启发信息对个体顿悟问题解决影响的眼动研究

本研究以火柴棒算式问题为实验材料,采用2(问题类型:问题A、问题B)×2(启发类型:有、无)×2(认知风格:场独立型、场依存型)×5(兴趣区:第一个加数、加号、第二个加数、等号和结果)实验设计,考察顿悟问题解决时个体的眼动差异。结果发现:相对于场依存型个体,场独立型个体能够更有效地利用启发信息来减小表征变换时的心理加工负荷,进而提高加工效率;启发信息促进问题解决者对问题的表征从数值表征转变到符号表征,从而成功地产生了顿悟。     

任务转换中的反应-反应相容性效应

采用任务转换范式,分别以阿拉伯数字奇偶判断和组成汉字词的汉字结构一致性判断为任务,通过两个实验探查了不同类型材料在任务转换中的反应—反应相容性效应。结果发现:(1)材料类型对反应—反应相容性效应有影响,任务转换前阿拉伯数字材料存在反应—反应相容性效应,汉字词材料不存在反应—反应相容性效应;(2)任务转换时段对阿拉伯数字奇偶判断任务的反应—反应相容性效应没有影响,转换前后阿拉伯数字奇偶判断任务都存在反应—反应相容性效应;(3)任务转换时段对汉字词任务的反应—反应相容性有影响。转换前没有反应—反应相容性效应,转换后存在反应—反应相容性效应。     

不同学业成绩类型学生的抑制控制研究

根据全市三次统考平均成绩及科任教师对学生学习能力的综合评定,选择小学三年级、五年级、初中二年级、高中二年级学生为被试（各80人）,共320人。每个年级的80人中,又分别包括四种类型（每种类型20人）,进行抑制控制测量。结果发现：抑制控制力与学业成绩有高度的相关,即（1）双优生两种抑制控制测试成绩最好;相反双差生的两种抑制控制测试成绩最差,二者差异非常显著。（2）两种偏科的学生的两种抑制控制测试成绩处于中等,二者有些项目差异显著,有些项目差异不显著。（3）双优生与两种偏科生相比,除个别项目之外,差异也十分显著,而两种偏科生与双差生相比有差异,但表现在两种抑制控制测试中各个项目的程度不一样。     

小学优生与差生完成系列回忆任务错误类型发展的实验研究

主要探讨了小学优生与差生在完成系列回忆记忆任务时出现错误的发展情况。实验以小学一、三、五年级的学生作为被试,每年级优生与差生各10名。以普通(不形似,不近音)、形似和近音三种类型汉字为实验材料,要求被试按材料呈现的顺序进行回忆。结果发现：在完成系列回忆任务时,小学生表现出四种错误类型,错误率从高到低依次是：移动错误、遗漏错误、侵入错误、重复错误。每一类型的错误率都是优生显著少于差生。研究还发现四种错误受材料特点的影响,即各年级小学生错误率从高到低近音字、形似字、普通字。     

关于假设-验证和范畴化认知方式与学业不良的相关研究

该研究采用自行设计的能力问卷量表,结合教师问卷、个案访谈和调查等方法对80名小学四年级学生、94名初中一年级学生、85名高中一年级学生,共259名被试进行了假设一验证和范畴化认知方式与学业不良关系的研究。结果表明：各学习年限段学业不良学生在这两方面的得分均低于学业优秀者,且差异显著;各学习年限段学业不良学生间在这两方面的得分差异显著,呈随年龄增长而增长的趋势。     

父母婚姻冲突对青少年抑郁情绪的影响:一个有调节的中介模型

采用整群抽样法选取宁波市四所中学初一至初三共537名学生为被试,以问卷调查法考察父母婚姻冲突与青少年抑郁情绪的关系,同时探讨心理韧性的中介作用,以及该作用是否受到社会支持的调节。结果发现：（1）心理韧性在父母婚姻冲突与青少年抑郁情绪之间起部分中介作用;（2）社会支持调节了父母婚姻冲突通过心理韧性影响青少年抑郁情绪中介过程的前半路径和后半路径。研究结果揭示了父母婚姻冲突影响青少年抑郁情绪的内部机制,对增强青少年心理韧性的强度以及减少抑郁等情绪问题具有重要的理论与实践价值。     

Fitts’ Law is modulated by movement history

Fitts’ Law is one of the most robust and well-studied principles in psychology. It holds that movement time (MT) for target-directed aiming movements increases as a function of target distance and decreases as a function of target width. The purpose of this study was to determine whether Fitts’ Law is affected not only by the demands of the target on the current trial but also by the requirements for performance on the previous trial. Experiments 1 and 2 examined trial-to-trial effects of varying target width; Experiment 3 examined trial-to-trial effects of varying target distance. The findings from Experiments 1 and 2 showed that moving a finger or cursor towards a large object on a previous trial shortened the movement time on the current trial, whereas the opposite occurred with a small object. In contrast, target distance on the previous trial had no effect on movement time on the current trial. These findings suggest that performance on trial n has a clear and predictable effect on trial n+1 (at least for target width) and that Fitts’ Law as it is normally expressed does not accurately predict performance when the width of the target varies from trial to trial.     

Black–White mean differences in job satisfaction: A meta-analysis

Studies examining Black–White mean differences in job satisfaction have provided little clarity regarding whether there are meaningful differences between the two racial/ethnic groups on this job attitude. The present study sought to reconcile prior inconsistent findings via a meta-analytic synthesis of this literature (N = 753,791; K = 63 independent samples from 55 studies) and examined whether moderators explained the observed variability in effects. Using Hedges and Vevea's (1998) random-effects meta-analytic approach, we found that, on average, White workers were slightly more satisfied with their jobs than Black workers (g_corrected = .09; 95% credibility interval = −.21 to .39) and this effect was larger in more nationally representative samples (g_corrected = .24). The substantial true variability around this effect suggests the presence of moderators and the need for caution in interpreting the overall effect as it likely does not generalize across all work settings. Data collection year, geographic location within the U.S., job sector, and measure type were not found to moderate Black–White mean differences in job satisfaction. However, job complexity and sample demographic composition did significantly moderate this relationship. Our results show that the magnitude and direction of Black–White mean differences in job satisfaction are influenced by the context.     

A moderated mediation analysis of children’s physical activity enjoyment

Grounded in expectancy value theory (EVT), a moderated mediation model predicting children’s physical activity (PA) enjoyment was tested. Ability beliefs and subjective task value were initially investigated as mediating the relationship between social support from friends and PA enjoyment. It was hypothesized that children play an active role in this socialization process with support seeking self-efficacy moderating the mediated relationships. Findings revealed PA social support from friends and PA enjoyment was mediated by PA ability beliefs, but this mediated relationship was conditional on children having average-to-high levels of support seeking self-efficacy. The mediated relationship between PA social support from friends and PA enjoyment through subjective task value was not moderated by support seeking self-efficacy. Results support the importance of instilling confidence in children to seek out PA support in order to maximize opportunities for PA enjoyment and suggest pathways may be more complex than originally posited in EVT.
