表面相似性对数量关系和相对大小关系理解的影响

研究采用数量关系匹配任务和相对大小关系匹配任务,通过高表面相似性、低表面相似性和交叉映射三种实验条件,探讨表面相似性对儿童和成人数量与相对大小关系理解的影响。研究一对37名4岁儿童进行三次每次间隔半年的追踪测查,结果表明4~5岁间儿童理解数量关系和相对大小关系的水平有显著提高;4岁儿童对数量关系的理解受到表面相似性的影响,4~5岁儿童对相对大小关系的理解受到表面相似性的影响。研究二探究44名成人数量和相对大小关系理解的特点,结果发现,成人完成两种关系匹配任务时也受到表面相似性的影响。     

The Relevant Equivalence Property

The pure implicational and the multiplicative fragments of arange of propositional relevant (and other) logics are shownto have the property that any two formulas equivalent in sucha logic are constructed from exactly the same propositionalvariables – as opposed to merely having (as the definitionof relevance itself would require) some propositional variablein common.     

The Neutralist Analysis of Similarity

Philosophia - Consider two similarity facts: a is similar to b with respect to G, and c is similar to d with respect to G. According to the Platonist approach to similarity, the analysis of such...     

The Future Similarity Objection Revisited

David Lewis has long defended an analysis of counterfactuals in terms of comparative similarity of possible worlds. The purpose of this paper is to reevaluate Lewis’s response to one of the oldest and most familiar objections to this proposal, the future similarity objection.     

图形相似比较中的加工模型:特征与结构的作用

本研究采用单一目标映射技术(one-shot mapping)设计实验考察了相似比较中的加工模型。实验结果表明:相似等级的判定对映射任务中结构映射没有显著性影响。相似加工不一定表现为基于结构的加工,基于特征的加工和基于结构的加工是相似加工中两种并行的加工模式。在反应时方面,基于结构的加工的反应时比基于特征的加工的反应时更长。     

面孔部件相似性判断研究

用Morph变形方法构建家族相似性面孔部件样例,采用多级估量法探讨分类活动中面孔部件相似性判断问题。结果发现,部件样例对部件原型的隶属度及部件样例对整体原型中对应部件的隶属度与部件样例变形百分比间是3次函数关系;耳朵、脸型、眼睛等部件样例对整体原型中对应部件的隶属度小于其对部件原型的隶属度,嘴巴样例对整体原型中嘴巴部件的隶属度高于其对部件原型的隶属度。表明面孔部件物理相似性与心理相似性间是3次函数关系;整体原型中其他部件降低了耳朵、脸型、眼睛等部件样例对整体原型中对应部件的隶属度,而提高了嘴巴样例对整体原     

汉语短时序列回忆中的语音相似性和视觉相似性效应

语音相似性效应和视觉相似性效应是短时序列回忆中的两个典型性效应, 但前人很少探讨这两种效应的交互作用。本研究利用汉语字形和语音的属性, 观察汉字短时序列回忆中语音相似性效应、视觉相似性效应及两者的交互作用。研究结果发现当回忆项目在语音或视觉上单纯相似或不相似时, 视觉相似性效应及其与语音相似性的交互作用与混合词表条件下所发现的结果有很大的不同。这个研究结果为丰富和补充相关理论模型提供了进一步实证依据。     

盆腔炎感染的相关因素

盆腔炎是育龄期妇女的常见病和多发病,常见的病原体有细菌、念珠菌、解脲脲原体、沙眼衣原体等.结合临床检测及文献报道,发现年轻女性盆腔炎解脲脲原体感染率较高,是盆腔炎的高发人群.解脲脲原体感染患者合并其他病原微生物感染的情况相当严重.对患者进行全面系统的病原生物检测,对于预防和有效治疗盆腔炎感染十分重要.

The Principle of Summation

The principle of Summation, which is a technically sharpened version of the familiar claim that a whole is a sum of its parts, is presented by Peter van Inwagen as a trivial truth. I argue to the contrary, that it is incompatible with the natural assumption that a whole may gain or lose parts non-instantaneously. For, as I show, the latter assumption implies that something can be determinately a whole without being determinately a sum of parts, and this, in turn, indicates the falsity of Summation. I point out that the tension between Summation and the possibility of non-instantaneous gain or loss of parts compels us to rethink the relations between the concepts of whole and sum, and may have far reaching consequences for the mereology of physical objects.

The Causal Principle

There is a charge sometimes made in metaphysics that particular commitments are ‘hypothetical’, ‘dubious’ or ‘suspicious’. There have been two analyses given of what this consists in—due to Crisp (2007) and Cameron (2011). The aim of this paper is to reject both analyses and thereby show that there is no obvious way to press the objection against said commitments that they are ‘dubious’ and objectionable. Later in the paper I consider another account of what it might be to be ‘dubious’, and argue that this too fails. I use Bigelow's (1996) Lucretian properties as a vehicle for the discussions of dubiousness that follow. As a consequence, the paper ends up offering a partial defense of Lucretianism.     

The Harm Principle

According to the Harm Principle, roughly, the state may coerce a person only if it can thereby prevent harm to others. Clearly, this principle depends crucially on what we understand by harm. Thus, if any sort of negative effect on a person may count as a harm, the Harm Principle will fail to sufficiently protect individual liberty. Therefore, a more subtle concept of harm is needed. I consider various possible conceptions and argue that none gives rise to a plausible version of the Harm Principle. Whether we focus on welfare, quantities of welfare or qualities of welfare, we do not arrive at a plausible version of this principle. Instead, the concept of harm may be moralized. I consider various ways this may be done as well as possible rationales for the resulting versions of the Harm Principle. Again, no plausible version of the principle turns up. I also consider the prospect of including the Harm Principle in a decision-procedure rather than in a criterion of rightness. Finally, in light of my negative appraisal, I briefly discuss why this principle has seemed so appealing to liberals.     

组合原则

组合原则是逻辑语义学的基本原则,表现为函项的思想和句法与语义的对应。就构造逻辑系统而言,组合原则是一种方法论。作为延伸到自然语言形式语义学的产物,组合原则起到一种核心灵魂的作用。组合原则在理论层面和应用领域皆获得一些有价值的结果。自然语言违反组合原则的实例主要表现为歧义现象、语用因素和句法与语义不对应的情况,这正是调整组合原则的适用条件从而促进形式语义学发展的契机。
