自恋人格调节信任博弈的结果评价

自恋人格个体表现出亲社会行为的减少和对他人的反馈敏感。信任是人类社会互动行为的基础,自恋人格特质可能影响他们的信任决策。为了探究自恋水平如何影响信任博弈中结果评价的大脑活动,本研究采用事件相关电位技术记录了38名被试完成单次信任博弈时的脑电波。行为结果发现相对高自恋者的信任选择率显著低于相对低自恋者的信任选择率。脑电结果表明,相对高自恋者信任损失反馈减互惠获利反馈所得的FRN差异波(d FRN)显著地大于相对低自恋者,并且相对高自恋者结果评价诱发的P300波幅显著地大于相对低自恋者。本研究提供了自恋人格个体信任博弈中结果评价的初步神经电生理学证据。     

初中生公正世界信念对其学业成就的影响:感知的教师支持和班级公正的中介作用

公正世界信念作为一种社会认知倾向,对于个体发展具有普遍影响,但是在学校情境中探索公正世界信念与学业成就的关系及影响机制的研究却很有限。本研究以郑州市两个区县的2584名初中一年级学生为被试,考察公正世界信念对其学业成就的影响,从班级生态环境的角度,探索个体对教师支持和班级公正的感知在二者之间的中介作用。结果发现：初中生的公正世界信念可显著预测其学业成就;在控制了性别、年龄后,学生的公正世界信念可分别通过对教师支持和班级公正的感知间接影响其学业成就,公正世界信念还可以通过感知的教师支持影响对班级公正的感知,进而影响学业成就的多重中介路径发挥作用。个体对班级教师支持和班级公正的感知是公正世界信念影响学业成就的重要途径。     

亲子依恋与农村留守青少年焦虑的关系:教师支持的保护作用

本研究以306名父外留守、147名双留守和288名非留守青少年为被试,以亲子依恋问卷、领悟社会支持量表和儿童焦虑量表为研究工具,考察了亲子依恋与留守青少年焦虑的关系以及教师支持的保护作用。结果发现：（1）双留守青少年的母子依恋、父子依恋安全性显著低于,焦虑水平显著高于父外留守和非留守青少年,后两组青少年之间差异不显著;（2）安全性母子依恋能降低父外留守青少年的焦虑水平,安全性父子依恋能降低非留守和双留守青少年的焦虑水平;（3）安全性母子依恋能补偿不安全父子依恋对父外留守青少年焦虑的影响;（4）教师支持既能降低非留守和双留守青少年的焦虑水平,也能增强安全性父子依恋对父外留守青少年焦虑的保护作用。     

婴儿指示性手势与其语言学习的关系

指示性手势是指明空间中某个物体、处所或事件的手部动作,在婴儿1岁时出现,与婴儿的语言学习存在着较强的相关,然而目前尚不清楚为什么会存在此相关。可能存在两种内在机制:(1)指示性手势影响婴儿的学习环境——引发了适时的语言输入;(2)影响学习者本身——帮助婴儿创造有效的学习状态并示意给他人。未来的研究需要探讨这两种机制如何交互作用,以及如何将指示性手势作为诊断或干预工具,用于识别和帮助有语言障碍风险的个体。     

吸烟:促进还是损害前瞻记忆?

以往研究对吸烟或尼古丁摄入影响前瞻记忆的特点和机制进行了探讨,发现吸烟或尼古丁摄入对前瞻记忆的影响具有双重机制:尼古丁能短暂刺激神经递质释放,并通过促进策略加工提高即时的前瞻记忆表现;但长期来看,吸烟会损伤心脑血管和神经元,降低认知和执行功能的水平,从而持久损害前瞻记忆。将来的研究应在区分前瞻记忆任务类型、尼古丁摄入方式等的基础上,进一步明确吸烟或尼古丁摄入影响前瞻记忆的机制。     

How does exposure to masked individuals affect White Americans' attitudes toward Asian American and Pacific Islanders?

Across three studies, conducted between Spring 2020 and Spring 2021, we tested whether exposure to an Asian American/Pacific Islander (AAPI) target person wearing a face mask would increase or decrease White Americans' perceived threat from and positivity toward AAPI individuals. Although results varied by study, a single-paper meta-analysis revealed that the masked (compared to unmasked) AAPI target resulted in greater positivity toward AAPIs, due to reduced perceptions of both symbolic threat to group values and realistic threat to group health. Positivity toward AAPIs did not reliably differ after exposure to a masked versus unmasked White target. Implications for interventions that encourage COVID-safe behaviors and combat anti-AAPI attitudes are discussed.     

Friend support of dating relationships: Comparing relationship type,friend and partner perspectives

This study assessed the role of friends in dating relationships, comparing on–off and noncyclical relationships. Participants (N = 460) reported on the friend most familiar with their current or recent dating relationship. We examined friend support of and influence on the dating relationship and the influence of the dating relationship on the friendship. Participants' friends (N = 98) completed a similar survey to compare participants' and friends' perceptions. On–off partners reported less support for the dating relationship than did noncyclical partners. On–off partners also reported greater openness, whereas friends reported greater frequency, of communicating about the dating relationship. Friends also felt the relationship changed the friendship more; friends of on–off partners in particular reported more positive change to their friendship.     

Specifying Ability Growth Models Using a Multidimensional Item Response Model for Repeated Measures Categorical Ordinal Item Response Data

When categorical ordinal item response data are collected over multiple timepoints from a repeated measures design, an item response theory (IRT) modeling approach whose unit of analysis is an item response is suitable. This study proposes a few longitudinal IRT models and illustrates how a popular compensatory multidimensional IRT model can be utilized to formulate such longitudinal IRT models, which permits an investigation of ability growth at both individual and population levels. The equivalence of an existing multidimensional IRT model and those longitudinal IRT models is also elaborated so that one can make use of an existing multidimensional IRT model to implement the longitudinal IRT models.     

Limited‐information goodness‐of‐fit testing of diagnostic classification item response models

Despite the growing popularity of diagnostic classification models (e.g., Rupp et al., 2010, Diagnostic measurement: theory, methods, and applications, Guilford Press, New York, NY) in educational and psychological measurement, methods for testing their absolute goodness of fit to real data remain relatively underdeveloped. For tests of reasonable length and for realistic sample size, full‐information test statistics such as Pearson's X² and the likelihood ratio statistic G² suffer from sparseness in the underlying contingency table from which they are computed. Recently, limited‐information fit statistics such as Maydeu‐Olivares and Joe's (2006, Psychometrika, 71, 713) M₂ have been found to be quite useful in testing the overall goodness of fit of item response theory models. In this study, we applied Maydeu‐Olivares and Joe's (2006, Psychometrika, 71, 713) M₂ statistic to diagnostic classification models. Through a series of simulation studies, we found that M₂ is well calibrated across a wide range of diagnostic model structures and was sensitive to certain misspecifications of the item model (e.g., fitting disjunctive models to data generated according to a conjunctive model), errors in the Q‐matrix (adding or omitting paths, omitting a latent variable), and violations of local item independence due to unmodelled testlet effects. On the other hand, M₂ was largely insensitive to misspecifications in the distribution of higher‐order latent dimensions and to the specification of an extraneous attribute. To complement the analyses of the overall model goodness of fit using M₂, we investigated the utility of the Chen and Thissen (1997, J. Educ. Behav. Stat., 22, 265) local dependence statistic $X_{\mathrm{LD}}^2$ for characterizing sources of misfit, an important aspect of model appraisal often overlooked in favour of overall statements. The $X_{\mathrm{LD}}^2$ statistic was found to be slightly conservative (with Type I error rates consistently below the nominal level) but still useful in pinpointing the sources of misfit. Patterns of local dependence arising due to specific model misspecifications are illustrated. Finally, we used the M₂ and $X_{\mathrm{LD}}^2$ statistics to evaluate a diagnostic model fit to data from the Trends in Mathematics and Science Study, drawing upon analyses previously conducted by Lee et al., (2011, IJT, 11, 144).
