项目诊断性在特征推理中作用的研究

该研究在Murphy等人2005年研究的基础上,探讨了项目诊断性对特征推理的影响。实验1探讨归类情况下,项目诊断性对特征推理的影响。实验2探讨不归类情况下,项目诊断性对特征推理的影响。实验结果表明,归类与否决定项目诊断性是否影响特征推理。在归类情况下,高低两种诊断性条件下的特征概率判断没有差异,表明归类情况下,项目诊断性不影响特征推理;在不归类的情况下,高低两种诊断性条件下的特征概率判断存在显著差异,表明不归类情况下,项目诊断性影响特征推理。

Induction of Relational Schemas: Common Processes in Reasoning and Complex Learning

Five experiments were performed to test whether participants induced a coherent representation of the structure of a task, called a relational schema, from specific instances. Properties of a relational schema include: An explicit symbol for a relation, a binding that preserves the truth of a relation, potential for higher-order relations, omnidirectional access, potential for transfer between isomorphs, and ability to predict unseen items in isomorphic problems. However relational schemas are not necessarily coded in abstract form. Predictions from relational schema theory were contrasted with predictions from configural learning and other nonstructural theories in five experiments in which participants were taught a structure comprised of a set of initial-state,operator → end-state instances. The initial-state,operator pairs were presented and participants had to predict the correct end-state. Induction of a relational schema was achieved efficiently by adult participants as indicated by ability to predict items of a new isomorphic problem. The relational schemas induced showed the omnidirectional access property, there was efficient transfer to isomorphs, and structural coherence had a powerful effect on learning. The “learning to learn” effect traditionally associated with the learning set literature was observed, and the long-standing enigma of learning set acquisition is explained by a model composed of relational schema induction and structure mapping. Performance was better after reversal of operators than after shift to an alternate structure, even though the latter entailed more overlap with previously learned tasks in terms of the number of configural associations that were preserved. An explanation for the reversal shift phenomenon in terms of induction and mapping of a relational schema is proposed. The five experiments provided evidence supporting predictions from relational schema theory, and no evidence was found for configural or nonstructural learning theories.

A Draft for Unifying Controversies in Philosophy of Science

The basic (negative and positive) methodological maxims of three currents of philosophy of science (logical empiricism, falsificationism, and postpositivism) are formulated. Many of these maxims (stratagems) are controversial, e.g., the stance about the nonsense of metaphysics, and that of its indispensability. The restricted validity of these maxims allows for their unification. Within the framework of most of them there may be a relationship of (synchronic, or diachronic) subordination of the contradicting desiderata. In this vein ten stratagems are formulated.

关于医学哲学逻辑起点的思考——兼与刘虹教授商榷

人的生命存在在医学哲学理论体系中具有最抽象、最简单、最根本的规定性。医学哲学的其它概念都是人的生命存在的逻辑展开和转化。同时,人的生命存在是人的健康的先决条件,而健康只是人的生命存在的一种样态。因之,医学哲学应以人的生命存在作为其逻辑起点。     

Identical Twins,Deduction Theorems,and Pattern Functions: Exploring the Implicative BCSK Fragment of S5

We recapitulate (Section 1) some basic details of the system of implicative BCSK logic, which has two primitive binary implicational connectives, and which can be viewed as a certain fragment of the modal logic S5. From this modal perspective we review (Section 2) some results according to which the pure sublogic in either of these connectives (i.e., each considered without the other) is an exact replica of the material implication fragment of classical propositional logic. In Sections 3 and 5 we show that for the pure logic of one of these implicational connectives two – in general distinct – consequence relations (global and local) definable in the Kripke semantics for modal logic turn out to coincide, though this is not so for the pure logic of the other connective, and that there is an intimate relation between formulas constructed by means of the former connective and the local consequence relation. (Corollary 5.8. This, as we show in an Appendix, is connected to the fact that the ‘propositional operations’ associated with both of our implicational connectives are close to being what R. Quackenbush has called pattern functions.) Between these discussions Section 4 examines some of the replacement-of-equivalents properties of the two connectives, relative to these consequence relations, and Section 6 closes with some observations about the metaphor of identical twins as applied to such pairs of connectives.     

Change mechanisms in cognitive therapy of a simple phobia: Logical analysis and empirical hypothesis testing

The effectiveness of two hypothesized change mechanisms in cognitive therapy was investigated: logical analysis and empirical hypothesis testing. Thirty-eight spider phobics, as determined by performance on a behavioral avoidance test, were randomly assigned to either one of these two conditions or to a no-treatment control condition. Subjects participated in three group sessions. Outcome phobia questionnaire data suggested that both mechanisms produced desirable changes in a short period of time, with stronger evidence that logical analysis was superior to the control. Outcome from the behavior avoidance test and self-efficacy ratings failed to reach statistical significance but the trends were in the direction of positive change. Results are discussed in terms of the tripartite response dessynchrony hypothesis.

The Organization of Justificatory Discourse in Interaction: A Comparison Within and Across Cultures

Previous scholarship has focused on inductive and deductive patterns as the two predominant modes of reasoning. In this paper, we argue that there are many ways that people from diverse cultures organize their justificatory reasoning in conversation with others and that these patterns are connected, in part, to cultural beliefs and values. We report on a study of people who identify themselves as being in one of four cultural groups: African Americans, Asian Americans, Asians, and European Americans. The types of organization they used in their conversations included deductive, inductive, abductive, and narrative patterns. Abduction occurred as often as induction and deduction across groups. Narratives were used equally by all of the groups, but they occurred less frequently than the other types. Asian Americans used inductive patterns more than other types, and Asians were most likely to reason deductively. These choices did not appear to have an effect on partners' judgments, although Asians received the lowest appropriateness ratings, and both Asians and Asian Americans were given the lowest effectiveness ratings.     

Making Room at the Table: Lutheran Ministry in a Religiously Plural America

Religious pluralism is a part of the American experience. This article proposes that Christianity in the United States is not under attack, as some claim, but that such religiosity has been a part of the American experience from the very beginning. Such diversity is now more public and acceptable. This reality requires clergy and lay leaders to develop skills to help their congregations navigate their ongoing multi‐faith relationships within families, at work, school, and within civic organizations. The article argues that Christian faithfulness is not a matter of changing what we believe in response to religious pluralism, but how we articulate our beliefs in such a context. Finally, the author proposes several practical guidelines for developing such pastoral skills through the use of Luther's Catechisms.     

Contemporary Philosophy of Science in Italy: An Overview

The paper analyses the development of some themes in the contemporary philosophy of science in Italy. Section 1 reviews the dabate on the legacy of neopositivism. The spread of the philosophy of Popper is outlined in Section 2, with particular regard to the problem of the vindication of induction. Section 3 deals with the debate on the incommensurability thesis, while Section 4 examines its consequences on the possible relationships between historical and epistemological studies of science. The last section is devoted to one of the most recent trends in the Italian philosophy of science: the resumption of Aristotelian dialectics.

对妊娠晚期畸形胎儿实施致死性引产的可行性分析

在妊娠晚期发现胎儿畸形,许多胎儿父母要求引产。一些患儿父母因为在医院引产出活体畸形婴儿而与医院产生纠纷。本文考虑采用医疗方法在引产前或引产中使胎儿心跳停止,确保引产出的胎儿为死婴（即致死性引产）以减少纠纷,利于社会。本文试图从医疗、伦理、法律的角度,探讨在胎儿父母要求下,对妊娠晚期畸形胎儿实施致死性引产的可行性。     

Rawls and Religious Community: Ethical Decision Making in the Public Square

While most people may initially agree that justice is fairness,as an evangelical Protestant I argue that, for many religiouscomprehensive doctrines, the Rawlsean model does not possessthe resources necessary to sustain tolerance in moral decisionmaking. The weakness of Rawls's model centers on the reasonablepriority of convictions that arise from private comprehensivedoctrines. To attain a free and pluralistic society, peopleneed resources sufficient to provide reasons to tolerate actionsthat are otherwise intolerable. In addition to arguing for thedeficiency of the Rawlsean political model, I sketch out a preliminarymodel of ambassadorship that offers religious communities, andin particular Protestant evangelicals, the necessary resourcesto engage the broader society tolerantly while maintaining theirreligious convictions. As a citizen of the church and a memberof another kingdom, Christians serve as ambassadors to thosewho are not of the heavenly kingdom. I take this model to bemore ambitious than that of a sojourner who lives in the landbut is isolated as much as possible from society, while moremodest than that of reconstructionists who seek to implementtheir own sacred law on all others.     

脑的逻辑功能的核磁共振成像及其哲学意义

国际上关于逻辑对应的脑物理特征的功能核磁共振成像（fMRI）研究的主要成就在于：建立了高级精神活动和低级神经活动的关联关系的试验方法;提出了高级精神活动的（判断和推理）神经计算模型建立方法。这些研究的实验结果表明,逻辑与神经活动具有确定性的对应关系,它证明了强人工智能的观点：导致意识的可验证的实体（或者称为“意识关联物”）就是意识本身。意识的运行方式是可计算的,思维的本质可以还原为机械性的操作步骤,人工智能和人的天然智能在本质上并无二致。     

Making the uncontrollable seem controllable: The role of action in the illusion of control

It is well known that certain variables can bias judgements about the perceived contingency between an action and an outcome, making them depart from the normative predictions. For instance, previous studies have proven that the activity level or probability of responding, P(R), is a crucial variable that can affect these judgements in objectively noncontingent situations. A possible account for the P(R) effect is based on the differential exposure to actual contingencies during the training phase, which is in turn presumably produced by individual differences in participants' P(R). The current two experiments replicate the P(R) effect in a free-response paradigm, and show that participants' judgements are better predicted by P(R) than by the actual contingency to which they expose themselves. Besides, both experiments converge with previous empirical data, showing a persistent bias that does not vanish as training proceeds. These findings contrast with the preasymptotic and transitory effect predicted by several theoretical models.     

Making the illusory correlation effect appear and then disappear: The effects of increased learning

The acquisition of a negative evaluation of a fictitious minority social group in spite of the absence of any objective correlation between group membership and negative behaviours was described by Hamilton and Gifford (1976) Hamilton, D. L. and Gifford, R. K. 1976. Illusory correlation in intergroup perception: A cognitive basis of stereotypic judgments. Journal of Experimental Social Psychology, 12: 392–407. [Crossref], [Web of Science ®] , [Google Scholar] as an instance of an illusory correlation. We studied the acquisition and attenuation through time of this correlation learning effect. In two experiments we asked for participants’ judgements of two fictitious groups using an online version of a group membership belief paradigm. We tested how judgements of the two groups changed as a function of the amount of training they received. Results suggest that the perception of the illusory correlation effect is initially absent, emerges with intermediate amounts of absolute experience, but diminishes and is eliminated with increased experience. This illusory correlation effect can be considered to reflect incomplete learning rather than a bias due to information loss in judgements or distinctiveness.     

The Need for a Revolution in the Philosophy of Science

There is a need to bring about a revolution in the philosophy of science, interpreted to be both the academic discipline, and the official view of the aims and methods of science upheld by the scientific community. At present both are dominated by the view that in science theories are chosen on the basis of empirical considerations alone, nothing being permanently accepted as a part of scientific knowledge independently of evidence. Biasing choice of theory in the direction of simplicity, unity or explanatory power does not permanently commit science to the thesis that nature is simple or unified. This current ‘paradigm’ is, I argue, untenable. We need a new paradigm, which acknowledges that science makes a hierarchy of metaphysical assumptions concerning the comprehensibility and knowability of the universe, theories being chosen partly on the basis of compatibility with these assumptions. Eleven arguments are given for favouring this new ‘paradigm’ over the current one. This revised version was published online in August 2006 with corrections to the Cover Date.
