evaluated based on various driving measures, such as lane positioning, speed measures, following distance, or the number of steering reversals. Simulator sickness was measured before, during, and after the simulated drive using a combination of the Simulator Sickness Questionnaire and the Fast Motion Sickness scale. Overall, correlations between the level of simulator sickness and driving performance measures were low to moderate (r’s from -0.37 to 0.40) and were not significant. Additionally, participants who reported higher levels of simulator sickness did not differ with regards to their driving performance from those who reported lower simulator sickness scores. Our results suggest that the presence of simulator sickness is not strongly related to performance in a driving simulator.     

An evaluation of the effectiveness of countermeasures for improving the safety of dilemma zones: A driving simulator study

The main objective of this driving simulator study is to analyze the behavior of the driver at the start of the yellow signal of a signalized rural intersection and identify the most effective countermeasures for tackling the dilemma zone, namely an area on the intersection approach where vehicles at the start of the yellow phase can neither safely stop before the stop line nor cross the intersection. The following countermeasures were tested in the study on a sample of 48 drivers: green signal countdown timers, GSCT (C₁); a new pattern of vertical and horizontal warning signs (C₂); and an advanced on-board driver assistance system based on augmented reality (AR) and connected vehicle technologies (C₃). These countermeasures were tested and compared to a baseline condition (B) where no countermeasures were applied. Based on the results of this study, the C₂ and C₃ countermeasures have proven to be valid tools for reducing driver indecision when approaching signalized intersections at the start of the yellow signal. In fact, using C₂ and C₃, the length of the dilemma zone was equal to 30 m and 36 m, respectively, with a reduction of about 50%, as compared to the baseline condition (B). Moreover, a reduced number of false behaviors was recorded, as well as a greater consistency in driver decision-making behaviors. Conversely, the C₁ countermeasure did not lead to a significant improvement in the dilemma zone: an unnecessary increase in early stop rates was recorded, resulting in reduced intersection efficiency and operations.     

Resilience and Subjective Wellbeing: A Psychometric Evaluation in Young Australian Adults

Objective

Resilience is an important and underdeveloped area of research, and there are few studies that describe levels of resilience among youth samples. A major aim of this research is to explore the utility of an adapted form of the 10‐item Connor Davidson Resilience Scale and to clarify the association between this construct and a robust measure of subjective wellbeing.

Method

A representative sample of 1000 Victorians aged 16–25 years participated in a telephone interview comprising the modified 10‐item Connor Davidson Resilience Scale and the Personal Wellbeing Index.

Results

The modified 10‐item Connor Davidson Resilience Scale demonstrated adequate inter‐item reliability and factored as intended. A moderate, positive correlation was found between the modified 10‐item Connor Davidson Resilience Scale and the Personal Wellbeing Index. Significance testing revealed group differences for gender, age, and annual household income. The results are also used to establish theoretical “normal” ranges for resilience in Victoria's youth population.

Conclusion

The results from this study support the modified 10‐item Connor Davidson Resilience Scale as a valid and reliable measure of young people's resilience using traditional psychometric tests. Moreover, this is the first study to describe the levels of resilience among Victorian youths and to evaluate these data alongside a robust measure of subjective wellbeing. The implications of the findings for government policy and service delivery are discussed.     

Collective‐efficacy as a mediator of the relationship of leaders' personality traits and team performance: A cross‐level analysis

The relationship between a leader's personality and his team's performance has been established in organisational research, but the underlying process and mechanism responsible for this effect have not been fully explored. Both the traditional multiple linear regression and the multilevel structural equation model approaches were used in this study to test a proposed mediating model of subordinates' perception of collective efficacy between leader personality and team performance. The results show that the team leader's extraversion and conscientiousness personality traits were related positively to both the team‐average (individual) perception of collective efficacy and team performance, and the collective efficacy mediated the relationship of the leader's personality traits and team performance. This study also discusses how Chinese cultural elements play a role in such a mediating model.     

Musical Training,Bilingualism, and Executive Function: A Closer Look at Task Switching and Dual‐Task Performance

This study investigated whether musical training and bilingualism are associated with enhancements in specific components of executive function, namely, task switching and dual‐task performance. Participants (n = 153) belonging to one of four groups (monolingual musician, bilingual musician, bilingual non‐musician, or monolingual non‐musician) were matched on age and socioeconomic status and administered task switching and dual‐task paradigms. Results demonstrated reduced global and local switch costs in musicians compared with non‐musicians, suggesting that musical training can contribute to increased efficiency in the ability to shift flexibly between mental sets. On dual‐task performance, musicians also outperformed non‐musicians. There was neither a cognitive advantage for bilinguals relative to monolinguals, nor an interaction between music and language to suggest additive effects of both types of experience. These findings demonstrate that long‐term musical training is associated with improvements in task switching and dual‐task performance.     

A Self‐regulation Perspective on Hidden‐profile Problems: If–Then Planning to Review Information Improves Group Decisions

In hidden‐profile (HP) problems, groups squander their potential to make superior decisions because members fail to capitalize on each other's unique knowledge (unshared information). A new self‐regulation perspective suggests that hindrances in goal striving (e.g., failing to seize action opportunities) contribute to this problem. Implementation intentions (if–then plans) are known to help deal with hindrances in goal striving; therefore, supporting decision goals with if–then plans should improve the impact of unshared information on group decisions. Indeed, in line with past research, control participants in two experiments rarely identified the best alternative despite monetary incentives and setting decision goals. In contrast, simply adding if–then plans to review advantages of the non‐preferred alternatives before making the final decision significantly increased solution rates. Process manipulations (Experiment 1) and measures (Experiment 2) indicate that conceptualizing HP problems as a self‐regulation challenge provides explanatory power beyond existing accounts.
