Extraversion modulates functional connectivity hubs of resting‐state brain networks

Personality dimension extraversion describes individual differences in social behaviour and socio‐emotional functioning. The intrinsic functional connectivity patterns of the brain are reportedly associated with extraversion. However, whether or not extraversion is associated with functional hubs warrants clarification. Functional hubs are involved in the rapid integration of neural processing, and their dysfunction contributes to the development of neuropsychiatric disorders. In this study, we employed the functional connectivity density (FCD) method for the first time to distinguish the energy‐efficient hubs associated with extraversion. The resting‐state functional magnetic resonance imaging data of 71 healthy subjects were used in the analysis. Short‐range FCD was positively correlated with extraversion in the left cuneus, revealing a link between the local functional activity of this region and extraversion in risk‐taking. Long‐range FCD was negatively correlated with extraversion in the right superior frontal gyrus and the inferior frontal gyrus. Seed‐based resting‐state functional connectivity (RSFC) analyses revealed that a decreased long‐range FCD in individuals with high extraversion scores showed a low long‐range functional connectivity pattern between the medial and dorsolateral prefrontal cortex, middle temporal gyrus, and anterior cingulate cortex. This result suggests that decreased RSFC patterns are responsible for self‐esteem, self‐evaluation, and inhibitory behaviour system that account for the modulation and shaping of extraversion. Overall, our results emphasize specific brain hubs, and reveal long‐range functional connections in relation to extraversion, thereby providing a neurobiological basis of extraversion.     

Influence of plastic strain localisation on the mechanical properties of metal matrix composites

The aim of the present study is to reveal the most critical underlying factor influencing the mechanical properties of metal matrix composites (MMCs). It is shown that the mechanical properties of MMCs are essentially governed by the degree of strain localisation during plastic deformation. In other words, the MMCs exhibit superior mechanical performance only if the strain localisation is obviously inhibited and the accumulated stresses can be effectively transferred out. The work provides a new perspective in guiding the design of next-generation high-performance MMCs by suppressing the strain localisation as far as possible.

Measuring the personality of Chinese: QZPS versus NEO PI-R

The response patterns of Chinese subjects to the items and facets of NEO Personality Inventory Revised (NEO PI-R) were investigated. The Big Five-factor structure underlying this instrument was not found, while a seven-factor structure, more recently proposed to represent the Chinese personality, emerged. A cross-cultural strategy was adopted to analyze these results and mechanisms through which culture influences personality, behavioral categories and specific behaviors were proposed. The results showed that the Big Seven model of Chinese personality was stable and Western personality questionnaires could not accurately measure the personality characteristics of the Chinese.     

中国人人格七因素量表(QZPS-SF)的信度与效度

本研究的目的是依据中国人人格量表（QZPS）编制一份能够迅速测查人格七个维度的短式七因素量表（QZPS—SF）。根据6000余名被试对QZPS的215个项目的评定分数,通过因素分析确定了七个因素、与QZPS的七个因素对应构成了QZPS—SF。通过被试的自我评定以及他人评定和特殊群体被试（精神分裂症病人、吸毒者以及罪犯）的人格特点比较,显示了QZPS—SF有着良好的信度和效度。文中还对QZPS—SF的应用范围以及注意事项进行了讨论。     

孔孟德性思想及其现代价值

孔孟思想是典型的德性伦理思想,孔孟德性思想是一个以"仁"为核心,主要包括恭、宽、信、敏、惠和仁、义、礼、智、信等德目的思想体系,其内容广泛,涉及人类社会生活的各个领域,对中国几千年的思想文化产生了深远影响。当今社会,在经济飞速发展、社会生活发生巨大变化的背景下,孔孟德性思想是现代社会融洽人际关系、建立良好社会秩序的思想基础,是提升个体生命质量、应对现代社会挑战的自律武器,是增强民族凝聚力、博大民族情怀的心理根基。     

声旁与笔画省略方式对形声字识别的影响

本研究通过两个实验,考察笔画省略方式和声旁对形声字识别的影响。实验一采用命名任务考察了声旁和三种笔画省略方式（省前、略后、不省）对左右结构形声字识别的影响。结果表明存在笔画顺序效应和声旁位置效应,并发现略后的笔画中有声旁,笔画顺序效应会消失。这说明声旁的作用抵消了笔画顺序效应,体现了声旁在形声字识别中的重要作用;实验二在实验一的基础上,采用上下结构的形声字,实验结果表现出了相同的趋势,且更加显著。     

MAOA基因与抑郁的关系

抑郁的发生具有遗传基础。近年来, 随着分子遗传技术的发展, 对抑郁遗传机制的研究已经深入到分子水平。既有研究表明, MAOA基因在抑郁的发生发展中发挥着十分重要的作用。MAOA基因与抑郁间存在紧密的直接关联, 而且MAOA基因与环境及其他基因亦交互作用于抑郁, 然而, 既有相关研究结论尚存分歧。未来研究应更加关注MAOA基因与多种环境因素及其它基因间的复杂交互作用, 考察MAOA基因的年龄效应, 揭示MAOA基因作用于抑郁的脑机制。
