“似曾相识”是人们大脑中知觉系统和记忆系统相互作用的结果
我是从心理学上找来的 是的。..我就是说的这样的.. 有时候甚至当你在做某件事情的时候``~ 总感觉这件事情是什么时候发生过..~具体我也不怎么清楚``帮你查了一下``希望能帮助到你
这是正常现象

你是否有过这样的经历:突然感觉眼前的场景无比熟悉,所有的一切每一个细节,甚至是接下来的所要发生的一幕,你都了如指掌,就好像曾经经历过。然而,事实上并非如此。据最近相关调查显示,有2/3的成年人至少有过一次这种“似曾相识”的经历。据北京大学心理学教授、博士生导师分析,“似曾相识”的感觉,在每个人身上都会发生:不过,如果这种感觉过于频繁,过于强烈就是一种病态。

知觉与记忆相互作用

“似曾相识”是人们大脑中知觉系统和记忆系统相互作用的结果。要想了解为何出现“似曾相识”的感觉,科学家得从知觉和记忆中的分类进行。分类的过程是知觉的一个基本特征,也是记忆的一个基本特征。知觉包括对面孔的知觉,对物体的知觉对位置的知觉等等。以这3类为例,由于它们的对象不同,因此,当我们到一个地方以后,方位和空间关系,周围的物体,人物,可能同时出现。然而,我们对它们的知觉却是由大脑中3个不同的空能回路,即位置知觉的回路,物体知觉的回路和面孔知觉的回路分别去完成。与知觉类似,记忆也分很多类型。
知识和感念的记忆被称为语义记忆:针对情节、经历、事情经过的记忆,即情景性记忆,这是无意识记忆。其中每一类记忆,又可以分为很多个子类。正因为知觉和记忆都是“分类”进行的,我们曾经经历的一些场景的众多特征存放在不同的记忆系统中,而我们无法意识到,当我们走到一个新的场景,场景中的某些部分就可能会刺激我们的一些记忆,调动大脑中并不同的记忆系统和与之相匹配。一旦场景中的某一特征和过去的经历匹配上,就会产生“似曾相识”的感觉。生活经历每个人都会有,因为积习的东西很多,偶尔出现“似曾相识”这种主观体验是很正常的现象。对“似曾相识”这一主观体验的最初认识可从医学上的癫痫病开始,可以追寻到半个世纪以前,正常人也会出现这种主观体验,随着脑科学知识的积累逐渐达到了今天的认识水平。

多发生在情绪不稳定时
