Experimental analysis of preschool playmate preferences as a function of smiles and sex

Differential emotions theory (DET) (The face of emotion. Appleton‐Century‐Crofts: East Norwalk, CT, 1971) posits that the smile functions in part to communicate and/or reflect social affiliation and plays an important role in children's social development. While children's positive emotion expressions have received attention from peer relations researchers in observational studies and within correlational designs, there is almost no experimental evidence for the impact of the smile. Building on existing studies, the present study examined DET predictions within an experimental design. More specifically, we examined the impact smiles have on lower‐income preschool children's nominations for preferred playmates. Both boys and girls tended to nominate unfamiliar playmates who smiled. Additionally, some evidence suggested that preference for smiling playmates seemed more critical to girls' than boys' social functioning. Unlike among boys, teachers rated girls who exhibited a greater preference for smiling playmates as higher in social competence. Copyright © 2008 John Wiley & Sons, Ltd.     

Associations between mothers' sensitivity to their infants' internal states and children's later understanding of mind and emotion

This study investigated associations between mother–infant interactions and children's subsequent understanding of mind and emotion. Mothers' tendency to comment on their infants' internal world and their general sensitivity to their infants' internal states were measured through coded play interactions at 10 months. The latter measurement included ratings on four aspects of maternal behaviour: mindful facilitation, joint attention commenting, pacing, and affect catching. In contrast to mothers' internal state language, these behaviours did not tap mothers' explicit linguistic representation of their infants' mental states. At 54 months, children's understanding of mind and emotion was measured through a range of false‐belief tasks and an emotion‐understanding task. Multivariate analysis revealed direct positive links between mothers' sensitivity to their infants' internal states and children's later understanding of mind.

类比数量表征的线索:离散量还是连续量

运用Stroop研究范式,对30名成人被试的类比数量表征线索进行了研究。结果发现:在类比数量的小数和大数段上,不存在表征线索的分化;在个数任务中不出现Stroop效应,但被试在强不一致条件下的错误率显著高于强一致条件下的错误率;在累积面积任务中出现Stroop效应,且在弱不一致、强不一致条件下的反应时、错误率都显著高于强一致、弱一致条件下的反应时、错误率。以上结果表明被试在进行类比数量表征时,可以同时提取离散量线索和连续量线索,但是对离散量线索的抑制要难于对连续量线索的抑制。     

婴儿气质的实验室观察与母亲报告的一致性及其影响因素研究

本研究采用呈现三种性质物品的实验室观察法与母亲报告法,考察203名6个月婴儿在积极情绪和消极情绪的一致性。结果表明:(1)在正性情境下,实验室观察的积极、消极情绪与母亲报告的消极情绪显著相关;(2)母亲的抑郁倾向与两种气质测查方法测查的婴儿消极情绪的一致性正相关显著;婴儿性别在一定程度上调节着母亲养育压力与两种方法测查婴儿积极情绪的一致性。     

项目反应理论新进展：基于3PLM和GRM的混合模型

IRT中的计量模型较多,不同计量模型适合不同特点的数据资料,实际工作者应根据实际情况选择适当的IRT模型来分析数据。我国是个考试、测评大国,测评的题型丰富多样,在实际应用IRT时,一个模型往往很难反应所有数据资料本身的特点,这时可考虑应用多个IRT模型（即“混合模型”）来分析,以达到对数据的最佳拟合。本文对混合模型的思想方法及原理、参数估计的实现、以及模型性能进行了研究,发现：（1）本文自主开发的混合模型参数估计程序Mix_Tu具有较高的返真性,且与国际知名测量软件Parscale相当。（2）在“项目异常”情况下,Mix_Tu程序对参数b和c的估计受数据异常程度的影响要大于Parscale程序,而对参数a的估计受数据异常程度的影响要小于Parscale程序,而在参数theta上两个程序相当。（3）在“被试异常”情况下,Mix_Tu程序对所有参数的估计受数据异常程度的影响均要小于Parscale程序,Mix_Tu程序表现的更为稳健。     

教育水平在认知老化中的作用

为考察教育水平在认知老化中的作用,分别使用横断数据和干预数据分析教育水平对认知老化的影响模式。对51名58～83岁的城市社区老年人实施加工速度测验和基本心理能力测验。随机选取25名被试作为干预组接受加工速度训练。被试在前测后第8周接受与前测内容相同的后测。横断分析的结果显示,在特定的认知测验中,教育水平对认知能力的年龄差异有调节作用。干预数据的分析结果显示,加工速度干预效果显著,且对词汇流畅性有迁移作用。但相关分析和回归分析的结果则表明,教育水平在促进老年人干预收益和迁移方面的作用不显著。在获取和应用新知识方面,教育水平的作用并不显著,其在认知老化中的作用可能更多地表现为对固有认知功能的保护。     

对称场景中朝向一致性对内在参照系的影响

采用部分场景再认范式研究了对称场景中物体朝向的一致性对内在参照系建立的影响。被试在实验1中沿对称轴方向学习无朝向物体组成的场景; 实验2中沿对称轴方向学习有朝向物体组成的场景; 实验3中沿对称轴与物体朝向方向学习与实验2相同的场景。结果表明：(1)物体朝向一致性影响了对称场景中内在参照方向的选择; (2)无论是否存在观察视点的干扰, 观察者选择对称轴和物体的一致朝向作为内在参照方向的可能性没有显著差异。     

幻忆现象研究现状述评

幻忆(Déjà vu)是指任何对目前体验的一种不适宜的熟悉感, 并伴随着对过去体验的不确定感。年龄、梦、教育水平、旅行经历、生理状况和药物都会对幻忆产生造成影响。研究发现, 内侧颞叶和嗅内皮质与幻忆有着紧密的联系。目前主要通过知觉分离范式、情景再现范式、单成分元素交互作用范式、无辨别再认范式和催眠范式来研究幻忆现象。幻忆的研究仍然存在着若干问题, 这些问题需要进一步探讨。     

什么决定着用户对产品的完整体验?

用户体验是以用户与产品的交互为基础而形成的用户对产品的完整感受。研究其决定因素可以有针对性地提高用户体验。早期研究表明, 可用性、美感和情感都有重要影响但皆不是唯一的决定因素, 近年来的研究重点关注于多因素整合理论及其模型的建立。在总结实效/享乐结构理论、用户-企业-产品双层结构理论和四种过程模型以提取用户体验影响因素的基础上, 提出目前研究的突破点可在三方面, 一是深入探讨各因素的作用, 二是揭示社会型产品用户体验的形成规律, 三是揭示用户体验随时间变化的规律。     

The dominance of fear over hope in the life of individuals and collectives

We address the question why fear dominates hope in the life of individuals and collectives on the basis of the accumulated knowledge in the psychology, neurology and sociology of emotions. This knowledge suggests that fear, as primary emotion, is grounded in the experienced present and based on the memorized past, processed both consciously and unconsciously, causes freezing and conservatism, and sometimes leads to pre‐emptive aggression. Hope, in contrast, as a secondary emotion, involves cognitive activity, which requires anticipation and the search for new ideas and thus is based on complex processes of creativity and flexibility. Therefore, hope is often preceded and inhibited by spontaneous, automatically activated and faster fear. Fear and hope can each become a collective emotional orientation, and as such organize society's views and direct its actions. Societies involved in intractable conflict are dominated by a collective fear orientation. This orientation is functional for society's coping with the stressful and demanding situation—but it may serve as a psychological obstacle to any peace process, once it starts. The case of the collective fear orientation in the Jewish Israeli society is presented as an example. The article ends with a presentation of a particular approach, suggesting that individuals and collectives can overcome their fear with much determination, and establish an orientation of hope which allows change in situations dominated by fear.
