萨特尔和他的《辩证理性批判》

萨特尔写的《辩证理性批判》(1960)实际上是他历史论的第一卷。这是一本令人兴奋而又晦涩难懂的著作,它那令人眼花缭乱的分析连接着离题万里的议论,天才的见解埋没在曲折的思路和叙述的沙漠中,人们总是无法弄清楚他是朝着哪条道路行进。在进行综合的崇高意愿背后,该书还显示了它的抱负:“对历史的认识在什么条件下才是可能的?在怎样的范围内,那些被揭示的联系是必要的?什么是辩证的理性?”(第135页,以下未注书名的均指《辩证理性批判》)这种计划表面看来是康德主义的,但它的新颖性又说明它是来自我们时代不可超越的理论——马克思主义。这本著作注意的就是这两方面要求的结合。这位战士和介     

阿尔都塞的多元决定与结构因果观

在阿尔都塞的马克思著作研究中,多元决定和结构因果性这两个概念是十分重要的。本文将通过考察阿尔都塞对这两个概念在理解马克思的“方法论”上的价值和应用的论述,来解释这两个概念。但这种研究方法并不认为在《资本论》或其他著作中,马克思实际上有一种具体的或明确的方法论。对我们来说,马克思主义中是否有方法论仍然是一个未解决的问题。对于任何的马克思方法论的探讨,这些概念都是重要的。本文的任务之一就是表明,马克思在政治经济学中的贡献和“理论革命”不能简单地用方法论来描绘。马克思对黑格尔的辩证法思     

Contributions of elicitation to measures of self-control

Pigeons' not pecking or pecking constituted choice between a delayed, large reinforcer and an immediate, small reinforcer (self-control) and at other times between a delayed reinforcer and no reinforcer (omission). Both a tone and a keylight were tested as choice signals, and the delayed reinforcer was either response independent or response dependent. Pigeons pecked during the choice signals on over 95% of the trials in the self-control procedure, and pecked during the choice signals on over 75% of the trials in the omission procedure. Consistent pecking was observed with either the tone or the keylight as a choice signal, with the exception that a tone paired with a response-independent delayed reinforcer did not maintain pecking in the omission procedure. Pigeons pecked during more choice signals when delayed reinforcers were response dependent than when the delayed reinforcers were response independent. These results indicate that Pavlovian conditioning influences self-control experiments, especially in single-key procedures.     

Reply to silberberg and ziriax

Silberberg and Ziriax (1985) report that a modification of Vaughan's (1981) procedure produces results inconsistent with melioration (the position advocated by Vaughan) but consistent with a process they term molecular maximizing. Here it is argued that the theory of molecular maximization is not sufficiently unambiguous that researchers other than the developers can test its predictions, and that in any case none of the data presented by Silberberg and Ziriax are both clearly consistent with molecular maximization and inconsistent with melioration.     

A scale for measuring persistence in children

Persistence and its assessment have been studied since the 1920s. One common approach in measuring persistence has been through testing the subject's ability to solve difficult or monotonous problems. Another approach has been through questionnaires. Although persistence is very important in academic achievement and in the general development of personality, no questionnaires have been developed for measuring persistence in children. The present research concerns the development of such a scale. It includes 40 items and was tested on 322 Israeli children aged 7-13. The internal reliability of the scale (Cronbach alpha) was .66, and the test-retest reliability after 6 months was .77. The scale differentiated active gymnasts from non-gymnasts as well as persistent gymnasts from dropout gymnasts. In addition, significant correlations were found between the scale and the need-persistence measure of the Rosenzweig Picture Frustration Study, Locus of Control, and other measures. We discuss these findings along with the significance of persistence in everyday life.     

Competitive fixed-interval performance in humans

Two persons responded in the same session in separate cubicles, but under a single schedule of reinforcement. Each time reinforcement was programmed, only the first response to occur, that is, the response of only one of the subjects, was reinforced. “Competitive” behavior that developed under these conditions was examined in three experiments. In Experiment 1 subjects responded under fixed-interval (FI) 30-s, 60-s, and 90-s schedules of reinforcement. Under the competition condition, relative to baseline conditions, the response rates were higher and the pattern was “break-and-run.” In Experiment 2, subjects were exposed first to a conventional FI schedule and then to an FI competition schedule. Next, they were trained to respond under either a differential-reinforcement-of-low-rate (DRL) or fixed-ratio (FR) schedule, and finally, the initial FI competition condition was reinstated. In this second exposure to the FI competition procedure, DRL subjects responded at lower rates than were emitted during the initial exposure to that condition and FR subjects responded at higher rates. For all subjects, however, responding gradually returned to the break-and-run pattern that had occurred during the first FI competition condition. Experiment 3 assessed potential variables contributing to the effects of the competitive FI contingencies during Experiments 1 and 2. Subjects were exposed to FI schedules where (a) probability of reinforcement at completion of each fixed interval was varied, or (b) a limited hold was in effect for reinforcement. Only under the limited hold was responding similar to that observed in previous experiments.     

目的、意向和意识

本文提出了一个意向性目标搜寻的计算机模型,它有两个部分,静态部分包括一个目标表征和到达这个目标的程序。动态部分是一个感觉输入、中间信息加工,行为输出的重复的反馈循环。人类意向必然伴有意识,但机器人则可能无意识而有意向。 利用目标搜寻系统机器人模型,我们对目标搜寻系统的目的连续统下了定义;这个连续统从简单的直接反应系统一直到意向性系统。对这个目的连续统有两种传统的解释:一是柏拉图、亚里士多德和普罗提诺的终极原因理论,二是希腊原子论者和现代进化生物学家的还原主义学说。本文评价了这些学说。 本文考察了几种类型的意识机能,提出了以自动机为依据的意识理论,比较了人类和计算机。从计算机结构的角度来看,人类意识是一类特殊的计算机控制系统。     

攻击的社会性认知学习的调节

这项研究探索了小学儿童的攻击与影响儿童是否采取攻击行为的社会认知的两个等级的联系.给攻击性和非攻击性的儿童(平均年龄为11.3岁)提供二个调查表,让他们进行回答.一个调查表是测量儿童对自己进行攻击的能力及相应的行为的认识(即自我实力的认识),而另一个调查表则测量儿童对攻击性行为会得到的奖励和惩罚的后果的认识.     

对算术和阅读中的成就与态度的长远预见

 这项纵向研究的目的在于了解:(1)在幼儿园里所提供的认知任务对儿童的学业成就的预见性;(2)教师和母亲对儿童的一般认知能力和实际成就的评价对于学业态度的预言性.在进入幼儿园以前对儿童进行初试,255名幼儿园儿童被追踪到一、二、三、五、十年级,认知任务中的一个分项目与中学成就分数保持着相关,特别是在阅读方面.十年级儿童的能力的自我概念、成功期望、成功的价值以及对任务难度的认识都表现出性别和学习内容范围的影响.男孩往往偏爱算术,而女孩则更喜欢阅读.儿童的学业态度与母亲对他的早期评价及实际成就分数都有相关,女孩尤为如此.母亲的评价与女孩对算术的态度有正相关.在全部11个年龄时期中都存在着性别差异.
