连续和同时线索化条件下的返回抑制容量

利用线索-靶子模式进行了返回抑制容量的两个实验。实验一对外周数个位置连续线索化,实验二对外周数个位置同时线索化。结果表明：(1)在连续线索化条件下,当线索化位置是相邻时,返回抑制容量可以达到4个,当线索化位置是间隔时,返回抑制容量只有1个。(2)在同时线索化条件下．当线索化位置是相邻时,返回抑制容量可以达到3个,当线索化位置是间隔时．返回抑制容量只有1个。结果支持认为存在着两种不同的返回抑制的观点,即一种是弥散性的,其容量较大;另一种是集中性的,其容量只有一个。     

特殊儿童个案研究资料收集的方法

本文介绍了特殊儿童个案研究中资料收集的三种重要方法：观察法、访谈法和档案资料法。本文较详细地介绍了各种方法的定义、性质,包含的不同类型,不同角色的研究者与被试之间的关系,以及怎样合理利用不同方法获得的资料等。这三种方法各有自己的优点和缺点,为保证研究资料的多样性和有效性,在个案研究中常常是联合运用的。     

The cognitive underpinnings of emerging mathematical skills: Executive functioning,patterns, numeracy,and arithmetic

Background: Exposure to mathematical pattern tasks is often deemed important for developing children's algebraic thinking skills. Yet, there is a dearth of evidence on the cognitive underpinnings of pattern tasks and how early competencies on these tasks are related to later development. Aims: We examined the domain‐specific and domain‐general determinants of performances on pattern tasks by using (a) a standardized test of numerical and arithmetic proficiency and (b) measures of executive functioning, respectively. Sample: Participants were 163 6‐year‐olds enrolled in primary schools that typically serve families from low to middle socioeconomic backgrounds. Method: Children were administered a battery of executive functioning (inhibitory, switching, updating), numerical and arithmetic proficiency (the Numerical Operations task from the Wechsler Individual Achievement Test‐II), and three types of pattern tasks. Results: Contrary to findings from the adult literature, we found all the executive functioning measures coalesced into two factors: updating and an inhibition/switch factor. Only the updating factor predicted performances on the pattern tasks. Although performance on the pattern tasks were correlated with numerical and arithmetic proficiency, findings from structural equation modelling showed that there were no direct or independent relationships between them. Conclusions: The findings suggest that the bivariate relationships between pattern, numeracy, and arithmetic tasks are likely due to their shared demands on updating resources. Unlike older children, these findings suggest that for 6‐year‐olds, better numerical and arithmetic proficiency, without accompanying advantages in updating capacities, will no more likely lead to better performance on the pattern tasks.     

受试者知情同意决策与家庭的相关度研究

在中国大陆,至少有以下四个方面的因素影响着受试者知情同意的决策,包括研究者的告知和研究者的导向、人体研究不同分期或类型的差别、受试者个体特质的状况、受试者家庭及类家庭成员(朋友、同伴等)的观念.这些因素与家庭的相关度不尽相同,家庭在不同领域、不同类型、不同层级的人体研究中参与决策表现出不同范围和深度.论证了在受试者知情同意决策过程中,需要受试者家庭或类家庭成员的参与,以实现保护受试者的目的.     

新时期中医药进退之争的前提条件

以科学、理性的态度对待当前中医药进退之争,就必须正确应用与表述争辩中出现的相关问题.认为关键性概念和名词的正确应用与表述是这场之争的前提条件,积极探索现代与传统两种医学体系关系则必须正确认识相关问题.     

眼睛注视是独特的吗?——来自发展的证据

采用改编的Posner视空间线索化任务,考查6~9岁儿童对眼睛注视、手指指向、箭头指向和代向汉字4种中央线索的注意定向。结果发现,6岁儿童已经能对眼睛注视线索进行注意定向,并随着年龄增长而改善。7岁组和8岁组儿童注意定向的成绩显著改善,7岁可能是儿童对中央线索注意定向发展的特定阶段。而对手指指向和箭头的注意定向,只有8岁和9岁儿童表现出来。对代向汉字线索的注意定向,8岁时开始出现,9岁时表现出显著的提高。结果提示,眼睛注视线索可能是一种独特的视觉线索,有别于其他中央线索引发的注意定向的发展。     

《易传》道家说质疑

本文从陈鼓应先生论证“《易传》道家说”的重点文章《〈彖传〉与老庄》、《〈彖传〉的道家思维方式》出发,不仅指出其论据方面的不足,而且指出其论证方法是使用“丐辞”、“默证”。因此,《彖传》不能成立。甚至陈先生所用的“道家”这一名目,也不适当。从而说明“《易传》道家说”不能成立,其“道家主干说”也因此缺少重要文献材料,难以服人。     

如何在社会竞争中养生

养生有广义和狭义之别:通常我们讲养生,指的是保养身体,以健康长寿为目的.但古人讲养生,其含义要广得多.首先须通过心态的调整(调心),修炼自己的禀性(修性),改变思维模式,去掉不良习气;其次必须放弃固有的观念,游于人世间而心不染著(无染),破除世俗的知见,进入超然物外的境界(扩容);最后在上述自在状态下,升起人生大智慧,道法自然善利万物(积德)而养生,自然而然地获得健康长寿(合道)的受用.     

The Contextual Character of Causal Evidence

I argue for the thesis that causal evidence is context-dependent. The same causal claim may be warranted by the same piece of evidence in one context but not another. I show this in particular for the type of causal evidence characteristic of the manipulability theory defended by Woodward (Making things happen: a theory of causal explanation. Oxford University Press, Oxford, 2003). My thesis, however, generalises to other theories—and at the end of the paper I outline the generalization to counterfactual theories. The paradigmatic form of causal evidence in the manipulability theory is provided by tests of the functional invariance of the relation between putative cause and effect under interventions (on the putative cause). I show that such evidence exhibits at least two kinds of context-relativity: personal, or epistemic; and situational, or objective.
