社会困境下政治信任对公众态度和合作行为的影响

现代社会面临的重要问题是如何有效地促进人们之间的相互合作,达到社会公共利益的最大化。因此,有关社会困境(social dilemma)的研究成为社会心理学领域的热点。随着群体理论的发展,研究者的研究视角逐渐从个体(individual)转向群体(collective),关注层级结构的群体(hierarchical groups)中,管理者或管理机构(权威)的特征和行为对个体合作行为的影响。其中,权威信任(trust in authority)和公正感(fairness)是影响个体态度和合作行为的重要变量。政治信任(political trust)也可以看作权威信任的一种,即在社会背景下,公众对社会管理权威(政府机构)的信任。未来研究应尝试在实验室里对政治信任的作用和机制进行探究,并进一步探究公正感在政治信任对态度及合作行为关系中的中介作用。

体重污名:对肥胖的歧视与偏见

体重污名指个体因超重或肥胖受到的社会污名,主要表现为公众对这一群体的歧视、偏见、消极态度,其测量主要从公众和被污名群体自身展开。它会对被污名个体的心理、行为、身体产生消极影响,且这些影响之间存在递进关系。现有体重污名干预研究主要聚焦于减少公众污名、降低体重以及缓解体重污名消极心理影响三个方向。未来研究可以在体重污名影响机制、测量工具和行之有效的干预策略方面进一步扩展。     

政策执行偏差严重程度对公众地方政府责任判断的影响机制

为探讨地方政府政策执行偏差严重程度对公众地方政府责任判断的影响机制。采用问卷法对728名社会公众进行调查,结果显示：（1）公众地方政府有意性判断和公众地方政府可控归因中介了政策执行偏差严重程度与公众地方政府责任判断之间的关系。（2）政策执行偏差严重程度还通过公众地方政府有意性判断→公众地方政府可控归因的中介链作用于公众地方政府道德责任判断。并对研究的实践启示进行了讨论。     

员工建言行为的结果及其调节机制

该文从个体层面和群体层面对员工建言行为结果的研究进行综述。个体层面建言结果大致可以分为五个方面：员工绩效、工作态度、人际关系、建言采纳和后续建言行为; 群体层面的结果主要包括群体绩效、群体创新和群体离职。无论是在个体层面还是在群体层面, 建言对其结果的影响研究结论都不尽一致。个体层面研究结论的不一致可能是受建言特点(类型和策略)、建言者身份、建言对象反应、建言情境等调节因素的影响; 群体层面结论的不一致可能归因于建言对象和管理者可用资源等的调节作用。未来研究应进一步探索管理者对建言不同类型反应的原因, 探究群体建言的作用机制。     

企业管理者沟通能力对组织群体凝聚力影响的实证研究

企业管理者沟通能力是影响企业管理绩效的重要因素。本研究运用自编“管理者沟通能力问卷”、“员工群体凝聚力问卷”,对北京、上海、沈阳、宁夏和广州等城市的429名企业管理者和员工进行测量,采用SPSS11.0社会统计分析软件包进行沟通能力与群体凝聚力的多元逐步回归分析。结果表明,沟通能力对于群体凝聚力具有较高预测性,其中人际沟通能力对群体凝聚力的解释能力较强,从而证实群体凝聚力是可以作为检验沟通能力的重要效标的;言语表达能力在对群体凝聚力的回归方程中占据最大成分。

测验同质性系数及其区间估计

在决定将多维测验分数合并成测验总分时, 应当考虑测验同质性。如果同质性太低, 合成总分没有什么意义。同质性高低可以用同质性系数来衡量。用来计算同质性系数的模型是近年来受到关注的双因子模型(既有全局因子又有局部因子), 测验的同质性系数定义为测验分数方差中全局因子分数方差所占的比例。本文用Delta法推导出计算同质性系数的标准误公式, 进而计算其置信区间。提供了简单的计算同质性系数及其置信区间的程序。用一个例子说明如何估计同质性系数及其置信区间, 通过模拟比较了用Delta法和用Bootstrap法计算的置信区间, 发现两者差异很小。

Joint Procrustes Analysis for Simultaneous Nonsingular Transformation of Component Score and Loading Matrices

In component analysis solutions, post-multiplying a component score matrix by a nonsingular matrix can be compensated by applying its inverse to the corresponding loading matrix. To eliminate this indeterminacy on nonsingular transformation, we propose Joint Procrustes Analysis (JPA) in which component score and loading matrices are simultaneously transformed so that the former matrix matches a target score matrix and the latter matches a target loading matrix. The loss function of JPA is a function of the nonsingular transformation matrix and its inverse, and is difficult to minimize straightforwardly. To deal with this difficulty, we reparameterize those matrices by their singular value decomposition, which reduces the minimization to alternately solving quartic equations and performing the existing multivariate procedures. This algorithm is assessed in a simulation study. We further extend JPA for cases where targets are linear functions of unknown parameters. We also discuss how the application of JPA can be extended in different fields.     

基于等级反应模型的属性层级方法

给出基于等级反应模型的属性层级方法（Attribute Hierarchy Method, AHM）,并简记为GRM-AHM,提出了相应的确定GRM-AHM的期望项目反应模式全集的方法和一种新的归类法LL。用蒙特卡洛模拟实验比较GRM-AHM的几种归类法的归准率（属性模式归准率和单个属性的平均判准率）。结果发现,新归类法的归准率与AHM中的方法A差不多,但比方法B高很多;随着被试作答失误率的提高,它们的归准率都有所下降。在归类精度和简单性方面,GRM-AHM都比Bolt等(2004)提出的多级评分融合模型（Fusion Model）好

A blueprint of ELI: A new method for eliciting subjective probability distributions

A blueprint of a new method for eliciting uncertain knowledge about continuous quantities is presented. The direct realization of a proper scoring rule in a graphically oriented interactive computer program is one of the central features of the new elicitation methodology. Uncertain knowledge is internally represented through subjective probability distributions. However, in its interaction with assessors, the elicitation method uses a score representation. A proper scoring rule is applied to transform probability density functions into score functions. In order to study its merits, central ideas for the new method were implemented in an experimental version of the elicitation technique ELI. The results were promising and encouraged further development of the technique.     

Asymptotic Standard Errors of Generalized Partial Credit Model True Score Equating Using Characteristic Curve Methods

In this study, the delta method was applied to estimate the standard errors of the true score equating when using the characteristic curve methods with the generalized partial credit model in test equating under the context of the common-item nonequivalent groups equating design. Simulation studies were further conducted to compare the performance of the delta method with that of the bootstrap method and the multiple imputation method. The results indicated that the standard errors produced by the delta method were very close to the criterion empirical standard errors as well as those yielded by the bootstrap method and the multiple imputation method under all the manipulated conditions.     

Decomposition of a Rasch partial credit item into independent binary and indecomposable trinary items

For each Rasch (Masters) partial credit item, there exists a set of independent Rasch binary and indecomposable trinary items for which the sum of the scores and the partial credit score have identical probability density functions. If each indecomposable trinary item is further expressed as the sum of two binary items, then the binary items are positively dependent and cannot be both of the Rasch type. This paper was written while the author was working with Steve Ferrara and Hillary Michaels on some technical aspects of the Maryland School Performance Assessment Program. The author had been puzzled by the fact that most MSPAP assessment items have three or less score categories. With a psychometric justification now being apparent, this paper is dedicated to both of them.     

Dynamic testing of learning potential in adults with cognitive impairments: A systematic review of methodology and predictive value

Dynamic testing includes procedures that examine the effects of brief training on test performance where pre‐ to post‐training change reflects patients’ learning potential. The objective of this systematic review was to provide clinicians and researchers insight into the concept and methodology of dynamic testing and to explore its predictive validity in adult patients with cognitive impairments. The following electronic databases were searched: PubMed, PsychINFO, and Embase/Medline. Of 1141 potentially relevant articles, 24 studies met the inclusion criteria. The mean methodological quality score was 4.6 of 8. Eleven different dynamic tests were used. The majority of studies used dynamic versions of the Wisconsin Card Sorting Test. The training mostly consisted of a combination of performance feedback, reinforcement, expanded instruction, or strategy training. Learning potential was quantified using numerical (post‐test score, difference score, gain score, regression residuals) and categorical (groups) indices. In five of six longitudinal studies, learning potential significantly predicted rehabilitation outcome. Three of four studies supported the added value of dynamic testing over conventional testing in predicting rehabilitation outcome. This review provides preliminary support that dynamic tests can provide a valuable addition to conventional tests to assess patients’ abilities. Although promising, there was a large variability in methods used for dynamic testing and, therefore, it remains unclear which dynamic testing methods are most appropriate for patients with cognitive impairments. More research is warranted to further evaluate and refine dynamic testing methodology and to further elucidate its predictive validity concerning rehabilitation outcomes relative to other cognitive and functional status indices.     

The measurement of creativity by the Stroop Color and Word Test.

The development of a valid and reliable measure of creativity has been a challenging problem to psychologists. Gamble and Kellner (1968) have suggested that the Stroop Color and Word Test (SCWT) might be such a measure. The advantages of the Stroop include that it tests basic processes, is stable over long periods of time, and is easy to administer and score. The present study investigated the relationship of the Stroop to three independent measures of creativity: a verbal task, a nonverbal task, and ratings by teachers. In all cases a significant relationship was found between these measures and the Stroop interference score. A concept of creativity as a basic underlying process is discussed by the author as well as implications for further research.
