Proactive yet reflective? Materializing proactive personality into creativity through job reflective learning and activated positive affective states

Studies linking proactive personality to creativity have primarily taken a future-oriented perspective, describing a process where individuals assess future opportunities and risks of creative endeavors. Complementing this approach, we draw on an attribution theory perspective to delineate how proactive personality relates to employee creativity through the serial mediating effects of job reflective learning—a backward-looking cognitive process—and activated positive affective states. Job reflective learning captures backward-looking self-assessments and the underlying internal causal attributions, and it is differentiated into two valences: job reflective learning from successes and from failures. Based on two separate multi-wave, multi-source field studies, our findings consistently show a serial mediation process linking proactive personality to creativity through both valences of job reflective learning and activated positive affective states. Job reflective learning from successes breeds joviality, whereas job reflective learning from failures arouses attentiveness. Joviality and attentiveness—both types of activated positive affective states—in turn promote creativity. We discuss the theoretical and practical implications of how proactive employees manifest their proactivity trait into actual creativity through backward-looking cognitive and affective processes.     

一种新的等值准则及其适用范围的探讨

受假设检验方法的启发,该文引出了一种基于项目反应理论的新等值方法——平方根等值准则。它具有一些特点：定义式中答对、答错概率同时出现而不能互相替代;极易从0—1评分模式的版本转换到多级评分版本;它可以看成是Haebara等值准则的加权形式。以等值系数估计值的误差大小为衡量标准,以Wilcoxon符号秩检验为依据,大量的Monte Carlo模拟结果显示了一种有趣的现象,即等值方法的运用范围既与项目参数估计精度有关,又与等值系数A的范围有关,但与另一个等值系数B的范围无关。当项目参数估计精度较高或中等而A取值在0.9～1.3之间,新方法往往比Stocking_Lord方法和Haebara方法的估计误差小且有显著性差异,当项目参数估计精度较低时,而A从1.0～2.0时新方法都有优越性。     

普通话测试的录音评分可行性、信度及经济效率

该研究采用心理测量中的概化(generalizability theory)理论,通过两个研究,分析国家语言文字工作委员会的普通话测试中采用录音评分的可行性,并探讨了其信度、经济效率及心理测量等特性。研究共有25名被试及8名评分员。结果表明录音评分和现场评分测试的结果是一致的,最少能区分90％的能力差异。此外,研究亦指出现行测试的评分者人数及题数已经算足够,但仍可依考生能力特性等,作一些调整以提高测试效率。     

《中学生课堂情境兴趣问卷》的信效度检验及应用

以300名高中生为被试,采用问卷法,检验了《中学生课堂情境兴趣问卷》的信、效度,并考察了中学生课堂情境兴趣的特点。结果发现：（1）《中学生课堂情境兴趣问卷》具有较好的信、效度指标,是测量中学生课堂情境兴趣的一个有用工具。（2）中学生在英语、数学与语文课堂情境兴趣上,不存在显著性别差异。（3）中学生在英语、数学与语文课堂情境兴趣上存在年级差异,随年级升高,英语、语文课堂情境兴趣逐渐降低,数学课堂情境兴趣逐渐上升。     

关于网络成瘾的心理学研究

网络成瘾指一种心理上对网络的依赖,其概念与药物成瘾既有相似又有差异。目前还缺乏编制精良、应用广泛的测量工具。多数研究采用调查的方法,严格的实验研究很少。一些研究者提出理论模型从心理层面对其进行解释,其中具代表性的有：Young提出的ACE模型,Davis的认知-行为模型,以及Grohol的阶段模型,分别探讨了网络依赖的发生与网络的致瘾特征,网络用户的个体特质以及外在环境之间的关系。     

Signaling Mechanisms Mediating BDNF Modulation of Synaptic Plasticity in the Hippocampus

Although recent studies indicate that brain-derived neurotrophic factor (BDNF) plays an important role in hippocampal synaptic plasticity, the underlying signaling mechanisms remain largely unknown. Here, we have characterized the signaling events that mediate the BDNF modulation of high-frequency synaptic transmission. Mitogen-associated protein kinase (MAPK), phosphotidylinositol-3 kinase (PI3K), and phospholipase C-γ (PLC-γ) are the three signaling pathways known to mediate neurotrophin signaling in other systems. In neonatal hippocampal slices, application of BDNF rapidly activated MAPK and PI3K but not PLC-γ. BDNF greatly attenuated synaptic fatigue at CA1 synapses induced by a train of high-frequency, tetanic stimulation (HFS). Inhibition of the MAPK and PI3K, but not PLC-γ, prevented the BDNF modulation of high-frequency synaptic transmission. Neurotrophin-3 (NT-3), a close relative of BDNF, did not activate MAPK or PI3K and had no effect on synaptic fatigue in the neonatal hippocampus. Neither forskolin, which activated MAPK but not PI3 kinase, nor ciliary neurotrophic factor (CNTF), which activated PI3K but not MAPK, affected HFS-induced synaptic fatigue. Treatment of the slices with forskolin together with CNTF still had no effect on synaptic fatigue. Thus, although the activation of MAPK and PI3K is required, the two together are not sufficient to mediate the BDNF effect. Inhibition of new protein synthesis by anisomycin or cycloheximide did not prevent the BDNF effect. These data suggest that BDNF modulation of high-frequency transmission is independent of protein synthesis but requires MAPK and PI3K and yet another signaling pathway to act together in the hippocampus.

人际关系对青少年道德思维方式的影响*

为考察人际关系对不同年龄段青少年道德思维方式的影响,以机车道德两难困境为材料,采用2（计划路线受害者：亲人、陌生人）×2（非计划路线受害者：亲人、陌生人）×4（年级：小学、初中、高中、大学）被试间实验设计。结果发现,计划路线受害者和非计划路线受害者人际关系的交互作用显著,计划路线受害者为陌生人时,被试在非计划路线受害者为亲人时采用规则导向的思维方式,陌生人时则采用结果导向的思维方式;当非计划路线受害者为亲人时,被试在计划路线受害者为亲人时采用结果导向的思维方式,陌生人时采用规则导向的思维方式。年级与计划路线受害者的交互作用显著。研究支持了道德社会关系规则理论,个体的道德思维方式受到道德情境中人际关系的影响。人际关系对青少年道德思维方式的影响随着年级升高而增强,转折点在初二与高二之间。
