Learning to avoid spiders: fear predicts performance,not competence

We used an immersive virtual environment to examine avoidance learning in spider-fearful participants. In 3 experiments, participants were asked to repeatedly lift one of 3 virtual boxes, under which either a toy car or a spider appeared and then approached the participant. Participants were not told that the probability of encountering a spider differed across boxes. When the difference was large (Exps. 1 and 2), spider-fearfuls learned to avoid spiders by lifting the few-spiders-box more often and the many-spiders-box less often than non-fearful controls did. However, they hardly managed to do so when the probability differences were small (Exp. 3), and they did not escape from threat more quickly (Exp. 2). In contrast to the observed performance differences, spider-fearfuls and non-fearfuls showed equal competence, that is comparable post-experimental knowledge about the probability to encounter spiders under the 3 boxes. The limitations and implications of the present study are discussed.     

学前儿童执行功能与问题行为的关系:情境和性别的特异性

运用追踪设计检验了学前儿童执行功能特定成分和问题行为跨情境和性别的关系。选取101名学前儿童（48名男孩）为研究对象,采用实验任务测量儿童的执行功能,一年后采用母亲和教师报告分别收集儿童在家庭和学校情境的问题行为。结果发现,控制儿童年龄后：（1）在男孩中,抑制控制、认知灵活性和工作记忆负向预测一年后家庭情境的外化问题,认知灵活性负向预测一年后学校情境的外化问题,抑制控制正向预测一年后学校情境的内化问题;（2）在女孩中,执行功能三个成分均不能显著预测家庭情境的问题行为,认知灵活性正向预测一年后学校情境的外化问题。执行功能三个成分与问题行为间存在不同效应模式,且存在跨情境和性别的特异性。

博弈中的反社会惩罚

博弈中的反社会惩罚是指博弈者对表现出亲社会行为的高贡献或高合作性他人实施有代价经济惩罚、消极评价或排斥打压的现象。已有研究用带惩罚的经典博弈范式证明了反社会惩罚受到多种个体与环境因素的影响, 并分别从侵犯、报复、社会比较、偏离群体规范、进化策略视角提出了解释其产生机制的5种假说。未来研究可在进一步厘清概念与测量指标、创新研究方法、拓展影响因素研究、明确产生机制、开展针对性干预研究方面做深入探索。

孕12周～14周血小板计数及平均血小板体积对子痫前期的预测作用

探讨孕12周～14周血小板计数(PLT)及平均血小板体积(MPV)对子痫前期的预测作用.选取50例子痫前期患者为病例组,234正常孕妇为对照组,采用非参数检验方法(K-S检验)进行病例对照研究,比较童组研究对象孕12周～14周PLT及MPV的差异,寻找孕早期对子痫前期可以起到预测作用的血清学标志物.病例组和对照组的PLT及MPV均无显著性意义(P＞0.05).孕12周～14周PLT及MPV对子痫前期无预测作用.     

Setting the Record Straight: Confucius’ Notion of Ren

Comparative studies involving early Confucian ethics often appear to assume that it is a unified approach to morality. This essay challenges that assumption by arguing that Confucius had a significantly different conception of ren, commonly viewed as central to Confucian ethics, from that of Mencius. It is generally accepted that ren has two senses: in a narrow sense, it is the virtue of benevolence (or compassion); in a broad sense, it is the all-encompassing ethical ideal. Both senses fail to capture Confucius’ conception of ren, for the narrow sense fits only Mencius’ understanding of ren, while the broad sense lacks emphasis and precision. I propose a third sense of ren, that is, ren as an integral, higher-order virtue with respect as its most salient component. This sense of ren is more in keeping with the textual evidence in the Analects. It played a key role in Confucius’ political-moral thinking and made his doctrine diverge considerably from that of Mencius, who understood ren primarily as compassion.

Unusual stress behaviour of CeO2-doped diamond-like carbon nanofilms

CeO₂-doped diamond-like carbon (DLC) films with thicknesses of 180–200 nm were deposited by unbalanced magnetron sputtering. When the CeO₂ concentration is in the range 5–8%, the residual compressive stress of the deposited films is reduced by 90%, e.g. from about 4.1 GPa to 0.5 GPa, whereas their adhesion strength increases. These effects are attributed to the dissolution of CeO₂ within the DLC amorphous matrix and a widening interface between the DLC film and the Si substrate, respectively.
