核心知识系统及其对相关研究的启示

核心知识系统出现于人类个体发展和种系发展的早期,在人类复杂认知能力的发生发展中起着建构模块的作用。该文以表征物体和数量关系的两类核心知识系统的性质及二者在儿童的“数”概念形成和成人的数学思维中所起的作用为例,综述了以灵长类动物、婴儿、儿童和成人为被试的研究证据,并进而提出了核心知识系统给相关研究带来的若干启示。     

尼古丁依赖对男性吸烟者感知戒烟行为控制的预测：社会支持与抱怨批评的作用

考察尼古丁依赖对男性吸烟者感知戒烟行为控制的预测及他人戒烟社会支持和抱怨批评的调节作用。对326名男性吸烟者进行问卷调查,结果显示：（1）尼古丁依赖显著负向预测感知行为控制;（2）社会支持和抱怨批评共同调节两者关系;在高社会支持且低抱怨批评、高抱怨批评且低社会支持的条件下,尼古丁依赖的预测作用不显著。结果说明,高社会支持在尼古丁依赖削弱感知行为控制过程中起缓冲作用,而高抱怨批评削弱社会支持的缓冲作用。     

样例数量对内隐序列学习的影响

本研究采用序列学习范式,探讨了样例数量对内隐序列学习的影响,以揭示意识在学习中的作用以及内隐学习获得的知识表征。研究发现,在内隐序列学习中：（1）被试既可以记忆具体的样例知识也可以抽取抽象的规则知识;（2）样例数量影响被试对样例和规则知识的获得,在样例较少时被试可以获得更多的样例和规则知识;（3）样例数量影响被试对意识知识的获得,在本研究中仅当样例数为4时被试获得了有关样例和规则的意识知识。     

Effects of Media and Collaborative Distributed Information on Concept-Learning

1IntroductionSuchman,an anthropologist,argued that actionswere always situated in particular social and physi-cal circumstances[1].In this view actions emergefrom moment-by-moment interactions between ac-tors,and between actors and their environments.The social and environmental aspects of cognitionhave been stressed in Hutchins′work[2].He hadstudied relatively structured decision environments,for example ship navigation and aeroplane piloting.His conclusions are that cognition in such situa…     

Controlling item exposure and test overlap on the fly in computerized adaptive testing

This paper proposes an on‐line version of the Sympson and Hetter procedure with test overlap control (SHT) that can provide item exposure control at both the item and test levels on the fly without iterative simulations. The on‐line procedure is similar to the SHT procedure in that exposure parameters are used for simultaneous control of item exposure rates and test overlap rate. The exposure parameters for the on‐line procedure, however, are updated sequentially on the fly, rather than through iterative simulations conducted prior to operational computerized adaptive tests (CATs). Unlike the SHT procedure, the on‐line version can control item exposure rate and test overlap rate without time‐consuming iterative simulations even when item pools or examinee populations have been changed. Moreover, the on‐line procedure was found to perform better than the SHT procedure in controlling item exposure and test overlap for examinees who take tests earlier. Compared with two other on‐line alternatives, this proposed on‐line method provided the best all‐around test security control. Thus, it would be an efficient procedure for controlling item exposure and test overlap in CATs.     

Perceived deep-level dissimilarity: Personality antecedents and impact on overall job attitude, helping, work withdrawal, and turnover

The current research extends three research areas in relational demography: considering deep-level dissimilarity in theory building, assessing dissimilarity perceptions directly in theory testing, and examining the antecedents of dissimilarity perceptions. The results, based on two field studies using diverse samples, demonstrate the effects of enduring personality traits of Extraversion and Agreeableness on an individual’s perceived deep-level dissimilarity to coworkers in the workgroup, and the effects of perceived deep-level dissimilarity beyond the effects of actual dissimilarity and perceived surface-level dissimilarity on critical work outcomes, including the individual’s overall job attitude, and behaviors of helping, work withdrawal, and actual voluntary turnover.     

Intentional control based on familiarity in artificial grammar learning

It is commonly held that implicit learning is based largely on familiarity. It is also commonly held that familiarity is not affected by intentions. It follows that people should not be able to use familiarity to distinguish strings from two different implicitly learned grammars. In two experiments, subjects were trained on two grammars and then asked to endorse strings from only one of the grammars. Subjects also rated how familiar each string felt and reported whether or not they used familiarity to make their grammaticality judgment. We found subjects could endorse the strings of just one grammar and ignore the strings from the other. Importantly, when subjects said they were using familiarity, the rated familiarity for test strings consistent with their chosen grammar was greater than that for strings from the other grammar. Familiarity, subjectively defined, is sensitive to intentions and can play a key role in strategic control.     

视觉标记：一种优先选择机制

视觉标记是与任务目标相关的自上而下的优先选择解释机制。视觉标记理论对preview效益——对后出现项目的视觉优先选择现象——提供了合理的解释：对先出现的项目自上而下的抑制提高了对后出现项目的优先选择等级。首先介绍视觉标记经典实验范式和preview效益,然后阐述研究者对视觉标记抑制机制的两种主要观点,进而介绍其他优先选择理论对preview效益的解释及其局限性,最后指出视觉标记研究中亟待解决的问题     

论人力资本、社会资本和道德资本

人力资本、社会资本、道德资本是当前国际范围内的学术热点问题.但是三者之间并不是各不相干的,而是有着深刻的内在关联.它们的关系主要表现在:人力资本包含了社会资本和道德资本,或者反过来说,没有社会资本和道德资本的人力资本是不完全和不完善的;社会资本从社会角度丰富和深化了人力资本的内涵,而道德资本则从个体角度丰富和深化了人力资本的内涵;人力资本主要适用于经济和管理领域,而社会资本和道德资本不仅适用于经济和管理领域,而且也适用于广泛的社会领域和个人生活领域.     

区分度在面部表情与面孔身份识别交互中的作用

已有研究表明,身份对面部表情识别的影响较常见,但表情对面孔身份识别的影响却很罕见。只有个别研究发现了表情对熟悉面孔身份识别的影响。最近有研究使用非常相似的模特面孔图片为实验材料,也发现了表情对身份识别的影响,并提出在以往研究中表情不影响身份识别是因为身份的区分度高于表情的区分度。本研究置疑表情区分度低于身份区分度的必然性,认为过去的研究使用静态表情图片,使得表情自然具有的强度变化线索缺失,才导致表情的区分度相对较低。本研究假设,当表情的强度变化线索得以体现时,表情的区分度就会提高,此时表情识别可能就不会受身份的影响。实验结果支持该假设,证明表情与身份的区分度水平是决定二者识别交互模式的重要因素。表情身份识别之间的相互影响并不能完全证明这两者之间的独立加工关系。此外,研究结果也提示在一定条件下可以部分分离表情与身份信息
