人类嗓音加工的神经机制——来自正常视力者和盲人的脑神经证据

人类嗓音作为听觉环境的重要组成部分, 包含了大量副语言信息以帮助识别个体身份, 尤其对于盲人而言, 视觉面孔经验的缺乏使得嗓音信息成为其感知对方个体特征的主要来源。通过结合正常视力者和盲人在嗓音选择性加工和嗓音身份加工方面的研究, 尝试揭示普遍的人类嗓音加工模式以及盲人特异的嗓音加工机制。此外, 与视觉面孔加工相关的梭状回脑区也参与并卷入了两类人群的嗓音加工任务, 以此为基础梳理的视听整合模型和基于去掩蔽效应的跨模态重组假说, 为这两类人群嗓音加工神经基础的差异性提供了相应的解释机制, 未来研究希望可以进一步探究盲人的嗓音加工策略, 以及考察左侧颞上沟/回脑区在嗓音加工中的作用。     

Investigation of Psychometric Properties of the Georgian Version of Posttraumatic Growth Inventory

This paper reports the analysis of psychometric properties of the Georgian version of the Posttraumatic Growth Inventory (PTGI-Geo). In particular, factor structure, internal consistency of the subscales, gender differences, and relation between traumatic event category and posttraumatic growth (PTG) are examined. The study had 641 participants in two studies (study 1, n = 300; study 2, n = 341 participants). The study revealed that PTGI-Geo consists of four factors, instead of the original five factors; namely, the first three factors (New Possibilities, Relation to Others, and Personal Strength) remained unchanged, while the fourth (Spiritual Change) and the fifth (Appreciation of Life) factors merged and formed a new fourth factor. All four new factors have similar internal consistency as the original inventory. There were also some between-person differences for gender consistent with other research.     

《中国青少年心理健康素质调查表》的区分效度研究

采用《中国青少年心理健康素质调查表》调查了天津市425名正常和115名有心理问题大学生的心理健康素质,结果表明：正常组大学生的人际素质、个性素质、自我、应对风格和适应等分量表得分都高于有心理问题组大学生且具有显著差异,而动力系统、认知风格、归因风格分量表得分差异不显著。比较分析研究结果说明《中国青少年心理健康素质调查表》在区分正常和有心理问题大学生的心理健康素质方面可靠、有效。     

认知负荷和项目竞争强度对大学生提取诱发遗忘的影响

采用提取练习范式与逐试次刷新任务相结合的双任务对96名大学生进行测试,通过考察认知负荷和项目竞争强度对提取诱发遗忘(RIF)的影响,以澄清RIF的产生机制。结果发现:相对于高、低认知负荷组大学生而言,控制组大学生在高项目竞争强度下诱发出显著的RIF,在低项目竞争强度下则未诱发出显著的RIF。结果表明:控制组大学生在汉语类别-样例词对中产生的RIF是由需要认知资源的控制性抑制加工产生的,这种RIF比拼音类别-样例词对中的RIF需要更多的认知资源,且未受相关代价与效益问题影响。     

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.     

Parent-early adolescent relationship quality and problem behavior in Hungary,the Netherlands,India, and Iceland

Higher parent-child relationship quality has been associated with less internalizing and externalizing problem behavior. However, it remained less clear whether these associations are universal or depend on the country under investigation. Furthermore, fathers are still understudied, even though there is increasing evidence of their important role in early adolescent development. Our study compared the association of mother-child as well as father-child relationship quality with early adolescents’ problem behavior in four culturally different countries, namely Hungary (N = 293; M_age = 11.22; 53% boys), the Netherlands (N = 242; M_age = 11.20; 48% boys), India (N = 230; M_age = 10.68; 61% boys), and Iceland (N = 261; M_age = 10.90; 53% boys). Early adolescents filled out questionnaires in their classroom, assessing warmth and conflict with fathers and mothers and internalizing and externalizing problem behavior. Stepwise multi-group path analysis demonstrated no cross-cultural differences in associations between quality of the parent-child relationship and problem behavior. We did not find any effects of maternal or paternal warmth. However, across samples conflict with mothers was associated with more internalizing and externalizing problem behavior, and conflict with fathers was associated with more externalizing problem behavior. Our findings highlight the need to target conflict with both fathers and mothers in interventions across different countries, especially when addressing externalizing problem behavior.     

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。

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。
