Stimulus Equivalence: Effects Of A Default-response Option On Emergence Of Untrained Stimulus Relations

Human subjects were exposed to a concurrent-chains schedule in which reinforcer amounts, delays, or both were varied in the terminal links, and consummatory responses were required to receive points that were later exchangeable for money. Two independent variable-interval 30-s schedules were in effect during the initial links, and delay periods were defined by fixed-time schedules. In Experiment 1, subjects were exposed to three different pairs of reinforcer amounts and delays, and sensitivity to reinforcer amount and delay was determined based on the generalized matching law. The relative responding (choice) of most subjects was more sensitive to reinforcer amount than to reinforcer delay. In Experiment 2, subjects chose between immediate smaller reinforcers and delayed larger reinforcers in five conditions with and without timeout periods that followed a shorter delay, in which reinforcer amounts and delays were combined to make different predictions based on local reinforcement density (i.e., points per delay) or overall reinforcement density (i.e., points per total time). In most conditions, subjects' choices were qualitatively in accord with the predictions from the overall reinforcement density calculated by the ratio of reinforcer amount and total time. Therefore, the overall reinforcement density appears to influence the preference of humans in the present self-control choice situation.     

儿童对图画喻意理解的比较研究

本文针对儿童对图画中隐喻情绪的识辨和理解的发展特点 ,进行了跨文化研究。旨在探索儿童对图画喻意的敏感性的发展规律以及不同教育方式对儿童图画认知发展的影响。 3 60名 4岁到 2 0岁的中英被试参加了实验。结果表明 :在识辨作品任务及口头评价中 ,中国儿童比英国同龄儿童更早理解图画的情绪喻意 ,并很少对图画的悲伤喻意持忽略态度。提示不同文化背景下 ,儿童对图画喻意的理解存在发展上的不均衡性 ,中国的幼教方式也许促进了儿童对图画喻意理解的发展。     

Judgment and decision making: Behavioral approaches

The area of judgment and decision making has given rise to the study of many interesting phenomena, including reasoning fallacies, which are also of interest to behavior analysts. Indeed, techniques and principles of behavior analysis may be applied to study these fallacies. This article reviews research from a behavioral perspective that suggests that humans are not the information-seekers we sometimes suppose ourselves to be. Nor do we utilize information effectively when it is presented. This is shown from the results of research utilizing matching to sample and other behavioral tools (monetary reward, feedback, instructional control) to study phenomena such as the conjunction fallacy, base-rate neglect, and probability matching. Research from a behavioral perspective can complement research from other perspectives in furthering our understanding of judgment and decision making.     

Neurological soft signs in obsessive compulsive disorder: standardised assessment and comparison with schizophrenia

While several studies have detected raised levels of neurological soft signs in patients with obsessive compulsive disorder (OCD), the specificity of these abnormalities remains uncertain. This study used a new standardised measure, the Cambridge Neurological Inventory (CNI), to assess soft signs in 51 subjects with OCD. Comparison was made with data on patients with schizophrenia and a non-clinical control group from a previously reported study. Individuals with OCD showed raised levels of soft signs compared with non-clinical controls in many categories of the CNI: Motor Coordination, Sensory Integration, Primitive Reflexes, Extrapyramidal Signs, and Failure of Suppression. Compared with patients with schizophrenia, the OCD group had lower levels of neurological signs in some CNI categories: Hard Signs, Motor Co-ordination, Tardive Dyskinesia, Catatonic Signs, and Extrapyramidal Signs. However, levels of soft signs in the OCD group did not significantly differ from those in the schizophrenia group in other CNI categories: Sensory Integration, Primitive Reflexes and Failure of Suppression. The significance of these patterns of findings is discussed.     

《共产党宣言》,欧洲与无产阶级政党

1848年问世的《共产党宣言》,是马克思和恩格斯参加的共产主义者同盟的纲领。毫无疑问,《宣言》是欧洲的,因为它在伦敦印刷,是由两个德国撰稿人完成的,这两个人在布鲁塞尔邂逅而且都加入了主要由德国人组成的、总部设在巴黎(后移至伦敦)的一个组织。可能正是由于警察的镇压,共产主义的幽灵才在欧洲徘徊。面对资本主义的世界化,革命者已经在反对资产阶级国际主义的实践,马克思和恩格斯于1843年夏天在巴黎相遇,而恩格斯曾谈到自这次相遇以来,他们已经有了一个理论的完整协议,他们第二次相遇在1844年春天,于布鲁塞尔,而恩格斯断言说,在那时,马克思“已经完全确立了他的历史唯物主义的学说”。     

维特根斯坦与心理主义的终结

我从一个顿号开始。这个逗号位于维特根斯坦《逻辑哲学论》里一个关键的命题中。对由这个顿号分开的词之间关系的解释,是最初的问题,后面的篇章把这个问题作为目标,加以阐明、研究并试图解决之。被这个顿号联系起来并隔开的词,指出了一些重要的概念,它们不仅可以在维特根斯坦的《逻辑哲学论》和他思想发展变化中找到,并且可以在总的哲学传统中找到。事实上,我们可以把这些概念看作关于语言、思想和实在三者关系的哲学问题的隐喻和线索。     

休谟关于“因果关系”的两个定义

鲁宾逊在最近哲学季刊上的一篇文章中认为，在休漠《人性论》一书中关于因果关系的两种定义并不是定义，而是一种根据经验的心理学论述即已经被确定的内容的定义。他的这个命题我不能接受，尽管他的那些次要的论题即（a）详细阐明了休漠所谓的“哲学关系”和“自然关系”，（）与史密斯相反，休漠支持因果关系的“统一性”观点确实是合理的。因此我希望（I）能够解释为什么鲁宾逊的主要命题不能真正说明休漠的两个因果关系定义，（巨）并证明他的结论并不是来自他自己的论述（巨）试图解释体漠关于“因果关系”的两个定义，这可以较真实地…     

增补的危险性

我们让人反复理解这一点:对生动话语的称赞忠诚于卢梭思想中的一个主题,这个主题和它的对立面结合并组织起来:对所谓完满话语始终越发怀疑。讲话过程中,在场获得承认的同时亦遭到拒绝。卢梭提出话语高于书写的谈话应该是,或本该是明明白白的。我们必须注意这种方式,注意在生动的谈话中把我们与在场联系起来的时刻。实际上,卢梭体会到直接的话语奇迹和话语本身内所隐蔽的东西,以无可比拟的敏锐性承认并分析了这个遮盖物,我们尝试通过语言的表示抓住所渴望的在场,但我们失掉了它。斯塔罗宾斯基在《活的眼睛》中
