教学设计中的成绩表现和心流体验:基于认知负荷视角

教学设计是为优化教学效果而形成的教学实施方案。为提高学习表现,认知负荷理论认为在组织教学设计时需考虑内、外认知负荷两大因素,但少有研究关注学生在学习过程中的体验。本研究通过单词复合性操纵内在负荷,通过呈现方式操纵外在负荷,探究两类负荷对心流体验及表现的影响。结果发现,内在负荷对心流及表现均有影响,外在负荷仅在低水平组表现出对心流及表现的影响,另外内外负荷在低水平组的表现上存在交互作用。结果表明,教学设计中的内在负荷是影响心流及表现的稳定因素,外在负荷不仅受知识水平影响,其对表现的有效性还受内在负荷的调节。     

汉语儿童语素意识对阅读理解的影响:默读流畅性的中介效应

通过对149名小学一年级学生两年的追踪研究,在控制了一般认知能力、语音意识以及所关注变量自回归效应的情况下,探讨默读流畅性在语素意识与阅读理解关系中的作用。结果发现：（1）儿童语素意识、默读流畅性及阅读理解随时间均有显著发展;（2）一年级下学期儿童的默读流畅性在一年级上学期语素意识影响二年级上学期阅读理解过程中的中介作用显著,而二年级上学期的默读流畅性在一年级下学期语素意识影响二年级下学期阅读理解过程中的中介作用不显著。结果表明,在小学低年级阶段,默读流畅性在早期语素意识与之后的阅读理解中发挥跨时间点的中介作用,且该中介效应随儿童认知技能的发展会发生一定的变化。     

组织中的韧性：基于心理路径和系统路径的保护性资源建构

作为跨学科的研究构念, “韧性” (resilience)呈现出心理和系统两条独立的发展轨迹。基于心理路径和系统路径, 本文系统梳理了韧性在组织不同层面的类型特质、影响因素及测量, 依托资源保护理论, 以保护性资源的建构为主线勾勒出韧性在组织不同层面的产生路径, 并据此提出相关干预策略。未来研究可尝试探究积极事件对韧性的诱发机理以及跨层面韧性之间的促进作用, 并基于心理和系统两条发展脉络开展本土化实证研究。     

Staying friends with ex‐romantic partners: Predictors,reasons, and outcomes

In two studies, we identified predictors of staying friends with an ex‐partner, developed and validated a measure for reasons to stay friends with exes, and examined the outcomes of staying friends. We identified four reasons to stay friends with exes: Security, Practical, Civility, and Unresolved Romantic Desires. Sex, sexual orientation, attachment styles, personality traits, time since breakup, and reasons for breakup all predicted staying friends. Staying friends due to Unresolved Romantic Desires resulted in negative outcomes, whereas staying friends due to Security and Practical reasons resulted in more positive outcomes. Staying friends due to Practical or Civility reasons resulted in the friendship being less likely to last in the long term. Implications for future research and clinical work are discussed.     

Socioeconomic and sociocultural determinants of psychological distress and quality of life among patients with psoriasis in a selected multi-ethnic Malaysian population

Patients with psoriasis may have increased risk of psychological comorbidities. This cross-sectional study aimed at determining associations between sociocultural and socioeconomic factors with the Depression Anxiety Stress Scale (DASS) scores and the Dermatology Life Quality Index (DLQI) scores. Adult patients with psoriasis were recruited from a Dermatology outpatient clinic via convenience sampling. Interviews were conducted regarding socio-demographic factors and willing subjects were requested to complete the DASS and DLQI questionnaires. The Pearson χ² test, Fisher’s exact test and multivariate logistic regression were used for statistical analysis to determine independent predictors of depression, anxiety, stress and severe impairment of quality of life. Unadjusted analysis revealed that depression was associated with Indian ethnicity (p = .041) and severe impairment of quality of life was associated with Indian ethnicity (p = .032), higher education (p = .013), higher income (p = .042), and employment status (p = .014). Multivariate analysis revealed that Indian ethnicity was a predictor of depression (p = .024). For stress, tertiary level of education (p = .020) was an independent risk factor while a higher monthly income was a protective factor (p = .042). The ethnic Indians and Malays were significantly more likely than the ethnic Chinese to suffer reduced quality of life (p = .001 and p = .006 respectively) and subjects with tertiary education were more likely to have severe impairment of quality of life (p = .002). Our study was unique in determining sociocultural influences on psychological complications of psoriasis in a South East Asian population. This has provided invaluable insight into factors predictive of adverse effects of psoriasis on psychological distress and quality of life in our patient population. Future studies should devise interventions to specifically target at risk groups in the development of strategies to reduce morbidity associated with psoriasis.     

急性应激对威胁刺激注意定向和注意解除的影响:认知神经机制研究

急性应激和注意偏向是焦虑障碍和创伤后应激障碍发生和症状保持的两个重要因素。急性应激导致交感神经系统激活以及儿茶酚胺和糖皮质激素分泌增加,因而影响对威胁刺激的注意偏向。但是急性应激如何影响注意偏向中的注意定向和注意解除尚不清楚。本项目采用点探测任务、威胁线索空间提示任务,结合恐惧条件反射、眼动和事件相关电位技术,研究急性应激对注意定向和注意解除影响的认知神经机制。研究结果可为治疗焦虑和创伤后应激障碍提供支持,为公共卫生管理政策的制定提供建议。     

基因与环境的交互作用:来自差别易感性模型的证据

差别易感性模型认为,携带某种基因型的个体既容易受到消极环境的不利影响,同时也容易受到积极的、支持性环境的有利影响。随着定量遗传学和分子遗传学技术的不断发展,涌现出关于基因-环境对儿童发展交互作用的大量研究,主要包括5-HTTLPR、DRD4、MAOA、COMT和BDNF五种基因与环境因素(如,母亲敏感性、压力性生活事件和家庭养育环境等)对儿童发展的交互作用,支持了差别易感性模型。但是,关于基因与环境交互作用的机制、携带易感性基因个体的种族和性别差异问题以及优势敏感性假说的验证,都是该领域未来研究的重要方向。     

拟人化:从“它”到“他”

拟人化是将人类特征、动机、意向或心理状态赋予非人对象的心理过程或者个体差异。拟人化的产生受到激发主体知识、效能动机和社会动机的影响,现有研究包括对自然、超自然、动物、机器、品牌和产品等的拟人化。对自然的拟人化能够促进环境保护行为,对动物、机器、品牌和产品的拟人化则形式多样、后果复杂。未来研究的焦点可能在人-机器人交互以及拟人化与可爱的关系问题上。     

不同内隐学习任务在不同认知风格个体上的成绩差异

通过两个实验,考察了不同认知风格大学生在人工语法任务、序列反应时任务中的成绩差异性表现。结果表明,场独立与场依存者在两类任务中内隐学习量的差异性表现一致,均无显著差异。进一步比较两种认知风格大学生在人工语法范式下内隐、外显及内隐外显协同学习类型中的差异表现时发现,场独立者的协同学习成绩优于单独的内隐学习和外显学习,且优于场依存者的协同学习。     

1993~2013年常驻高海拔地区军人心理健康状态的横断历史研究

研究为探索常驻高海拔地区军人心理健康水平如何随社会年代变迁而改变,运用了横断历史元分析的方法,对1993年至2013年38篇采用90项症状自评量表(SCL-90)的文献调查数据进行分析,考察了11454名常驻高海拔地区军人在该量表上9个因子得分随年代变化的趋势.结果发现:(1)SCL-90的7个因子均值与年代负相关,且不受期刊类型等的影响.20年来,7个因子下降了5%~15%不等.其中,强迫变化最大,抑郁、焦虑、人际敏感、偏执和精神病性均变化明显.这说明,常驻高海拔地区军人心理健康虽有所波动但整体水平逐步提升,变化幅度大致属于中等程度.(2)当年军费占GDP比值、居民消费水平指数与SCL-90部分因子均值负相关显著;5年前的居民消费水平指数与7个因子显著负相关.这说明,国防建设的经济投入和居民消费水平可能是影响常驻高海拔地区军人心理健康水平的重要因素.
