青少年学生焦虑敏感与睡眠质量的关系及其内在机制

采用中学生、大学生焦虑敏感问卷和匹兹堡睡眠质量指数量表(PSQI),分别对1011名中学生和607名大学生进行调查。结果显示高焦虑敏感学生的PSQI总分显著高于低焦虑敏感学生,焦虑敏感及其三个因子与PSQI的相关都是中效应,焦虑敏感对青少年学生睡眠质量指数具有显著的正向预测作用,焦虑敏感水平越高,其睡眠质量越差。焦虑敏感可能以应激事件和健康问题作为致敏源,以焦虑等负性情绪作为敏感内容,在消极自动认知觉察与思维的介入下,进一步放大对有关负性情绪的感受与体验,从而影响青少年学生的睡眠质量。     

Reliability and concurrent validation of the IPIP Big-Five factor markers in China: Consistencies in factor structure between Internet-obtained heterosexual and homosexual samples

Previous studies have suggested the cross-cultural generalizability of a 5-factor structure for personality traits. In this article, we analyzed the utility of 2 versions (100-item and 50-item) of the IPIP Big-Five factor markers in both heterosexual (N = 633) and homosexual (N = 437) samples in China. Factor analysis within versions showed that both versions of these IPIP measures showed clear 5-factor orthogonal structures that were nearly identical to the American structure in both subject samples. The reliabilities of the five factors were quite high except for the 50-item measure of Agreeableness. The part-whole correlations between the 100-item and 50-item factors were high, as were the factor congruence coefficients between the heterosexual and the homosexual samples. Both versions of the IPIP Big-Five factor markers were strongly correlated with the scales from the Big-Five Inventory (BFI: John, Donahue, & Kentle, 1991), thus providing some concurrent validation in a Chinese context.     

不良生活方式形成的原因探析

不良生活方式是慢性病的主要危险因素。生活方式应当既包括生活活动,又包括生产活动,是一种连续的行为。不良生活方式具有自创性、社会性、播散性和可改变性。健康生活方式具有主动性、高尚性、和谐性、适宜性和健康有利性。不良生活方式产生的原因主要有生活目的需求和动机的错位,人格缺陷,社会压力与从众心理,无知及社会的变迁等。     

不良生活方式作用途径及其控制

不良生活方式影响健康的途径包括：病从口入;生活放纵造成机体的衰竭;享受型生活方式“废用”性的机体退化;生活中的失慎与失范导致直接的伤亡;生活压力导致的机体受损;挑战生理极限的心理、生理代价．改变不良生活方式应当遵从科学的原则和一定的标准。     

不同记忆提取条件下的自我参照效应

通过操纵记忆提取的条件,本实验比较了自我参照、他人参照和无参照(褒义/贬义)任务下的记忆效果.结果发现:(1)自我参照编码在再认测验中出现了显著的提取优势(F(2.41)=6.097,p<0.01);(2)自我参照编码在颜色一致/不一致判断中未出现显著的提取优势(F(2,41)=1.039,p=0.363);(3)再认测验中,颜色不一致旧词的再认辨别力高于一致条件(F(1,41)=3.139,p=0.084).     

Core information processing deficits in developmental dyscalculia and low numeracy

There are two different conceptions of the innate basis for numerical abilities. On the one hand, it is claimed that infants possess a 'number module' that enables them to construct concepts of the exact numerosities of sets upon which arithmetic develops (e.g. Butterworth, 1999; Gelman & Gallistel, 1978). On the other hand, it has been proposed that infants are equipped only with a sense of approximate numerosities (e.g. Feigenson, Dehaene & Spelke, 2004), upon which the concepts of exact numerosities are constructed with the aid of language (Carey, 2004) and which forms the basis of arithmetic (Lemer, Dehaene, Spelke & Cohen, 2003). These competing proposals were tested by assessing whether performance on approximate numerosity tasks is related to performance on exact numerosity tasks. Moreover, performance on an analogue magnitude task was tested, since it has been claimed that approximate numerosities are represented as analogue magnitudes. In 8-9-year-olds, no relationship was found between exact tasks and either approximate or analogue tasks in normally achieving children, in children with low numeracy or in children with developmental dyscalculia. Low numeracy was related not to a poor grasp of exact numerosities, but to a poor understanding of symbolic numerals.     

元认知的调节过程及其领域一般性问题的分析

元认知是个体对自身认知的动态的调节活动.该文界定了元认知调节的六个基本过程,总结了常见的研究范式,并着重探讨了元认知调节领域一般性的研究结果.大多数结果支持元认知调节的领域一般性;但随着认知任务带来的心理负荷程度不同,元认知调节活动也会表现出一定的领域特殊性.研究者提出,通过比较元认知调节过程在不同领域的变化或发展趋势,可以从另一个角度来探讨元认知调节的领域一般性问题.     

When we feel good and bad about ourselves: self-esteem memories across cultures

Young adults in the United States, Croatia, and China described personal episodes of times when they felt especially good or bad about themselves. These self-esteem memories were either recent (episodes that occurred during the previous 4 weeks) or remote (episodes that occurred between the ages of 10 and 15). Systematic content differences between memories of positive and negative self-worth were apparent primarily for remote rather than for recent memories. Across cultures, long-lasting positive memories frequently represented achievement themes, whereas negative memories frequently represented social themes. Links between achievement success and positive self-regard, and between social distress and negative self-regard, are explained using theories of self-esteem and autobiographical memory.     

The psychology behind the masks: Psychological responses to the severe acute respiratory syndrome outbreak in different regions

Severe acute respiratory syndrome (SARS) was first reported in China, and spread to 29 regions, affecting over 8000 people worldwide. For the general public, the psychological impact of SARS may have been greater than the physical health danger of the disease. The present paper proposes the influence of psychological factors on people's cognitive, affective, and behavioral responses during the SARS outbreak. The various papers in this special issue of the Journal reveal how people have reacted during the SARS outbreak: People's general coping styles may be related to their health behavior during the outbreak. Cultural differences were evident in the perception of SARS, and individuals' perceptual styles may have influenced their ability to cope with the outbreak. The way in which individuals coped with SARS-related stressful events was different from their usual practices of managing daily stress. Individual differences in the adoption of preventive measures were related to the distinct susceptibility to several social-cognitive biases.
