Working Memory Training Improves Dual-Task Performance on Motor Tasks

The authors investigated whether working memory training improves motor-motor dual-task performance consisted of upper and lower limb tasks. The upper limb task was a simple reaction task and the lower limb task was an isometric knee extension task. 45 participants (age = 21.8 ± 1.6 years) were classified into a working memory training group (WM-TRG), dual-task training group, or control group. The training duration was 2 weeks (15 min, 4 times/week). Our results indicated that working memory capacity increased significantly only in the WM-TRG. Dual-task performance improved in the WM-TRG and dual-task training group. Our study provides the novel insight that working memory training improves dual-task performance without specific training on the target motor task.     

Shame as a predictor of post-event rumination in social anxiety

Evidence shows that people with high social anxiety levels ruminate about distressing social events, which contributes to the maintenance of social anxiety symptoms. The present study aimed to explore the role of shame in maintaining post-event rumination (PER) following a negative social event (an impromptu speech with negative feedback) in a student sample (N?=?104). Participants reported negative rumination related to the event one day and one week after the speech. PER measured one day after the speech was not associated with social anxiety symptoms and state anxiety. One week later, participants with clinically relevant social anxiety symptoms experienced greater PER. State shame was the only significant predictor of PER in a regression equation that also included social anxiety symptoms, state anxiety and self-evaluation of performance. Possible explanations and implications are discussed in light of cognitive models of social anxiety.     

复杂情境下不同角度及思维方式的决策表现差异:决策视角-心理距离的作用

本研究运用2个行为实验探讨了复杂情境下自我决策、为他人决策和预期他人决策在无意识思维方式和有意识思维方式下的决策表现差异。实验1发现复杂情境中无意识思维方式下,自我决策和为他人决策的决策表现显著优于预期他人决策,自我决策和为他人决策表现没有显著差异。实验2发现复杂情境中有意识思维时,在陌生人条件下,为他人决策表现分数显著高于自我决策与预期他人决策,自我决策和预期他人决策表现无显著差异;在朋友条件下,为他人决策和预期他人决策的决策表现显著优于自我决策,为他人决策和预期他人决策表现无显著差异。研究结果支持了本文提出的决策视角-心理距离作用假设(the Perspective-Distance Effect Hypothesis,PDEH)。     

信任氛围、内部人身份认知与员工角色内绩效:中介的调节效应

虽然已有研究从逻辑上推理内部人身份认知在信任氛围与角色内绩效之间起中介作用,但却极少给出实证的结果。本研究基于角色认同理论和自我认知理论,以31家生产型企业的330员工为调查对象,从心理安全感的视角对信任氛围是否以及如何通过内部人身份认知影响角色内绩效进行了实证研究。结果显示:1)信任氛围对员工角色内绩效具有正向影响;2)内部人身份认知部分中介信任氛围对员工角色内绩效的影响;3)心理安全感在信任氛围与内部人身份认知的关系中起调节作用;进一步,4)心理安全感调节了内部人身份认知对信任氛围-角色内绩效中介作用。研究证明了被中介的调节效应模型全新地解释了信任氛围对角色内绩效的作用机理,对员工创新绩效管理实践提供有益的启示。     

规则适应视角下辱虐管理的成因机制

基于规则适应及资源依赖理论的解释视角,本研究考察了下属工作绩效与政治技能对上级辱虐的影响。通过对采集自两家企业的243对领导-下属的配对问卷进行分析,本研究的多项式回归与响应面分析表明,当下属的工作绩效(遵循做事显规则)与政治技能(遵循做人潜规则)在较高水平上保持一致时,其遭受的上级辱虐最少。但这种较高水平的一致只能维持在特定范围内,当两者过高时,反而易遭致上级的辱虐行为。同时,在工作绩效与政治技能存在差异的情境下,相比于"高工作绩效,低政治技能"的下属,"低工作绩效,高政治技能"的下属遭受的上级辱虐要更少。文章分析并证明了遵循不同规则的下属会导致不同程度的上级辱虐。     

Employable,committed, and thus well-performing: a matter of interdependent forward-looking social exchange

This study probes the relationship between perceived external employability (i.e., the individual’s perception of available jobs on the external labour market) and affective commitment and performance within the framework of social exchange. An innovative feature is that we advance perceived external employability as a commodity of interdependent forward-looking exchange: employees who perceive themselves as externally employable anticipate successful exchange, which drives further responses, both relational (i.e., affective organizational commitment) and behavioural (i.e., performance). Strong features of this study are that we include (a) both the organization and the workgroup as foci of affective commitment, and (b) task, helping, and counterproductive behaviour as indicators of performance. Results from cross-lagged, structural equation modelling (SEM) analyses on two-wave survey data (N = 458 Belgian employees) largely align with our idea: perceived external employability has a positive cross-lagged effect on affective organizational and workgroup commitment. The two foci of commitment in turn have a cross-lagged effect on performance, positive in the case of helping behaviour and negative in the case of counterproductive behaviour. No significant cross-lagged effects were found in relation to task behaviour. We discuss these results in the light of Social Exchange Theory and potential routes for future research.     

Core self-evaluations as a moderator of the relationship between task complexity,job resources,and performance

In this study we examined the role of trait core self-evaluations (CSE) as a person-related resource, hypothesizing that the relationship between task complexity and performance would be positive for people high in trait CSE and negative for people low in trait CSE. Moreover, we hypothesized that trait CSE would influence the buffering effect of job-related resources on the complexity–performance relationship, with such a buffering effect showing for people high but not for people low in trait CSE. To test our hypotheses, we conducted a five-day spanning experience sampling study. Our results showed that trait CSE indeed influenced the complexity–performance relationship in the sense that this relationship was only positive for employees high in CSE. Results on the hypothesized three-way interaction between task complexity, job-related resources, and CSE were less univocal as only one out of four three-way interactions approached conventional levels of significance. By showing that the complexity–performance relationship is only positive for employees high in CSE, our results go against the well-accepted idea that challenge demands act as a two-edged sword for all employees alike. Instead, the effect of challenge demands on performance depends on the individual’s level of person-related resources.     

Reflections of the student teacher

This paper explores the concept of reflection and its changing role in the journey of the student teacher. It presents part of the findings of a year-long investigation into the reflective practice of student teachers during their training year. Specifically, it investigates the reflections of the student teachers’ lessons during the PGCE (Post/Professional Graduate Certificate of Education) year at a higher education institution (HEI) in England. The strengths and weaknesses of the student teachers’ lessons are analysed and how these reflections change as they reach Newly Qualified Teachers (NQT) status.     

Skills,training, and activism

Most studies of activism and social movements give more attention to methods and strategies than to the development of skills. Yet skills are crucially important to the success of campaigns. Research on expert performance provides insights into what is required to become highly proficient at a well-defined set of skills. These insights are potentially relevant to activists, as shown by the example of training for lunch-counter sit-ins in Nashville, Tennessee in 1960. Skill development needs to be given greater attention by activists and scholars.     

Prior self-control exertion and perceptions of pain during a physically demanding task

ObjectivesExertion of self-control has been associated with impaired performance on subsequent physical tasks also requiring self-control, but it remains unknown why this occurs. This study, therefore, explored whether a) prior self-control exertion reduces subsequent persistence on a physically demanding task, and b) whether any observed performance decrements could be explained by changes in perceptions of pain.MethodIn a within-subject design, sixty-three individuals completed an easy (congruent) Stroop task or a difficult (incongruent) Stroop task that required self-control. Participants were then required to remain in a physically demanding posture (i.e., a ‘wall-sit’) until voluntary exhaustion and their perception of pain was recorded during the task.ResultsWhen participants completed the difficult Stroop task, they quit the wall-sit sooner. This decrement in performance was explained by greater perceptions of pain at the beginning of the wall-sit.ConclusionsPerceptions of pain may, therefore, be an important attentional mechanism explaining why self-control use interferes with subsequent persistence during physically effortful tasks.
