虚拟团队学习效能研究:社会认知因素的影响

本研究采用现场研究的方法,对21个虚拟团队学习的效能进行了实证研究。研究对社会认知因素中的效能感和目标取向对虚拟团队学习效能(技能改变、工作任务和团队健康水平)的影响进行了研究,并探讨了对虚拟团队的态度在中间所起的作用。研究发现,虚拟团队效能感和学习取向对虚拟团队的学习效能产生作用,而对虚拟团队学习的态度、团队信任对虚拟团队学习的效能起着中介或直接的作用。     

汉字错误记忆的形、音编码差异研究

采取DRM范式,要求被试判断词表项目的字形结构或音调,从而间接学习词表,考察了关联性、不同编码方式和测验情境（测验次数、测验词颜色两个变量）对真实和错误记忆的影响。实验发现：（1）随着关联性的增加,未学词的错误再认率也增加,说明关联性是引发错误记忆的必要条件;（2）字形判断比字音判断下的错误再认率要高,说明汉字中形—义联结可能比音—义联结更加紧密;（3）测验情境对真实和错误记忆影响并不相同,表明两者虽然同源,但具有完全不同的机制。

Frames of reference in mobile augmented reality displays

In 3 experiments, the authors investigated spatial updating in augmented reality environments. Participants learned locations of virtual objects on the physical floor. They were turned to appropriate facing directions while blindfolded before making pointing judgments (e.g., "Imagine you are facing X. Point to Y"). Experiments manipulated the angular difference between the learning heading and the imagined heading and between the actual heading and the imagined heading. The effect of actual-imagined on pointing latency was observed for naive users but not for users with brief training or instructions concerning the fact that objects can move with body movements. The results indicated that naive users used an environment-stabilized reference frame to access information arrays, but with experience and instruction the nature of the representation changed from an environment stabilized to a body stabilized reference frame.     

初中生亲子冲突、朋友冲突对孤独感的影响及其性别差异：一项交叉滞后研究

对1330名初中生进行间隔一年的追踪测试,通过交叉滞后的方法探讨亲子冲突、朋友冲突和孤独感之间的相互作用。结果发现,对男生而言,先前亲子冲突对随后朋友冲突和孤独感预测作用不显著,而朋友冲突与孤独感为相互预测关系,亲子冲突和朋友冲突不存在显著预测关系;对女生而言,先前亲子冲突可以显著正向预测随后孤独感,而朋友冲突则不能,亲子冲突与朋友冲突为相互预测关系。结论：朋友冲突对男生的孤独感影响更大,亲子冲突对女生的孤独感影响更大。     

Study of γ/γ′ interfacial width in a nickel-based superalloy by scanning transmission electron microscopy

The γ/γ′ interfaces are thought to play an important role in determining the mechanical properties in single-crystal nickel-based superalloys. In this article, interfacial width in DD6, one second-generation single-crystal superalloy containing 2 wt% Re, has been studied by means of scanning transmission electron microscopy. From an atomic resolution high angle annular dark field image, both compositional interfaces and order–disorder interfaces are studied, and it is first found that the interfacial width of chemical composition is same with that between the ordered and disordered phases.     

Unconsciously learning task-irrelevant perceptual sequences

We demonstrated unconscious learning of task-irrelevant perceptual regularities in a Serial Reaction Time (SRT) task in both visual and auditory domains. Participants were required to respond to different letters (‘F’ or ‘J’, experiment 1) or syllables (‘can’ or ‘you’, experiment 2) which occurred in random order. Unbeknownst to participants, the color (red, green, blue or yellow) of the two letters or the tone (1–4) of the syllables varied according to certain rules. Reaction times indicated that people indeed learnt both the color and tonal regularities indicating that task-irrelevant sequence structure can be learned perceptually. In a subsequent prediction test of knowledge of the color or tonal cues using subjective measures, we showed that people could acquire task irrelevant knowledge unconsciously.     

Web2.0环境中顾客参与的实现型快乐感形成机制

随着以用户间交互为特征的Web 2.0理念的深入发展,顾客期望借助互联网参与到价值的生产与创造过程中,以期通过自我潜能发挥和自我价值展示寻求获得一种有别于享乐型快乐感的实现型快乐感.以往顾客参与研究大多关注其经济利益、如何管理、影响因素、获得的实际利益,而对于顾客参与过程中的心理机制和参与后的心理收获研究不多.本研究以互联网为背景,从顾客视角出发,科学采用实验、实证等多种方法,并尝试采用生理仪器(如多导仪、脑电核磁共振仪等)采集顾客行为和生理的客观数据,利用自我决定理论对顾客参与过程的心理反应和参与后的心理收获进行系统探讨,构建顾客参与过程的心理动态模型.     

The Effects of Self-Esteem,Task Label,and Performance Feedback on Goal Setting,Certainty, and Attribution

An identical task was labeled as either difficult or easy. Bogus performance feedback was given to each subject at random after the first work period. Subjects were divided into high or low self-esteem groups based on a median split in their scores on the self-esteem measure. The results showed that subjects set lower goals in the difficult condition than they did in the easy condition in the first period; however, no difference was found in the second period. Subjects with high self-esteem had higher certainty than those with low self-esteem in the second period. Subjects in the positive feedback group made higher ability and effort attributions than those in the negative feedback group.     

书法练习对儿童情绪及其调节策略发展的促进作用

本研究采用纵向设计,对170名儿童（实验组：101人;对照组：69人）进行为期两学年的追踪,旨在探讨书法练习对儿童情绪状态及认知性情绪调节策略发展的影响。研究发现,1）以前测成绩为协变量,后测时实验组的积极情绪显著高于对照组;2）实验组在“积极重新关注”、“计划”两维度上的情绪调节策略得分增量（后测-前测）显著高于对照组。结果表明,书法练习对儿童情绪及其调节策略发展具有促进作用。
