不同概念范畴和特征类别对儿童归纳推理多样性效应的影响

为探讨概念范畴和特征类别对归纳推理多样性效应的影响, 采用2(概念范畴: 生物类别与非生物类别)´2(特征类别: 不可见的隐蔽特征和可见的外显特征)的实验设计, 设计了四组任务来考察5~6岁、8~9岁儿童归纳推理多样性效应的表现水平。结果显示: 在非生物类别范畴材料上, 5~6岁儿童在两种特征类别上均未表现出多样性效应, 8~9岁儿童在隐蔽特征类别上表现出多样性效应; 在生物类别材料上, 5~6岁、8~9岁儿童在外显特征和隐蔽特征上均未表现出多样性效应。概念范畴和特征类别对8~9岁儿童的归纳判断力有显著影响: 在概念范畴上, 儿童在非生物范畴材料上的表现显著高于生物范畴; 在特征类别上, 儿童在隐蔽特征上的表现高于外显特征。     

归纳推理属性效应中背景关系提取原则的探究

本实验以生态关系、类别关系和无关三类项目为推理背景, 以基因X和疾病Y为不同的推理属性, 通过考察实验材料快速或延迟呈现时对推理可能性和推理信心的影响来探究属性效应中背景关系提取的原则。结果发现实验材料快速和延迟呈现时对推理可能性无显著影响, 但对推理信心有显著影响, 快速呈现时被试的推理信心显著高于延迟呈现时。由此可以认为归纳推理属性效应中人们优先按照相关性原则提取背景关系, 同时该结果还表明属性效应既有跨文化的普遍性也有其文化特殊性。     

AI,ME AND LEWIS (ABELIAN IMPLICATION,MATERIAL EQUIVALENCE AND C I LEWIS 1920)

C I Lewis showed up Down Under in 2005, in e-mails initiated by Allen Hazen of Melbourne. Their topic was the system Hazen called FL (a Funny Logic), axiomatized in passing in Lewis 1921. I show that FL is the system MEN of material equivalence with negation. But negation plays no special role in MEN. Symbolizing equivalence with → and defining ∼A inferentially as A→f, the theorems of MEN are just those of the underlying theory ME of pure material equivalence. This accords with the treatment of negation in the Abelian l-group logic A of Meyer and Slaney (Abelian logic. Abstract, Journal of Symbolic Logic 46, 425–426, 1981), which also defines ∼A inferentially with no special conditions on f. The paper then concentrates on the pure implicational part AI of A, the simple logic of Abelian groups. The integers Z were known to be characteristic for AI, with every non-theorem B refutable mod some Zn for finite n. Noted here is that AI is pre-tabular, having the Scroggs property that every proper extension SI of AI, closed under substitution and detachment, has some finite Zn as its characteristic matrix. In particular FL is the extension for which n = 2 (Lewis, The structure of logic and its relation to other systems. The Journal of Philosophy 18, 505–516, 1921; Meyer and Slaney, Abelian logic. Abstract. Journal of Symbolic Logic 46, 425–426, 1981; This is an abstract of the much longer paper finally published in 1989 in G. G. Priest, R. Routley and J. Norman, eds., Paraconsistent logic: essays on the inconsistent, Philosophica Verlag, Munich, pp. 245–288, 1989). Meyer was supported in this work as a Visiting Fellow in the College of Engineering and Computer Science, ANU.     

Randomness,Contingency, and Faith: Is there a Science of Subjectivity?

Materialists argue that there is no place for God in the universe. Chance and contingency are all that structure our world. However, the materialists’ dismissal of subjectivity manifests a flawed metaphysics that invalidates their arguments against God. In this essay I explore the following: (1) How does personal metaphysics affect one's ability to do science? (2) Are the materialist arguments about contingency used to dismiss the importance of our place in the universe valid? (3) What are the implications of subjectivity on belief and science? To answer the first question, I examine the later years of Sir Alfred Russel Wallace, one of the cofounders of evolution through natural selection with Darwin. His belief in nineteenth–century spiritualism profoundly affected his standing in the scientific community. I describe the effect of spiritualism on Wallace's science. To answer the second question, I use my own work in mathematical modeling of evolutionary processes to show that randomness, and contingency at one level, can actually be nearly deterministic at another. I demonstrate how arguments about chance and contingency do not imply anything relevant about whether there is a designer behind the universe. To answer the third question I begin by exploring a paradox of consciousness and show how the existence of subjective truths may provide a paradigm for sustaining a rational belief in God. These questions form the framework of a structured belief in a creator while yet embracing what science has to offer about the development of life on our planet.     

呈现时间与词的属性对记得和知道判断的影响

本研究探讨记得与知道反应的特点及机制。两个实验分别以具体或抽象名词、情绪色彩不同的形容词作为测验材料,呈现不同时间。结果发现呈现时间与词的属性都引起记得和知道判断上的实验性分离,表明对信息源不同意识水平的监控受信息呈现时间和信息属性的影响。研究支持解释记得与知道机制的双加工理论,本文也讨论了两种机制可能共同起作用的看法。     

Some Weakened Gödelian Ontological Systems

We describe a KB Gödelian ontological system, and some other weak systems, in a fully formal way using theory of types and natural deduction, and present a completeness proof in its main and specific parts. We technically and philosophically analyze and comment on the systems (mainly with respect to the relativism of values) and include a sketch of some connected aspects of Gödel's relation to Kant.     

中文新异组合概念的解释及影响因素

通过分析600名中国大学生对32个概念组成的160个新异组合概念的解释,考察了中文名词-名词组合概念的解释策略及影响因素。结果表明：⑴关系解释和属性解释是两种主要的解释策略;⑵第一个子概念具有显著属性的组合概念得到更多的属性解释;⑶子概念之间相似性的高低不影响属性解释出现的比率,但影响关系解释出现的比率;⑷生物组合概念比人造物组合概念得到更多的属性解释。其中的新发现既不支持关系竞争理论,也不支持双重加工理论,引出了有待研究的新问题。     

On the Compositional Extension Problem

A semantics may be compositional and yet partial, in the sense that not all well-formed expressions are assigned meanings by it. Examples come from both natural and formal languages. When can such a semantics be extended to a total one, preserving compositionality? This sort of extension problem was formulated by Hodges, and solved there in a particular case, in which the total extension respects a precise version of the fregean dictum that the meaning of an expression is the contribution it makes to the meanings of complex phrases of which it is a part. Hodges' result presupposes the so-called Husserl property, which says roughly that synonymous expressions must have the same category. Here I solve a different version of the compositional extension problem, corresponding to another type of linguistic situation in which we only have a partial semantics, and without assuming the Husserl property. I also briefly compare Hodges' framework for grammars in terms of partial algebras with more familiar ones, going back to Montague, which use many-sorted algebras instead.

视知觉组织在整体知觉中的作用--脑损伤病人的实验研究

本实验研究大脑损伤如何影响复合图形的整体知觉。三例病人脑损伤部位分别在大脑枕区、顶区、颞区、额区及基底节和豆状核。复合图形被呈现给病人和正常对照被试。强迫选择识别等任务表明,当空间相邻性决定局部图形的知觉组织时,病人识别整体性质的正确率高于(ZD和FL)或略底于(GK)识别局部性质的正确率;当形状相似性决定局部图形的知觉组织时,病人识别整体性质的正确率显著降低,而识别局部性质的正确率受到的影响较小。在同样的任务中正常被试识别整体和局部性质的正确率受知觉组织因素的影响很小。这些结果提示大脑损伤对整体知觉的破坏可能主要通过影响基于形状相似性的知觉组织实现。
