创造性的公众观的调查研究（Ⅰ）——关于高创造性者的特征

本研究采用凋查分析的方法,在预调查的基础上,编制问卷对创造性的公众观进行了调查研究,结果发现：1．公众认为高创造性者的特征主要涉及认知和人格两个方面。2．公众对高创造性者的特征的认识与专家的认识存在广泛一致,但在广度,深度和具体项目的重要性上存在不少差异。3．不同教育程度的公众对高创造性者的特征的认识总体差异显著．4．公众的性别,年龄,教育程度对高创造性者的特征的认识的某些方面影响显著或非常显著。     

Self‐esteem and culture: Differences in cognitive self‐evaluations or affective self‐regard?

Although people from East Asian countries consistently report lower self-esteem than do those from Western countries, the origins of this difference are unclear. We conducted two studies to illuminate this issue. Study 1 found that Chinese participants appraised themselves less positively than American participants on a cognitive measure of self-evaluations, but cultural differences were absent on a measure of affective self-regard. Moreover, cultural differences in global self-esteem were eliminated once cognitive self-evaluations were statistically controlled. Study 2 found that cultural differences in modesty underlie cultural differences in cognitive self-evaluations. These findings suggest that Chinese feel as positively toward themselves as Americans do, but are less inclined to evaluate themselves in an excessively positive manner.     

Sense of home buffers threats to the self

We hypothesised that sense of home serves as a buffer against self‐threat. In three experiments, we induced sense of home (vs. control) and assessed its buffering function to threat. Sense of home augmented openness to stereotype threat information (Experiment 1), increased performance on a spatial rotation ability test after stereotype threat (Experiment 2), and reduced the desire for high‐status products following mortality salience (Experiment 3). This “proof of concept” research establishes the buffering potential of sense of home and raises theoretical and practical implications.     

A Sociocultural Approach to Narcissism: The Case of Modern China

Using large Internet samples, we examined the possible influence of sociodemographic factors on the Chinese self‐concept and in particular, on the level of narcissism. We found that (i) younger persons are more narcissistic than older ones; (ii) persons from higher socioeconomic classes are more narcissistic than those from lower socioeconomic classes; (iii) persons from only‐child families are more narcissistic than those from families with multiple children; (iv) persons from urban areas are more narcissistic than those from rural areas; and (v) individualistic values are predictive of individual differences in narcissism. The findings suggest that sociocultural changes contribute to the rise of narcissism in China. Copyright © 2011 John Wiley & Sons, Ltd.     

Anomalous ductile-brittle fracture behaviour in fcc crystals

The fracture behaviour of fcc crystals has been investigated by numerically simulating the dynamical failure of a three-dimensional notched crystal using molecular dynamics, simple interatomic potentials for a rare-gas solid and system sizes of about ten million atoms. We find that the solid fails by brittle cleavage for cracking on a {110} face growing in a [110]direction and by ductile plasticity for cracking on a {111} face growing in a [110]direction. Comparison of equilibrium surface energies on the crack face and Schmid factors on the primary slip systems indicates that the classical theories of fracture give predictions in contradiction with the simulation results. A hyperelasticity model is proposed to explain this discrepancy. This anomalous fracture behaviour of fcc crystals has a profound implication on general modelling of dynamic failure of solids.     

How do slender mineral crystals resist buckling in biological materials?

Mineral crystals in biological materials such as bone, tooth, and sea shell are susceptible to buckling under compressive loading due to their slender geometry with large aspect ratios. How does nature deal with this problem? This question is especially interesting in view of the three orders of magnitude difference in elastic modulus between protein and mineral. As a first analysis of this question, we study the stability of a single mineral platelet confined in an otherwise perfect protein–mineral nanostructure. We find that there exists a transition of buckling strength from an aspect ratio-dependent regime to a lower threshold value, independent of the crystal geometry. Typical values of the aspect ratio of mineral crystals of bone and nacre fall in this transition region. The existence of a buckling strength independent of the detailed geometrical parameters of mineral may be critically important from the point of view of structure robustness as the composite behaviour of biomaterials should not depend sensitively on small variations in crystal size and shape.     

未来自我连续性及其对个体心理和行为的影响

一个人将现在自我和未来自我联系在一起的紧密程度反映了他/她在时间维度上自我连续性的强度, 即未来自我连续性。个体如何看待其现在自我与未来自我之间的连续和一致程度对个体的心理和行为有重要的影响, 特别是在跨期决策、储蓄和消费、学业成就领域、社会行为和健康领域等方面。未来研究可深入探讨未来自我连续性的神经基础及其影响因素, 并进一步拓展未来自我连续性相关的应用研究。     

大学生性别自我概念的结构

同时运用外显的自陈式量表和自行设计的内隐联想测验来研究大学生的性别自我概念 ,结果表明 :(1)运用内隐联想测验来测量内隐性别自我概念是可靠、有效、敏感的 ;(2 )在性别自我概念的内隐层面上 ,性别差异十分显著 ;在性别自我概念的外显层面上 ,除了女性正性量表外 ,其他量表上均未表现出显著的差异。 (3)性别自我概念是一个双重的结构 :包括一个内隐的性别自我概念和一个外显的性别自我概念 ,前者是一个一维的未分化的结构 ,后者是一个两维的结构 ,并且二者相对独立     

半个多世纪来中国人的心理与行为变化——心理学视野下的研究

半个多世纪以来, 史无前例的快速社会变迁对中国文化和中国人的心理与行为产生了广泛而深远的影响。现有研究探讨了中国人在十多个方面的心理和行为变化, 包括文化价值、人格特征、自我建构、人际信任、幸福感、情绪、动机、关系、心理健康以及其他社会态度和行为等。总体上, 这些研究勾画出了半个世纪以来中国人心理变化的总体倾向：(1)与现代社会相适应的个体主义价值和心理行为日益盛行; (2)传统社会所强调的集体主义价值虽日渐衰落, 但其部分仍在当代社会主流价值中占有一席之地; (3)多元文化共存将是当下和未来中国社会的重要特征。一些具体的变化还包括：中国人的一般信任在下降、幸福感先下降但近年来有上升的迹象、心理健康总体水平上升但是不同社会群体升降不一致、总体的负性情绪在增加、性观念更为开放和包容等。未来的研究应在广度(内容、领域)和深度(原因、机制和过程)上对现有研究进行拓展, 努力建构能同时解释心理和行为变化一般规律及中国人的变化独特性的理论。
