社会价值取向与反馈对动态社会两难决策的影响：以水资源两难决策为例

以水资源两难情景为实验任务,探讨了社会价值取向与反馈在社会两难决策中的作用.结果表明: (1)社会价值取向在决策者的两难决策行为中起着非常重要的作用.合作型个体比非合作型个体显著地表现出更多的合作行为.个体的社会价值取向可以作为预测两难决策行为的一个重要因素: (2)不同的反馈类型对具有不同社会价值取向的决策者的决策行为影响不同.非合作型个体受反馈信息影响比较明显,而合作型个体则不易受他人的决策信息影响.     

It’s not just what you know, it’s who you know: Testing a model of the relative importance of social networks to academic performance

Applying three mathematical modeling techniques, this study proposes and tests the fit of an academic performance model, and then estimates the relative importance of four performance predictors: academic ability, performance goal orientation, educational technology use, and social network density. Drawing on social network theory, findings from this study show that social network density is a statistically important and unique predictor of academic performance, suggesting that “who you know” matters in large classroom settings. However, this study also indicates that academic ability is the most dominant factor in the explanation of academic performance. Practical and theoretical implications for enhancing academic performance through social networks are discussed.

大学生自我同一性状态与“大五”人格、因果取向的关系

通过对536名大学生的问卷调查,采用结构方程模型考察了大学生的自我同一性状态与"大五"人格、因果取向之间的关系。结果发现,(1)"大五"人格和因果取向均是大学生自我同一性状态的重要预测因素,能在较大程度上解释大学生所处自我同一性状态(特别是同一性获得状态和扩散状态)上的差异;(2)因果取向在"大五"人格对自我同一性状态的影响中起重要的中介作用。     

Demographic Indicators as Predictors of Future Time Perspective

The present investigation examined the relationships between five demographic variables (age, sex, income, marital status, and education) and future time perspective. From a theoretical perspective, these demographic indicators were conceptualized as proxy measures for the social forces that influence the adult expression of this personality dimension. Data were drawn from six investigations in which a brief measure of future time perspective (Hershey and Mowen in The Gerontologist 40:687–697, 2000) had been administered to one thousand four hundred and ninety eight individuals. Higher future time perspective scores (i.e., longer future orientations) were associated with being male, increased age, income, and educational level. These main effects, however, were mitigated by a significant three-way interaction among sex, age, and level of education. These findings suggest that a complex interplay of variables is responsible for the expression of personality traits at the individual level.     

Creativity and experience of a creative task: Person and environment effects

We examined the effects of a person factor (general causality orientation) and an environment factor (threat of evaluation) on creativity and personal experience of a creative collage-making task. Ninety college students completed questionnaires and made a collage under conditions of expected evaluation or no-evaluation. Creativity was a function of participants’ characterizations of themselves as artistic, and among men, of the interaction between environment and person factors. Task experience was affected by environment factors and, marginally, by the interaction of environment and person factors, with participants feeling less competent at the task under threat of evaluation, and exerting the greatest effort when they were under evaluation threat and were higher on control orientation. These findings may have implications for future motivation for creative tasks.     

Helping and proactive extra-role behaviors: The influence of motives, goal orientation, and social context

We explore how two motivational orientations (communion and status striving) influence three extra-role organizational behaviors: proactive engagement, providing help, and seeking help. We propose and confirm intervening mechanisms, in the form of (a) goal orientations and (b) attitudes toward coworkers. Proactive behaviors are predicted by status striving, through the intervening mechanisms of both learning and performance proving goal orientations. Providing help is, in turn, motivated by communion striving, and the relationship is mediated by goal orientations (learning and performance avoiding) and by satisfaction with and commitment to coworkers. Finally, seeking help is a function of communion striving, which influences the outcome through learning goal orientation and satisfaction with and confidence in coworkers.     

How fish do geometry in large and in small spaces

It has been shown that children and non-human animals seem to integrate geometric and featural information to different extents in order to reorient themselves in environments of different spatial scales. We trained fish (redtail splitfins, Xenotoca eiseni) to reorient to find a corner in a rectangular tank with a distinctive featural cue (a blue wall). Then we tested fish after displacement of the feature on another adjacent wall. In the large enclosure, fish chose the two corners with the feature, and also tended to choose among them the one that maintained the correct arrangement of the featural cue with respect to geometric sense (i.e. left-right position). In contrast, in the small enclosure, fish chose both the two corners with the features and the corner, without any feature, that maintained the correct metric arrangement of the walls with respect to geometric sense. Possible reasons for species differences in the use of geometric and non-geometric information are discussed.     

文字与图片呈现形成想象空间记忆的比较

学习通过文字或图片方式显示的空间布局材料之后,采用空间定位任务．分别检验在不同朝向和相对位置的条件下,对想象空间方位判断的差异。结果表明,使用图片进行空间布局的学习,记忆后再各自以同样显示形式进行空间定位任务时,判断的速度比使用文字的反应时要快;同时,无论是文字还是图片形式呈现．在进行想象转向时．都会呈现朝向效应和相对位置效应。     

虚拟团队学习效能研究:社会认知因素的影响

本研究采用现场研究的方法,对21个虚拟团队学习的效能进行了实证研究。研究对社会认知因素中的效能感和目标取向对虚拟团队学习效能(技能改变、工作任务和团队健康水平)的影响进行了研究,并探讨了对虚拟团队的态度在中间所起的作用。研究发现,虚拟团队效能感和学习取向对虚拟团队的学习效能产生作用,而对虚拟团队学习的态度、团队信任对虚拟团队学习的效能起着中介或直接的作用。
