选择、自我表达与选择扩散效应

自我表达会影响西方人的态度, 产生选择扩散效应。国外相关的跨文化研究发现东方人不存在该效应。通过4个实验研究中国文化下自我表达对选择态度的影响, 发现选择方式(主动、被动)和自我表达形式(直接、间接)对选择态度产生影响。无论是自己的主动选择还是强加的被动选择, 直接的自我表达会增加对所获对象的喜爱程度, 表现为对获得性的肯定。研究者认为, 两种选择方式下不同的心理加工过程导致了这种获得性：直接表达使个人态度暴露在外, 进行主动选择时要对他人的给予做出肯定回应; 而进行被动选择时, 人们要减缓因利益受损可能导致的失调, 同时中国文化下的面子策略也使人们增加对所获对象的喜爱程度。不过, 间接的自我表达对选择态度的影响不明显。研究者认为, 多个影响因素的相互消长使选择态度得以维持。     

论人格特质“大七”因素模型

概要介绍和评价了人格特质“大七”因素模型。该模型继承了传统特质分类研究中的“词汇假设”思想和因素分析方法．并在选词标准及方法的客观性上有所改进和提高．在“大五”基础上增加了两个评价维度。文章指出“大七”存在一些问题。     

跟踪操作业绩与人格特征的关系

本研究发现,跟踪作业的业绩与允许误差值之间有某种规律性的关系。因此,跟踪任务的操纵器设计应考虑最佳宽容度。本文还探讨了不同人格维度与跟踪作业业绩之间的关系。就单个人格维度而言,内倾者的跟踪作业业绩优于外倾者;较高精神质者优于较低精神质者。在神经质维度上表现出高神经质者作业业绩好于低神经质者的倾向。     

The Logic and Meaning of Plurals. Part II

In this sequel to “The logic and meaning of plurals. Part I”, I continue to present an account of logic and language that acknowledges limitations of singular constructions of natural languages and recognizes plural constructions as their peers. To this end, I present a non-reductive account of plural constructions that results from the conception of plurals as devices for talking about the many. In this paper, I give an informal semantics of plurals, formulate a formal characterization of truth for the regimented languages that results from augmenting elementary languages with refinements of basic plural constructions of natural languages, and account for the logic of plural constructions by characterizing the logic of those regimented languages.

Emergent, untrained stimulus relations in many-to-one matching-to-sample discriminations in rats

The present experiment investigated whether rats formed emergent, untrained stimulus relations in many-to-one matching-to-sample discriminations. In Phase 1, rats were trained to match two samples (triangle and horizontal stripes) to a common comparison (horizontal stripes) and two additional samples (circle or vertical stripes) to another comparison (vertical stripes). Then, in Phase 2, the rats were trained to match the one sample (triangle) to a new comparison (black) and the other sample (circle) to another comparison (white). In the Phase 3 test, half the rats (consistent group) were given two new tasks in which the sample-correct comparison relation was consistent with any emergent stimulus relations that previously may have been learned. The remaining 6 rats (inconsistent group) were given two new tasks in which the sample-correct comparison relation was not consistent with any previously learned emergent stimulus relations. Rats in the consistent group showed more accurate performance at the start of Phase 3, and faster learning to criterion in this phase, as compared with rats in the inconsistent group. This finding suggests that rats may form emergent, untrained stimulus relations between the discriminative stimuli in many-to-one matching-to-sample discriminations.     

《易纬·稽览图》"一爻直一日"卦气术考

<易纬·稽览图>卷下载有一种"一爻直一日"的卦气占术,还少见学者讨论.本文对这一占术作了梳理,并对其特点、流传作了初步考察.与<稽览图>卷下"六日七分"卦气术不同,<稽览图>"一爻直一日"的卦气术,与焦赣"焦林直日"卦气说有密切的关系,二者可能同属于<连山><归藏>系统.此术至唐一直在流传.     

On the inseparability of reasoning and virtue: Madame de Maintenon's Maison royale de Saint-Louis

This paper engages with the curriculum at Madame de Maintenon's school for girls at Saint-Cyr to raise and address a set of questions: What is it to teach someone to reason? The curricular materials of Saint-Cyr suggest that learning to reason is a matter of practice. How is one to distinguish autonomous reason giving from habituation or automatic trained responses? How can practices in reason giving informed by social mores have objective validity? Moreover, if we think of the role of a philosopher as the cultivation of rational faculties and recognize that how this role is played is bound up with social norms, by what standards ought we to evaluate whether a philosophical educator is good or bad? Intertwined with the discussion is also a question about the limits of philosophy for the question.     

雏鸡左眼视剥夺不同时程后记忆形成过程与脑内Jun样蛋白表达差异的研究

本实验采用一次性味觉厌恶回避学习,研究２日龄雏鸡左眼视剥夺２４小时后的记忆形成过程,并与左眼视剥夺２小时后的记忆形成过程进行比较,同时利用免疫组化技术,观察并比较单眼视剥夺不同时程及单眼学习后Ｊｕｎ样蛋白在雏鸡脑内不同区域（ＨＶ和ＬＰＯ）的表达。结果表明：１．视剥夺左眼２４小时后对雏鸡的短时记忆、中时记忆和长时记忆均无明显影响,但中时记忆保持水平略低于双眼学习条件下的中时记忆保持水平。这与视剥夺２     

类别成员跨维度特征关系对类别学习的影响

探讨类别成员具有多维度相同特征与多维度匹配特征条件下对人们类别学习的影响。被试来自华南师范大学一年级本科生,要求他们学习不同特征结构的类别材料,然后进行测试,以学习阶段的单元数与错误率、测试阶段的反应时与错误率为指标。共包括3个实验,实验1探讨了类别成员具有双维度相同特征、双维度匹配特征与非匹配特征条件下进行类别学习的成绩。实验2探讨类别成员在空间位置分离的两个维度上具有相同特征对类别学习的影响。实验3进一步探讨类别间成员具有双维度相同特征对类别学习的影响。结果表明：（1）类别成员具有双维度相同特征时,人们在归类学习中会将这两个维度看成是一个维度,从而促进类别学习;（2）类别成员具有双维度匹配特征,或者在两个不相邻维度具有相同特征时,对于类别学习没有起到这种特定的促进作用;（3）如果类别间成员具有双维度相同特征,则对类别学习产生消极影响。研究结果表明,在类别学习过程中,特征相似性状况对维度的确立也会产生影响。     

基本情绪的神经基础：来自fMRI与机器视觉技术研究的证据

基本情绪理论(basic emotion theory)是情绪科学领域最具代表性的理论, 该理论认为人类情绪是由有限的几种基本情绪组成的, 如恐惧、愤怒、喜悦、悲伤等。基本情绪是为了完成基本生命任务(fundamental life task)进化而来的, 每一种基本情绪都有独特的神经结构和生理基础。尽管基本情绪理论被广泛接受, 但是对于基本情绪的种类却莫衷一是。近几十年来, 许多fMRI研究试图确定各种基本情绪的独特神经结构基础, 而且取得了许多重要发现, 比如厌恶和脑岛有关, 悲伤和前扣带回有关, 杏仁核是与恐惧有关的重要边缘结构等。但是, 最近有人进行了元分析研究, 发现许多基本情绪存在混淆的大脑区域, 因此对基本情绪的特定脑区理论提出质疑, 甚至否定基本情绪理论。通过对基本情绪及其神经基础的探讨, 以及对基本情绪理论的最新功能性磁共振成像研究进行梳理分析, 提出有关基本情绪理论的争论来源于基本情绪种类的确定, 因为许多所谓的不同基本情绪实际上是同一种基本情绪, 提出人类可能只有3种基本情绪。未来研究可以利用机器视觉技术进一步推动基本情绪脑影像研究。
