意外考试悖论的博弈分析

本文从博弈的角度分析了意外考试悖论,指出了以往解决方案的不足,给出了一种新的方案。根据这个新方案,考试悖论的推理中使用了倒推法和弱下策反复剔除法。本文接着讨论了这些博弈推理方法的不足。然后把这个新的博弈方案用到卡片悖论和方格悖论这些考试悖论的变种里。最后指出,在考试悖论里,比起倒推法,弱下策剔除法是引起悖论的更根本的原因。     

多动症儿童与认知事件相关电位的实验研究

本研究通过对29名多动症(MBD)儿童与正常儿童认知事件相关电位各成份的比较,结果发现多动症组与正常儿童组在反映大脑认知功能P300潜伏期有明显的差异,从而说明P300可以作为检测多动症儿童的参考性的客观指标。     

IAT效应在不同目标概念水平上的差异研究

采用IAT实验设计,考察大学生对不同概念词的内隐态度之间的差别。结果发现,八组实验材料都产生了显著的IAT效应;不同性别的测验材料的IAT效应间不存在显著差异,不同喜好程度的测验材料的IAT效应间存在显著差异,且两个因素存在显著的交互作用。研究表明,IAT效应既可在上位概念水平上产生,亦可在下位概念水平上产生。     

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。     

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.

成就目标对青少年成就动机和学业成就影响的研究

本研究在迈尔（Maehr）等人研究的基础上,考察了成就目标（任务目标和能力目标）与动机和学业成就之间的关系。结果表明,任务目标通过内部动机对学业成就产生积极的影响,能力目标通过外部动机对学业成就产生消极的影响。     

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.
