The Sufficient and Necessary Condition for the Identifiability and Estimability of the DINA Model

Psychometrika - Cognitive diagnosis models (CDMs) are useful statistical tools in cognitive diagnosis assessment. However, as many other latent variable models, the CDMs often suffer from the...     

Implicit theories of shyness in American and Chinese children

This study examined whether implicit theories of shyness differed between American and Chinese children and how this difference helped explain cultural variations in stereotypical views about shy children and relationship with shy peers. We found that regardless of cultural group, children's implicit theories of shyness were not related to their own shyness, but were associated with stereotypical views about shy children (positively) and relationship with shy peers (negatively). American children reported stronger entity theories of shyness, i.e., they were more likely to view shyness as a stable and immutable trait than Chinese children, which partly explained why they had worse relationships with shy peers. These findings highlight the important roles implicit theories may play in understanding cultural similarities and differences in interpersonal perception and relationship.     

金钱激励在社会排斥影响不确定性决策中的调节作用

研究从金钱补偿的视角考察社会排斥对不确定性决策的影响以及金钱激励的调节作用。实验发现,有金钱激励时,被排斥者在爱荷华赌博任务(Iowa gambling task,IGT)中的行为分数(组块2和3的选牌净分数和总的盈利分数)显著高于社会接纳者,表现为风险规避; 在无金钱激励时,被排斥者在IGT任务中的行为分数(组块4和5的选牌净分数和总的盈利分数)显著低于被接纳者,表现为风险寻求。实验结果表明社会排斥对不确定性决策的影响受到金钱激励的调制。     

中国人敬畏特质的心理结构研究

本研究基于人格词汇学假设,探索中国人敬畏特质的心理结构。通过文献分析、专家访谈、开放式和半开放式问卷调查,建立39个词汇的敬畏特质词汇表。在此基础上,进行项目分析、探索性因素分析、验证性因素分析和信效度检验,编制了包含24个词汇的中国人敬畏特质词汇评定问卷。结果表明:(1)中国人的敬畏特质是一个包括谨慎、尊重、谦卑、欣赏的四维结构;(2)编制的中国人敬畏特质词汇评定问卷的信效度符合心理测量学的要求。     

社会认知双加工视角下的刻板印象激活机制

刻板印象激活过程中意识干预与否的问题,催生了内隐与外显两种激活理论长久以来的争端。其根源在于现有研究的刻板激活操作不严谨、两类范式不可比等多个方面。社会认识双加工理论提供了独特的分阶段比较视角。在该理论视角下,文章从梳理内隐及外显理论争端入手,分析各自存在的问题,并以双加工理论为指导,设计了一项内隐及外显任务分离启动研究,以期为探明刻板印象的认知激活机制,提供方法上的支撑。     

Associations of depression,anxiety and PTSD with neurological disability and cognitive impairment in survivors of moyamoya disease

Depression, anxiety and posttraumatic stress disorder (PTSD) are common complications of cerebrovascular diseases. However, they were seldom explored in Moyamoya Disease (MMD) survivors. In this study, we measured the prevalence of depression, anxiety and PTSD in MMD survivors. We evaluated the association of mental disorders with neurological disability and cognitive impairment, and further find out the independent protective and risk factors of neurological disability and cognitive impairment. In MMD survivors, the prevalence of these three mental disorders is high, 46.7% for depression, 50% for anxiety and 47.5% for PTSD. Anxiety and PTSD were significantly associated with more severe neurological disability (p = 0.039 and < 0.001); depression and anxiety were significantly associated with greater cognitive deficiency (p = 0.004 and 0.002). We further found PTSD was the only risk factor associated with neurological disability, and the corresponding odds ratio (OR) and 95% confidence interval (CI) was 81.74 (9.91–674.17); depression and anxiety were risk factors associated with cognitive impairment, and the corresponding OR and 95%CI were 2.73 (1.10–6.81) and 3.37 (1.29–8.78). Therefore, these three mental disorders were associated with more severe neurological disability and greater cognitive deficiency in MMD survivors.     

State mindfulness,rumination, and emotions in daily life: An ambulatory assessment study

While the majority of studies have focused on dispositional mindfulness and the efficacy of mindfulness meditation, there has been limited study exploring the effect of state mindfulness on emotions and its potential mechanism. Therefore, we conducted an ambulatory assessment study to monitor state mindfulness and emotions in daily life and examine the mediating effect of rumination in a natural context. One hundred Chinese university students rated their state mindfulness, rumination, and emotions (e.g., anxiety, depression, happiness) five times per day for a week. Using hierarchical linear models, we and found that at the within‐person level, higher current state mindfulness was associated with more subsequent positive emotions and less subsequent negative emotions. Current rumination partially mediated the relation between current state mindfulness and subsequent positive emotions (happiness, relaxation, contentment, interest) and negative emotions (depression, anger, boredom, sadness). At the between‐person level, higher state mindfulness was associated with more positive emotions and less negative emotions. Individuals’ overall rumination partially mediated the relation between state mindfulness and emotions (depression, anger, boredom, sadness, relaxation). We concluded that higher state mindfulness was associated with lower rumination, which in turn resulted in more positive emotions and less negative emotions. More important, state mindfulness also exerted a dynamic impact on daily emotions via rumination.     

非安全依恋可塑性的神经机制

非安全依恋可塑性是借助认知启动技术(例如安全依恋启动)使非安全依恋个体长期处于敏感和支持性的环境中, 从而唤醒个体积极的依恋经历, 使其对依恋关系形成新的认知图式, 最终实现非安全依恋个体内部工作模型的重构。本项目针对非安全依恋个体的认知加工缺陷, 采用安全依恋启动的方法探索非安全依恋可塑性的发生机制及相应的神经生理基础。项目拟从单次安全依恋启动对非安全依恋个体认知加工缺陷的改善效应、多任务条件下对重复安全启动效应的检验以及重复安全依恋启动效应的追踪研究三方面开展非安全依恋可塑性研究; 研究手段采用行为-生理-脑成像的技术, 从安全依恋启动的性质、方式和时间三个维度上系统地探究非安全依恋可塑性的发生机制与神经基础。非安全依恋可塑性研究为安全依恋研究提供了新视角, 研究提出的依恋图式重构理论是对安全基地图式理论的印证与发展, 对重复安全启动效应的检验及追踪研究试图为非安全依恋可塑性研究构建一套科学有效的评估标准。研究成果对于非安全依恋人群的干预训练、提升依恋安全感、维护心理健康具有重要价值。
