Visual working memory for trained and novel polygons

This study investigates whether training changes the capacity of visual working memory (VWM). We compared change detection performance for novel and trained polygons. During training, subjects developed familiarity with 8 random polygons. Specifically, 4 polygons from a set of 8 were presented on each trial. After a brief retention interval, one of the polygons changed and subjects judged which one had changed (Exps. 1–2) or whether there was a change (Exp. 3). After 320 training trials, subjects could recognize the trained polygons with high accuracy. In the testing phase, subjects carried out the same task again, only this time each trial might contain all familiar polygons, all novel polygons, or a mixture of familiar and novel polygons. We found that change detection performance improved during training, but the improvement was not limited to trained polygons. We suggest that familiarity of non-nameable shapes plays a limited role in modulating the capacity of VWM.     

小学儿童记忆中组织策略发展的实验研究

本研究探讨了小学儿童组织策略的发展,结果表明:1.小学儿童组织策略的发展可分为产生性缺损和成熟运用组织策略两个主要阶段。第一个阶段根据是否伴随中介性缺损又可分为两个亚阶段。2.导致产生性缺损的原因有:(1)缺乏对记忆手段和记忆目标之间的功能关系的清晰认识;(2)不能清楚地认识策略的有效性,以及常运用自己熟悉的、简单的、但也相对无效的策略;(3)较差的有关记忆材料的知识基础以及较低的认识发展水平。     

青少年儿童四肢协调反应特征发展特点的研究

本文采用实验测试和横断对比分析的方法,对我国7—22岁的563名大、中、小学生和441名体操运动员的四肢协调反应特征发展特点进行了研究。结果表明:四肢协调反应的速度,在7—15岁期间有明显的发展提高,其中7—11岁为发展加速期,11—15岁为缓慢发展期;15—18岁为发展倒退期;18—19岁为恢复期;19—22岁为稳定期。这种反应的准确性在7—11岁有明显的发展提高;11—16岁为倒退期;16—22岁为恢复期。在体操运动的作用下,这种反应的速度和准确性发展,分别在9—12岁和10—17岁间明显加快;在青春期,反应的速度和准确性发展的波动性明显减少。     

Phonological representations in deaf children: the importance of early linguistic experience

It is argued that the development of phonological representations in deaf children does not necessarily depend on auditory speech experience, neither at the perception nor at the production level. Instead, this development depends upon early experience of an input in which all phonological contrasts are well specified, independently of input modality. This is argued on the basis of the studies investigating phonological and morpho-phonological abilities of profoundly deaf children early exposed to Cued Speech. The paper is concluded with some speculations about the effect of early exposure to CS on the development of language specific processes housed in the left-hemisphere.

A Religion for an Age of Science

The period 800–200 B.C.E. has been called an axial period or age because it was a period of major technological and cultural change that led to the development of new worldviews, which in turn called for and led to the emergence of the current major world religious traditions. The world is now in the midst of another period of major global scientific, technological, and cultural change that is leading to the development of a new global worldview. In this worldview, the cosmos is taken to be more like an activity than a thing—more like an emergent complex of interrelated and interactive doing in space–time than a created complex of beings in space and time–and its complexity and space—time scale are understood to be enormously greater than heretofore supposed.
These changes in worldview call for changes in theology, religion, and ethics. Most workers in the field of science and religion are heeding this call by attempting to reconcile traditional religious concepts with the new scientific concepts. Others, however, have become convinced that the new worldview differs so radically from the previous ones as to mark a new axial age, which calls for a new, post-traditional theology, religion, and ethics, with a theos that is more like an activator of doing than a ground of being, and with meaning and purpose achieved more by a quality of doing than a quantity or quality of being.     

注意力资源限制与双任务的相互干扰机制

采用心理不应期研究范式, 两个反应时实验检测了注意力资源分配的特征以及双任务的相互干扰机制。每次实验中, 要求被试快速、相继对高低音辨别任务(T1)和Stroop任务(T2)作出选择性反应, T1和T2间采用6种不同的时间间隔(SOA), 以系统考察不同SOA条件下两个任务的反应时走势。结果发现：(1) 在重叠的双任务情境中, T1的中枢加工导致在T2上出现显著的PRP效应, T2的中枢反应选择对T1的反应选择和反应执行加工同样产生显著的影响。SOA以及T2的难度与复杂度实质性地影响了T1的反应选择和反应执行加工。(2) 当两个任务同时需要进行中枢反应选择加工时, 一个任务占用更多的注意资源将导致另一任务获得较少的注意资源, 注意资源量的多寡直接决定了该任务的加工效率。(3) 两个任务的加工相互影响、相互制约, 这种制约机制不仅仅存在于中枢反应选择阶段, 在反应执行阶段仍然存在。     

How young children judge whether a word is one they know: a dual criterion account

Word familiarity judgment may be important for word learning, yet little is known about how children make this judgment. We hypothesized that preschool-age children differ in the judgment criteria that they use and that this difference derives from individual differences in basic memory processes. Those who have superior phonological working memory, but who retrieve less semantic information than their peers, base the judgment on whether they recognize a word’s sound form. Those who show the opposite memory profile base the judgment on whether they retrieve a word’s meaning. The results of two studies of 3- and 4-year-olds were consistent with these claims. Among those performing poorly on one memory measure, judgment accuracy was directly related to performance on the other memory measure. These memory-judgment relations were also found to be highly specific. This is the first investigation to demonstrate the usefulness of an individual differences approach for identifying relations between linguistic judgment processes and basic memory processes during early childhood.     

道学话语的形成、发展与转折——以宋代"定性说"的展开为中心

The formation of the discourse of Neo-Confucianism¹ in the Song period was a result of the interactions between many social and cultural trends. In the development of the Neo-Confucian discourse, the Cheng brothers (Cheng Hao and Cheng Yi) played key roles with their charismatic thoughts and impelling personalities, while Zhu Xi pushed Neo-Confucian thought and discourse to a pinnacle with his broad knowledge and precise reasoning. In the warm discussions and debates between different schools and thoughts, the Neo-Confucian discourse proceeded towards completion and perfection, and evolved as contemporary topics and thinking modes changed. The essay argues that “ding xing 定性 (stilling the nature)” was an important Neo-Confucian topic during the Song period. The doctrine of “stilling the nature” involves much central Neo-Confucian discourse such as the definition of xing 性 (human nature), the interior and exterior aspects of human nature, nature and qing 情 (feelings, sentiments), nature and xin 心 (mind, heart), nature and ren 仁 (benevolence, humanity, humaneness) and yi 义 (righteousness), nature and shi 事 (affair) or wu 物 (thing, object), the practice of preservation and cultivation, etc. Therefore, an examination of the formation, development and evolution of Neo-Confucianism is of great importance to the study of its early history. __________ Translated by Liu Huawei from Zhexue yanjiu 哲学研究 (Philosophical Researches), 2008, (1): 47–55     

从细节着手围手术期人文关怀

人文关怀不是能一蹴而就的工作,而是需要从细节着手贯穿始终的系统工程。作为麻醉医生,与患者的接触通常仅限于围手术期。除了为患者提供高质量的麻醉外,还必须注意围手术期的各种细节问题。只有把术前、术中、术后各个阶段的各种"小事"做好了,才能充分体现对患者的人文关怀。这既有利于患者的健康,也有利于建立良好的医患关系。
