No Time of Day Modulation or Time Stamp on Multiple Memory Tasks in Rats

Various demonstrations of “time stamp” effects in the animal learning literature have reinforced the idea that circadian information is encoded as part of a combined internal/external representation of context and that this contextual information is utilized for complex retrieval processes supporting memory. The goal of the present series of experiments is to assess this idea by manipulating training/testing circadian times on a battery of learning and memory tasks commonly used in the rodent. The data obtained from five experiments using four different learning and memory paradigms provide no evidence for “time stamp” effects on place memory, context memory (aversive or appetitive), or S-R habit learning.     

创造性的生理研究新进展

创造性的生理基础很复杂。关于创造性生理基础的研究集中在大脑皮质激活与脑半球不对称两个方面。研究发现,大脑皮质激活状态对创造性有影响,低水平的皮质激活,特别是低水平的前额叶激活,较有利于创造性．研究还发现,创造性和左右半球不对称活动有关,处于创造状态时,右半球相对要比左半球激活程度更高。     

Cloninger's Temperament and Character Inventory Correlates with Personality Characteristics of Organ Donation Advocates

Temperament and Character Inventory (TCI) and background questionnaire data were collected from a sample of men and women organ donation advocates (N = 362) as part of a national study to investigate their personality characteristics, temperaments, and attitudes about organ donation advocacy. Goals included identifying unique traits for advocates, and response consistency between the TCI and questionnaire. The TCI results included high scores on Cooperativeness and Self-Directedness, and low on Harm Avoidance dimensions. The questionnaire results indicated that most advocates were White, married, college-educated females, who typically spent less than 2 hr with potential donor families, were satisfied with life and job, and believed they would be in a donation position 2 years from the time surveyed. TCI and questionnaire measures were correlated for Self-Transcendence and Spirituality, Helpfulness and Job Satisfaction, and Compassion and Identification variables.     

婴儿物理因果感知能力的发展

继Michotte(1963)用两个发生碰撞的小球对成人的物理因果理解进行研究以来,许多研究者使用该碰撞情境对婴儿的物理因果感知进行了一系列的研究,并得出了许多颇有争议的结论。本文结合近几年国外对婴儿物理因果感知能力的相关研究,阐述了婴儿感知简单物理情境中的因果关系能力的发展,评价了用来解释婴儿物理因果感知的模块理论与信息加工理论,以期对婴儿期的物理因果感知有一较全面的了解。     

关于克隆人试验与伦理学的三原则

由于克隆人试验的对象是人的活细胞,不是人的胚胎;并且由于人只能有限地决定自己的未来,根本无法决定自己的出生;同时由于基因诊断和修复有助于新生儿的健康,因而克隆人试验既不会伤害任何人的生命体,也不会侵犯任何可能出现的克隆人的自主权和平等权,进而不会违反伦理学的三原则。     

孔子晚年心志蠡测--并为《莫春篇》作一新解

孔子晚年的心志如何,的确多费猜疑。作者发现其中最主要的关键在于如何对当今留下的史料作恰当的选取与解读而已。本文以《论语》为基准,通过《易传》与《春秋》来了解孔子晚年的思想。对《论语》里自古以来号称难解的《莫春篇》作出新的了解,显豁孔子晚年密契天道的意境,指出这正是孔子志存拨乱,推阐易道,作《春秋》运诸三世之苦心。后世实在不宜再忽视或过度怀疑《孟子·滕文公下》、《史记·孔子世家》及新近出土帛书《易传·要篇》等史料具有呈显孔子晚年思想实况的价值性.     

论基因检测之应用及其ELSI议题的文化意涵

在基因科技的革命性发展过程中,整体社会似乎未能提供一个充分保障研究参与者与科学研究之完整性的机制.以台湾面临基因检测之挑战的经验为例,探讨了伦理、法律与社会意涵(Ethial,Legal and Social Implications,ELSI)研究如何完善规范体制的实务应用需求,并兼顾人权团体所期待的妥善保护研究参与者.     

《金刚经》中的时间和空间

《金刚经》指出,佛陀认为时间不是绝对的,空间也不是绝对的,而且,佛陀的这种非绝对的时间观已被现代宇宙学所证实。但佛陀说的经验世界和超经验世界的“空间”却是重叠的不可区分的,这点又和现代宇宙学认为的宇宙向外爆炸膨胀的观点不同。     

暗室条件下刺激大小、亮度和背景对距离判断的影响

問題在知觉心理学中,距离判断問題是心理学者一直感兴趣的問題,外国学者在这方面曾作过不少研究,积累了一些資料。依梯尔逊和埃姆斯(W. H. Ittelson & A. Jr. Ames)的实驗証明,在減縮綫索的条件下,被試用单眼观察同一距离的三张大小不同的扑克牌(标准的、比标准大一倍的、比标准小一半的),較大的显得近些,較小的远些。依梯尔逊根据一系列的实驗結果作出了这样的結論:观察者对熟知客体的主观的假定大小,是距离
