初中一,二年级学生的亲子冲突

本研究选取北京市两所普通中学１９２名初一和初二学生为被试,通过学生对８个方面亲子冲突的评价,探讨初中生亲子冲突的特点。研究发现,（１）初中生早期的亲子冲突处于较低水平;（２）与母亲的冲突多于与父亲的冲突,女生尤其如此;（３）多数亲子冲突随年级而增加;（４）在多数冲突上,男生与父母的冲突多于女生;（５）亲子冲突最多的三个方面为日常生活安排、学业和家务,而冲突最少的为隐私。     

Acculturation,Economic Stress,Social Relationships and School Satisfaction Among Migrant Children in Urban China

Rural to urban migration has become a prominent phenomenon in China. In linking migration to children’s school trajectories, this mixed-methods study explored a range of cultural and contextual factors that contribute to Chinese children’s school wellbeing in the migratory process. The key variables included acculturative attitudes, economic stress, and relationships with family, teachers and peers. The study drew upon survey data from a sample of 301 Chinese migrant students (4th–9th grade) together with in-depth interviews involving ten selected students focusing on how migrant children’s school happiness and productivity are influenced by acculturation, economic hardship, and social relationships. The quantitative analysis indicated the critical role of integrative states in promoting school satisfaction and achievement. Migrant children with better social relations scored higher levels of hope, which in turn contributed to better school outcomes. Contrary to previous findings, economic stress did not hinder school outcomes for these Chinese migrant children, but appeared to act as a positive motivational factor for pursing academic success. The qualitative analysis echoed the quantitative findings, and provided further explanations for the complexity and particularity of these phenomena.     

Culture and the Structure of Affect: A Bifactor Modeling Approach

This paper tested the impact of culture on the basic structure of affect. It examined positive affect and negative affect at three levels of activation in the U.S. and China. It used a well-suited tool, the bifactor model, to separate the common variance shared by all types of affect from the variance unique to each. The findings indicate that the structure of affect is different cross-culturally. In the U.S., the most fundamental dimension is defined by moderate activation of positive affect and negative affect, which is the largely bipolar dimension of pleasure-displeasure, whereas in China, it is defined by moderate activation of positive affect only, which is pleasure. In both cultures, negative affect across levels of activation forms another important dimension. Beyond these basic dimensions, secondary dimensions are also identified in both cultures: high activation positive affect, low activation positive affect, and low activation negative affect. They form relatively weak unique factors, independent of the two basic dimensions, suggesting that they are largely mixtures of the basic dimensions.     

Common magnitude representation of fractions and decimals is task dependent

Although several studies have compared the representation of fractions and decimals, no study has investigated whether fractions and decimals, as two types of rational numbers, share a common representation of magnitude. The current study aimed to answer the question of whether fractions and decimals share a common representation of magnitude and whether the answer is influenced by task paradigms. We included two different number pairs, which were presented sequentially: fraction–decimal mixed pairs and decimal–fraction mixed pairs in all four experiments. Results showed that when the mixed pairs were very close numerically with the distance 0.1 or 0.3, there was a significant distance effect in the comparison task but not in the matching task. However, when the mixed pairs were further apart numerically with the distance 0.3 or 1.3, the distance effect appeared in the matching task regardless of the specific stimuli. We conclude that magnitudes of fractions and decimals can be represented in a common manner, but how they are represented is dependent on the given task. Fractions and decimals could be translated into a common representation of magnitude in the numerical comparison task. In the numerical matching task, fractions and decimals also shared a common representation. However, both of them were represented coarsely, leading to a weak distance effect. Specifically, fractions and decimals produced a significant distance effect only when the numerical distance was larger.

再探框架对风险决策行为的影响

期望理论运用Ｓ状的价值函数和非线性的权重函数来解释和预测框架效应。“齐当别”抉择模型将不同框架下的抉择行为简单地看成是“最好可能结果之间的取舍”或者“最坏可能结果之间的取舍”。本研究设计了一“匹配”技术,并用此对作者所报告过的支持框架效应与不支持框架效应的选择问题加以再检验。实验表明,采用不同的框架并不能预测性地决定不同的抉择偏爱,而匹配结果所示的“齐当别”策略则能更好地对所收集到的有关框架效应的数据作出解释。     

错认总比错过好——面孔视错觉的发生机制及其应用

面孔视错觉现象表现为个体从其他事物中感知到并不存在的面孔。面孔视错觉要素已广泛应用于艺术、广告及商品中,起到吸引注意、促进消费的作用。同时,先前的研究通过采用各种范式,发现患者在面孔视错觉的产生上同常人的差异,以及视错觉与视幻觉之间的联系。根据视觉加工通路的不同,相关范式可分为视错觉监测范式,以及视错觉辨认范式。前者侧重于基于提取的类面孔特征所做出的快速预测,后者侧重于主观期望引导个体对物体特征的提取,两者最终均会影响到后续的认知判断。日后研究可从面孔视错觉的发生机制出发,结合自上而下和自下而上两种加工通路,为面孔视错觉产生机制提供理论依据,并拓宽该要素在临床诊断及商业广告领域上的应用。     

5·12汶川地震后灾区教师主观幸福感的变化趋势及中介效应分析

·12汶川地震发生两个月后,对508名灾区的幼儿园、中小学教师进行测量,结合他们对地震前状况的回忆,考察其地震后主观幸福感的变化情况及其影响因素。结果表明：（1）与回忆得到的地震前感受相比,地震后灾区教师体验到主观幸福感水平显著降低。（2）极重灾区教师体验到的主观幸福感降低程度大于重灾区和轻灾区教师。（3）教师遭受的客观损失严重程度能显著预测其体验到的主观幸福感降低;而创伤后身心症状在其中起完全中介的作用,即创伤事件引发教师创伤后身心症状,而这些症状日趋严重,使其体验到的消极情感增加、主观幸福感降低。
