The cross-cultural generalizability of Axis-II constructs: an evaluation of two personality disorder assessment instruments in the People's Republic of China

We examined the reliability, cross-instrument validity, and factor structure of Chinese adaptations of the Personality Diagnostic Questionnaire (PDQ-4+; N = 1,926) and Personality Disorders Interview (PDI-IV; N = 525) in psychiatric patients. Comparisons with data from Western countries suggest that the psychometric properties of these two instruments are comparable across cultures. Low to modest agreement between the PDQ-4+ and PDI-IV was observed for both dimensional and categorical personality disorder evaluations. When the PDI-IV was used as the diagnostic standard, the PDQ-4+ showed higher sensitivity than specificity, and higher negative predictive power than positive predictive power. Factor analyses of both instruments replicated the four-factor structure O'Connor and Dyce (1998) found in Western samples. Results suggested that conceptions and measures of DSM-IV personality disorders are cross-culturally generalizable to Chinese psychiatric populations.     

多级估量法在大学生职业价值观研究中的应用

用模糊数学中的多级估量法对532名大学生的职业价值观进行调查研究,结论如下(1)当代大学生的职业价值观呈现出多元化的特点,在多元化的职业价值体系中,"充分发挥能力"、创造性"、"收入"处于前三位,"地位、名声"、"成长为领导者"、"冒险",处于后三位.(2)用多级估量法不但可以得到用排序法得到的信息,而且可以得到用排序法得不到的更加细致的信息.(3)就整体而言,大学生的职业价值观不因其所在的学校、所学的专业科类、是否临近毕业、性别等因素的不同而不同.就部分而言,上述四大因素都对大学生的某些职业价值项目有一定的影响.     

上下文熟悉效应对元记忆监测和记忆的影响

在认知任务中,伴随编码和检索的外围信息被称为上下文,其本身并不是编码或检索的目标。如果学习时的上下文在其后进行提取时重复出现,不管是否对应之前的学习项目,都会增加个体再认正确的概率。这种由于上下文增强项目熟悉感而促进记忆效果的现象就称为上下文熟悉效应。本研究通过两个实验探究上下文熟悉效应对元记忆监测及记忆的影响机制。其中,元记忆监测是以学习判断和信心判断为指标。记忆成绩则是以再认正确率为指标。研究结果显示:第一,上下文熟悉效应影响元记忆监测:学习判断等级上,恢复条件显著高于新条件,且不受任务难度影响; 信心判断等级上,简单任务时恢复条件与新条件无显著差异,困难任务时恢复条件显著高于新条件。第二,上下文熟悉效应影响记忆成绩:再认成绩上,简单任务时新条件显著高于恢复条件; 困难任务时恢复条件显著高于新条件。研究得出结论:上下文熟悉效应对元记忆监测和记忆都有显著影响,任务难度起调节作用。     

主动性人格对大学生求职行为影响机制的追踪研究

基于求职自我效能感和就业情境压力感知视角,考察主动性人格对大学生求职行为的影响及其作用机制。采用问卷调查法,在珠三角地区6所高校选取1000名大四学生进行为期6个月的追踪测查,对前、后侧均参加调查的658名被试数据进行统计分析。结果表明:主动性人格对求职行为具有显著的正向促进作用;求职自我效能感在主动性人格与求职行为之间起部分中介作用;就业情境压力正向调节主动性人格与求职行为之间的关系,即感知的就业情境压力越大,主动性人格与求职行为之间的正向关系越强。     

提纲策略对写作成绩影响的实验研究

本研究通过两个实验,考察了写作构思阶段的自我调控策略之一的提纲之运用对写作成绩的影响及其机制。实验一发现,书面提纲和心理提纲这两种常见的提纲形式对不同长度文章的写作质量有同等的积极影响;实验二发现,“半书面提纲”形式对写作质量的影响要显著好于书面提纲。研究表明,提纲策略效应的发挥,主要在于它帮助作者提高了构思阶段的认知加工水平。     

Culture and perceptions of self—other similarity

In testing possible cultural effects of the use of the self as an habitual reference point to which others are compared, we expected that: (a) individualistic participants (i.e., those who give priority to personal goals) would rate self—other similarity higher when asked “How similar is X to you?” than when asked “How similar are you to X?”, whereas nondirectional similarity judgements (“How similar are these two people?”) would resemble the former directional comparison; (b) collectivistic participants (i.e., those who give priority to in‐group goals) would show a weaker or, possibly, reversed pattern, especially using in‐group comparison others. Neither hypothesis was upheld. However, the individualists perceived the in‐group to be relatively more similar to themselves as compared to the collectivists. This difference cannot be explained by response bias, status asymmetry, or role differentiation. We propose an explanation in terms of the differential relationship between self and other representations for people from collectivist versus individualist cultures.

Effects of shape parameters on the attractiveness of a female body

Various researchers have suggested that certain anthropometric ratios can be used to measure female body attractiveness, including the waist to hip ratio, Body Mass Index (BMI), and the body volume divided by the square of the height (Volume-Height Index). Based on a wide range of female subjects and virtual images of bodies with different ratios, Volume-Height Index was found to provide the best fit with female body attractiveness, and the effect of Volume-Height Index can be fitted with two half bell-shaped exponential curves with an optimal Volume-Height Index at 14.2 liter/m2. It is suggested that the general trend of the effect of Volume-Height Index may be culturally invariant, but the optimal value of Volume-Height Index may vary from culture to culture. In addition to Volume-Height Index, other body parameters or ratios which reflect body proportions and the traits of feminine characteristics had smaller but significant effects on female body attractiveness, and such effects were stronger at optimum Volume-Height Index.     

多题多做测验模型及其应用

在IRT框架下,建立了0-1评分方式下单维双参数Logistic多题多做（MAMI）测验模型。与Spray给出的一题多做（MASI）模型相比,MAMI不仅模型更加精致,而且扩展了适用范围,参数估计方法也不同,采用EM算法求取项目参数。Monte Carlo模拟结果显示,应用MAMI测验模型与测验题量作相应增加的作法相比,两者给出的能力估计精度相同,但MAMI模型给出的项目参数估计精度更高。如果将MAMI测验模型与被试人数相应增加的作法相比,项目参数的估计精度相同,但MAMI给出的能力参数估计精度更高。这个发现表明,在一定条件下若允许修改答案,并采用累加式记分方式,纵使题量不变,也可使能力估计的精度相当于题量增加一倍的估计精度,而项目参数估计精度也会提高。这些发现不仅对技能评价和认知能力评价有参考价值,而且对数据的处理方式也有参考价值
