儿童依“相似性”分类能力的发展及影响分类结果因素的实验研究

以4-9岁儿童为被试,用6张主要是相同事物的多少有差异的刺激图片为实验材料,采用全部呈现刺激图片和逐——呈现刺激图片,并且利用有无目标图的方法,来探讨儿童依“相似性”分类能力的发展及影响分类结果的因素。结果表明:(1)随着年龄的增长,儿童依“相似性”分类的能力在提高。(2)按目标图分类方式的分类结果显著好于自由分类方式的分类结果。(3)逐一呈现刺激方式的分类成绩显著好于全部呈现刺激方式的分类成绩。     

Acalculia and Dyscalculia

Even though it is generally recognized that calculation ability represents a most important type of cognition, there is a significant paucity in the study of acalculia. In this paper the historical evolution of calculation abilities in humankind and the appearance of numerical concepts in child development are reviewed. Developmental calculation disturbances (developmental dyscalculia) are analyzed. It is proposed that calculation ability represents a multifactor skill, including verbal, spatial, memory, body knowledge, and executive function abilities. A general distinction between primary and secondary acalculias is presented, and different types of acquired calculation disturbances are analyzed. The association between acalculia and aphasia, apraxia and dementia is further considered, and special mention to the so-called Gerstmann syndrome is made. A model for the neuropsychological assessment of numerical abilities is proposed, and some general guidelines for the rehabilitation of calculation disturbances are presented.     

人本主义健康人格和儒家理想人格的比较研究

人格心理学的研究不仅应注重对心理现象的理解,更应该致力于人类心理问题的解决和人类心理生活质量的提高。对健康人格(或理想人格)的追求,是东西方思想家为之不懈的努力。人本主义健康人格和儒家理想人格是东西方两种理想的人格模式,虽然东西方文化传统所赋予的内容不同,但都是一种人生发展的目标。本文对两者进行了比较研究,认为两者既有差异之处,又有相似之处,同时两者对塑造现代人格有很大启示。     

6—12岁儿童脑波超慢涨落功率与计算速度的关系

对176名6-12岁认知功能正常小学生进行脑波超慢涨落平均功率分布与计算速度关系的研究。结果表明：(1)计算速度快组和计算速度慢组中各年龄组的脑区平均功率符合额低枕高的前后梯度。计算速度慢组的逆转百分率高于计算速度快组。(2)在各年龄组中,计算速度快组和慢组功率前后逆转百分率的差异主要反映在右脑,右脑功率前后梯度逆转在不同计算组之间差异较大。(3)在计算速度快组和慢组中,左脑平均功率都小于右脑平均功率。计算速度快组和慢组脑波功率左右逆转百分率的差异主要反映在后脑,后脑功率左右逆转在逆转总数上计算速度快组多于计算速度慢组。     

When Likeness Goes with Liking: The Case of Political Preference

Three studies show that people tend to vote for politicians (i.e., either Romano Prodi or Silvio Berlusconi in Italy or George W. Bush or John Kerry in the United States) whose traits they rate as being most similar to their own. People perceived higher similarity between themselves and political figures with respect to traits that were most distinctive of each platform and their respective leaders. These findings, while corroborating the similarity-attraction relationship, further attest to the role that personal characteristics of both voters and candidates play in orienting political preference.     

Social closeness of MZ and DZ twin parents towards nieces and nephews

Twins' marriages to non‐twins yield genetically and socially informative kinships. Monozygotic (MZ) twins' genetic identity makes them ‘genetic parents’ of their nieces/nephews, and their nieces/nephews their ‘genetic children’. The present study is the first to apply twin‐family models to study social relatedness. Analyses of twin families (MZ: N = 248; DZ: N = 75) tested evolutionary‐based concepts concerning social closeness, perceived similarity and caretaking. Hypotheses based on Hamilton's inclusive fitness theory were supported: MZ twin aunts/uncles expressed greater social closeness towards their nieces/nephews than DZ twin aunts/uncles; and female twins from same‐sex pairs expressed greater closeness towards their nieces/nephews than male twins from same‐sex pairs. This study underlines benefits of associations between behavioural‐genetic and evolutionary psychological theories, methods and interpretations. Copyright © 2007 John Wiley & Sons, Ltd.     

物体颜色与质地相似度对幼儿归纳推理的影响

设计了3个实验任务,探讨物体颜色相似度与质地相似度对140名4~6岁幼儿和40名成年人的归纳推理的影响。结果发现,在任务1中,当靶物体质地保持不变时,幼儿和成年人在归纳推理中倾向于选择与靶物体在颜色上更相似的物体;在任务2中,当靶物体颜色不变时,幼儿和成年人倾向于选择与靶物体在质地上更相似的物体;在任务3中,当测试物体在颜色相似度和质地相似度上发生相反变化时,4岁幼儿显著地依赖于质地相似度进行归纳,颜色相似度在5~6岁时的重要性明显提高,但仍略低于质地相似性,差异不显著,这表明颜色相似度和质地相似度在幼儿的归纳推理中具有不同程度的重要性。对成年人而言,颜色相似度虽然看起来比质地相似度相对更重要性,但差异不显著。     

Cogex: A semantically and contextually enriched logic prover for question answering

This paper presents the architecture and functionality of a logic prover designed for question answering. The approach transforms questions and answer passages into logic representations based on syntactic, semantic and contextual information. World knowledge supplements the linguistic, ontological, and temporal axioms supplied to the prover which renders a deep understanding of the relationship between the question and answer text. The trace of the proofs provides a basis for generating human comprehensible answer justifications. The results show that the prover boosts the performance of the Question Answering system on TREC 2004 questions by 12%.     

工作记忆在数学运算过程中的作用

Baddeley和Hitch(1974)提出的工作记忆模型被广泛地应用数学运算领域,但是已有研究还缺乏系统性。首先,当前的研究主要集中在加法和乘法两种运算上,较少涉及减法、除法和更为抽象的代数运算;第二,研究者对语音环路和中央执行系统的作用进行了较深入的研究,但常常忽略视空间模板的作用;第三,工作记忆在数学运算过程中的作用具有动态性,它受到一些外部因素、数学任务内在因素和个体认知因素（如认知策略）的影响;第四,几乎有关研究都肯定中央执行系统在数学运算过程中的重要作用,然而负荷于中央执行系统的次级任务所含成分或功能的复杂性,导致我们很难确定中央执行系统如何作用于数学运算。对这些问题的研究将是未来可能的研究方向     

A New Analysis of Quasianalysis

We investigate the conditions under which quasianalysis, i.e., Carnap's method of abstraction in his Aufbau, yields adequate results. In particular, we state both necessary and sufficient conditions for the so-called faithfulness and fullness of quasianalysis, and analyze adequacy as the conjunction of faithfulness and fullness. It is shown that there is no method of (re-)constructing properties from similarity that delivers adequate results in all possible cases, if the same set of individuals is presupposed for properties and for similarity, and if similarity is a relation of finite arity. The theory is applied to various examples, including Russell's construction of temporal instants and Carnap's constitution of the phenomenal counterparts to quality spheres. Our results explain why the former is adequate while the latter is bound to fail.
