父母对幼儿消极情绪的反应方式与幼儿情绪调节能力的关系

以西安市280名幼儿及其家长为被试,采用问卷法考察母亲、父亲对幼儿消极情绪的反应方式对幼儿情绪调节能力的单独效应和联合效应。结果发现：（1）母亲对幼儿消极情绪的支持反应正向预测幼儿的情绪调节能力,非支持反应负向预测幼儿的情绪调节能力;（2）父亲对幼儿消极情绪的支持反应和非支持反应显著预测女孩的情绪不稳;（3）在女孩的情绪调节能力上,母亲和父亲非支持反应的交互作用显著,部分支持了分歧模型。     

Facilitation of return in voluntary orienting to visual attributes1

Abstract: The present study examined the effects of voluntary and automatic orienting after a relatively long interval in an attentional cueing paradigm. Facilitation of return was observed after the voluntary orienting to a designated color (Experiment 1) and motion direction (Experiment 2), whereas inhibition of return was observed after the automatic orienting to an abrupt stimulus onset (Experiment 1). These results suggest that the voluntary orienting to a visual attribute modulates subsequent processes differently from the automatic orienting to an abrupt onset. In the voluntary orienting to visual attributes, it would be advantageous to return attention to the previously attended location, which is a potential source of information.     

智力与信息加工速度研究中的检测时范式

检测时是信息加工速度的重要指标,也是智力与信息加工速度关系的研究领域内一种重要的实验范式。文章在简要介绍反应时范式的基础上,着重介绍了检测时范式的实验任务、基本原理以及检测时与智商之间的关系。同时,通过与反应时范式的比较,讨论了检测时范式在智力与信息加工速度研究中的优点和局限性,以及其在解决相关研究领域问题上的方法学意义。     

传统美德认同和责任情境对大学生责任行为倾向的影响

责任行为是个体在特定责任情境下履行责任和承担后果的行为。本研究采用问卷调查方法着重探讨大学生的传统美德认同和责任情境因素对责任行为倾向的影响。结果表明,传统美德认同,以及责任情境中的责任性质和责任对象都对大学生的责任行为倾向有显著影响,且三者的交互作用显著：（1）传统美德认同高的大学生在履行责任情境中,其责任行为倾向显著强于美德认同低的大学生;（2）履行责任时的责任行为倾向显著强于承担后果时的责任行为倾向,但低美德认同者的两种行为倾向在他人责任情境中无差异;（3）在履行责任情境中,大学生对自我的责任行为倾向显著强于对他人的责任行为倾向;但美德认同低的大学生在承担后果情境中则相反。     

A memory-based model of Hick's law

We propose and evaluate a memory-based model of Hick’s law, the approximately linear increase in choice reaction time with the logarithm of set size (the number of stimulus–response alternatives). According to the model, Hick’s law reflects a combination of associative interference during retrieval from declarative memory and occasional savings for stimulus–response repetitions due to non-retrieval. Fits to existing data sets show that the model accounts for the basic set-size effect, changes in the set-size effect with practice, and stimulus–response-repetition effects that challenge the information-theoretic view of Hick’s law. We derive the model’s prediction of an interaction between set size, stimulus fan (the number of responses associated with a particular stimulus), and stimulus–response transition, which is subsequently tested and confirmed in two experiments. Collectively, the results support the core structure of the model and its explanation of Hick’s law in terms of basic memory effects.     

Contribution of temporal preparation and processing speed to simple reaction time in persons with Alzheimer’s disease and mild cognitive impairment

Temporal preparation was assessed in 15 Alzheimer’s disease (AD) patients, 20 persons with mild cognitive impairment (MCI) and 28 healthy older adults. Participants completed a simple reaction time task in which the preparatory interval duration varied randomly within two blocks (short versus long temporal window). Results indicated that AD and MCI patients had difficulty preparing for the shortest preparatory interval of the short temporal window. AD and MCI patients also had difficulty maintaining an optimal level of preparation up to 5 s within the short temporal window. These results suggest that AD and MCI patients might show difficulty preparing for rapidly occurring events and maintaining preparation over time. This phenomenon should be considered when using reaction time measures with such patients.     

基于认知和情绪反应的工作场所无礼行为发展模型

无礼行为在工作场所中广泛存在, 但由于其强度低、意图模糊等特征, 从而使组织很难有效地甄别、预防或控制它。在总结工作场所无礼行为已有研究成果的基础上, 笔者展开了下列三方面的工作：首先, 厘清无礼行为与其他相关不良行为的概念边界; 其次, 梳理了工作场所无礼行为的相关理论模型的发展进程, 主要介绍情绪认知评价理论模型、情感事件理论模型和无礼行为的情绪反应模型; 最后, 基于目前研究存在的问题和不足, 主张建构一个以认知和情绪反应为中介, 以社会文化、人格和组织因素为调节变量的无礼行为的模型, 并建议未来的研究运用纵向实验设计的方法来确定各变量之间的因果走向, 以求进一步丰富、完善和深化无礼行为的发展机制模型。

启动实验中收集基线反应时的必要性问题

启动实验的有效条件之一是,控制组和实验组的目标词在基线反应时上相同,但在实际操作中,不少研究没有收集基线反应时,只是确保了两组目标词在频率上相同.本研究实验结果显示:对于母语而言,如果词频很高,相同频率的词得到相同反应时的机率很大;相反,机率就比较低;对于外语而言,这种机率相对更低.实验说明,相同词频的词不一定能得到相同的反应时,因此收集基线反应时是启动实验不可或缺的步骤.     

Rapid facial reactions to emotional facial expressions in typically developing children and children with autism spectrum disorder

Typical adults mimic facial expressions within 1000 ms, but adults with autism spectrum disorder (ASD) do not. These rapid facial reactions (RFRs) are associated with the development of social-emotional abilities. Such interpersonal matching may be caused by motor mirroring or emotional responses. Using facial electromyography (EMG), this study evaluated mechanisms underlying RFRs during childhood and examined possible impairment in children with ASD. Experiment 1 found RFRs to happy and angry faces (not fear faces) in 15 typically developing children from 7 to 12 years of age. RFRs of fear (not anger) in response to angry faces indicated an emotional mechanism. In 11 children (8-13 years of age) with ASD, Experiment 2 found undifferentiated RFRs to fear expressions and no consistent RFRs to happy or angry faces. However, as children with ASD aged, matching RFRs to happy faces increased significantly, suggesting the development of processes underlying matching RFRs during this period in ASD.
