A Comparison of Multilevel Mediation Modeling Methods: Recommendations for Applied Researchers

Multilevel structural equation modeling (MSEM) has been proposed as a valuable tool for estimating mediation in multilevel data and has known advantages over traditional multilevel modeling, including conflated and unconflated techniques (CMM & UMM). Recent methodological research has focused on comparing the three methods for 2-1-1 designs, but in regards to 1-1-1 mediation designs, there are significant gaps in the published literature that prevent applied researchers from making educated decisions regarding which model to employ in their own specific research design. A Monte Carlo study was performed to compare MSEM, UMM, and CMM on relative bias, confidence interval coverage, Type I Error, and power in a 1-1-1 model with random slopes under varying data conditions. Recommendations for applied researchers are discussed and an empirical example provides context for the three methods.     

Gray Matter Atrophy in the Cortico-Striatal-Thalamic Network and Sensorimotor Network in Relapsing–Remitting and Primary Progressive Multiple Sclerosis

Neuropsychology Review - Gray matter atrophy in multiple sclerosis (MS) is thought to be associated with disability and cognitive impairment, but previous studies have sometimes had discordant...

幼儿教师情绪劳动策略与职业倦怠的关系:基于潜在剖面分析

基于个体中心的视角考察幼儿教师情绪劳动策略和职业倦怠的关系,采用幼儿教师情绪劳动策略量表和职业倦怠量表对495名幼儿教师进行问卷调查。运用潜在剖面分析方法进行数据分析,结果表明：（1）幼儿教师情绪劳动策略可以分为四种潜在类别：积极型、内热型、珍爱型和冷淡型,其中积极型人数最多,冷淡型人数最少;（2）幼儿教师的职业倦怠得分在这四种潜在类别上有显著差异,冷淡型的职业倦怠得分最高,积极型次之,内热型和珍爱型的职业倦怠得分最低且无显著差异。研究结果为幼儿教师情绪劳动与职业倦怠的关系探讨提供了新的视角。     

对一名受虐男孩的箱庭治疗

本研究采用个案研究法,对一名13岁受虐男孩（小N）实施了25次的箱庭治疗,研究了该儿童箱庭治疗过程的特点及箱庭疗法的治疗效果。结果发现：个案的箱庭治疗经历了问题呈现、自我调适、对抗斗争和问题解决四个阶段;箱庭治疗过程中,个案所使用的玩具数量及种类从贫乏单一转向丰富多样;经过箱庭治疗,个案的抑郁、焦虑情绪得以较大缓解,自我意识得到提高,同伴关系显著改善,学业成绩也得到较大提高。     

不同认知方式对词—面孔任务Stroop效应的影响

该研究采用词—面孔Stroop任务,以76名大学生为被试,探讨了不同认知方式（场独立、场依存）对情绪冲突Stroop效应的影响。结果发现：（1）情绪冲突的Stroop效应显著,即,在词—面孔Stroop任务中,当词和面孔的情绪效价一致时,被试的反应时更短,正确率更高。（2）认知方式对情绪冲突Stroop任务的影响显著,表现为无论是一致还是不一致条件下,场独立者比场依存者的反应时都更短。（3）场依存者的情绪冲突Stroop效应更大,表现为其在词—面孔情绪效价一致和不一致条件下的反应时差异更大。     

The Development of Self-Esteem and the Role of Agency and Communion: A Longitudinal Study among Chinese

There is a long and rich history of research on self-esteem in children. However, little is known about developmental changes in self-esteem and the association between self-esteem and two basic dimensions of social cognition. This study aims to examine the developmental trajectory of self-esteem and its relationships with two basic dimensions of social cognition: agency and communion among 276 Chinese elementary school students by a two-wave 1-year longitudinal study. Agentic characteristics aid in achieving goals, while communion refers to qualities that aid in social relationships. Both play a part in children’s developing self-esteem to varying degrees. The changes in self-esteem on mean-level and individual-level and the rank-order stability of self-esteem were assessed and the results showed that the development of self-esteem was relatively stable but with some fluctuations during childhood, and no gender difference was found in its development in a Chinese setting. Hierarchical regression was used to test the association of agency and communion with self-esteem and the findings showed that children’s self-esteem was dominated by agency over communion in general; however, when grade was taken into consideration, the predictive effect of agency and communion on children’s self-esteem changed from communion to agency from younger to older children, respectively.     

发展性阅读障碍儿童阅读中的眼跳定位缺陷：基于新词学习的实验证据

通过与生理年龄匹配儿童比较新词重复学习中眼跳定位模式变化的异同, 探讨发展性阅读障碍儿童在新词学习中的眼跳定位是否存在缺陷。以发展性阅读障碍儿童和生理年龄匹配儿童为被试, 采用重复学习新词范式, 结果发现：(1)与生理年龄匹配组相比, 发展性阅读障碍儿童跳入新词的眼跳距离较短、首次注视落点位置更靠近词首; (2)生理年龄匹配组儿童利用学习次数调节新词眼跳定位模式的能力高于发展性阅读障碍儿童, 即随着新词学习次数的增加, 生理年龄匹配组儿童跳入和跳出新词的眼跳距离随之增长, 首次注视落点位置更靠近词中心; 相比之下, 发展性阅读障碍儿童仅在跳出新词的眼跳距离上有所增长, 但增加幅度也显著小于生理年龄匹配组。结果表明, 发展性阅读障碍儿童在新词学习中的眼跳定位, 及利用学习次数对眼跳定位的调节上均表现出一定缺陷。     

个体如何以消费行为应对自我威胁?基于导向-路径整合模型的分析

自我威胁无处不在, 以消费应对自我威胁是个体采取的重要方式。但由于自我概念的多维性、应对威胁过程中认知、情感、情绪等多因素的介入, 以及威胁源和应对行为的交叉性等原因, 当前的研究呈现出结论分散、不连贯, 甚至矛盾的情形。基于导向-路径的整合模型回顾了消费行为领域自我威胁研究的动态, 归纳出个体的多种自我威胁应对策略, 揭示了不同应对策略间的多层次交叉补偿机理, 以及自我威胁与消费行为间的多重关联方式, 并揭示出个体通过产品的全价值系统和自身的全感知系统进行自我威胁应对。基于导向-路径整合模型有助于对消费行为领域自我威胁应对研究形成整体连贯的认知, 揭示其内在规律, 并有助于理解当前环境(新冠肺炎疫情)下的个体消费行为。     

团队多样性与组织支持对团队创造力的影响

采用实验法在专业异质性与群体断层两个水平上操纵团队多样性, 通过两个实验考察团队多样性与组织支持的交互作用对团队创造力的影响。研究结果表明：(1)在独创性维度上, 专业异质团队在工具支持条件下的独创性显著高于专业同质团队, 情感和物质支持条件下二者差异不显著。当团队出现群体断层时, 情感支持与工具支持具有同样的促进作用, 即在这两种组织支持下, 强断层团队的独创性显著高于弱断层团队; 物质支持条件下二者差异不显著。(2)在适宜性维度上, 组织支持的主效应显著, 两个实验一致地发现物质支持条件下的适宜性显著高于情感支持和工具支持。本研究从团队多样性与组织支持交互作用的角度考察不同复杂程度、不同组织目标的多样性团队所需要的组织支持条件, 对促进团队创造力具有一定的理论与实践价值。
