A review of the worst performance rule: Evidence, theory, and alternative hypotheses

This paper reviews evidence, theory, and alternative hypotheses for the worst performance rule (WPR), which states that on multitrial cognitive tasks, worst performance trials predict general intelligence (g) better than best performance trials. A review of the relevant evidence indicates that the WPR has been found for a variety of participants, tasks, and measures. A review of relevant theories reveals that the WPR appears to be related to cognitive factors (e.g., lapses in working memory) as well as biological factors (e.g., individual differences in neural oscillations). A review of alternative hypotheses shows that the WPR cannot be attributed to statistical or data artifacts such as outliers, unreliable measurement, or variance compression. The preponderance of evidence supports the hypothesis that the WPR holds for cognitive tasks high in g saturation but not for cognitive tasks low in g saturation. The paper ends with a call for research on the causes of the WPR and for research on the correlates of best performance.

从风险决策中的多次博弈到单次博弈：量变还是质变?

诺贝尔经济学奖获得者Samuelson于1963年发现人们在单次和多次博弈条件下决策行为不一致。文章综述了两种博弈条件下人们决策行为的差异并质疑了这种差异的传统理论解释机制。描述或预测决策行为的风险决策理论其实只采用了一种评价法则—— 期望法则, 始终没有跳出“最大化”的窠臼。基于实验证据, 我们推测, 多次博弈时人们遵守了期望法则, 而单次博弈时人们所遵循的是非补偿性法则。从多次博弈到单次博弈, 不单单是一种博弈次数上的变化(量变), 而是代表了从期望法则(补偿性法则)到非补偿性法则两种策略之间的转变(质变)。最后, 文章介绍了单次、多次博弈问题在医疗、应急管理以及投资领域的体现, 并呼吁更多的研究者关注单次、多次博弈问题。     

Moral Relativism and Majority Rule

A number of arguments against relativism are based on the concept of majority rule. Since, the arguments allege, on relativism moral truth is founded on majority opinion, relativism entails that (a) moral progress and reform are impossible, (b) propaganda, advertising, brainwashing, and high birth rates turn mistaken moral judgments into correct ones, (c) moral horrors, if enough people believe them acceptable, are not moral horrors at all, (d) finding out what’s right and what’s wrong is extremely easy, (e) moral reasoning is very different from what we normally take it to be, and (f) internal criticism of a moral code is impossible. These arguments get their due in this article, which first defines and explicates relativism and then exposes, explains, and criticizes the arguments. Especially important to understand about the relation between relativism and majority opinion is the notion of a convention. Accordingly, it is discussed at some length.     

先秦法家法治思想的衍变——以《管子》、《商君书》和《韩非子》为中心

中国的“法治”思想源远流长,始于先秦法家,从春秋时期的管仲提出“以法治国”的主张,到战国时期的商鞅治国重“法”,再到韩非“法术势”相结合的法治理论的构建,先秦法家的法治思想经历了一个从萌芽到发展再到成熟的衍变过程,但法家的法治思想始终没有脱出君主专制下“以法治国”的巢臼。     

直言推理系统

本文构造了直言推理的一个系统MA,内容包括直接推理和三段论,但未考虑单称命题。此系统实际上是名辞逻辑系统MZ的子系统,精确地说是关于类名及其否定和由它们形成的本辞的系统。文中证明了系统MA的可靠性和完全性,并提出了它的自然推理系统。     

医药代表问题及其法律规制

近年我国医药行业不断发展,其营销人员的数量也在膨胀,从而引发了药品购销中的一系列问题,而医药代表在其中扮演着重要角色。由此,“医药代表问题”已引起人们的反感;国家和医院也采取不少措施打击,但收效甚微。医药代表问题成为社会热点。分析医药代表问题的社会成因,提出法律规制,旨在促进这一行业健康发展。     

小学四、五年级数学诊断性测验的编制——基于规则空间模型的方法

基于规则空间模型, 以小学四、五年级数学诊断性测验的编制为例, 探索了认知诊断理论背景下诊断性测验的编制方法。研究发现, 基于规则空间模型编制的诊断性测验具备优良的信效度, 尤其在结构效度上具有突出优势。应用该测验对1059名四、五年级学生进行诊断测验的结果显示:在整体上, 学生对整数、初级运算与应用掌握得较为巩固, 对量、统计、规律、高级运算掌握较差;在发展趋势上, 量、统计、规律、高级运算是四、五年级之间进步最快的属性。
