Varying the Explanatory Span: Scientific Explanation for Computer Simulations

This article aims to develop a new account of scientific explanation for computer simulations. To this end, two questions are answered: what is the explanatory relation for computer simulations? And what kind of epistemic gain should be expected? For several reasons tailored to the benefits and needs of computer simulations, these questions are better answered within the unificationist model of scientific explanation. Unlike previous efforts in the literature, I submit that the explanatory relation is between the simulation model and the results of the simulation. I also argue that our epistemic gain goes beyond the unificationist account, encompassing a practical dimension as well.     

1993~2013年常驻高海拔地区军人心理健康状态的横断历史研究

研究为探索常驻高海拔地区军人心理健康水平如何随社会年代变迁而改变,运用了横断历史元分析的方法,对1993年至2013年38篇采用90项症状自评量表(SCL-90)的文献调查数据进行分析,考察了11454名常驻高海拔地区军人在该量表上9个因子得分随年代变化的趋势.结果发现:(1)SCL-90的7个因子均值与年代负相关,且不受期刊类型等的影响.20年来,7个因子下降了5%~15%不等.其中,强迫变化最大,抑郁、焦虑、人际敏感、偏执和精神病性均变化明显.这说明,常驻高海拔地区军人心理健康虽有所波动但整体水平逐步提升,变化幅度大致属于中等程度.(2)当年军费占GDP比值、居民消费水平指数与SCL-90部分因子均值负相关显著;5年前的居民消费水平指数与7个因子显著负相关.这说明,国防建设的经济投入和居民消费水平可能是影响常驻高海拔地区军人心理健康水平的重要因素.     

社会公正对权威合法性的影响:社会阶层的调节作用

社会层面中的权威合法性研究是国内外学者和管理实践者近来关注的重要问题。而社会公正的两个维度——分配公正和程序公正对权威合法性的交互作用的结果并不一致。本研究基于解释水平理论,提出社会阶层能调节分配公正和程序公正对权威合法性感知的交互作用,并通过实验室研究和情境启动两种方法进行验证。结果发现对低阶层者来说,无论是否程序公正,分配公正能显著提高个体的权威合法性感知;在分配公正和多得不公条件下,程序公正显著降低权威合法性感知。对高阶层者来说,分配公正能显著提高程序公正时的权威合法性感知;程序公正能显著提高分配公正时的权威合法性感知。研究结果启示社会管理者在推行依法治国时应针对不同阶层民众的思维方式采取管理策略。     

Do we reflect while performing skillful actions? Automaticity,control, and the perils of distraction

From our everyday commuting to the gold medalist’s world-class performance, skillful actions are characterized by fine-grained, online agentive control. What is the proper explanation of such control? There are two traditional candidates: intellectualism explains skillful agentive control by reference to the agent’s propositional mental states; anti-intellectualism holds that propositional mental states or reflective processes are unnecessary since skillful action is fully accounted for by automatic coping processes. I examine the evidence for three psychological phenomena recently held to support anti-intellectualism (choking under pressure, expertise-induced amnesia, and expert confabulation) and argue that it supports neither traditional candidate, but an intermediate attention-control account, according to which the top-down, intention-directed control of attention is a necessary component of skillful action. Only this account recognizes both the role of automatic control in skilled action and the need for higher-order cognition to thread automatic processes together into a unified, skillful performance. This applies to bodily skillful action in general, from the world-class performance of experts to mundane, habitual action. The attention-control account stresses that, for intentions to play their role as top-down modulators of attention, agents must sustain the intention’s activation; hence, the need for reflecting throughout performance.     

《大智度论》的"念佛"思想研究

试析元代汉人对伊斯兰教的"解读"--以定州《重建礼拜寺记》碑为例

元代是伊斯兰教在中国大发展的时期,在中国伊斯兰教史上占有重要地位。本文以元代定州《重礼拜寺记》碑为中心,考察了元代汉人对伊斯兰教的认识与理解,指出在元代,汉人尤其是士大夫阶层业已开始以儒家思想来阐释伊斯兰教,这在中国思想史上尚属首次,在某种程度上促使伊斯兰教走上了非文化自觉意义上的调适之路。其开山之功,意义重大,不容抹煞,值得深入探讨。     

不熟练汉英双语学习者第二语言词汇和概念表征的特点

本研究采用翻译识别任务探查了不同熟练程度的汉英双语儿童的词汇和概念表征的特点。被试为从一年级开始学习英语的小学三、五年级和初中一年级儿童共50名,结果发现．各组被试在进行翻译识别时．反应错误率随着熟练程度的提高逐渐降低,且各组被试都产生了显著的正字法干扰效应和语义干扰效应。这一结果表明,不熟练的汉英双语儿童可以通过词汇联系和概念联系加工第二语言中的词。     

Perceived in‐group threat as a factor moderating the influence of in‐group norms on discrimination against foreigners

Within the framework of an intergroup relations paradigm, three studies analysed the role of in‐group threat in intergroup discrimination and the influence of in‐group norms on intergroup discrimination. The first study showed that perceived socio‐economic threat underlies Swiss nationals' prejudice and discrimination toward foreigners in Switzerland. The second and third studies experimentally tested the hypotheses, first, that variations in perception of in‐group threat will produce change in initial discrimination, and, second, that the influence of an in‐group norm (pro‐ vs. anti‐ discriminatory) is moderated by the perception of in‐group threat. In support of these predictions, results of both studies indicated that discrimination was reduced when perceived in‐group threat was low. However, the anti‐discriminatory in‐group norm reduced discrimination only when perceived in‐group threat was low. No influence was observed for the pro‐discriminatory in‐group norm.

Normative data on the familiarity and difficulty of 196 Spanish word fragments.

In this article, normative data on the familiarity and difficulty of 196 single-solution Spanish word fragments are presented. The database includes the following indices: difficulty, familiarity, frequency, number of meanings, number of letters given in the fragment, first and/or last letters given, and ratio of letters to blanks. A factor analysis was performed on difficulty, and two factors were obtained. Frequency, familiarity, and number of meanings loaded highly on the first factor, which we consider to measure lexical processes, whereas number of letters in the fragment, first and/or last letters given, and ratio of letters to blanks loaded highly on the second factor, which we judge to be determined by perceptual information. Regression analyses using factor scores as predictors showed that both factors accounted for a significant part of the completion probability scores. The full set of these norms may be downloaded from the Psychonomic Society Web archive at www.psychonomic.org/archive/.
