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。     

摧毁与解构

当海德格尔把理解这个主题从一种人文科学的方法论学说,提升为此在的本体论的生存论环节和基础时,解释学维度就不再意味着现象学的植根于具体知觉的意向性研究的一个较高层面了,而是以欧洲为基地,把几乎同时在盎格鲁撒克逊逻辑学中实现的“转向语言”在现象学研究思潮中突现出来了。在胡塞尔和舍勒尔对现象学研究的最初展开中,尽管有向生活世界的各种转向,但语言问题依然是完全蔽而不显的。     

Standardized classroom management program: Social validation and replication studies in Utah and Oregon

A comprehensive validation study was conducted of the Program for Academic Survival Skills (PASS), a consultant-based, teacher-mediated program for student classroom behavior. The study addressed questions related to: (a) brief consultant training, (b) subsequent teacher training by consultants using PASS manuals, (c) contrasts between PASS experimental teachers and students and equivalent controls on measures of teacher management skills, student classroom behavior, teacher ratings of student problem behaviors, and academic achievement, (d) reported satisfaction of participants, and (e) replication of effects across two separate school sites. Results indicated that in both sites significant effects were noted in favor of the PASS experimental group for (a) teacher approval, (b) student appropriate classroom behavior, and (c) four categories of student inappropriate behavior. Program satisfaction ratings of students, teachers, and consultants were uniformly positive, and continued use of the program was reported a year later. Discussion focused upon issues of cost-effectiveness, differential site effects, and the relationship between appropriate classroom behavior and academic achievement.     

对马克思早期哲学思想发展的新认识

一九七五年新出版了马克思恩格斯全集第一辑第一卷,现在又出版了第四辑第一卷。对于马克思一八三九年初至一八四一年三月哲学思想的发展,这两卷提供了一些新的研究成果。这些新的研究成果,修正了这个时期流传下来的手稿——它们同时是马克思研究哲学的最初文献——的形成史,精确规定了这些手稿的形成时间,并确定了原文的编排和翻印。流传下来的手稿包括:关于伊壁鸠鲁的七册摘要笔记(有一部分成了不同题目的独立的补遗)、     

新托马斯主义批判

天主教教会及其意识形态特征对新托马斯主义哲学进行考察,必须先简略分析天主教教会在当今世界上的地位及其意识形态的一些特征。十九世纪后半叶,天主教教会从封建制度和君主制政体的卫士,变为反对工人阶级运动、反对社会主义、维护资产阶级的一种武器。天主教教会是教权主义运动中的一支极其强     

辩证逻辑

黑格尔对形式逻辑和辩证逻辑的看法辩证逻辑是德国哲学家黑格尔在十九世纪初引入的哲学术语。这个术语是他用来称呼自己关于一切“自然和精神事物”发展的规律的唯心主义学说的,又同被他作了歪曲解释的形式逻辑直接地对立起来。他正确地指出了他那个时代哲学理论的弊病之一,就是思维的规律和形式被形而上学地看作为某种一成不变的东西。其实,受工业生产的进步所制约的自然科学的发展已经表明,形而上学和它的     

Effects of a token reinforcement system on journal reshelving

A token reinforcement program involving two levels of token value and backup reinforcers to increase journal reshelving behavior in a large university library was experimentally evaluated. Results showed that instructions (in which signs asked users to reshelve journals) had no impact. By contrast, token reinforcement contingent on reshelving behavior led to a marked increase in journals reshelved. A return to instructions-only conditions, when data were corrected for library usage, showed an increase in unreshelved journals over the token reinforcement period, though the increase was not to baseline levels. For the next 11 months, library staff maintained a modified token program. Follow-up data collected after that interval showed that number of unreshelved journals remained markedly lower than levels at baseline and the first instructions-only period, though they were slightly higher than at the token reinforcement period. Token reinforcement of the variety employed in this study constitutes an efficient, economical means of changing the behavior of library users who fail to reshelve books and journals.
