在本章的标题中,我之所以这样称呼鲍波尔,是因为他的哲学主要是为德意志联邦共和国垄断国家改良主义提供理论依据效劳的。不过,我要避免使人产生这样一种印象,好象鲍波尔的哲学并没有被保守势力所利用似的。比如属于鲍波尔“批判理性主义”圈子里的托皮奇(Topitsch),就是一位露骨的保守人物。鲍波尔的哲学成了资产阶级“社会工艺学”,(Sozialtechnologie)一切变种的总根子。  相似文献

绝大多数人是用视觉系统来辨别颜色的。但是,也有人能用手指辨认颜色。心理学家扎瓦拉(Zavala)、范科特(Van Cott)、奥尔(Orr)和斯莫尔(Small)对一个自称能用手指辨认颜色的人进行了广泛的研究并于一九六七年发表了研究结果。他们用多种作业让被试辨认。有一次让被试蒙住眼睛后对不同颜色的朴克进行分类。测查证明她是成功的,超过了简单猜测的水平;能够把红色和白色、红色和兰色区别开来,但不能区别兰色和白色。另外一次测试,她能确定在她手上是否有一道光照。照射到手上  相似文献

Edward Stanton Sulzer was born in New York City on June 4, 1930. He attended school in Laureltown, N.Y., until the age of 15, when, after two years of high school, he was admitted into the University of Chicago. Leaving prematurely due to his mother's death, he returned to New York to work in film production. Sulzer completed his undergraduate work at the City College of New York, studying film production and psychology. In 1953 he entered the doctoral program in clinical psychology at Teachers College, Columbia. Spending two years in the Army during his graduate training, his work was completed in 1958. He then joined the faculty of the Upstate Medical School of the State University of New York, Department of Psychiatry, moving on two years later to the Psychiatry Department at the University of Minnesota. In 1965 Sulzer moved to assume the directorship of the Behavior Modification Program, in the Rehabilitation Institute at Southern Illinois University, where he remained until his death on February 28, 1970.In observance of the 10th anniversary of the death of Edward Stanton Sulzer, these reminiscences are presented. They describe how an individual psychologist could affect the professional and personal lives of many. Edward Sulzer is described in terms of the environment that shaped his values, how they affected the actions of his students and clients, and how they are reflected in current social policy. The account leads to a conclusion that the actions of single individuals may influence the course of human events.  相似文献

Although the Bender-Gestalt Visual Motor Test has been a popular and influential clinical assessment instrument for the last half century, authoritative opinion and a substantial research literature are often inconsistent or contradictory. This paper documents variations in designs, administration procedures, forms, and applications to particular populations. A careful review of scoring systems indicates the current status of objective approaches as contrasted with interpretation that is global, intuitive, and subjective. Some implications of these variations and interpretive procedures for training and assessment practice are discussed. The major conclusions of the review are summarized in seven points.  相似文献

Five-year-old children were taught three-stage sequences of arbitrary matching: A-C, B-C, A-D; A-C, B-D, B-C; or A-C, A-D, B-C. Each stage refers to a sample-comparison relation between stimuli. Unreinforced test probes revealed untrained arbitrary matches (B-D, A-D, and B-D, respectively), derivable by substitution of stimuli with a common sample or comparison function. Additional probes revealed further untrained sample-comparison relations derivable by substitution and identity, including the commuted relations D-B, D-A, and D-B, respectively. These processes may have relevance to conceptual and verbal behavior.  相似文献

The fixed-interval schedule of reinforcement is one of the more widely studied schedules in the experimental analysis of behavior and is also a common baseline for behavior pharmacology. Despite many intensive studies, the controlling variables and the pattern of behavior engendered are not well understood. The present study examined the microstructure and superstructure of the behavior engendered by a fixed-interval 5- and a fixed-interval 15-minute schedule of food reinforcement in the pigeon. Analysis of performance typical of fixed-interval responding indicated that the scalloped pattern does not result from smooth acceleration in responding, but, rather, from renewed pausing early in the interval. Individual interresponse-time (IRT) analyses provided no evidence of acceleration. There was a strong indication of alternation in shorter-longer IRTs, but these shorter-longer IRTs did not occur at random, reflecting instead a sequential dependency in successive IRTs. Furthermore, early in the interval there was a high relative frequency of short IRTs. Such a pattern of early pauses and short IRTs does not suggest behavior typical of reinforced responding as exemplified by the pattern found near the end of the interval. Thus, behavior from clearly scalloped performance can be classified into three states: postreinforcement pause, interim behavior, and terminal behavior.  相似文献

现在我们联系整个马列主义哲学的对象的定义来研究辩证唯物主义的对象的定义问题。不能把一定数量的定义的并存看作是哲学知识的科学性不足的标志。凡是研究结构复杂的客体的理论科学都会有这种情形。列宁在摘录黑格尔的《逻辑学》时指出:“定义可能有许多,因为对象有许多方面”,接着,他引用黑格尔的话:“被下定义的对象愈丰富,也就是说,它  相似文献

马克思在巴黎时期(1844年)的经济学—哲学手稿的最后一章中研究了《精神现象学》;特别是它的最后一章——绝对知识。马克思采取的方法是把现象的意识阐述从同一哲学的框框中解脱出来,以便阐明隐藏在同一哲学中的、往往已经“远远超过黑格尔观点”的批判要素。他在这里涉及到《全书》第381和第384节,在这两节中完成了从自然哲学向精神哲学的  相似文献

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。  相似文献
