These studies examined the relations among performance satisfaction, choice of social comparison targets, and subsequent performance in a classroom setting. Previous research has shown that comparison with high performers helps academic performance. In 2 field studies, this relation was moderated by satisfaction with initial performance. After learning their scores on the first exam of the semester, students indicated their satisfaction with the scores and performance level of someone with whom they would like to compare exams. Comparison with poor performers was beneficial when coupled with dissatisfaction. Dissatisfied students who preferred comparison with poor performers improved over the semester. 相似文献

A social dynamics perspective of aggression in school is presented. This framework focuses on the role of natural social processes in the establishment and maintenance of aggressive behavior in the school context. The five articles in this special issue are briefly reviewed and a synthesis of their contributions for understanding the social dynamics of aggression in school is underscored. Future research and intervention implications are also discussed. The need for examining the role of school social dynamics in conducting social skills interventions, functional behavioral assessments, and the development of positive behavioral support plans is emphasized. 相似文献

本文分析荷兰神学家亚伯拉罕·凯伯和美国神学家马克斯?斯塔克豪思在理解和促进神学与社会生活关联上各自的贡献:前者以"普遍恩典"和"领域主权"的观念为中心,后者则以"全球化与恩典"为考察重点。两者的公共神学存在着一定的思想联系,本文将进一步探析凯伯对斯塔克豪思的影响。这一研究意在表明公共生活领域对于神学思考的重要性,而时代的处境会提出神学必须面对的不同公共议题及其指向的特定神学信念和方法。 相似文献

The status quo effect derived from loss aversion is common in decision making. However, we propose that advisors (vs. personal decision makers) are less susceptible to such an effect because they are less loss-averse. The difference in loss aversion between personal decision makers and advisors is reflected in both the query order and content. Compared to advisors, personal decision makers produce more queries favoring the status quo, at an earlier time, than those favoring the new option. As hypothesized, the status quo effect was observed among personal decision makers, but not among advisors (Studies 1 and 2). Query order and content were found to mediate the impact of decision maker’s role on the status quo effect (Study 2). When personal decision makers and advisors made queries in the same order (Study 3) or of the same content (Studies 4a and 4b), the difference between self–other decision making disappeared. 相似文献

The concept of capacity has become increasingly important in discussions of working memory (WM), in so far as most models of WM conceptualize it as a limited-capacity mechanism for maintaining information in an active state, and as capacity estimates from at least one type of WM task—complex span—are valid predictors of real-world cognitive performance. However, the term capacity is also often used in the context of a distinct set of WM tasks, change detection, and may or may not refer to the same cognitive capability. We here develop maximum-likelihood models of capacity from each of these tasks—as well as from a third WM task that places heavy demands on cognitive control, the self-ordered WM task (SOT)—and show that the capacity estimates from change detection and complex span tasks are not correlated with each other, although capacity estimates from change detection tasks do correlate with those from the SOT. Furthermore, exploratory factor analysis confirmed that performance on the SOT and change detection load on the same factor, with performance on our complex span task loading on its own factor. These findings suggest that at least two distinct cognitive capabilities underlie the concept of WM capacity as it applies to each of these three tasks. 相似文献

Microstructure and deformation mechanisms at a nanoindentation in the lamellar colony of high Nb containing TiAl alloy have been studied using the focused ion beam and the transmission electron microscopy. Considerable deformation twins are observed around the nanoindentation, and a strain gradient is generated. A continuous change in the bending angle of the lamellar structure can be derived, and a strain-induced grain refinement process is observed as various active deformations split the γ grains into subgrains. In addition to all possible deformation mechanisms (ordinary dislocation, super-dislocation and deformation twining) activated due to the heavy plastic deformation, a 6-layer hexagonal (6H) long-period stacking ordered structure is identified for the first time near the contact zone and is thought to be closely related to the glide of partial dislocations. 相似文献
