分散空间注意条件下客体特征一致性对视觉特征错觉性结合的影响

本研究通过设置对空间注意资源的分配实施强行操作的情形下,探讨了主、次作业客体形状一致性和次作业客体间距对乏空间注意区次作业客体颜色、形状特征的检测及对特征错觉性结合的影响。实验结果表明：（１）分散空间注意使次作业区域注意减弱,对客体及其颜色和形状特征的识别均产生明显影响．而且对形状的影响又大于颜色;（２）特征错觉性结合率,主、次作业客体形状一致时比客体形状不一致时明显增大;（３）次作业客体间距对特征错觉性结合率无明显影响,但客体形状一致性和客体间距之间存在明显交互作用．     

Coping with Abusive Supervision: the Neutralizing Effects of Perceived Organizational Support and Political Skill on Employees’ Burnout

While research into the antecedents of burnout has steadily grown, the relationship between abusive supervision and burnout remains largely unknown. In addition, we know little about the contingencies under which abusive supervision may be related to employees’ burnout. This study aims to examine the contingency side of the abusive supervision-burnout relationship by addressing the exploratory question of whether perceived organizational support and individual differences in political skill play moderating roles in the abusive supervision-burnout relationship. The present article developed a model and tested it with data from a sample of 248 supervisor–subordinate dyads. We hypothesized and found that (1) Abusive supervision was positively associated with burnout; (2) the positive relationship between abusive supervision and burnout was moderated by the employees’ perceived organizational support in such a way that the relationship was weaker for employees who perceive higher rather than lower organizational support; (3) the positive relationship between abusive supervision and burnout was moderated by the employees’ political skill in such a way that the relationship was weaker for people with high, rather than lower level of political skill.     

Nodule Detection with Eye Movements

Radiologists often miss nodules that may represent lung cancer on chest radiographs. We investigated whether eye movements collected during the search for lung nodules by large samples of laypeople may provide information that could assist radiologists in their detection. For that purpose, we developed a partially invisible Markov model with partially unobserved states and analyzed eye tracking data of over 100 laypeople who reviewed 14 chest X‐ray images, of which seven contained a potentially cancerous nodule. We used the luminance value of the pixels in the X‐ray images as prior information on the possible location of a nodule and identified six regions of interest on each image that may contain a nodule. Our study demonstrated that the eye movements recorded from laypersons contained information that may assist radiologists in the detection of nodules in chest X‐rays, which has important implications for crowdsourcing of search for pulmonary nodules, which are discussed.

Differences in the micromechanical properties of dendrites and interdendritic regions in superalloys

Statistical analysis of white-light interferometry (WLI) experiments performed on Ni-based single-crystal superalloys (SX) have revealed a different height distribution between the dendritic cores (DCs) and the interdendritic regions (IRs) of the polished samples. The micromechanical property difference is largely ascribed to the uneven distribution of the alloying elements. In this context, possible reasons for this difference are discussed by comparing with different experiment results obtained by previous researchers, and a proposal forecasting the hardness ratio of IRs/DCs is put forward.     

Internet Addiction and Well-Being: Daoist and Stoic Reflections

This article explores the phenomenon of Internet addiction and its possible amelioration, from both Eastern and Western philosophical perspectives. Internet addiction is caused by the excessive use of the Internet and its resulting dependence, having negative effects on human well-being. The ideas of a key ancient Chinese Daoist thinker Zhuangzi 莊子 and his Western contemporaries, the Stoics, as viewed through the world, the things and beings in it, and their relationships, offer insights which may be used to alleviate these effects. The application of and comparison between the two ancient philosophies in addressing the issue of Internet addiction can give us inspiration to confront the challenges of technological enslavement in general and Internet addiction in particular. This is no doubt a help in our pursuit of well-being.

结构因素对阅读保持影响的研究

本研究探讨文章阅读过程中结构因素对文章信息保持的影响作用。包括两个实验。实验 1探讨阅读文章结构是否清晰及主体对文章结构是否有清晰的把握对文章信息保持的影响效果。结果表明 ,阅读的文章结构越清晰 ,主体对文章结构把握能力越强 ,越能促进文章的信息保持。实验 2进一步探讨文章的结构清晰及主体对文章结构的清晰把握促进的是何种信息的保持。结果证明 ,结构清晰与否促进的是文章的主要信息的保持 ,而对文章的细节性信息促进作用不大。本研究结果表明 ,文章的结构因素对阅读保持有促进作用 ,主要是促进文章的主要信息的保持。     

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.

解读“反胜为败”的现象：一个“Choking”过程理论

运动员关键时刻以先赢后输的形式丢掉冠军的现象越来越多地发生在现代竞技体育比赛中。心理学上称之为压力下的“Choking”,并定义为压力条件下一种习惯的运动执行过程发生衰变的现象。对于“Choking”的研究开始于八十年代初中期,迄今为止,主要有干扰假说和自动执行假说解释其发生机制。但由于现有的假说过于简单,理论的研究一直不能为实践防治“Choking”提供可行的措施。本文基于笔者多年来的研究积累,就这一空缺,提出并讨论了一个“Choking”过程理论。该理论把“Choking”作为一个过程来讨论,包括引起因素、认知过程、应付过程和运动过程。根据过程理论,本文讨论了“Choking”发生机制。在此基础上,提供了防止“Choking”发生的具体可行性措施。
