学龄儿童的情景记忆与心理理论的关系

为考察学龄儿童心理理论与情景记忆的关系,111名小学4-6年级儿童在两周内完成了心理理论(包括二级错误信念、失言和白谎等)和情景记忆(回忆过去"一个星期内"、"一个月内"和"一年内"亲历的具体事件;以及想象将来"一个星期内"、"一个月内"和"一年内"可能发生在自己身上的具体事件)等任务。控制了年龄效应后,线性回归分析发现儿童回忆过去时"谈及他人"、想象将来时"谈及自我"和"谈及他人"与心理理论的认知成分存在显著关联。而儿童回忆过去时"谈及他人"与心理理论的情感成分有显著关联。结果表明,学龄儿童心理理论可以分为认知成分和情感成分,情景记忆与心理理论不同成分的关系存在差异。     

提取练习在记忆保持与迁移中的优势效应：基于认知负荷理论的解释

提取练习比建构概念图更有利于记忆保持和迁移的研究结果尚存在争议。依据认知负荷的3个成分,设计两个实验探究前期知识水平与策略复杂性对以上两种学习策略有效性的影响。结果表明：(1)前期知识水平的主效应不显著,但是与学习策略之间存在交互作用：在提取练习策略条件下,高前期知识水平的被试与低前期知识水平的被试在记忆保持和迁移上的正确率没有显著差异,但是在建构概念图策略条件下,高前期知识水平的被试在记忆保持和迁移上的正确率显著地高于低前期知识水平的被试;(2)当降低概念图的难度后,被试使用建构部分概念图策略产生的认知负荷与使用提取练习策略相比显著降低,并且其在学习阶段学习到的知识量显著地高于使用提取练习策略的结果,但是在最终测试上,其记忆保持与迁移的正确率与使用提取练习策略并没有显著差异,策略的复杂性增加了学习者的额外负荷,但是对策略有效性的发挥却不具有决定性影响。以上结果说明提取练习策略之所以比建构概念图策略更具优势,不是因为其策略本身更易掌握,而是因为其与建构概念图策略相比不受学习者前期知识水平的影响。这意味着认知负荷理论可以很好地解释提取练习在记忆保持与迁移中产生优势效应的内部机制,并进一步证实提取练习与精细编码不同,具有独特的加工机制。     

中学生厌学心理及其干预与学习效率的相关研究

本研究旨在考察两个问题：1．心理咨询是否是改变中学生厌学心理的有效途径,如果是,它能够在多大程度上改变厌学心理;2．厌学心理的改善能否有效提高中学生学习效率。本实验用问卷调查法从183名中学生中筛选出有厌学心理的学生24名。运用个体心理咨询、团体心理咨询等手段对这24名学生进行为期4个月干预、结果表明：心理咨询能够有效且明显地改善厌学心理。但要完全消除厌学心理则还需要辅以其他干预手段;随着学生厌学心理的改善,其学习效率也相应有了明显的提高。     

家庭游戏中的母亲控制策略与儿童顺从行为

以42个3岁儿童及其母亲为被试,考察在家庭自由游戏中母亲的控制策略和儿童的顺从行为之间的关系。结果表明：（1）在亲子交往中,母亲使用直接命令的频次最多,间接命令次之,否定控制最少。（2）3岁儿童对母亲控制的顺从率为56．1％;在儿童的不顺从行为中,无技巧不顺从占优势,其中消极不顺从的频次最多。（3）母亲的弱控制策略与儿童的顺从行为相关最高;强控制策略与儿童的无技巧不顺从相关最高。（4）在儿童不顺从时,母亲的弱控制策略容易导致儿童的顺从行为,强控制策略则容易导致儿童的情境性顺从行为。     

大学生实时距、空时距估计的比较研究

本研究采用2(空时距、实时距)×8(1秒～8秒)的实验设计,以224名大学生为被试,考察了不同类型、不同长度的时距估计特点,结果发现;(1)时距类型在时距估计中存在主效应,在本实验中,1秒～8秒条件下实时距估计比空时距准确;(2)时距长度在时距估计中存在主效应,时距估计所产生的误差随时距长度的增加而增大;(3)时距类型与时距长度之间存在交互作用,对实时距、空时距估计进行曲线估计及预测,发现两类时距估计呈现动态特征,1845052秒之前实时距估计比空时距准确,之后空时距估计比实时距准确,两类时距估计曲线的变化速度也呈交替上升趋势。     

对肾移植输血问题的思考

就肾移植受者输血的几个问题进行了回顾和探讨。提出肾移植受者输血应该考虑的问题有：如何权衡输血对肾移植受者的有益作用与输血风险,输血医学的发展如何为肾移植提供更有力的保障,应该深入探讨输血有益于肾移植的机制,推进供者特异性输血在我国的应用。     

个人目标相关性对非临床抑郁者未来想象的影响

通过两个实验考查了非临床抑郁者未来想象的异常是否受到个人目标相关性的调节。实验1采用未来想象任务, 实验2采用可能性评估范式, 两个实验一致发现, 抑郁倾向者想象未来积极事件的异常, 受到了与个人目标相关性的调节：相对于非抑郁倾向者, 抑郁倾向者对未来与个人目标相关的积极事件的预期减弱, 而对未来与个人目标无关的积极事件的预期则没有表现出异常; 同时还发现, 抑郁倾向者表现出了对未来消极预期的普遍增强, 不受与个人目标相关性的影响。     

浅谈健康危险因素评价

健康危险因素评价是研究危险因素与慢性病发病及死亡之间的数量依存关系.进行健康危险评价对传播健康知识,提高社会对健康危险因素的认识,促使人们改变不良行为和生活方式,减少危险因素,提高健康水平和生活质量,具有重要意义.     

Positive Affect,Self-Efficacy,Goal-Related Variables,and Life Satisfaction: the Role of Goal Attainment and Domain Value

The present study sought to extend work on subjective well-being using Lent’s (2004) model. Specifically, the role of goal attainment in the academic and social domains, and the value accorded these domains, in the pathway to life satisfaction was examined using self-report data from 354 Singapore university students. Results demonstrated a role for goal attainment and domain value. For goal attainment, it was found to be able to predict life satisfaction and to play a mediating role in the pathway to life satisfaction – specifically for the link between domain goal progress and domain satisfaction – although the full serial mediation model (from positive affect to life satisfaction) was supported only for the social domain. As for domain value, a moderating role was found in one instance, where the value of benevolence in the social domain moderated the link between social satisfaction and life satisfaction. Overall, the inclusion of both goal attainment and domain value can thus enable a better understanding of subjective well-being.

     

In search of the ‘Aha!’ experience: Elucidating the emotionality of insight problem‐solving

Although the experience of insight has long been noted, the essence of the ‘Aha!’ experience, reflecting a sudden change in the brain that accompanies an insight solution, remains largely unknown. This work aimed to uncover the mystery of the ‘Aha!’ experience through three studies. In Study 1, participants were required to solve a set of verbal insight problems and then subjectively report their affective experience when solving the problem. The participants were found to have experienced many types of emotions, with happiness the most frequently reported one. Multidimensional scaling was employed in Study 2 to simplify the dimensions of these reported emotions. The results showed that these different types of emotions could be clearly placed in two‐dimensional space and that components constituting the ‘Aha!’ experience mainly reflected positive emotion and approached cognition. To validate previous findings, in Study 3, participants were asked to select the most appropriate emotional item describing their feelings at the time the problem was solved. The results of this study replicated the multidimensional construct consisting of approached cognition and positive affect. These three studies provide the first direct evidence of the essence of the ‘Aha!’ experience. The potential significance of the findings was discussed.
