Well‐being and the accessibility of pleasant and unpleasant concepts

The trait–congruency hypothesis predicts that persons high in positive or negative trait affect more readily process pleasant or unpleasant stimuli, respectively. In two studies, participants were administered measures of personality and affect. Moreover, a yes/no lexical decision task with pleasant, unpleasant and neutral words was administered in Study 1, whereas a go/no‐go task was used in Study 2. Several methods to increase reliabilities of differences in reaction times are explored. Correlations of measures of personality and trait affect with decision times were mostly consistent with the trait–congruency hypothesis, particularly for decision times in the go/no‐go task that measured individual differences in valence‐specific decision times more reliably. The findings suggest that trait‐related concept accessibility is one source of trait congruity. Copyright © 2006 John Wiley & Sons, Ltd.     

透析GT信度观及其存在的问题

概化理论(GT)与经典测验理论(CTT)是随机测量模型下信度评量的重要理论来源。本文将重复测量作为理解概化理论产生与建构的切入点,剖析了GT在测验假设、全域分思想与误差观三方面的特点,提出了目前GT在理论与应用方面存在的若干问题与不足。     

Motor-Skill Learning in Alzheimer’s Disease: A Review with an Eye to the Clinical Practice

Since elderly people suffering from dementia want to go on living independently for as long as possible, they need to be able to maintain familiar and learn new practical skills. Although explicit or declarative learning methods are mostly used to train new skills, it is hypothesized that implicit or procedural techniques may be more effective in this population. The present review discusses 23 experimental studies on implicit motor-skill learning in patients with Alzheimer’s disease (AD). All studies found intact implicit motor-learning capacities. Subsequently, it is elaborated how these intact learning abilities can be exploited in the patients’ rehabilitation with respect to the variables ‘practice’ and ‘feedback.’ Recommendations for future research are provided, and it is concluded that if training programs are adjusted to specific needs and abilities, older people with AD are well able to (re)learn practical motor skills, which may enhance their autonomy.     

西方诚信度测验研究述评

诚信度测验是指在招聘和选拔过程中用于评价应聘者的诚实、诚信、可依靠性,从而预测他们的偷盗、违反纪律、反工作行为以及今后工作业绩的以纸笔测验为主的测验工具。文章对西方诚信度测验的发展和应用现状做出了综述,指出诚信度测验具有较好的信度和效度。大五人格模型中的责任感、宜人性和情绪稳定性是诚信度测验潜在的测量内容,但诚信度测验与大五人格模型以外的其它人格维度也存在较高的相关性。诚信度测验对反工作行为和整体工作绩效具有良好的预测效度。文章在总结诚信度测验存在的一些争议和问题的基础上,提出了它在中国企业员工招聘和选拔中应用的若干建议     

成人依恋的测量：亲密关系经历量表（ECR）中文版

为了促进在中国开展有关成人依恋的研究,对目前国外该领域中广泛采用的“标准”成人依恋量表——“亲密关系经历量表（ECR）”——进行了中文版修订。371名中国大学生接受了测试,并用自尊量表,他人观量表等作为检验效度的依据。其中59人在四周后进行了重测。对其中的231名正处于恋爱中的被试的结果进行了统计分析,包括采用项目反应理论进行项目分析、信效度检验。结果表明,该量表的中文版具有较好的信度（内部一致性、和重测信度）以及效度（构想效度和效标效度）     

用Delta法估计多维测验合成信度的置信区间

大量研究表明,一般情况下用合成信度可以较好地估计测验信度。对于合成信度及其置信区间的估计方法,在单维测验的情形已有不少研究。但罕有研究讨论多维测验合成信度的区间估计方法。本文用Delta法推导出计算多维测验合成信度的标准误公式,进而计算置信区间,并用一个例子说明如何编程估计多维测验合成信度及其置信区间。     

新HSK书写成绩可靠性影响因素的概化理论分析

本研究以概化理论为视角,搜集了新HSK五级模拟书写题的作答和评分数据,估算了题型、题量、评卷员人数、评阅速度等潜在影响效应的方差分量,考察了新HSK书写成绩的可靠性,并探索了改善该分数可靠性的途径。基于概化理论和规划求解的数据分析发现了题量的调整方案以及题型、题量、评卷员人数的最优组合方案。本研究对评阅速度进行的分析属于前沿性的理论探索,而其他数据分析结果,则可能有益于旨在改进该测试质量的决策实践。     

On the distribution of the maximum likelihood estimator of Cronbach's alpha

The asymptotic normal distribution of the maximum likelihood estimator of Cronbach's alpha (under normality) is derived for the case when no assumptions are made about the covariances among items. The asymptotic distribution is also considered for the special case of compound symmetry and compared to the exact distribution.The authors would like to thank Willem J. Heiser, an associate editor and the reviewers for valuable and helpful comments to improve the quality of this work.     

Differential Conditioning Based on a Difference in the Predictability of Reinforcement

A Pavlovian procedure containing a set of several alternative reliable trial stimuli and a set of several alternative unreliable trial stimuli was used to determine if reliability of outcome, per se, would differentially condition additional trial stimuli that either preceded or followed those original trial stimuli in a serial conditioning paradigm. The reinforcing effectiveness of the antecedent stimuli themselves was later tested in a higher-order conditioning design. It was found that different rates could be established to the different antecedent stimuli in the absence of a difference in the probability of reinforcement. Further, stimuli paired with those antecedent stimuli in the higher-order conditioning test also exhibited a difference in rate. It was concluded that a combination of a stimulus that is always followed by food and another that is never followed by food are, in net, a more effective reinforcer than a common stimulus that has the same overall probability of reinforcement but which is followed by both outcomes.     

多层次研究的数据聚合适当性检验:文献评价与关键问题试解

组织管理领域的多层次研究经常需要测量共享单位特性构念, 常用方法是将单位内若干个体成员的评分聚合到单位层次, 确保聚合后的分数具有充分代表性的统计前提是通过聚合适当性检验。聚合适当性检验的常用指标是组内一致性r_WG和组内信度ICC(1)、ICC(2), 但目前学界对于这两类指标何者更优、r_WG的原分布选择和数据清理、各指标的划界值等关键问题存在诸多争议。为此, 首先对国内9份管理学、心理学期刊2014年以来发表的166篇包含聚合适当性检验的论文进行内容分析, 并以Journal of Applied Psychology上的85篇论文为对比, 查明常规实践中的共性问题, 进而提出实践建议:(1)明确功能定位, 将r_WG作为聚合适当性指标, ICC(1)和ICC(2)分别作为效度、信度指标。(2)计算r_WG时审慎选择原分布, 排除组内一致性过低的组。(3)为各指标设定更加合理、有适度灵活性的划界值, 停止使用武断、粗糙的经验标准。最后, 强调研究者在模型构建和聚合决策中应加强理论考量, 避免片面依赖统计检验结果。
