How pigeons discriminate the relative frequency of events.

This study examined how pigeons discriminate the relative frequencies of events when the events occur serially. In a discrete-trials procedure, 6 pigeons were shown one light nf times and then another nl times. Next, they received food for choosing the light that had occurred the least number of times during the sample. At issue were (a) how the discrimination was related to two variables, the difference between the frequencies of the two lights, D = nf - nl, and the total number of lights in the sample, T = nf + nl; and (b) whether a simple mathematical model of the discrimination process could account for the data. In contrast with models that assume that pigeons count the stimulus lights, engage in mental arithmetic on numerons, or remember the number of stimuli, the present model assumed only that the influence of a sample stimulus on choice increases linearly when the stimulus is presented, but decays exponentially when the stimulus is absent. The results showed that, overall, the pigeons discriminated the relative frequencies well. Their accuracy always increased with the absolute value of the difference D and, for D > 0, it decreased with T. Performance also showed clear recency, primacy, and contextual effects. The model accounted well for the major trends in the data.     

Towards a topological philosophy

This article examines the use of mathematical concepts in philosophy, focusing on topology, which may be viewed as a modern supplement to geometry. We show that Plato and Parmenides were already employing geometric ideas in their research, and discuss three examples of the application of topology to philosophical problems: the first concerns the analysis of the Cartesian distinction between res extensa and res cogitans, the second the ontology of possible worlds of Wittgenstein's Tractatus, and the third Leibniz's monadology. We also consider the role of topology in mathematical explanations of the sort found in science, arguing that it can perform a role in philosophy that is of comparable importance.

The mediating mechanisms underlying the longitudinal effect of trait anger on social aggression: Testing a temporal path model

Social aggression is widely emerging among young adults and can cause social and psychological adjustment problems. Although trait anger is believed to affect aggression, the longitudinal effect of trait anger on social aggression has not been tested, and the underlying mechanisms are unclear. A temporal path model (TPM) was constructed to explain how trait anger longitudinally predicts social aggression. Three-wave data were collected in five provinces of China from 1209 valid young adults. The results showed that trait anger predicts social aggression through both hostile attribution tendency (an in-process tendency) and anger rumination tendency (a post-process tendency), and these tendencies may predict each other. The present study supports the idea of TPM for aggression and develops General Aggression Model.     

自主欺骗决策过程与结果评价的ERPs研究

本研究基于事件相关电位技术,以32名大学生为研究对象,采用2(诱发条件：高奖赏、低奖赏)×3(反馈类型：欺骗成功、欺骗失败、诚实)的组内实验设计,以点判断任务操控被试的自主欺骗水平,并结合欺骗及时反馈范式来操纵被试的结果评价。结果发现：(1)在决策过程,做出欺骗决策比诚实决策诱发更大波幅的P300;(2)在结果评价过程,相比欺骗成功反馈和诚实反馈,欺骗失败反馈诱发更负的FRN波幅。结果显示个体做出欺骗决策比诚实决策需要更多的注意资源参与和心理努力,并且对欺骗失败反馈的敏感度远高于欺骗成功反馈和诚实反馈。这一定程度上揭示了个体做出欺骗决策和面对欺骗结果时的心理和神经机制,为教育者采取必要措施来降低和预防青少年欺骗行为奠定了研究基础。     

心理旋转训练对5~6岁儿童空间能力和数学能力的影响

采用2（时间：前测/后测）×2（分组：实验组/控制组）的两因素混合实验设计,考察心理旋转游戏训练对5~6岁儿童空间及数学能力的影响。基于心理旋转的可塑性以及空间能力与数学能力之间的密切关系设计心理旋转干预方案,将36名被试分为实验组和控制组进行为期8周共24次的干预研究。研究结果表明：（1）空间能力与数学能力之间显著正相关;（2）心理旋转游戏有效地提高了5~6岁儿童的空间能力和数学能力,该训练方案具有良好的即时效果。     

数学学习不良的研究及趋势

认知心理学、神经心理学的研究发现了数学学习不良(MD)儿童的3种基本算术技能障碍:语义记忆型MD、程序型MD、视觉空间型MD,并对它们的机制和特征做了考察.近年来对MD儿童较高级数学问题解决的研究呈现如下特点:参与到该研究的领域很多;研究所涉及的认知和非认知因素增多;教学干预研究大量出现.目前MD研究在辨别MD儿童、缺陷的概念以及神经心理学解释上面临挑战.因此该研究领域的趋势是从发展的、整体的视角来考察影响MD的各种因素,并注意各种方法的革新和结合.     

Principle of organization: a dynamic-systems view of the archetype-as-such

The personality is a dynamic system. Like all other dynamic systems, it must be self-organized. In this paper I focus upon the archetype-as-such, that is, upon the essential core around which both an archetypical image and a complex are organized. I argue that an archetype-as-such is a pre-existing principle of organization. Within the personality that principle manifests itself as a psychological vortex (a complex) into which we are drawn. The vortex is impersonal. We mediate it through myths and rituals or through consciousness. In this paper I show that Jung's intuition about the archetype-as-such is supported by recent science. I evaluate other concepts of the archetype. My concept is different from that proposed recently by Saunders and Skar. My concept allows each archetype-as-such to be defined precisely in mathematical terms. It suggests a new interpretation of mythology. It also addresses our spiritual experience of an archetype. Because the archetypes-as-such are fundamental to the personality, the better we understand them the better we understand our patients. The paper is grounded with clinical examples.     

用典型相关进一步研究大学生亲社会倾向和亲社会推理的关系

本研究使用修订后的亲社会倾向量表(PTM)和亲社会客观推理量表(PROM),对大学生群体进行了测查,并采用简单相关和典型相关探讨亲社会倾向和亲社会推理的关系。结果表明:大学生的亲社会倾向由高到低依次为:紧急的、利他的、情绪的、依从的、匿名的和公开的;他们的亲社会推理由高到低依次是:需要定向、刻板定向、内化价值定向、享乐主义定向和赞扬定向。6种亲社会倾向都与刻板定向推理、内化价值定向推理正相关;紧急的、依从的亲社会倾向与需要定向推理正相关;匿名的亲社会倾向与享乐主义定向推理负相关。从典型相关分析结果来看,两者间的整体关联程度没有理论预期的高,典型变量所代表的亲社会倾向主要是紧急的、匿名的、依从的亲社会倾向,而这些亲社会倾向主要由内化价值定向推理、刻板定向推理、需要定向推理来解释。
