学科领域知识丰富性对中学代数问题表征层次的影响

研究学科领域知识丰富性不同的学生在问题表征过程中信息表征层次的特点。采用“学习-再认”范式,以5类等式为材料,62名初二学生参与实验。结果：两组被试对表面和原理特征一致的等式产生明显的错误再认;对表面特征不一致等式的错误率明显减少。无论原理特征是否一致,两组对表面特征一致等式的反应时无显著差别,但在正确率上丰富组的更高。说明,两组均以有序的系列加工方式编码信息,优先编码表面特征。贫乏组对原理特征的编码干扰表面特征的加工,因而原理特征被丢弃。丰富组加工表面特征则无干扰现象出现,两种特征均能作为再认线索。     

多元视角下的城邦与灵魂——记第九届柏拉图研讨会

2010年8月2日-7日在日本东京庆应义塾大学山田校区举办的第九届柏拉图研讨会以"柏拉图的<理想国>"(Plato's Politeia)为题,汇聚数百名当代学者,全方位地检视这部巨著中对城邦、灵魂、善、形式(理念)、诗歌等诸多主题的反思.本文略记大会盛况及日本古典学界观感.     

社会主义核心价值体系培育的两个向度

社会主义核心价值体系重在培育。社会主义核心价值体系的培育与其本身的内在品质、何以可能密切相关。提高自身的合法性与魅力,是社会主义核心价值体系培育的前提基础和内在要求。增强社会主义核心价值体系的合法性与魅力,从理论品质维度来看,就要使其客观全面反映马克思主义理论精髓,保持其真理性、彻底性、完备性、自洽性与先进性;从实践要求维度来看,就要提高其对社会需要的满足度,保持其实践性、先进性、人民性、批判性、开放性与创新性。     

客体及其位置记忆的眼动研究(中文)

In this paper we briefly describe preliminary data from two experiments that we have carried out to investigate the relationship between visual encoding and memory for objects and their locations within scenes. In these experiments, we recorded participants′ eye movements as they viewed a photograph of a cubicle with 12 objects positioned pseudo-randomly on a desk and shelves. After viewing the photograph, participants were taken to the actual cubicle where they undertook two memory tests. Participants were asked to identify the 12 target objects(from the photograph)presented amongst 12 distractors. They were then required to place each of the objects in the location that they occupied in the photograph. These tests assessed participants′ memory for identity of the objects and their locations. In Experiment 1, we assessed the influence of the encoding period and the test delay on object identity and location memory. In Experiment 2 we manipulated scanning behaviour during encoding by "boxing"some of the objects in the photo. We showed that using boxes to change eye movement behaviour during encoding directly affected the nature of memory for the scene. The results of these studies indicate a fundamental relationship between visual encoding and memory for objects and their locations. We explain our findings in terms of the Visual Memory Model(Hollingworth & Henderson, 2002).     

泰文和中文阅读过程中的眼动控制(中文)

This paper analyses some aspects of the eye movement behaviour of readers of Thai and Chinese. The main focus is on readers′landing site distributions on words and how these are affected by the lack of clear word boundary information due to the absence of inter-word spaces. Empirical evidence from Thai and Chinese readers suggest that readers can relatively accurately target word centres. We make the case that this accuracy can be accounted for by a default targetting model(effectively, the prior landing site distribution, in Bayesian terms)modulated by statistical cues about word beginnings available from word-initial character frequencies.     

语言期望概率、不确定性输入及其对阅读的眼动研究启示(中文)

One nearly ubiquitous assumption in models of linguistic comprehension and of eye movement control in reading alike is of partial modularization between word-level and sentence-level processing: that the outcome of word recognition, and thus the input to sentence-level comprehension, is a categorial representation. Yet such a partial modularization throws away residual uncertainty regarding word identity that might potentially be of value to the comprehender further downstream in the sentence. Here I describe a line of research combining computational modeling with experimental eye-tracking work to explore the consequences of removing this partial modularity assumption.

也谈"一画论"之"法"论——与叶朗先生商榷

石涛《画语录》思维高妙,关于一画的内涵,自20世纪40年代起我国学术界就争议不断。笔者认为一画论就是绘画之法,这个法是有与无的统一。整部《画语录》有九个章节明确谈具体的绘画技法,通篇又贯穿着无法的精神。宇宙是乾旋坤转的,我是独立唯一的,一画之法必为活法。石涛是着眼于活法性质来界定一画内涵的。整部《画语录》闪耀着不断创新、强调变化的艺术辩证法光辉。
