Neck and Manz (1999) elaborated in their article “In Search of the Self-Lead Soldier” on the need for continuous improvement of personnel qualities such as increase in self-efficacy, increase of performance, and decrease of perceived strain. Self-leadership is a tool that fosters exactly these personal resources. This study examines self-leadership training effects on soldiers participating in a military training course over 14 weeks. It is the first self-leadership training study to evaluate performance improvement using objective criteria (examination marks, physical tests) in intervention and control group consisting of soldiers of the Austrian army. Its design features a large sample (N = 130), duration of self-leadership training over 10 weeks, and evaluation over 4 time points. The intervention group accomplished significantly higher educational achievements in examinations and physical tests. Also levels of self-efficacy were significantly higher and levels of strain were marginally to significantly lower. 相似文献

What Goes Up Apparently Needn't Come Down: Asymmetric Predictions of Ascent and Descent in Rankings 下载免费PDF全文
In eight studies, we document an upward mobility bias, or a tendency to predict that a rise in rankings is more likely than a decline. This asymmetry was observed in predictions of classroom performance, NBA and NFL standings, business school rankings, and employee performance rankings. The bias was found for entities people care about and want to see improve their standing, as well as entities in which people are not invested. It appears to result from people's tendency to give considerable weight to a focal agent's intentions and motivation, but to give less weight to the intentions of competitors and other factors that would thwart the focal agent's improvement. We show that this bias is most pronounced for implicit incremental theorists, who believe that performance is malleable (and hence assign more weight to intentions and effort). We discuss implications of this asymmetry for decision making and for an understanding of the underdog bias. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

Metacognition refers to the ability to discriminate between one’s own correct and incorrect decisions. The neurobiological underpinnings of metacognition have mainly been studied in perceptual decision-making. Here we investigated whether differences in brain structure predict individual variability in metacognitive sensitivity for visuomotor performance. Participants had to draw straight trajectories toward visual targets, which could unpredictably deviate around detection threshold, report such deviations when detected, and rate their confidence level for such reports. Structural brain MRI analyses revealed that larger gray-matter volume (GMV) in the left middle occipital gyrus, left medial parietal cortex, and right postcentral gyrus predicted higher deviation detection sensitivity. By contrast, larger GMV in the right prefrontal cortex but also right anterior insula and right fusiform gyrus predicted higher metacognitive sensitivity. These results extend past research by linking metacognitive sensitivity for visuomotor behavior to brain areas involved in action agency (insula), executive control (prefrontal cortex) and vision (fusiform). 相似文献

Coordination in health care action teams is an important factor in clinical performance and patient safety. Implementing a high-fidelity in situ simulation study, we investigated the performance-relevant effects of task distribution, provide information without request (PIWR) and closed-loop communication (CLC) in 68 medical emergency teams (METs) composed of fully qualified clinicians. We differentiated between two task types: algorithm-driven and knowledge-driven tasks. We assigned two different emergency tasks to each task type. We proposed not only a direct relationship between the three coordination behaviours and clinical performance, but also a moderating role for the type of task. Only CLC was related to performance and also moderated by task type. There was no relationship between the coordination behaviours task distribution and PIWR and performance. We discuss the differential effects of the three coordination behaviours on performance and emphasize the importance of the task in team research. In particular, we highlight theoretical and practical implications. 相似文献

The personality factor of extraversion has been associated with performance in some occupations (e.g., sales), and it has been one of the most consistent personality predictors of leadership. Recent research indicates that extraversion could have a non-linear relation with performance. At the same time, many researchers have contended that scholars should utilize measures of personality narrower than factors and that the bandwidth and relevance of personality should fit both the criterion and the context of a study. We argue and find that by examining an aspect of extraversion (i.e., social potency) in a particular vocational context (i.e., enterprising job demands), non-linear, asymptotic (diminishing marginal benefits) effects will be demonstrated on a relevant type of performance (i.e., enterprising job performance). We review implications, limitations, and avenues for future research. 相似文献

In newly formed groups, informal hierarchies emerge automatically and readily. In this study, we argue that emergent group hierarchies enhance group performance (Hypothesis 1) and we assume that the more the power hierarchy within a group corresponds to the task‐competence differences of the individual group members, the better the group performs (Hypothesis 2). Twelve three‐person groups and 28 four‐person groups were investigated while solving the Winter Survival Task. Results show that emerging power hierarchies positively impact group performance but the alignment between task‐competence and power hierarchy did not affect group performance. Thus, emergent power hierarchies are beneficial for group performance and although they were on average created around individual group members' competence, this correspondence was not a prerequisite for better group performance. 相似文献

通过文献研究和哲学反思等方法对高校和医疗卫生系统的量化绩效考核进行研究。认为绩效考核不能偏离组织使命,不能弱化职业精神。如何在职业精神和组织使命中一些重要内容难以进入量化指标的情况下合理设计绩效考核体系值得深思。其次,在科研绩效考核中,《科学引文索引》(science citation index,SCI)作为科研论文的产出指标有一定合理性,但也不能唯SCI论;要重视基金,因为它反映了计划性科学的价值,但也不能唯基金论;要重视量化评估,却不能唯量化评估。要保证绩效考核正确导向,就必须纠正泛行政化和官本位倾向,就必须坚持科学化、推进民主化。 相似文献

This study explores the impact of post‐earthquake images inserted in a vigilance task, in terms of performance, self‐reports of task‐focus, and cerebral activity using functional near‐infrared spectroscopy (fNIRS). Vigilance tasks present a sequence of stimuli in which only a few are pre‐designated critical or target stimuli requiring an overt response from the participant. Seventy‐one residents participated (51 women, 20 men) by taking part in a vigilance task with task‐irrelevant images inserted in the sequence. There were three conditions consisting positive (emotive inducing), negative (emotive inducing), and control (devoid of meaning) images embedded in the vigilance task to assess possible impacts on vigilance performance. The images were obtained through crowdsourcing and represented parts of the city 3–4 years post‐earthquake. Task performance was assessed with signal detection theory metrics of sensitivity A’ and bias β’’. This enables the separation of an individual's ability to accurately discriminate critical signals from non‐critical stimuli (sensitivity) and shifts in their willingness to respond to any stimuli whether critical or not (bias). Individuals viewing the positive images, relating to progress, rebuild, or aesthetic aspects within the city, had a more conservative response bias (they responded less to both rare critical and distractor stimuli) than those in the other conditions. These individuals also reported lower task‐focus, as would be expected. However, contrary to expectations, indicators of cerebral activity (fNIRS) did not differ significantly between the experimental groups. These results, when combined, suggest that mind wandering events may be being generated when exposed to positive post‐earthquake images. 相似文献
