心算的加工机制：来自认知神经科学的研究

心算加工分编码（表征）、运算（或提取）和反应三个阶段,这三个阶段相互影响。不同输入形式的数字表征在顶叶的不同区域完成。算术知识提取主要与左脑顶内沟有关,但当心算变得更复杂时而需要具体运算时,左脑额叶下部出现明显激活。所有与心算有关的脑区涉及大脑前额皮层和颞顶枕联合皮层的综合作用,并总体表现为左脑优势,但估算、珠心算以及某些具有特殊心算能力的人的心算还依赖视空间表征,这与右脑额顶区和楔前叶的活动有关     

心算加工的认知神经科学研究

近几年(1999-2005)有关心算加工的脑活动机制研究发现,类似九九乘法表这样的算术知识提取(如3×5)主要与左脑顶内沟有关,但当心算变得更复杂时(如26×38),左脑额叶下部出现明显激活,这表明心算与语言和工作记忆关系密切。另一方面,也存在不依赖于语言的即表现为视觉表象活动的心算,右脑的一些脑区在其中起了作用。简言之,所有与心算有关的脑区涉及到大脑前额皮层和颞顶枕联合皮层的综合作用,并总体表现为左脑优势,但具有特殊心算能力的人其心算还与右脑前额叶和颞叶内侧脑区的活动有关。     

工作记忆子成分在听觉障碍儿童心算过程中的作用

采用2×2×3的混合实验设计,比较听力正常儿童和听觉障碍儿童在心算作业上的差异,考察了工作记忆子成分在听觉障碍儿童心算过程中的作用。结果表明,与听力正常儿童相比,听觉障碍儿童在高存储负载水平下的心算成绩显著降低,说明语音回路负责心算过程中的存储成分;而且听觉障碍儿童在对中央执行能力有高需求的实验条件下的作业水平并不比正常听力儿童差,说明他们的中央执行能力并没有受到损失。     

青老年组不同难度下心算活动的脑功能磁共振成像研究

应用功能磁共振成像技术研究不同心算难度下脑区的活动以及年龄的影响。14名志愿者（20～29岁青年和60～69岁老年被试各7名）参加了该实验。实验任务为2个难度水平的连续减法心算,分别为1000—3和1000—17。结果表明：（1）心算加工激活了额叶和顶叶的许多脑区;（2）大脑左半球是心算加工的优势半球,但随着心算难度加大,大脑一侧化程度下降,而年老加剧了这一趋势;（3）青年组进行简单心算（1000—3）时,额中回未见明显激活,而老年组进行简单心算时,该脑区被明显激活。总体上,额叶和顶叶在心算活动中起着重要作用,而任务难度和年龄对心算加工时脑活动的影响以额中回区最为明显。     

计算的脑科学研究及其对数学教育的启示

脑科学研究发现,简单心算主要涉及算术事实的提取,依赖于左半球的语言中枢,而复杂心算激活了左侧顶—额叶网络和双侧颞下回,与视觉空间表征和视觉表象加工有关;精算主要激活左额叶下部区域,而估算激活了两半球更大的区域。在计算过程中所激活的脑区受年龄发展与个体差异以及训练的影响。研究对有效地促进儿童计算能力的发展提供了重要启示。     

珠心算训练儿童加法心算的ERP早成分研究

采用事件相关电位(ERP)的方法,对32名儿童进行了双位数加法心算实验,探讨了珠心算训练方式对儿童加法心算加工早期感知觉的影响。研究结果表明,与非珠心算训练儿童相比,在加法心算过程的早期阶段,珠心算训练儿童枕部P1、额中央区的N1波幅增大,而颞枕区N170以及额中央区P2波幅减小。本研究结果发现珠心算训练对儿童心算过程的早期感知有显著影响。     

数量空间表征的特点:跨视听通道下的SNARC效应

从跨通道的角度入手,采用大小比较任务,对视听单通道及跨通道下数量空间表征的特点及表征过程中的相互影响进行探讨。结果发现,视觉通道和听觉通道均存在SNARC效应;在跨通道任务下,无论启动通道是视觉还是听觉通道,都表现出,当启动通道的数量大小信息与主通道的数量大小一致或无关时,主通道的SNARC效应没有显著变化;但当启动通道的数量大小信息与主通道不一致时,主通道的SNARC效应受到显著影响,表现为降低或消失。这进一步证明了SNARC效应受情境影响的特点,并发现在进行跨通道数量空间表征时,听觉通道的数量信息对视觉通道下的数量空间表征的影响大于视觉通道的数量信息对听觉通道下的数量空间表征的影响。     

表象激活混淆与错误记忆的关系——来自ERP研究的证据

采用ERP技术考察表象激活混淆与错误记忆的关系。发现:(1)在编码阶段,随后错误记忆的ERPs比随后正确记忆的ERPs在顶区、枕区和颞枕区有更大的晚正成分。(2)在提取阶段,错误记忆的ERPs比正确记忆的ERPs在顶区、枕区和颞枕区有更大的晚正成分。整个研究表明,表象激活混淆在错误记忆产生中具有重要作用。根据研究结果提出"表象激活混淆假设",认为人们虽然使用表象的信息表征方式,却无法获取与之联系的激活路径,容易混淆表象激活的来源。表象激活混淆是表象引发错误记忆的机制。     

不同数学焦虑成人的算术策略运用差异：ERP研究

采用事件相关电位(ERP)技术和选择/无选法范式, 在两位数加法心算和估算中, 探索高、低数学焦虑个体的算术计算策略运用及其内在机制。行为结果：数学焦虑效应在策略运用的反应时和正确率指标上的差异都不显著; 而脑电结果：高数学焦虑个体的N400波幅显著高于低数学焦虑个体; 选择条件中, 估算与心算的数学焦虑效应的N100波幅差异; 无选条件中, 高低数学焦虑个体N1-P2复合波的波幅和潜伏期差异显著。数学焦虑效应在策略编码(0~250 ms)和策略选择/执行阶段(250 ms之后)存在差异。     

心算困难儿童的语音复述

心算中语音复述和计算加工交替进行,其中任何一方面落后都会导致心算困难。使用视觉心算成绩和听觉心算成绩相减的范式,研究计算能力正常但心算水平落后的儿童的语音复述水平。结果发现,不同年级心算困难儿童呈现不同的困难模式,2、4年级心算困难儿童语音复述水平正常,但由于语音工作记忆容量的落后,导致缺少足够的注意资源进行计算加工。3年级心算困难儿童在语音工作记忆容量和语音复述上都存在落后,导致心算困难,呈现出双重困难模式。     

Seeing and hearing and space and space and time

A previous experiment had shown spatial location to be judged in terms of the framework provided by the modality in which stimuli were presented. In the present study, digits were either auditorally or visually presented, and in either form the three digits appeared successivly to the left, in the center, and to the right of the S. The digit which occurred temporally in the middle of the sequence was never central from the spatial viewpoint. The S was asked to indicate which digit was the middle one. Ss were blind, deaf, or normal. The deaf and two control groups saw visual displays, and the blind and their controls heard auditory displays. The former groups predominantly chose the spatially middle digit and the latter groups the temporally middle. It was concluded that modality of presentation was the trigger which switched in the coding dimension of time or space.     

Bob and Carol and Tess and Ali

Conflicting religious experiences in different traditions do not necessarily defeat the rationality of conflicting beliefs sustained by those experiences in those traditions. The circularity that protects religious beliefs from such mutual defeat is not vicious. Moreover, the lack of ‘epistemological humility’ exhibited by such believers poses no threat to world peace. In fact, a campaign for compulsory humility would itself constitute a much greater threat.     

Law and Gospel,and Youth and Family Ministry

Abstract : If “faith comes through hearing” the word of God comprised in law and gospel, how do the imperatives that characterize ‘Youth and Family Ministry’ make such hearing possible? Here, literature delineating ‘Youth and Family Ministry’ is analyzed in light of its biblical foundations. The primary lens implemented in this analysis is the law/gospel hermeneutic advocated by Martin Luther and other reformers.     

Extremes of self-esteem and narcissism and the experience and expression of anger and aggression

This study examined the level of self-esteem and narcissism as personality variables involved in the disposition to experience and express anger. Three hundred thirty-eight subjects were sampled across two higher education centres and one student teaching programme in the United Kingdom. It was reasoned that individuals with both high self-esteem and narcissism would report especially high tendencies to experience and express anger and aggression and that those with high self-esteem and low narcissism would report the lowest. These predictions were influenced by theories that emphasise the role of threats to high self-esteem in the production of aggression and violence. Results indicate that groups defined by their extreme scores on self-esteem and narcissism scales produced levels of anger expression in the predicted direction. The importance of considering extreme levels of self-esteem and narcissism (in conjunction with other factors) in an analysis of anger is discussed with reference to currently influential theories in the field.

Dance and psychotherapy--possibilities and limits

From a starting point of therapeutic and prophylactic components identifiable in the dance, the authors regard the dance as deserving of greater attention than was hitherto the case in programs of physiotherapy, psychotherapy, and sociotherapy. From the existing essays at a therapy basing on body and motion, they infer basic common points, and to promote discussion, they state their attitudes in respect of the potential and rank of the dance in the concept of complex multimodal psychotherapy.     

Yin and Yang,and the Hot and the Cold

Yin and Yang are important concepts in ancient Chinese philosophy.Western scholars have become more familiar with these two concepts recently,but for a long time almost no one considered comparing them with their own tradition such as the ancient Greek philosophy,and especially with the ideas of the Hot and the Cold in Presocratic philosophy.In this paper,I make an attempt to do exactly that,and especially make a detailed comparison between the thoughts of two ancient thinkers:Laozi and Anaximander.I discuss the thought of Yin and Yang in Laozi-who was the earliest philosopher making use of the concepts Yin and Yang-to express his cosmological thought in ancient Chinese philosophy.Comparatively,I discuss the ideas of the Hot and the Cold in Anaximander,the earlier among Presocratic philosophers referring to the Hot and the Cold as fundamental concepts used to establish his cosmological system.Through this comparison,I indicate that the similarity between ancient Chinese and Western traditions is far more significant than what people are used to imagining.     

Perversion and infancy and adolescence

Abstract

Studying the works of Freud and Lacan, the authors carried out research on perversion in childhood. Their work covered the perverse polymorphism of infantile sexuality and the perception of the anatomic difference between the sexes that leads the child to create sexual theories and fantasies. The phallic mother and the fetish are viewed as imaginary solutions directly related to the Oedipus and castration complexes. In perversion, a particular position is taken in relation to the Oedipus complex: a serious flaw occurs in the symbolization of the law, and the mechanisms of denial and disavowal take form. Sexuality requires a second “logical time,” separated from infancy by the latency period, in order to confirm (in action) that a fixed position of jouissance (enjoyment) has actually been established. This can only happen in a period after adolescent enhancement. The distinction between perverse traces and a perverse structure is made, taking into account the fact that, in the case of child analysis, the analyst should free the child from the family fantasy and help him/her to build his/her own fantasy.

Campos Santoro V. et al. Perversion und Kindheit und Adoleszenz.

Im Studium der Arbeiten von Freud und Lacan haben die Autoren Forschung über Perversion in der Kindheit gemacht. Die Studien behandeln den perversen Polymorphismus der infantilen Sexualität und die Wahrnehmung des anatomischen Unterschiedes zwischen den Geschlechtern, welche das Kind dazu führt, Sexual-Theorien und Phatasien zu schaffen.

Die phallische Mutter und der Fetisch werden als imaginäre Lösungen angesehen, die sich direkt auf den Ödipus- und Kastrations-Komplex beziehen. Bei der Perversion wird eine besondere Position in Bezug auf den Ödipus angenommen; ein ernsthafter Mangel tritt bei der Symbolisierung des Rechts auf; die Mechanismen der Verneinung und der Verleugnung bilden sich. Sexualität erfordert eine zweite “logische Zeit”, von der Kindheit durch die Latenz Periode getrennt, um (in der Handlung) zu bestätigen, daß eine fixierte Position der jouissance (Vergnügung) sich tatsächlich etabliert hat. Das kann sich nur in einer Periode nach der adoleszenten Verstärkung ereignen.

Es wird die Unterscheidung zwischen perversen Spuren und einer perversen Struktur gemacht, in Rechnung stellend, daß im Fall der Kinder-Analyse der Analytiker das Kind von der Familien-Phantasie befreien sollte und ihm/ihr helfen sollte, seine/ihre Phantasie auszubilden.

Campos Santoro V. Perversión e infancia y adolescencia.

Estudiando los trabajos de Freud y Lacan, los autores han investigado la perversión en la niñez. Los estudios cubren la sexualidad infantil perversa polimorfa y la percepción de la diferencia anatómica entre los sexos, que llevan al niño a crear teorías sexuales y fantasías.

La madre fálica y el fetiche son vistos como soluciones imaginarias relacionadas directamente con el complejo de Edipo y de castración. La perversión, toma una posición particular en relación al Edipo; un fallo importante tiene lugar en la simbolización de la ley; los mecanismos de negación y repudio toman forma. La sexualidad requiere un segundo “tiempo lógico” separado de la infancia por el periodo de latencia, para confirmar (en acto) que una posición fija de jouissance (goce) se ha establecido. Esto solo puede ocurrir en un periodo posterior a la intensificación adolescente.

La distinción entre las huellas perversas y la estructura perversa se ha hecho, teniendo en cuenta que, en el caso del análisis de niños, el analista debe librar al niño de la fantasía familiar y ayudar a el/ella a construir su propia fantasía.     

神圣、凡俗与净明、忠孝

本文结合有关宗教学理论,对宋元净明道所推崇的"净明"、"忠孝"概念进行了解析.作者以为:宋元净明道视世俗性的道德实践为"神圣"的宗教修炼,实与宗教学中的凡俗可以"转换"为神圣之理论相合;而净明道徒的这种"转换",则多与其个体的"宗教体验"有关.至于元代净明道借"无极"概念来释"净明",以"净明"为回复宇宙根源之境界,则合于宗教人经验到与万物的根源、终极的本体或神圣的世界契合之感.换言之,宋元净明道的"净明"、"忠孝"说,实与各种宗教的本质有着相通之处.
