研究一,采用单因素组间设计(合作组、名义组、个人组)检验创造性任务情境下是否存在社会惰化效应,结果显示:合作组状态下个体努力水平显著低于名义组,与个人组差异不显著;研究二,采用三因素组间设计(4×2×3)探讨创造性任务情境下社会惰化影响因素,结果显示:目标难度、绩效评估变量主效应显著且存在交互作用,而中期评估变量主效应不显著。研究结果提示:高难度目标、评估个体对群体的贡献可减弱创造性任务情境下的社会惰化效应。 相似文献

Although recent research highlights the role of team member goal orientation in team functioning, research has neglected the effects of diversity in goal orientation. In a laboratory study with groups working on a problem-solving task, we show that diversity in learning and performance orientation are related to decreased group performance. Moreover, we find that the effect of diversity in learning orientation is mediated by group information elaboration and the effect of diversity in performance orientation by group efficiency. In addition, we demonstrate that team reflexivity can counteract the negative effects of diversity in goal orientation. These results suggest that models of goal orientation in groups should incorporate the effects of diversity in goal orientation. 相似文献

This longitudinal study examined the relative associations of initial levels of hope and optimism with subsequent academic performance and life satisfaction among first-year law students (N = 86). Path analysis showed that hope, but not optimism, predicted better academic performance, while controlling for Law School Admission Test scores and undergraduate grades. Both hope and optimism uniquely predicted greater life satisfaction at the end of the first semester. 相似文献

The present study sought to use stilt walking as a model to uncover modifications to gait dynamics caused by changes in lower limb anthropometrics. We examined 10 novice and 10 expert stilt walkers, each walking with and without stilts, to determine the specific adaptations brought about by experience. Three-dimensional kinematics and force platform data were used to calculate the intersegmental forces, net joint moments and moment powers at the ankle, knee and hip. Spatio-temporal data were computed to aid the interpretation of these data. Non-dimensional scaling was used to facilitate comparison between stilt- and normal-walking. In general, the stilts induced largely the same alterations in the locomotor patterns of both novices and experts, which did not allow for the conclusion that the experts employed locomotor dynamics that were better suited to the challenges imposed by alterations to limb length, mass and mass moment of inertia induced by the stilts. Nevertheless, the experts exhibited a lesser reduction in dimensionless stride length and velocity and generated larger concentric knee flexor and hip extensor powers, relative to the novices, which may be indicative of enhanced dynamic stability control. 相似文献

Although personality assessment has proven utility in pre-employment testing, little is known about how one should choose the personality traits that are most job-related. We developed a Personality-oriented Job Analysis (POJA) process for choosing job-related personality traits. We evaluated this process using 15 expert raters and approximately 330 medical students who each completed six different “jobs” in which their performance was evaluated. There was consistency across experts in POJA ratings of the job-relevance of personality traits. Also, POJA ratings of the personality traits correlated with the actual criterion-validity of the traits. Traits that received the highest POJA ratings tended to predict job performance. To our knowledge, this is the first published work to present evidence of the criterion-validity of POJA. 相似文献

Much research has examined how stereotype threat leads to the underperformance of stereotyped targets. The underlying cause for this effect, however, remains unclear. Some researchers argue that stereotype threat can be explained from a behavioral-priming perspective, while others claim that it necessarily involves concerns about confirming a negative self-relevant stereotype. The current experiment highlights the critical role of self-relevance in distinguishing between stereotype priming and stereotype threat. Results showed that when participants wrote about a stereotyped target from a first-person perspective, both targets and non-targets performed poorly under stereotype threat conditions, because writing from a first-person perspective made the stereotype self-relevant for non-targets. But when participants wrote about a stereotyped target from a third-person perspective, only targets underperformed since the stereotype was already self-relevant. Moreover, when the stereotype was made self-relevant non-targets experienced the same threat-based concerns that targets experience under stereotype threat conditions. 相似文献

Measurement of performance is extremely important for not-for-profit agencies in terms of measuring the efficiency and effectiveness
of agencies in achieving their goals. Performance indicators assist managers of agencies in strategic decision making and
in fulfilling their accountability obligations for the best use of limited resources. This paper argues that not-for-profit
agencies that serve people with intellectual disabilities can use quality of life as one measure of agency and/or program
performance. This is demonstrated with reference to research conducted on the effect of different methods of employment on
the quality of life for people with intellectual disabilities. Effectiveness of agencies and/or programs can be assessed based
on comparisons of quality of life outcomes under different methods of employment or by reference to absolute percentage of
scale maximum scores and whether homeostasis is defeated. 相似文献
