Basic Infobase Change

Generalisations of theory change involving arbitrary sets of wffs instead of belief sets have become known as base change. In one view, a base should be thought of as providing more structure to its generated belief set, and can be used to determine the theory change operation associated with a base change operation. In this paper we extend a proposal along these lines by Meyer et al. We take an infobase as a finite sequence of wffs, with each element in the sequence being seen as an independently obtained bit of information, and define appropriate infobase change operations. The associated theory change operations satisfy the AGM postulates for theory change. Since an infobase change operation produces a new infobase, it allows for iterated infobase change. We measure iterated infobase change against the postulates proposed by Darwiche et al. and Lehmann.     

Some Closure Properties of Finite Definitions

There is no known syntactic characterization of the class of finite definitions in terms of a set of basic definitions and a set of basic operators under which the class is closed. Furthermore, it is known that the basic propositional operators do not preserve finiteness. In this paper I survey these problems and explore operators that do preserve finiteness. I also show that every definition that uses only unary predicate symbols and equality is bound to be finite.     

Reasoning and normative beliefs: not too sophisticated

Does reasoning to a certain conclusion necessarily involve a normative belief in support of that conclusion? In many recent discussions of the nature of reasoning, such a normative belief condition is rejected. One main objection is that it requires too much conceptual sophistication and thereby excludes certain reasoners, such as small children. I argue that this objection is mistaken. Its advocates overestimate what is necessary for grasping the normative concepts required by the condition, while seriously underestimating the importance of such concepts for our most fundamental agential capacities. Underlying the objection is the observation that normative thoughts do not necessarily cross our minds during reasoning. I show that proponents of the normative belief condition can accommodate this observation by taking the required normative belief to guide the reasoning process and offer a novel account of what such guidance consists in.     

成人在错误信念任务上的表现

考察成人在错误信念(FB)任务上是否存在"知识偏差"效应。实验1重复Birch等的实验程序并未得到与之一致的结果,成人在FB任务上的表现不理想,且无"知识偏差"效应存在。实验2排除琴盒位置及颜色的突出性影响后,结果与实验1相似。成人在FB任务上的不佳表现与成人具有心理理论的事实相悖,说明把通过FB任务作为衡量心理理论的唯一评定标准有待商榷。     

心理理论和语言发展的关系

大量的研究表明心理理论和语言之间存在着密切的关系,但具体关系如何,一直存在争议。文章介绍了心理理论和语言关系的新近研究,着重阐述了目前关于二者关系的两种观点： （1）心理理论和语言发展之间不仅是早期揭示的一般相关关系,而是可能存在着因果关系——或以语言为因,或以心理理论为因;（2）心理理论和语言都受第三种因素影响,如执行功能和生长环境,但这些因素是究竟如何影响心理理论和语言发展的,还需深入探讨。文章最后对该领域今后的研究提出了新的见解和思路,包括对不同语言能力间的比较研究,对二者关系的跨文化研究和毕生取向研究等     

多个视角看自杀

鉴于自杀问题本身的极端复杂性及其深远的负面影响,从元认知、强迫信念、内在狂妄以及选择人生不能4个角度尝试对自杀风险因素进行了探析,并从近端救治需关注早发现及对方痛苦被看见,远端防控应强调生命体验的重要性, 外围工作应加强对死者亲人的抚慰3个方面对自杀防控进行了探究,以期对自杀危机干预提供一些新思路。此外,倡导教育在生命意义救治方面应担负更大职责且一刻不能或缺。关注个体的心理因素,同时重视人的社会属性,综合施策、多方努力,自杀问题定会得到更好解决。

     

COMMENTS ON SIX RESPONSES TO DEMOCRACY AND TRADITION

This paper is a rejoinder to papers by Sabina Lovibond, Nicholas Wolterstorff, Sumner B. Twiss, G. Scott Davis, M. Cathleen Kaveny, and John Kelsay on the author's recent book Democracy and Tradition. The argument covers a host of topics, ranging from epistemology and methodology to human rights, the common law, and Islamic ethics.     

THEORIZING RELIGION AND QUESTIONING THE FUTURE OF ISLAM AND SCIENCE

Will there be any joint future for science and Islam? Although such questions have recently received considerable attention, more basic questions are often ignored. This article aims at addressing some of those more basic questions through exploring the assumptions that underlie different possible understandings of the question about the future of Islam and science. By investigating the relation between conceptualizations of religion and the question about the future of Islam and science, it will be argued that different understandings of the concept of religion (i.e., whether it denotes real objects, whether it is universal, and whether it is belief centered) lead to extremely different readings of the question. Besides, it will be argued that different answers to the question about the future of Islam and science can be understood in terms of the inference to best theological explanation; thus, the criteria that one assumes for the best theological explanation result in different criteria for evaluation of the answers.     

父母的经济人信念对自身信任及儿童信任的影响

经济人信念认为人是自私的与理性的,研究者发现,经济人信念会破坏人际信任。然而,以上研究均是以大学生为被试的启动研究,限制了结论的可推广性。本研究编制了经济人信念量表,测量了351名成年被试的经济人信念及他们在投资博弈中的信任水平,以及其子女的信任水平,以考察父母的经济人信念对自身信任和其子女信任的影响。结果发现:(1)研究所编制的经济人信念量表信效度良好;(2)父母和儿童在投资博弈中均表现出了一定水平的信任;(3)父母的经济人信念能够预测其在投资博弈中的信任水平;(4)父母的经济人信念能够预测男孩在投资博弈中的投资额,主要表现为父亲的经济人信念能够负向预测男孩的投资额。     

政策执行偏差严重程度对公众地方政府 责任判断的影响:多重中介模型的检验

为探讨地方政府政策执行偏差严重程度对公众地方政府责任判断的影响机制。采用问卷法对678名社会公众进行调查,结果显示:(1)地方政府政策执行偏差情境下,公众地方政府愿望判断和公众地方政府信念判断在政策执行偏差严重程度和公众地方政府责任判断之间起多重中介作用。(2)公众地方政府信念判断在政策执行偏差严重程度和公众地方政府责任判断之间的中介效应量大于公众地方政府愿望判断的中介效应量。
