论库恩的《科学革命的结构》和科学发展的辩证法

本世纪六十年代资产阶级科学哲学演变的特点是同在此以前占统治地位的实证主义坚决分道扬镳。“在现代自然科学和社会科学的哲学中,主要倾向是反实证主义”——西方现代逻辑学-方法论的刊物上常常这样说。对这一现象进行历史和哲学的     

解释康德学说的几条途径——第四届国际康德讨论会情况报告

H.劳纳教授领导的伯尔尼方法论研究所(F.格瑞特联合会)于1980年5月1日至4日召开了一次康德哲学讨论会,有十一篇论文讨论了康德哲学的各种问题。讨论会不但表明了,对康德的解释存在着巨大的困难,而且也表明了,康德的学说仍有着重要的现实意义,对康德学说的兴趣已打破了语言的界限和哲学的传统。在这一方面最突出的例证就是那些试图用(内涵)逻辑的形式方法来解释康德某些著作的论文。 L W.贝克的《康德论自然界的规律性》,E.埃     

Stimulus control of respondent and operant key pecking: A single key procedure

Pigeons' responses to a uniformly illuminated response key were either reinforced on a variable-interval one-minute schedule of reinforcement or extinguished for one-minute periods. When 1.5 second signals were presented at the beginning of each component, so as to differentially predict reinforcement, the pigeons pecked at the signals, at rates higher than rates during the remainder of the component. When the brief signals were not differentially predictive of reinforcement, pecking in their presence decreased to near zero levels. Similar results were obtained with signals based upon colors and upon line orientations. Changes in rates of (unreinforced) pecking occurred during the signal whether pigeons responded differentially during the remainder of the component or not. Experiment II demonstrated that the presence of the signal correlated with extinction was not necessary for pecking to develop at the signal which preceded the component in which responding was intermittently reinforced. The experiments demonstrated a clear dissociation of respondent control from operant control of a response. In addition, operant behavior was shown to be relatively insensitive to differing rates of reinforcement, as compared to the sensitivity of respondent behavior to differing rates of reinforcement produced by the very same operant behavior.     

Concurrent schedules: Spatial separation of response alternatives

Four pigeons were exposed to independent concurrent variable-interval 20-second variable-interval 60-second schedules of reinforcement. A transparent partition was inserted midway between the two response keys. The length of the partition was systematically manipulated. Increasing partition length produced a decrease in changeover rate in Experiment 1. Over-matching was observed with a partition length of 20 centimeters. In Experiment 2 a four-second limited hold was added to the schedules. Increasing partition length produced a decrease in changeover rate that exceeded the decrease observed in Experiment 1. This manipulation produced nearly exclusive choice of the variable-interval 20-second component. The present results, together with results obtained in related research, suggest that deviation from matching is a function of procedural variables that determine the consequences of a changeover response.     

GPS,一个模拟人类思惟的程序

GPS 是 General Problem Solver(通用问题解决者)的缩写,是一个计算机程序的名称。GPS 是用来探讨人工智能的一个重要手段,同时,它的各种变式也对人在解决问题时的思惟进行了模拟。GPS(以及在它之前的 Logic Thcory Machine,简称 LT 程序)的建立,标志着对思惟心理学的研究从传统的实验心理学方法跨入了信息加工的领域,用信息加工的观点和方法来探讨人的思惟行为。它为思惟心理学的研究,开拓了更广阔的前景。本文主要讨论 GPS 对人解决问题时的思惟行为的模拟,讨论人的思惟的心理学问题。     

《古兰经》的伦理道德思想(续)

三、敬畏 敬畏是一种宗教美德,《古兰经》用它来确定人与人、人与造物主之间的关系。“敬畏”一词及其派生词大都出现在《古兰经》中有关道德和社会主张的经文中。所谓“敬畏”就是要人类谨防那些使真主恼怒和损人害己的行为。因为“敬畏”一词本意为保护自己。人之所以保护自己,是因有可惧怕的东西存在。安拉是最值得惧怕的,所以因安拉而保护自己是特别重要的。既然惧怕,就

七、公正 伊斯兰教的理想之一就是责成其信徒要丢掉一切与自身利害有关的考虑,主持人间公道。安拉说:“信教的人们!你们应主持公正,应为安拉而作见证,即使不利于自身,或自己的父母和亲属。不论被见证者是富人或贫人,那安拉是最宜于对付他们的。你们不要徇私,以免偏离公正;如果你们歪曲事实,或拒绝作证,那安拉对你们的作为将是一清二楚。”(4:135)     

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
