学习后睡眠有利于记忆巩固,学习的类型不同,睡眠依赖的记忆巩固机制可能也有所不同,涉及到不同脑区在不同的睡眠时相的生理功能。睡眠有助于长时程增强（long-term potentiation,LTP）的形成,进而促进记忆的巩固。总睡眠剥夺、快动眼睡眠剥夺、片段性睡眠可以通过不同的分子生物学机制损伤记忆巩固。 相似文献

睡眠剥夺对小鼠学习记忆和免疫功能的影响 总被引：1，自引：0，他引：1
应用水迷宫学习模型测试慢性不完全睡眠剥夺组动物和正常对照组动物的空间学习记忆能力,并计算出两组小鼠的胸腺指数和脾脏指数.结果发现,慢性不完全睡眠剥夺组动物与正常对照组相比,动物到达水下平台的时间和游程明显增加（P＜0.01）;动物的胸腺指数显著减小（P＜0.001）.说明慢性不完全睡眠剥夺导致小鼠学习记忆能力下降和免疫功能减弱. 相似文献

在我们的工作和生活中,记忆起着非常重要的作用,这是通过识记,保持,再现(再认,回忆)等方式在人们的头脑中积累和保存个体经验的心理过程,它是一种积极能动的活动,是保存个体经验的形式之一,在个体的心理发展中也有重要的作用。记忆和学习是密不可分的。人们都渴望能有一个好的记忆,尽量减少遗忘。在教学实验中,将探讨检验学习类似材料时彼此的干涉作用,进一步研究前摄抑制和倒摄抑制形成的原因及影响,探讨在学习活动中如何克服其负面的影响作用。通过探求人遗忘的机制,从而指导人们如何减少遗忘,提高学习效率。 相似文献

个体差异的实验室研究历来在学习和记忆领域占有较为重要的地位，生理缺陷、智力水平、年龄等因素都可能引起学习和记忆的个体差异，它们一方面体现了学习和记忆的相关特征，一方面也促使学习和记忆向更细化的方向发展。从内隐学习、内隐记忆、前瞻记忆和错误记忆四个领域展开讨论并集中分析个体差异的主要影响因素以及它对学习和记忆多重加工机制的促进作用，这种思路和方法在未来的研究中是至关重要的。 相似文献

It is known that rapid eye movement (REM) sleep plays a crucial role in learning and memory. Previous studies have demonstrated
that postlearning REM sleep deprivation (RSD) impairs memory consolidation. Most of these studies observed only the effects
of RSD on learning and memory. In the present study, we not only investigated the impacts of 48-h RSD on the spatial reference
memory of young rats in a Morris water maze, but also specifically examined whether an REM rebound for 24–48 h after 48-h
RSD affected the maintenance of spatial reference memory. RSD was induced by the modified multiple platform method, and spatial
reference memory was tested in a Morris water maze. The results demonstrated that, compared with the control groups, posttraining
RSD for 48 h produced a significant impairment in the retention of acquired spatial reference memory, and the impairment continuously
existed after 24 and 48 h of release from sleep deprivation, which indicates that REM sleep plays a critical role in reference
memory maintenance and consolidation. Moreover, postlearning RSD may lead to a long-term impairment in the consolidation of
newly acquired memories. 相似文献

Transformative learning as explained by Mezirow in the field of adult education has been criticized as a process that is overly dependent on critical reflection, such that it minimizes the role of feelings and overlooks transformation through the unconscious development of thoughts and actions. This paper further substantiates these concerns by exploring the emotional nature of rationality and unconscious ways of knowing (implicit memory) from the field of neurobiology and psychology and offers a physiological explanation of the interdependent relationship of emotion and reason and the role of implicit memory in transformative learning theory. Recent research not only provides support that emotions can affect the processes of reason, but more importantly, emotions have been found to be indispensable for rationality to occur. Furthermore, brain research brings to light new insights about a form of long-term memory that has long been overlooked, that of implicit memory, which receives, stores, and recovers outside the conscious awareness of the individual. From implicit memory emerges habits, attitudes and preferences inaccessible to conscious recollection but these are nonetheless shapes by former events, influence our present behaviour, and are an essential part of who we are. Finally, based on these new insights for fostering transformative learning is discussed, revealing the need to include practices inclusive of ‘other ways of knowing,’ and more specifically, from the study of emotional literacy and multiple intelligences. 相似文献

工作记忆与学习能力的关系 总被引：1，自引：0，他引：1
工作记忆是一种对信息进行暂时加工和贮存的能量有限的记忆系统,工作记忆通过阅读理解、写作和数学问题解决而影响学生的学习能力。语音回路对阅读的影响更多地体现在复杂句子结构的理解上,中央执行功能在语言意义的加工过程中起着更大的作用,写作能力的逐步完善与工作记忆能力的增长密不可分,工作记忆的三个成分对简单和复杂数学问题解决都产生重要影响。 相似文献

Research on teachers' efforts to influence the ways in which children approach memory tasks and understand and regulate their own memory processes has been limited, possibly because of the restrictive views of memory held by cognitive theories that have previously guided research efforts. A more complex perspective on the memory skills that develop over the elementary school years has been elaborated by developmental psychologists and information-processing theorists, but their work has had limited influence on either teacher-training practices or research in teaching. In order to begin to apply this newer perspective to an understanding of classroom teaching processes, research needs to consider teacher practices and expectations for children's learning and memory. A program of research that has been concerned with how teachers teach memory and metacognitive skills and with teachers' views of memory processes is summarized in this article, and implications for teacher training are discussed. 相似文献
