认知风格与教学策略(节译)

一般地说,认知风格可以被理解为个人感知、组织以及评价信息的独特方式。然而,除此之外,本文要论及的四项系列研究运用了两种量表,它们反映了对认知风格的不同而独特的解释。一种量表是迈尔斯—布立格斯类型量表(Myers—Briggs Type lndlcator),这是一套著名的量表,它是以荣格(Jungian)的人格理     

呼图白集(续六)

朱马达·阿黑赖第一讲赞美安拉——造化所有万物的主,开天辟地的主,布施给养的主。巢中群鸟赞他清净,各路王侯颂他崇高。赞主清净,他是崇高普施的主,其拥有之财富不因博施而罄绝。我赞美安拉清净玄高,赞主会持续给     

逻辑的范围

人们在作出陈述时,可能提供论据以支持它们,也可能不这样。一个被论据支持的陈述是一个论证的结论,而逻辑则提供对论证进行分析的工具。逻辑分析所涉及的是结论和支持它的论据之间的关系。人们思考时,作出推理,这些推理可以转变为论证,而逻辑工具这时就应用于这些得出的论证之上。这样,就可以检验产生这些论证的推理。逻辑研究论证与推理。它的主要目的之一是为区别逻辑上正确的与不正确的论证与推理提供方法。     

排中律与多值逻辑

(在这篇论文里,我把多值逻辑中反对排中律的论据找来,并试图对其进行一番考查。首先,我叙述了反对排中律的论据,然后试图对它的力量作出估价,凡是这个论据显得不充分之处,我就试着提出一种理由予以支持。在我时这个理由所作的批评里,我也努力对提出这一否定的动机——引起争论的那些东西,以及这一否定的份量如何,作了某些证明。) (一)导言传统逻辑的法则基本上是从亚里士多德流传下来的。传统逻辑最基本的法则就是三大思维规律。第一条是同一律,其内容是:“A就是A”或者是“如果某命题是真的,那么它就是真的。”第二条     

科学革命的几个阶段

过去的10年中,科学史家和科学哲学家掀起了一场对科学革命或科学进步的方式进行各种各样分析的热潮。在此期间出版的大量文献中,很多都对这些分析中的这种或那种分析内在的一致性、广泛的适用性或普遍的应用等问题进行了一系列的论证,争论的主要部分集中在T.S.库恩的思想上。库恩的论述很独特,它们都是以“范式”这个概念为基础的。所谓范式,就是一组共有的方法、标准、解释方式或理论,或者说是一种共有的知识体。在库恩看来,所谓科学中的革命,就是这样的一种范式向另外一种范式的转换,他认为,科学形势     

Interval and ratio reinforcement of a complex sequential operant in pigeons

Pigeons were required to produce exactly four pecks on each of two keys in any order for reinforcement. Correct response sequences were reinforced on either fixed-interval two-minute or fixed-ratio four schedules, with each correct sequence treated as a single response. Each pigeon developed a particular dominant sequence that accounted for more than 80% of all sequences. Sequence stereotypy was relatively unaffected by the temporal properties of the fixed-interval and fixed-ratio schedules. Response time (time from the first response in each sequence to the last) was also relatively unaffected by the temporal properties of the schedules. In contrast, response latency (time from end of one sequence to the beginning of the next) was markedly affected by the schedules. Latencies were long early in the interreinforcement interval and got shorter as the interreinforcement interval progressed. These data suggest that stereotyped response sequences become functional behavioral units, resistant to disruption or alteration by reinforcement variables that ordinarily influence the temporal spacing of individual responses.     

社会主义社会的无神论和精神文化

在苏联,由于经济和社会关系的伟大革命改造,建成了发达的社会主义社会。苏联的生活方式决定了社会意识的普遍无神论化,因此,在苏联社会生活中,科学无神论的社会功能和文化功能得以充实和扩大,科学无神论同物质和精神实践的各方面、各领域的联系得以巩固和完善。在信教者中间,虔诚狂热的信徒逐渐减少,这类现象证明,宗教在我国社会中的影响正在减退。     

An analysis of motor coordination components for various localization tasks

Localization abilities of subjects in three perceptual-motor tasks were considered before and after an exposure to a visual distortion. During this distortion the subject observed his hand ballistically point to an invisible but audible target while either receiving or not receiving knowledge of results (KR) concerning pointing accuracy. Also, subjects either received a 1- or a 4-sec rest period between each of 30 exposure ballistic pointing actions. The pre- and postexposure tasks involved the ability of a subject to accurately point to an occluded and stationary auditory target, to point to the straight-ahead position in space, and to indicate when a moving, auditory target was perceived as being in the straight-ahead position. For these tasks, the pre- vs. postexposure localization difference scores are referred to as the negative aftereffect, the proprioceptive shift, and the auditory shift, respectively. Wilkinson's (1971) two-component additive model (negative aftereffect = proprioceptive shift plus auditory shift) held when KR was given regardless of amount of rest between exposure pointing responses. With a 4-sec rest and no KR, the relationship between coordination components was nonadditive (negative aftereffect greater than proprioceptive shift plus auditory shift).     

On the limits of Kagan’s impulsive reflective distinction

A logical analysis is made of the Matching Familiar Figures (MFF) Test on the basis of which children have been classified as "impulsive" or "reflective." The reflective strategy is implicitly preferred to the impulsive because the reflective child makes fewer errors though generally taking longer to make his first response. We show that the test allows the choice of a number of "game plans" and speed-accuracy tradeoffs which in practice may not be very different. Error rates may not indicate perceptual sensitivity, in any case, since sensitivity and response factors may be confounded in the error rate. Using a visual running-memory-span task to avoid the inherent difficulties of the MFF test, we found that children previously classified on the basis of that test as impulsive or reflective did not differ in recognition accuracy but did differ in response bias and response latency. Accuracy and bias are estimated by way of Luce's choice theory (Luce, 1963), and the results are discussed in those terms.     

历史与进步

这篇文章,从神学和科学的折衷主义的立场出发,借进化论的名义,替资本主义制度辩护。作者认为:资本主义一直表示着以自由为特征的历史的进步、现在只有西欧各国结成强大的同盟,保持西欧国家的精神上和实力上的因素,才能实现“全人类的自由”;而“从来不知道什么是自由的”其他地方实现其新世界的那种方法,是“不会导致自由”的。
