人性观对心理学理论与研究的影响 总被引:5,自引:0,他引:5
心理学的基本理论,尤其是人格理论,通常都蕴含着对人性的假设。人性观的差异常常导致其理论建构的差异。而且人性观影响心理学研究的方式、方法,影响对心理成因的认识、对心理疾病的理解、及对异常矫正策略的选择。 相似文献

This paper is a response to particularist critics of the normative force of moral principles. The particularist critique, as I understand it, is a rejection not only of principle-based accounts of moral deliberation and justification, but also of accounts of character in which principles play a central role. I focus on the latter challenge and counter it with a view I call character-principlism .
I begin by discussing in a general way what motivates the particularity objection to principles and then contrast two views – both of which insist on the importance of attentiveness to particularity – about the relative normative status of principles and particular cases. I present some reasons for believing that we need a more normatively robust conception of the role of moral principles than the particularists provide. In the main portion of the paper, I discuss how character-principlism sees principles functioning in our lives and the lives we lead with others. I contrast this with some other accounts of desirable character that particularists can embrace, and argue that these are seriously flawed because, unlike character-principlism, they cannot satisfactorily explain how a person could possess the constancy of character that moral integrity requires. 相似文献

This paper discusses two forms of separability of item and person parameters in the context of response time (RT) models. The first is separate sufficiency: the existence of sufficient statistics for the item (person) parameters that do not depend on the person (item) parameters. The second is ranking independence: the likelihood of the item (person) ranking with respect to RTs does not depend on the person (item) parameters. For each form a theorem stating sufficient conditions, is proved. The two forms of separability are shown to include several (special cases of) models from psychometric and biometric literature. Ranking independence imposes no restrictions on the general distribution form, but on its parametrization. An estimation procedure based upon ranks and pseudolikelihood theory is discussed, as well as the relation of ranking independence to the concept of double monotonicity.I am indebted to Wim van der Linden for bringing Thissen's (1983) paper to my notice, and to Martijn Berger, Frans Tan, and the anonymous reviewers for their constructive comments on earlier drafts of this paper. 相似文献

This paper investigates partitions of lattices of modal logics based on superintuitionistic logics which are defined by forming, for each superintuitionistic logic L and classical modal logic , the set L[] of L-companions of . Here L[] consists of those modal logics whose non-modal fragments coincide with L and which axiomatize if the law of excluded middle p V p is added. Questions addressed are, for instance, whether there exist logics with the disjunction property in L[], whether L[] contains a smallest element, and whether L[] contains lower covers of . Positive solutions as concerns the last question show that there are (uncountably many) superclean modal logics based on intuitionistic logic in the sense of Vakarelov [28]. Thus a number of problems stated in [28] are solved. As a technical tool the paper develops the splitting technique for lattices of modal logics based on superintuitionistic logics and ap plies duality theory from [34]. 相似文献

Propositional and notional attitudes are construed as relations (-in-intension) between individuals and constructions (rather than propositrions etc,). The apparatus of transparent intensional logic (Tichy) is applied to derive two rules that make it possible to export existential quantifiers without conceiving attitudes as relations to expressions (sententialism). 相似文献

6 15岁儿童对友谊特性的认知发展 总被引:10,自引:0,他引:10
研究目的:(1)考察我国儿童、青少年的友谊特性的认知发展规律和特点;(2)探讨儿童友谊特性的认知结构。研究采用结构访谈法,被试为来自北京市普通幼儿园、小学和中学的6岁、8岁、10岁、12岁和15岁儿童共100名(每个年龄组20名,男女各半)。结果发现:(1)6—15岁儿童对友谊特性的认知结构由5个维度组成,即:个人交流和冲突解决,榜样和竞争,互相欣赏,共同活动和互相帮助,亲密交往。(2)对6—15岁儿童,友谊特性中的5个维度的重要性次序为:共同活动和互相帮助,个人交流和冲突解决,榜样和竞争,互相欣赏,亲密交往。(3)从发展上来看,对友谊特性不同维度的认知发展趋势有很大年龄差异。6—8岁儿童只能认识到友谊特性中一些外在的、行为的特征;以后才能逐渐认识到那些内在的、情感性的特征。但是,原来那些外在的特征并没有随着儿童年龄的增长而被取代,而是与内在的、情感性的特性结合在一起,在认识中逐渐深化。(4)小学六年级儿童在共同活动和游戏上表现出性别差异(男生高于女生);而在冲突解决上,女生的认知水平高于男生。此外,初中三年级学生在互相欣赏方面,男生的认识水平高于女生 相似文献

From antiquity to the present, humans have debated whether intelligent life exists elsewhere in the universe. This presentation will survey this debate, examining the roles played in it by science, religion, philosophy, and other areas of human learning. One thesis that will be developed is that whether or not extraterrestrials exist, ideas about them have strongly influenced Western thought. 相似文献

Does God have a mind? Western theism has traditionally construed God as an intentional agent who acts on creation and in relation to humankind. God loves, punishes, and redeems. God's intentionality has traditionally been construed in analogy to human intentionality, which in turn has often presumed a supernatural dualism. Developments in cognitive science, however, render supernatural dualism suspect for explaining the human mind. How, then, can we speak of the mind of God? Borrowing from Daniel Dennett's intentional stance, I suggest that analogical reasoning regarding the mind of God be abandoned in favor of an ontologically agnostic approach that treats God as an intentional system. In this approach, God's purposive action is an explanatory feature of the believer's universe, a real pattern that informs our values and beliefs about the world and our place in it. 相似文献
