记忆的顿悟优势效应指, 与加工非顿悟问题相比, 加工顿悟问题能够产生更优的记忆保持量。该效应在顿悟的两种操作性定义以及不同实验材料中稳定出现。基于顿悟阶段观, 研究者提出两种理论解释记忆的顿悟优势效应的认知机制:认知的生成效应和表征转化理论认为, 顿悟加工过程中的认知努力、适当迁移加工以及顿悟的表征转换加工促进记忆的保持效果; 情绪的“啊哈”体验理论认为, 加工顿悟问题后的情绪对后续的信息提取具有促进作用。未来的研究可从优化顿悟的指标、巩固记忆的顿悟优势效应、评估其持续性以及更加系统探讨记忆的顿悟优势效应的认知机制等四个方面展开。 相似文献

When examinees' test-taking motivation is questionable, practitioners must determine whether careless responding is of practical concern and if so, decide on the best approach to filter such responses. As there has been insufficient research on these topics, the objectives of this study were to: a) evaluate the degree of underestimation in the true mean when careless responses are present, and b) compare the effectiveness of two filtering procedures in purifying biased aggregated-scores. Results demonstrated that: a) the true mean was underestimated by around 0.20 SDs if the total amount of careless responses exceeded 6.25%, 12.5%, and 12.5% for easy, moderately difficult, and difficult tests, respectively, and b) listwise deleting data from unmotivated examinees artificially inflated the true mean by as much as .42 SDs when ability was related to careless responding. Findings from this study have implications for when and how practitioners should handle careless responses for group-based low-stakes assessments. 相似文献

Young children's self‐benefiting lies and their relation to executive functioning and theory of mind 下载免费PDF全文
It is well established that children lie in different social contexts for various purposes from the age of 2 years. Surprisingly, little is known about whether very young children will spontaneously lie for personal gain, how self‐benefiting lies emerge, and what cognitive factors affect the emergence of self‐benefiting lies. To bridge this gap in the literature, we situated children between 2 and 4 years of age in a zero‐sum game where children must lie to their opponent if they wanted to win a desirable reward. We found that the majority of young children did not lie even when they experienced personal losses repeatedly. However, some children spontaneously lied during the game; as the game progressed, more children lied. Further, we found that children's theory of mind understanding and executive functioning in terms of a combination of inhibitory control and cognitive flexibility had significant positive and unique correlations with how frequently children lied for personal gain. The present results taken together with the existing findings regarding children's lies for self‐protection and politeness purposes suggest that the act of lying begins early in life. Further, its emergence and development are influenced by children's specific cognitive abilities in the domains of theory of mind understanding and executive functioning.
Highlights
- The study investigated whether very young children will spontaneously lie for personal gain.
- This study used a zero‐sum game to elicit children's self‐benefiting lies. Results showed the majority of young children did not lie, and it is related to children's theory of mind understanding and executive functioning.
- The act of lying begins early in life, and its emergence and development are influenced by children's specific cognitive abilities in the domains of theory of mind understanding and executive functioning.

许多证据表明权力在大脑中是以垂直空间来进行表征的, 具体而言为言语和视觉空间编码。前人研究发现两种编码具有情境依赖性, 即当前任务决定了激活哪种编码。一般的词类判断任务主要依赖于言语编码。然而仍不确定的是, 当排除言语空间编码后, 词类判断任务能否激活视觉空间编码。本研究拟借助双任务范式探讨此问题。实验结果发现单任务条件下出现权力-空间交互, 并且双任务条件下, 这一交互只受到视觉空间次要任务的干扰。这说明, 词类判断任务也可依赖视觉空间编码, 并进一步支持了权力空间表征的情境依赖性。 相似文献

听觉、时间加工能力与发展性阅读障碍 总被引:1,自引:0,他引:1
近年来阅读障碍者的知觉加工越来越受到重视 ,本文介绍了近期国外关于阅读障碍者的听觉加工能力、时间加工能力的最新研究进展。快速听觉加工能力的缺失在阅读障碍者身上普遍存在 ,并被认为是阅读障碍产生的主要原因 ;有研究者提出“时间控制障碍”假说 ,认为阅读障碍源自一种普遍性的时间知觉障碍 ,不具有通道特异性。除此之外 ,还发现阅读障碍者对声音频率、响度等非时间特征也出现了觉察困难。通过这些研究我们可以看到 ,听觉加工能力、快速时间加工能力与阅读能力之间可能有着密切的关系 ,但这几种能力如何具体作用于阅读发展 ,它们之间如何相互作用、相互影响仍需进一步探讨。 相似文献
