The modulation of semantic transparency on the recognition memory for two-character Chinese words

This study demonstrated that semantic transparency as a linguistic property modulates the recognition memory for two-character Chinese words, with opaque words (i.e., words whose meanings cannot be derived from constituent characters—e.g., “光[/guang/, light]棍[/gun/, stick]”, bachelor) remembered better than transparent words (i.e., words whose meanings can be derived from constituent characters—e.g., “茶[/cha/, tea]杯[/bei/, cup]”, teacup). In Experiment 1, the participants made lexical decisions on transparent words, opaque words, and nonwords in the study and then engaged in an old/new recognition test. Experiment 2 employed a concreteness judgment as the encoding task to ensure equivalent semantic processing for opaque and transparent words. In Experiment 3, the neighborhood size of the two-character words was manipulated together with their semantic transparency. In all three experiments, opaque words were found to be better remembered than transparent words. We concluded that the conceptual incongruence between the meanings of a whole word and its constituent characters made opaque words more distinctive and, hence, better remembered than transparent words.     

P16、CyclinDl和CDK4在结直肠癌组织中表达及意义

细胞周期过程中癌基因的激活与抑癌基因的失活等是造成细胞恶性增殖、转化的重要因素。细胞周期G1／S期各调节因子的异常改变与细胞癌变关系尤为密切。P16、CyclinDl和CDK4均为重要的细胞周期调控蛋白,任何原因导致这些蛋白异常表达时,将引起细胞周期调节失控,导致肿瘤的发生和恶性演进。结直肠癌的发生发展同上述三者关系密切。本实验通过免疫组化方法进行检测结直肠癌组织中P16、CyclinDl和CDK4三者的表达及其与结直肠癌临床指标的关系,为揭示三者在结直肠癌发生发展中的作用提供一定的实验依据。     

Maternal Expressed Emotion in Relation to Child Behavior Problems: Differential and Mediating Effects

Maternal expressed emotion (EE), including maternal criticism and emotional over-involvement, is considered an index of family emotional climate that is critical for children’s psychological well-being. Limited research investigates how each element of EE differentially contributes to child behavior problems, or explores the mechanisms, such as child emotion dysregulation, through which parental EE influences child psychosocial outcomes. This study examined maternal EE, child emotion dysregulation, and child behavior problems among 60 mother–child dyads from a community sample, utilizing multi-method and multi-reporter assessment. Findings indicated that maternal expressed criticism toward the child was positively associated with child externalizing symptoms through its relation to increased child emotion dysregulation, whereas maternal emotional over-involvement was negatively associated with child externalizing symptoms through its negative relation to child emotion dysregulation. These results provided increased support for a model in which maternal criticism remains negatively associated with child psychosocial outcomes, but the construct of emotional over-involvement is not necessarily associated with youth psychosocial problems. This study also illustrated one pathway through which maternal EE influence child psychosocial functioning, thus placing EE research in the broader context of research on family emotion socialization.     

大学生心理资本对求职绩效的影响:积极求职行为的中介效应

文章旨在检验心理资本对大学生求职绩效的影响及积极求职行为在两者关系的中介效应.采用配对调查方法,通过152对样本数据(心理资本由两位室友他评,积极求职行为和求职绩效由被试自评)的二元logistic回归和层次回归分析结果显示,心理资本对大学生求职绩效(求职表现满意度、找到工作与否、就业单位满意度)具有显著的正向作用,而积极求职行为在两者关系中起到了部分中介作用.具体而言,心理资本中的事务型心理资本(自信勇敢、乐观希望、奋发进取与坚韧顽强)和积极求职行为中的招聘信息搜寻是影响求职绩效的两个最重要因素.     

New understanding of the role of coincidence site lattice boundaries in abnormal grain growth of aluminium alloy

The sequential microstructure evolution of abnormal grain growth (AGG) in the aluminium alloy (AA5052) was investigated to analyse the migration behaviour of coincidence site lattice (CSL) boundaries, which are known to play an important role in inducing AGG. The sequential evolution showed that CSL boundaries tend to disappear more slowly than general boundaries at the growth front of abnormally growing grains. Especially, the migration rate of Σ9 boundaries was noticeably low, which is contrary to the previous suggestions.     

Fragility of Happiness Beliefs Across 15 National Groups

The belief that happiness is fragile—that it is fleeting and may easily turn into less favourable states—is common across individuals and cultures. However, not much is known about this belief domain and its structure and correlates. In the present study, we use multigroup confirmatory factor analysis and multilevel modelling to investigate the measurement invariance, cross-level isomorphism, predictive validity, and nomological network of the fragility of happiness scale across 15 nations. The results show that this scale has good statistical properties at both individual and cultural levels, and is associated with relevant psycho-social concepts in expected directions. The importance of the results, limitations, and potential directions for future research are discussed.     

The World at 7:00: Comparing the Experience of Situations Across 20 Countries

The purpose of this research is to quantitatively compare everyday situational experience around the world. Local collaborators recruited 5,447 members of college communities in 20 countries, who provided data via a Web site in 14 languages. Using the 89 items of the Riverside Situational Q‐sort (RSQ), participants described the situation they experienced the previous evening at 7:00 p.m. Correlations among the average situational profiles of each country ranged from r = .73 to r = .95; the typical situation was described as largely pleasant. Most similar were the United States/Canada; least similar were South Korea/Denmark. Japan had the most homogenous situational experience; South Korea, the least. The 15 RSQ items varying the most across countries described relatively negative aspects of situational experience; the 15 least varying items were more positive. Further analyses correlated RSQ items with national scores on six value dimensions, the Big Five traits, economic output, and population. Individualism, Neuroticism, Openness, and Gross Domestic Product yielded more significant correlations than expected by chance. Psychological research traditionally has paid more attention to the assessment of persons than of situations, a discrepancy that extends to cross‐cultural psychology. The present study demonstrates how cultures vary in situational experience in psychologically meaningful ways.     

The Cognitive Social Network in Dreams: Transitivity,Assortativity, and Giant Component Proportion Are Monotonic

For five individuals, a social network was constructed from a series of his or her dreams. Three important network measures were calculated for each network: transitivity, assortativity, and giant component proportion. These were monotonically related; over the five networks as transitivity increased, assortativity increased and giant component proportion decreased. The relations indicate that characters appear in dreams systematically. Systematicity likely arises from the dreamer's memory of people and their relations, which is from the dreamer's cognitive social network. But the dream social network is not a copy of the cognitive social network. Waking life social networks tend to have positive assortativity; that is, people tend to be connected to others with similar connectivity. Instead, in our sample of dream social networks assortativity is more often negative or near 0, as in online social networks. We show that if characters appear via a random walk, negative assortativity can result, particularly if the random walk is biased as suggested by remote associations.     

Your own face is no more precious than others’: Evidence from the simultaneous–sequential paradigm

In the present study, we tested the dominant notion that the processing of familiar faces takes place in an automatic, capacity-unlimited manner. To do so, we had participants perform the task of detecting their own face among others’ nonfamiliar faces. Importantly, either all of the search stimuli were presented simultaneously or two different subsets of the stimuli were presented sequentially. The results showed that the search performance benefited from sequential presentation, indicating that detecting one’s own face depends on a capacity-limited process. A similar pattern of results was found when participants searched for someone else’s face, although there was a decline in the overall performance. These findings suggest that the processes of detecting familiar and unfamiliar faces suffer from the capacity limit of visual perception to similar extents, challenging the notion of the automaticity of familiar-face processing.
