Memory
Memory is the recognition, retention, representation or recognition of the experience of the human brain, which is the basis of higher mental activities such as thinking and imagination. Human memory is associated with changes in the structure of the hippocampus and the chemistry of the brain.
Memory is the human brain’s reflection of what has been experienced. The so-called experience of things, refers to the past perception of things, such as seen people or things, heard voices, smelled, tasted taste, touched things, thought, experienced emotions and emotions. The process of transforming abstract disorder into pictorial order is the key to memory
Memory, like perception, is the brain’s response to objective reality, but memory is a more complex psychological phenomenon than perception.
Memory can be short-term or long-term. In short-term memory, your mind stores information for a few seconds or a few minutes: the time it takes you to dial a phone number you just looked up or to compare the prices of several items in a store. Such memory is fragile, and it' s meant to be; your brain would soon read “disk full” if you retained every phone number you called, every dish you ordered in a restaurant, and the subject of every ad you watched on TV. Your brain is also meant to hold an average of seven items, which is why you can usually remember a new phone number for a few minutes but need your credit card in front of you when you' re buying something online.
Long-term memory involves the information you make an effort(conscious or unconscious) to retain, because it' s personally meaningful to you ; you need it , or it made an emotional impression .
Some information that you store in long-term memory requires a conscious effort to recall: episodic memories, which are personal memories about experiences you' ve had at specific times; and semantic memories.Another type of long-term memory is procedural memory, which involves skills and routines you perform so often that they don' t require conscious recall.
记忆是人脑对经验过事物的识记、保持、再现或再认,它是进行思维、想象等高级心理活动的基础 。人类记忆与大脑海马结构 、大脑内部的化学成分变化有关 。
记忆作为一种基本的心理过程,是和其他心理活动密切联系着的。记忆联结着人的心理活动,是人们学习、工作和生活的基本机能。把抽象无序转变成形象有序的过程就是记忆的关键 。
关于记忆的研究属于心理学或脑部科学的范畴。现代人类对记忆的研究仍在继续,尽管当今的科学技术已经有了长足的发展。运用那些经过实践后能有效提高记忆力的方法、技巧,可以使之更好地服务于人类的工作、生活、学习中。
