Pluralism and Ambivalence in the Evolution of Morality

Much good work has been done on the evolution of human morality by focusing on how “selfish genes” can give rise to altruistic human beings. A richer research program is needed, however, to take into account the ambivalence of naturally evolved biopsychological motivators and the historical pluralism of human morality in religious systems. Such a program is described here. A first step is to distinguish the ultimate cause of natural selection from proximate causes that are the results of natural selection. Next, some proximate causes are suggested as possible conditions of biological and emotional valuing as well as of customary social morality and individual rational ethical thought. Finally, different moral perspectives of Confucianism, Hinduism, Buddhism, and Christianity are briefly presented in order to illustrate how one might inquire about the selection of a variety of biopsychological and cultural proximate causes that enable the evolution of a plurality of religious moral systems.     

表面内容不同方面相似性对样例迁移的影响

应用题表面内容分离为表面概貌和对象对应后,还可以进行再分解。本实验将表面概貌分解为具体属性和问题形式,将对象对应分解表述顺序对应和具体对象对应,研究结果表明,表面内容不同方面的相似性对原理运用有不同的影响。     

现代医学人文回归的学术性与现实性

以生物-心理-社会医学模式为背景,以哲学和生态审美理论为起点,提出了"医学人文精神"、"医学人文关怀"等概念,在此基础上,分析了医学人文回归的内容及其与医学审美之间的内在联系.从学术性和现实性两个层面,针对我国存在的医学人文缺失的现状,分析了以"三观"(生命观、健康的可持续发展观、科学观)为基础的人文信仰的内容、功能与意义,以及如何从内容与形式辩证统一的审美视角出发,运用美的规律去改善、丰富和提升医学人文关怀的境界.     

视知觉无意识加工中的形状优势效应

研究了视知觉无意识加工中是否存在形状优势效应。被试为天津师范大学本科生60名。仪器为pentium lll高分辨率计算机．程序用E-prime心理实验软件系统编制而成。在实验1中,用信号检测论技术发现．当启动图形呈现时间为20ms时．被试是不能觉知到该图形的。在实验2和3中．被试的任务分别是判断图形的形状和颜色,用MANOVA分析启动图形对靶图形的启动效应时发现．启动图形的颜色线索不会影响靶图形的形状判断,但启动图形的形状线索却能抑制或促进靶图形的颜色判断。实验证据提示．在判断物体整体特征时,无意识知觉具有形状优势效应。     

论心理学发展的困境与出路

近年来西方心理学家对心理学发展取向提出强烈批评。综合各家所论,心理学以往发展的困境乃是由于：(1)自哲学心理学到科学心理学对人性解释的理论始终纷歧,以致无法形成常规科学条件;(2)科学心理学自始即标榜自然科学而缺独立意识;(3)强调科学方法,忽视人性特质而陷入削足适履困境。因此,今后国内心理学的发展势不能再全盘西化,而应在人性特质与本土文化基础上吸取西方心理学精义,针对国人心理特质研究发展出属於自己的理论与应用心理学。本文最后提出的四会能力教学构想,希望对本土文化取向应用心理学的研究发挥一点抛砖引玉作用。     

论医学人文精神的历史走向

医学人文精神和医学科学精神的整合交融,是医学走向成熟的标志,对生命的终极关怀,是医学人文精神的基本内涵;对医患关系的理解和介入方式,是医学人文精神切入实践的关键;医学人文品格是医学人文精神的良性载体和职业表征。是医生理想的职业人格。这四个问题从不同角度,不同层面凸现了医学人文精神的实质,反映了在新医学模式背景下医学人文精神的历史走向。     

Is knowledge a natural kind?

The project of treating knowledge as an empirical object of study has gained popularity in recent naturalistic epistemology. It is argued here that the assumption that such an object of study exists is in tension with other central elements of naturalistic philosophy. Two hypotheses are considered. In the first, “knowledge” is hypothesized to refer to mental states causally responsible for the behaviour of cognitive agents. Here, the relational character of truth creates a problem. In the second hypothesis “knowledge” is hypothesized to refer to mental states causally responsible for the evolutionarily successful behaviour of cognitive agents. Here, the problem lies in the fact that evolution by natural selection is not necessarily conducive to truth. The result does not necessarily amount to eliminativism, however, since the naturalist may consistently reject the condition of truth that lies behind these problems.     

Autoshaping the pigeon's gape response: acquisition and topography as a function of reinforcer type and magnitude.

The pigeon's key-pecking response is experimentally dissociable into transport (head movement) and gape (jaw movement) components. During conditioning of the key-pecking response, both components come under the control of the conditioned stimulus. To study the acquisition of gape conditioned responses and to clarify the contribution of unconditioned stimulus (reinforcer) variables to the form of the response, gape and key-contact responses were recorded during an autoshaping procedure and reinforcer properties were systematically varied. One group of 8 pigeons was food deprived and subgroups of 2 birds each were exposed to four different pellet sizes as reinforcers, each reinforcer signaled by a keylight conditioned stimulus. A second group was water deprived and received water reinforcers paired with the conditioned stimulus. Water- or food-deprived control groups received appropriate water or food reinforcers that were randomly delivered with respect to the keylight stimulus. Acquisition of the conditioned gape response frequently preceded key-contact responses, and gape conditioned responses were generally elicited at higher rates than were key contacts. The form of the conditioned gape was similar to, but not identical with, the form of the unconditioned gape. The gape component is a critical topographical feature of the conditioned key peck, a sensitive measure of conditioning during autoshaping, and an important source of the observed similarities in the form of conditioned and consummatory responses.
