The Effect of Conflict Goals on Avoidance Strategies: What Does Not Communicating Communicate?

Avoidance is proposed to be a goal‐directed behavior rather than a behavior that reflects passivity or inaction. To evaluate this proposition, a typology of conflict goals and a typology of conflict avoidance strategies are created, and the relationship between nonavoidance strategies and the elements of these 2 typologies are evaluated within a structural equation model (N = 352). Findings show that, except for pretending and withdrawal, conflict goals successfully predict avoidance strategies, thereby affirming their strategic importance. The article concludes by addressing areas for future research, including modifications and refinement of the typologies and proposing other strategies and goals that may be theoretically significant.     

A Two-Tier Full-Information Item Factor Analysis Model with Applications

Motivated by Gibbons et al.’s (Appl. Psychol. Meas. 31:4–19, 2007) full-information maximum marginal likelihood item bifactor analysis for polytomous data, and Rijmen, Vansteelandt, and De Boeck’s (Psychometrika 73:167–182, 2008) work on constructing computationally efficient estimation algorithms for latent variable models, a two-tier item factor analysis model is developed in this research. The modeling framework subsumes standard multidimensional IRT models, bifactor IRT models, and testlet response theory models as special cases. Features of the model lead to a reduction in the dimensionality of the latent variable space, and consequently significant computational savings. An EM algorithm for full-information maximum marginal likelihood estimation is developed. Simulations and real data demonstrations confirm the accuracy and efficiency of the proposed methods. Three real data sets from a large-scale educational assessment, a longitudinal public health survey, and a scale development study measuring patient reported quality of life outcomes are analyzed as illustrations of the model’s broad range of applicability.     

The Trajectory of Counseling in China: Past,Present, and Future Trends

This article surveys the past, present, and future trends of counseling in China. Historically, mental health problems were addressed within the family. Currently, psychotherapy from trained practitioners is available on a limited basis, at least in urban settings. The challenge of mental health in China is tremendous, and the efforts to meet that challenge are encouraging. The authors recommend that in the future, prevention and intervention services be offered that are ecosystemic, strengths‐based, and culturally appropriate.     

Role of Surface Roughness in Hysteresis during Adhesive Elastic Contact

In experiments that involve contact with adhesion between two surfaces, as found in atomic force microscopy or nanoindentation, two distinct contact force (P) vs. indentation-depth (h) curves are often measured depending on whether the indenter moves towards or away from the sample. The origin of this hysteresis is not well understood and is often attributed to moisture, plasticity or viscoelasticity. Here we report experiments that show that hysteresis can exist in the absence of these effects, and that its magnitude depends on surface roughness. We develop a theoretical model in which the hysteresis appears as the result of a series of surface instabilities, in which the contact area grows or recedes by a finite amount. The model can be used to estimate material properties from contact experiments even when the measured P-h curves are not unique.     

血糖水平对STZ鼠探究行为及学习记忆的影响

为了解不同血糖水平下链脲佐菌素诱导鼠（STZ鼠）探究行为与学习和记忆的变化情况,把60只STZ鼠按血糖水平分成高血糖组、良好血糖组和低血糖组3组,进行延迟时间、探究时间测定和小鼠跳台试验,并与正常对照组比较。结果发现,良好血糖组与正常对照组各检测指标均相近;3组STZ鼠延迟时间、完成迷津作业时间均按血糖值递增;组间差异显著;小鼠跳台试验中高血糖组的错误数最多,24小时后错误数最少,前后差值有组间差异;延迟时间、探究时间与血糖呈显著正相关,错误数差值与血糖呈显著负相关。结果表明,高血糖鼠的探究行为和学习能力最差,但对被动回避学习的记忆保持相对较好。     

大学生创造性内隐观的调查研究——关于高创造性者的特征

本研究采用社会效度的方法,对大学生的创造性内隐观进行了调查研究,结果发现：1．大学生的创造性内隐观所涉及的范围广泛,涵盖了认知、人格的许多方面;2．经因素分析把大学生的创造性内隐观可以概括为十二个因素,分别是：道德品质、才情、异常人格、独创力、探究、自主敢为性、思维发散性、知识经验、勤勉、问题发现、智力、自强,其中道德品质和勤勉为中国大学生所特有。3．不同专业和性别的大学生在上述诸因素上内隐观总体差异显著,并且二者交互作用总体显著,在各具体因素上内隐观有些也存在不一致。     

阿拉伯数字与汉字大写数字认知的大脑功能一侧化实验研究

用半视野速示术检查阿拉伯数字和汉字大写数字在三种任务加工条件（认读、简单相加、奇偶概念异同判断）下进行认知的大脑两半球机能活动一侧化效应。结果表明：以被试正确反应的百分数为指标,两类数字的三种任务加工均没有表现出明显的视野（大脑半球）优势。以被试正确反应的反应时为指标,两类数字的认读和简单相加也未出现视野（大脑半球）的明显差别,而两类数字的奇偶概念异同判断却出现了差异显著的右视野（左半球）优势。
