Influence of the large–small split effect on strategy choice in complex subtraction

Two main theories have been used to explain the arithmetic split effect: decision‐making process theory and strategy choice theory. Using the inequality paradigm, previous studies have confirmed that individuals tend to adopt a plausibility‐checking strategy and a whole‐calculation strategy to solve large and small split problems in complex addition arithmetic, respectively. This supports strategy choice theory, but it is unknown whether this theory also explains performance in solving different split problems in complex subtraction arithmetic. This study used small, intermediate and large split sizes, with each split condition being further divided into problems requiring and not requiring borrowing. The reaction times (RTs) for large and intermediate splits were significantly shorter than those for small splits, while accuracy was significantly higher for large and middle splits than for small splits, reflecting no speed–accuracy trade‐off. Further, RTs and accuracy differed significantly between the borrow and no‐borrow conditions only for small splits. This study indicates that strategy choice theory is suitable to explain the split effect in complex subtraction arithmetic. That is, individuals tend to choose the plausibility‐checking strategy or the whole‐calculation strategy according to the split size.     

利他行为的内隐启动研究

通过视觉与组词任务启动范式的两个实验考察了利他人物形象与利他词语对利他行为的内隐启动效应。结果发现,完成利他人物形象视觉启动(实验1)与完成利他组词任务启动(实验2)的实验组被试,在独裁者分配任务中分配给他人的钱数显著多于控制组被试。研究结果表明:利他人物形象视觉和利他语义组词都可以使个体的利他行为被显著直接无意识启动,即内隐启动。研究对设计能更好地启动人们的利他行为的一般情境有重要的启示。

结节性甲状腺肿手术路径质量管理成效研究

本文通过对比分析临床路径实施前后各项质量相关指标,研究临床路径模式在精细分科部门中结节性甲状腺肿手术患者质量管理的应用成效。结果显示临床路径在质量管理过程中取得显著成效,尤其是在缩短平均住院日方面,但对于费用的控制还有待进一步提高,因此应对实施中的临床路径进行不断地持续改进,为患者提供更优质的服务。     

汉语转折复句的命题表征项目互换效应研究

采用句子一图画验证任务(sentence-picture verification task)探讨了汉语转折复句的命题表征项目互换效应。结果表明,汉语倒装转折复句的项目表达顺序为“(但是)B→虽然A”,命题表征中项目存在着互换的倾向,所形成的命题表征为“虽然A→但是B”。本研究结果初步表明,读者理解汉语转折复句可能是一个按照“虽然A(事实让步)→但是B(转折)”固定方向进行系列认知加工的过程。     

Imagery and rehearsal as study strategies for written or orally presented passages

In the present research, we studied the influence of text presentation modality on recall under imagery, rehearsal, and no strategy instructions. It was hypothesized that imagery is a more effective recall strategy for an oral presentation and rehearsal for a written presentation, and that imagery and rehearsal are effective study strategies. One hundred twenty participants participated, 80 of whom were trained in the use of imagery or rehearsal in the study of passages and 40 of whom made up the control group. A text was presented orally or in writing; the trained participants were to memorize it using the strategy taught, and the participants in the control group were to memorize it using a freely chosen strategy. They were then asked for free written recall. The results confirmed that the participants using imagery recalled the oral presentation better than the written one, and those using rehearsal recalled the written presentation better than the oral one. The discussion focuses on a selective-interference explanation of the presentation modality effects. Practical suggestions are given, and implications for future research are discussed.

审美现代性与日常生活批判

一、问题的提出从历史角度说 ,艺术作为人类文化一个不可或缺的重要组成部分 ,是与社会生活密不可分地联系在一起的。审美发生学的研究已经证实 ,艺术的基本社会功能就是协同功能 ,通过艺术活动来教化社会成员 ,协调社会关系 ,传递文化、道德和行为方式 ,沟通社会成员之间的情感联系。这种功能我们可以在原始艺术、古典艺术甚至一切前现代艺术中清楚地看到。在前现代 ,艺术与社会的功能关系基本上是协调一致的。虽然在传统文化中不乏反抗现存社会的艺术 ,特别是面临巨大变迁的时代的艺术 ,但从总体上说 ,艺术和社会成员的日常生活及其意识形…     

概念及概念结构研究新进展

近来有关归类和概念结构的研究与理论出现了两个方面的转变。第一个方面是从概念定义属性的假设 (经典观 )到概念表征属性的观点 (概率观 ) ;第二个方面是从概念以相似性组织的观点到概念围绕理论而组织的观点。本文综合概述了基于相似性和理论驱动的归类理论。
