Continuous and discontinuous drawing: high temporal variability exists only in discontinuous circling in young children

The authors studied whether the drawing variability in young children is best explicable by (a) demands on the explicit timing system, (b) an underdeveloped ability to control limb dynamics, or (c) both. The explicit timing demands were lower in continuous drawing in comparison with the discontinuous task. The authors manipulated limb dynamics by changing the number of joints involved, with line drawing requiring fewer joints than circle drawing. Results showed that young children had high temporal variability in discontinuous circling but not in other conditions. The authors argue that both explicit timing and dynamic complexity of limb control may be determinants of temporal consistency and may thus play an important role in the development of drawing and writing skills in children.     

位置和内容对网页广告效果影响的眼动评估

使用TobiiT120型眼动仪,以16名大学生为被试,记录他们阅读嵌有网页广告新闻网页时的眼动注视过程,以探讨广告呈现位置、新闻内容与网页广告的相关性是否影响人们对网页广告的注视。实验采用3（广告位置：上方、中间、下方）×2（相关性：相关、不相关）两因素被试内设计。结果发现：（1）新闻内容和网页广告的相关性不影响人们对网页广告的加工;（2）对位于新闻上方和新闻中间的网页广告,被试的注视次数较多,且注视时间较长;（3）对位于新闻中间的网页广告,其再认效果优于位于新闻上方和新闻下方的广告。表明只有网页广告呈现位置这一因素影响被试对网页广告的注视。     

欧洲近现代民主法治型社会治理模式与规范伦理

本文深入分析了欧洲近现代民主法治型社会治理模式与规范伦理的具体成因、基本特征和主要内容,并对二者的内在关联性进行了说明.笔者认为,麦金太尔在重建传统生活共同体基础上恢复古希腊美德伦理的主张只是一种道德乌托邦幻想,我们应当在努力完善民主法治型社会治理模式和规范伦理类型的前提下,继续推进启蒙运动所开创的现代性事业,而不是一味地吁求回归传统.     

The “Obama Effect”: How a salient role model reduces race-based performance differences

Barack Obama, the first Black-American president, has been widely heralded as a role model for Black-Americans because he inspires hope. The current study was conducted to assess whether, beyond simply inspiring hope, this “Obama Effect” has a concrete positive influence on Black-Americans’ academic performance. Over a three-month period we administered a verbal exam to four separate groups of Black- and White-American participants at four predetermined times. When Obama’s stereotype-defying accomplishments garnered national attention - just after his convention speech, and election to the presidency - they had a profound beneficial effect on Black-Americans’ exam performance, such that the negative effects of stereotype threat were dramatically reduced. This effect occurred even when concerns about racial stereotypes continued to exist. The fact that we found performance effects with a random sample of American participants, far removed from any direct contact with Obama, attests to the powerful impact of ingroup role models.     

伏隔核和中脑腹侧被盖区内食欲素在吗啡奖赏中的作用

实验采用条件性位置偏爱（CPP）模型考察中脑腹侧被盖区（VTA）和伏隔核壳区（NAcSh）内食欲素（orexin）在吗啡奖赏中的作用。Wistar大鼠分为盐水训练组和吗啡训练组。3轮吗啡（或盐水）匹配训练前,双侧VTA或NAcSh内给予OXR1拮抗剂SB334867（VTA: 0, 1, 5μg;NAcSh: 0, 1, 3μg）;或2轮吗啡（或盐水）匹配训练前NAcSh内给予orexin A（0, 2, 4, 6μg）,观察其对吗啡CPP建立的影响。结果表明,VTA内给予SB334867抑制吗啡CPP建立,并存在剂量效应关系;NAcSh内给予SB334867或orexin A均未影响吗啡CPP建立,而orexin A可增加吗啡处理大鼠的运动性。以上结果表明,VTA和NAcSh内的orexin在吗啡奖赏中扮演的角色不同,可能调控成瘾行为的不同成分     

大学生人格评定的和谐追求——200个人格词汇喜好度中美对比研究

本研究选取Anderson1968年研究中的200个核心人格特质词汇,请165名在校大学生对词汇进行喜好度评定.对比Anderson(1968)的研究结果,发现:1)中西方被试均将真诚评定为最受欢迎的个性品质;2)中国被试作答较少出现极端值;3)中国被试评出的前10位积极品质均与人际和谐有关;而西方被试评出的前10位积极品质主要涉及诚信和个人能力两方面;4)中西方被试评出的前10位消极词汇均为他相关词汇,并和积极词汇相对应.     

道德与自然:"形上之道"与"形而上学"的本质区别

Both thinkings on Dao in Chinese philosophy and metaphysics in Western philosophy investigate things on a spiritual level that transcends experience, but there are incommensurable differences between them. The objective of “metaphysics” is ontological knowledge about nature from the perspective of epistemological “truth-pursuing”. Western metaphysics is thus a “metaphysics of nature”. Dao in Chinese philosophy, on the other hand, more often manifests itself in “good-pursuing” by means of the internal, experiential pursuit of moral stature and spiritual security. Philosophy of Dao is thus a “metaphysics of ethics”. The cause of this difference can be traced back to the differences between the rational tradition of the West, characterized by the dualism of the subject and the object, and the moral tradition of China, characterized by the integration of man and nature. __________ Translated by Zhang Lin from Lunlixue yanjiu 伦理学研究 (Studies in Ethics), 2007, (4): 62–65     

抑郁症患者的自传体记忆特征及其应用自传体记忆测验的元分析

研究目的在于探讨抑郁症患者自传体记忆的特征以及自传体记忆测验(the autobiographical memory test, AMT)在该领域的应用情况。通过文献检索, 搜集了18篇应用AMT作为测评工具的抑郁症自传体记忆研究, 抑郁症患者566人, 正常对照组457人。元分析研究发现, 和正常对照组比较, 抑郁症组的具体性记忆减少, 概括化记忆增多, 反应迟缓。目前对这种现象的解释主要有功能性回避模型、认知执行受损模型和沉思模型; 年龄、抑郁情绪以及AMT测试程序对测试结果有明显影响; 发表偏倚和敏感性分析显示存在发表偏倚, 但稳定性较好。AMT在抑郁症研究存在灵敏度不足等局限, 作者从AMT程序、研究设计等方面提出了改善建议。     

趋化因子10与临床疾病关系的研究进展

趋化因子10（CXCL10）是由干扰素诱导产生,过去又把它称为干扰素-γ诱导蛋白10（IFN—γIndueible protein 10）。其具有强大的招募中性粒细胞、促进多种细胞因子分泌及抑制部分肿瘤生长等多种生物学作用。在慢性炎症、过敏性炎症、自身免疫性疾病、移植物排斥反应和肿瘤等多种疾病的病理过程中起重要作用。
