Effects of rater conscientiousness on evaluations of task and contextual performance of older and younger co-workers

The possibility for age discrimination and stereotypes to affect performance evaluations is rising. Although careful evaluations might be expected from conscientious raters, little is known about whether they might show more or less bias towards certain age groups. Therefore, in our study using a time-lagged design, we investigated the effects of rater conscientiousness on the performance evaluations of younger and older actual co-worker (N = 242). We found that raters who were more conscientious provided higher ratings for older workers than for younger workers on task performance and organizational citizenship behaviours. Specifically, we tested the model of mediated moderation, in which the relation between rater conscientiousness and ratee age predicts ratee-perceived conscientiousness, which in turn predicts performance ratings. The model was significant for older ratees, but not for younger ratees. We discuss our results in terms of the “similar to me” effects and implications for organizational practices.     

Affect Intensity and Risk Preference in Life-Saving Decisions

The current studies investigated the influence of affect intensity on risk preference in life-saving decisions. Results from 4 experiments found that people are more risk-seeking when affect intensity is higher. This effect occurs in both gain and loss framing conditions (Study 2 and Study 3) and is robust in both between-subject design (Studies 1–3) and within-subject design (Study 4). The effect holds for saving human lives (Study 1 and Study 4), as well as for saving animal lives (Study 2 and Study 3). The results generalize from laboratory hypothetical settings (Studies 1–3) to simulations of a fire emergency (Study 4). Finally, the results from American samples (Studies 1–3) are replicated using a Chinese sample (Study 4). In addition, Study 5 demonstrates that the manipulations used in these experiments have an effect on affect intensity while not influencing alternative explanatory variables. The effect size for risk preference rises and falls with the effect size for manipulations.     

材料模式与认知负荷对小学生类比学习的影响

探讨学习材料不同模式和学习过程不同的认知负荷对小学生类比推理学习迁移的影响.包括两个分实验.实验1探讨学习材料的不同组织模式对小学生类比推理学习迁移的影响,两组小学生分别学习模式化与非模式化的材料,然后完成迁移程度远近不同的四类测题.结果表明,非模式化条件下完成远迁移题目的成绩显著优于模式化条件下的成绩.实验2探讨小学生在不同认知负荷条件下类比推理学习的迁移效果,两组小学生分别在高认知负荷与低认知负荷情况下学习类比推理的材料,然后完成上述四类测题.结果表明,高认知负荷条件下完成远迁移题目的成绩显著优于低认知负荷条件下的成绩.本实验结果表明,对于小学生类比推理的学习来说,非模式化、高负荷的学习更有利于促进迁移,支持了积极反应理论.     

Small-angle X-ray scattering study on the fractal structure of solid products of bituminous coal at different carbonization temperatures

Carbonization is one of the main methods for comprehensive utilization of bituminous coal. Bituminous coal and its solid products from carbonization, namely char and coke, have complex pore structures, which can be characterized by fractals. We performed a study on the fractal structure of the solid products prepared from the bituminous coal of Shuiyu mine in Shanxi Province, China, at different carbonization temperatures (25°C～1000°C) by synchrotron radiation small-angle X-ray scattering (SAXS). The results show that the bituminous coal has a surface fractal structure during the whole carbonization process. The variation of fractal dimension with carbonization temperature illustrates the different stages of the carbonization process.     

What is beautiful brings out what is good in you: The effect of facial attractiveness on individuals' honesty

This study tested whether the presence of an attractive face would influence individuals' honesty. In 2 experiments, 225 participants were asked to predict the outcome of computerised coin‐flips and to self‐report the accuracy of their predictions. Self‐reports were made in the presence of a facial photo of a female who had been rated before the experiment as high attractive, middle attractive or low attractive by other volunteers. Participants were rewarded based on their self‐reported (not actual) accuracy. The results showed that subjects tended to give more dishonest self‐reports when presented with middle or low attractive facial images than when presented with high attractive images, with self‐reported accuracy being significantly higher than the random level. The results of this study show that presented with an attractive face, subjects tend to engage in behaviours that conform to moral codes.     

心脏移植的理性审视--浅谈哲学思想对于临床工作的重要性

心脏移植实现了人类长期以来渴望生命再生的梦想,并成为一种治疗终末期心脏病的有效方法.心脏移植的发展史、心脏移植术式的选择、抗排斥和抗感染相互关系的处理、抗排斥方案的制定以及对异种心脏移植的探索等各个方面无不体现哲学辩证法的光辉.为了造福更多的终末期心脏病患者,要理性地审视心脏移植有关问题.     

文本阅读中概念提取的研究进展

文章对文本阅读中概念提取的研究进行了系统的介绍,虽然研究者得出了不同的结论,但都力图揭示文本阅读中概念提取的信息加工机制。文章在此基础上对影响文本阅读中概念提取的因素进行初步分析．发现文本类型、文本中心确定方式和抑制是主要因素。其中,文本中心确定方式是最主要的影响因素。     

角色目标对空间维度非线索更新的影响

采用实时窗口阅读技术,探讨文本阅读中角色目标在情境模型空间维度非线索更新中的作用。实验一结果表明,阅读中。如果文本叙述中的角色在一个目标指引下展开活动．那么可以促进相应空间设置内的物体的更新。实验二考察了不同性质的角色目标在空问信息加工中的作用,结果发现,相对于已经达成的目标,未达成的目标对情境模型空间维度非线索更新的影响更大。     

知识表征的新观点--知觉符号理论

在认知科学中一个经典的争论是知识在人的头脑中是如何表征的。其中占主流的理论一直是命题符号理论,而最近Barsalou又提出了一种新的观点——知觉符号理论。本文对这一新理论做了介绍,阐述了它的主要特征,比较了它与命题符号理论的差异,并提供了现今对这一理论的实验证实。希望借此能启发国内的研究者也来关注和研究这一理论。     

视角在时间语言理解中的影响

语言学家在英语的时间语言表达中发现了隐含其中的两种不同运动视角：一种是从过去指向将来的自我运动（自我运动视角moving-ego）;另一种是从将来指向过去的时间运动（时间运动视角moving-time）。心理学家McGlone＆Harding报告了在英语中视角对时问语言理解的作用,并提出人们存在MT视角的偏向。本文报告了两个实验,实验1直接运用和修改McGlone＆Harding的范式在汉语文本探讨视角对时间语言理解的影响。实验2运用信号检测理论来验证了人们存在MT视角偏向。
