Action-state orientation and the theory of planned behavior: A study of job search in China

Job search is an important element of people’s careers and is especially critical for unemployed individuals. The current study surveyed a sample of 328 unemployed job seekers in China to test hypotheses related to the theory of planned behavior and action-state orientation theory. Results of the three-wave longitudinal study demonstrated that the theory of planned behavior was effective in modeling job-search intention and job-search intensity. Action-state orientation moderated the relationship between attitude and intention, as well as the relationship between intention and intensity. The current study sheds light on the motivational and self-regulatory process of job search and reemployment for Chinese unemployed job seekers.     

高中文理分科及学生认知方式对阅读理解影响的实验研究

以高中二年级学生为被试,探讨文理分科、不同认知方式的学生对不同体裁文章及对文章不同信息加工层次的学习效果的影响。结果表明,（1）文理分科、学生认知方式对学生阅读成绩的影响不显著;（2）从总体上看,学生对不同体裁的文章学习效果不同,对说明文的学习明显优于对散文的学习;在文章不同信息的加工层次上,学生对细节的记忆优于对结构的把握;（3）对于不同体裁的文章,学生在信息加工层次上存在差异,对散文的细节记忆好于对结构的把握,对说明文的结构把握好于对细节的记忆。

Cerebral White Matter Integrity and Cognitive Aging: Contributions from Diffusion Tensor Imaging

The integrity of cerebral white matter is critical for efficient cognitive functioning, but little is known regarding the role of white matter integrity in age-related differences in cognition. Diffusion tensor imaging (DTI) measures the directional displacement of molecular water and as a result can characterize the properties of white matter that combine to restrict diffusivity in a spatially coherent manner. This review considers DTI studies of aging and their implications for understanding adult age differences in cognitive performance. Decline in white matter integrity contributes to a disconnection among distributed neural systems, with a consistent effect on perceptual speed and executive functioning. The relation between white matter integrity and cognition varies across brain regions, with some evidence suggesting that age-related effects exhibit an anterior–posterior gradient. With continued improvements in spatial resolution and integration with functional brain imaging, DTI holds considerable promise, both for theories of cognitive aging and for translational application.     

抗震救灾官兵心理健康状况及相关因素分析

了解参加抗震救援官兵的心理健康状况及相关因素,为进行心理危机干预提供科学依据。方法 采用症状自评量表（SCL-90）、简易应对方式问卷（SCSQ）、艾森克人格问卷简式量表中国版（EPQ-RSC）及军事应激症状核查表（PCL-M）,对空军某部抗震救援官兵进行心理测评。结果 消极应对和PCL-M总分与SCL-90总分及各因子分呈正相关（p＜0.01）;积极应对方式与PCL-M总分、SCL-90总分及4项因子分呈低相关（p＜0.01）;不同气质类型PCL-M总分及SCL-90各项统计指标之间均有显著性差异（p＜0.01）。结论 气质类型与应对方式对心理健康状况有很大影响,个别官兵应及时给予心理疏导

Non‐linear structural equation models with correlated continuous and discrete data

Structural equation models (SEMs) have been widely applied to examine interrelationships among latent and observed variables in social and psychological research. Motivated by the fact that correlated discrete variables are frequently encountered in practical applications, a non‐linear SEM that accommodates covariates, and mixed continuous, ordered, and unordered categorical variables is proposed. Maximum likelihood methods for estimation and model comparison are discussed. One real‐life data set about cardiovascular disease is used to illustrate the methodologies.     

Intergroup trust and reciprocity in strategic interactions: Effects of group decision-making mechanisms

I examined the impact of the consensus-making mechanism, where members reach a common decision via an intra-group discussion, on intergroup trust and reciprocity in a strategic setting. Data from a trust game generated the following results. First, compared to individual decision-makers, consensus groups exhibited (a) lower psychological trust, (b) higher behavioral trust, after controlling for psychological trust, and (c) lower reciprocity. Second, compared to decisions made by group-representatives, who are responsible for unilateral decisions on behalf of their groups, group consensus decisions were more trusting but less reciprocating. Thus, the specific decision-making mechanism adopted by groups in a strategic interaction may profoundly change the nature and the interplay of the interaction. Lastly, results show that the level of behavioral trust is driven by reciprocity expectations, while the level of reciprocity behavior, measured as a proportion of the trust received, does not change systematically with the level of trust experienced.     

应对策略和社会支持对提高哮喘患者生活质量的作用

探讨应对策略及社会支持在心理干预对哮喘患者生活质量提高中的作用。采用随机对照的方法,将374名哮喘患者分为实验组（228人）及对照组（146人）,实验组除进行常规的药物治疗外,配合以系统的心理干预方法。选用生活质量问卷、医用应对问卷及社会支持评定量表对治疗前后的生活质量状况、应对策略及社会支持水平进行测量。治疗后,在生活质量总分及各维度、社会支持总分以及对社会支持的利用度上,实验组和对照组得分都有所提高．但实验组提高的分值要显著大于对照组;在回避应对上,实验组和对照组都有所降低,但对照组的降低程度要显著大于实验组,在屈服应对上,实验组和对照组也都有所降低,但实验组的降低程度要显著大于对照组。多元逐步回归分析的结果显示,屈服的降低和对社会支持利用度的提高能够显著预测哮喘患者生活质量的提高。
