快慢读者利用语境信息的差异：加工深度的作用

通过主题扫描和阅读理解两种加工深度不同的任务,考察快慢读者预测性效应差异的来源及加工深度在其中发挥的作用。被试在两种任务情境下阅读分别包含高低预测性目标词的96个句子框架,记录其眼动轨迹。结果显示：预测性效应仅在阅读理解任务中出现,快速读者在早期眼动指标上就表现出了预测性效应,慢速读者在晚期眼动指标上才表现出预测性效应。结果表明：加工深度调节快慢读者预测性效应的大小;在自然阅读情境下快慢读者的预测性效应表现符合预测编码框架假设。     

心理病理学视野中的完美主义自我展示

完美主义自我展示是完美主义者在人际过程中为向他人展示自己非现实的、固定化的完美形象而进行的印象整饰过程。本文在简要阐述完美主义特征与澄清完美主义自我展示概念基础上,重点梳理和剖析了完美主义自我展示对抑郁、焦虑、社交恐惧、饮食障碍及人格障碍等常见心理病理现象的影响,并分析了其影响机制,最后,就深化该领域的研究提出了总结和展望。     

Pinning of grain boundary migration by a coherent particle

We studied single-particle pinning of grain boundary (GB) migration during grain growth. A phase-field model was formulated to simulate the pinning by a coherent particle and validated quantitatively by comparison with analytical prediction. A study of GB migration velocity using this model revealed that second-phase coherent particles have a previously unknown restraining effect over the whole of the GB-particle interaction range, which is qualitatively different from the interaction between GB and incoherent particles.     

Microwave-dielectric and magnetic properties of Ta-doped BiFeO3 nanopowders

BiFe_{1? x} Ta _x O₃ (x = 0, 0.05, 0.1) nanopowders have been fabricated by a simple sol–gel method. Dielectric measurements at microwave frequencies (2–18 GHz) were made using a vector network analyser. Without tantalum, the BiFeO₃ nanopowder presents a relaxation-like response with a characteristic frequency of 15 GHz, which can be associated with an overdamped process. The Ta-doped nanopowders, however, show resonant behaviour with resonant frequencies of 12.5 and 14.6 GHz. The intensity of the resonant peak near 14.6 GHz decreases with increasing Ta addition. This behaviour is associated with a damped resonance process. Room-temperature magnetic measurements indicate that the addition of Ta influences the magnetic properties of the BiFeO₃ nanopowders, with BiFe_0.95Ta_0.05O₃ having the strongest ferromagnetism with a saturation magnetisation M _s of about 0.05 µ_B/Fe. The origin of the enhanced ferromagnetism is possibly associated with the distortion of the oxygen octahedral by the Ta substitution or/and the statistical distribution of Fe³⁺ and Fe²⁺.     

Psychological contracts and innovative behavior: a moderated path analysis of work engagement and job resources

This study explored the relationships between psychological contract types and innovative behavior. We focused on the mediating effect of work engagement and the moderating effect of job resources (organizational and social resources). Participants were 267 dyads of research and development engineers and their supervisors from 30 high‐tech companies. Moderated path analysis was used to test the hypotheses. Findings showed that: (a) work engagement fully mediated the negative relationship between transactional contracts and innovative behavior; in addition, it also fully mediated the positive relationship between relational contracts and innovative behavior; and (b) job resources attenuated the former and strengthened the latter mediating effects. These findings contribute to understanding how, why, and when psychological contract types lead to innovative behavior via work engagement.     

决策中的过程追踪技术:介绍与展望

在过去50年的决策研究中,随着对核心问题的深入探索和信息技术的发展,决策过程信息得到了越来越多的重视.过程研究技术主要包括鼠标实验室技术、眼动技术及新提出的决策移窗技术.鼠标实验室技术和眼动技术已被用于解决多种决策问题.决策移窗技术结合了前两种技术的优势,其适用范围需在日后研究中进行更多探索.在未来的研究中,多种技术的结合使用将有助于回避单一技术的缺陷,分离研究方法对于被试行为的影响,提高研究效度.     

基于贡献原则的幼儿分配公平性

分配公平性是指个体如何以公平的方式对资源进行分配, 其主要依据3个原则：贡献(equity)、平等(equality)和需要(need)。最新研究表明, 幼儿很早就已经具有基于贡献原则的分配公平性判断与行为, 双加工理论对于该研究结果能够给出更为适当的解释, 心理理论与情境卷入水平分别从认知和情绪方面对幼儿分配公平性的发展有着重要影响。未来研究应注重研究内容的具体化, 对幼儿基于贡献原则的分配公平性发展特点、相关影响因素及其内部动机进行深入探究。     

汉语儿童英语和汉语语音意识对英语单词认读的作用

对小学一到三年级81名汉语儿童进行英语、汉语语音意识以及英语单词认读的测试,同时纳入瑞文推理和工作记忆测试作为控制变量,考察英、汉语音意识的不同成分在英语单词认读中的作用。研究结果表明:(1)汉语儿童的英语、汉语语音意识的各个水平与单词认读相关均显著,但不同水平的语音意识对单词认读的影响作用不同。(2)在控制了非言语智力因素和工作记忆的条件下,只有英语、汉语的音位意识对汉语儿童的单词认读具有较强的预测作用。     

工作场所排斥后的应对:期望和效价的作用*

基于期望-效价理论探讨了期望(关系修复可能性)和效价(关系重要性)对工作场所排斥后应对行为的影响。研究1采取回忆范式证实了遭遇工作场所排斥后个体将以积极、消极或不作为行为进行应对,而期望和效价对应对行为有显著预测作用;研究2在研究1基础上,通过情境问卷对期望和效价进行操纵,进一步验证了期望、效价与应对行为之间的因果关系,即关系修复可能性越大、关系越重要,个体越倾向以积极而非消极行为进行应对。
