运用双任务实验范式,比较了三种认知负荷主观评价量表的灵敏度与效度。结果发现:在本研究任务条件下,次任务反应时的稳定性、抗干扰性较好,可以作为认知负荷主观评价的标尺;WP量表与PAAS量表的敏感性均较好,其中WP量表的敏感性、诊断性高于后者,TLX量表的敏感性较弱;WP量表与PAAS量表的效度较好,且好于TLX量表。综合各项指标,在中低难度任务下,WP量表是目前认知负荷较为理想的测量工具。 相似文献

本研究从工作记忆容量的角度入手,探讨数学焦虑对工作记忆子系统及数学心算成绩的影响,并寻求三者之间关系的理论解释。本研究为3×2×2混合实验设计,即三组被试(高、中、低数学焦虑组)、工作记忆两个子系统(言语工作记忆和视空间工作记忆)和两种数学心算任务难度,并记录数学心算的反应时和正确率作为其成绩指标。结果表明在要求较高工作记忆容量的数学心算任务中,数学焦虑通过言语工作记忆和视空间工作记忆都会对数学心算成绩产生影响,其中视空间工作记忆是数学焦虑与复杂数学心算反应时之间的中介变量。 相似文献

通过文献检索及对43名高校校长及其直接下属的访谈,经专家讨论,编制了中国高校校长变革型领导行为量表。515份数据的探索性因素分析和461份数据的验证性因素分析结果表明,中国高校校长的变革型领导行为是五因素结构,即德行垂范、关怀激发、愿景激励、领导魅力、团结协作。问卷具有良好的信效度。回归分析结果表明,高校校长的变革型领导行为对教师组织承诺具有正向影响,其中,教师的内部动机与学校的组织氛围对二者的关系具有完全中介作用。 相似文献

采用单探测变化检测范式,考察了单维度特征图形在视觉客体和视觉空间工作记忆中的存储机制,并对这两种视觉工作记忆的容量进行测定。结果显示,在客体工作记忆中,规则图形的记忆成绩显著高于不规则图形,但在空间工作记忆中,这两种图形的记忆成绩无显著差异;空间工作记忆的存储容量显著大于客体工作记忆容量,分别为4-5个位置和3-4个客体。这表明,图形规则性影响了客体工作记忆的存储但不影响空间工作记忆的存储,由单维度特征组成的图形在客体工作记忆中是以特征为单元储存,而在空间工作记忆中是以整合方式储存。 相似文献

The purpose of the current study is to examine the cross‐level three‐way interactions among individual trait positive affect (PA), group trait PA, and group PA diversity on individual work outcomes. Drawing on situation strength theory, we hypothesized that the relationship of individual trait PA with work outcomes depends on the strength of a group's affective contexts including group trait PA and PA diversity. The hierarchical linear modelling results for 261 employees in 42 South Korean organizational teams showed that individuals' trait PA was positively associated with their team commitment, job satisfaction, and organizational citizenship behaviour (OCB). The findings also demonstrated that individual trait PA had the strongest relationship with team commitment when group trait PA was low and PA diversity was high simultaneously. In addition, the relationship between individual trait PA and OCB was found to be stronger for affectively diverse groups than for homogeneous groups. 相似文献

This study investigated gender differences in anxiety and coping styles under the stress of intense military training. We surveyed Chinese female (n = 470) and male (n = 379) military officers who were surveyed during the third month of a 10-month intensive training program. Results indicated that state and trait anxiety were highly correlated in both women and men. In general, female officers had higher levels of anxiety, greater negative coping tendencies, and less perceived self-efficacy than their male counterparts. When compared with the norm, both women and men had significantly more positive coping strategies. A hierarchical multiple regression analysis showed factors that influenced male and female state anxiety. Avoidance, which was chosen by women more often than men, in general was less useful for female officers. The most common positive coping style for female officers was problem solving, whereas for men it was help seeking. We suggested that even female officers with lower mental health levels than their male counterparts made active cognitive changes to their coping styles when undergoing intense military training. 相似文献

People tend to judge others to be more similar to themselves than themselves are to others. This self–other similarity judgment asymmetry was often explained by a cognitive model. However, some findings were inconsistent with this model, implying that there might be complementary processes underlying such asymmetry. Although a motivational explanation has been proposed to account for the asymmetry, little evidence has been accumulated to verify this explanation and differentiate it from the cognitive model. The current research tested both the core assumption of the motivational explanation as well as a hypothesis derived only from it. Results suggest that the perception of oneself as being similar to others was more threatening to people's uniqueness than the perception of others as being similar to oneself. Individuals with high need for uniqueness exhibited greater asymmetry than did individuals with low need. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

Ecological Themes in Evangelii Gaudium,Together towards Life,and The Cape Town Commitment for Fraternity with God's Creation

The main purpose of this study is to explore the Christian response to the current ecological crisis by examining three statements using a method of theological reflection: Evangelii Gaudium (EG), Together towards Life (TTL), and The Cape Town Commitment (CTC). The three statements request Christians’ care for creation, which is now threatened. In contemplating the ecological crisis, the three statements call attention to the widespread abuse and destruction of the Earth due to an economic system that accelerates consumerism and human greed. To overcome this ecological crisis, Pope Francis recalls the joy of the gospel overflowing from the Trinity; TTL and CTC echo this, drawing their faith tradition from the Trinity with widening understanding of God who is creator, redeemer, and sustainer. The three statements also identify the rest of creation as the new poor in order to recall that the suffering of the poor and the suffering of the earth are one, inseparable from the suffering of Jesus. Finally, this study examines the three statements in relation to the spirituality of ecological themes. In particular, EG and TTL discern a false spirituality that is a form of individualism and a theology of prosperity, but suggest a spirituality that is referred to as either transformative spirituality or mystical fraternity. The study concludes that it is time to turn to the cosmological dimension of spirituality and theology for fraternity with God's creation and the future of the earth community. 相似文献
