Second, there are three main reasons for forgetting: recession theory, exclusion theory and interference theory.
1, decline
Things in the brain will fade with the passage of time, just like photos. Recession is of great significance in sensory memory, short-term memory and medium-term memory: it keeps the limited storage space unfilled. However, in theory, long-term memory has unlimited storage space, but we still forget the content of long-term memory, because memory exists all our lives, and the only question is whether people can call it up. In fact, the lost memory still exists, but it can't be found again. Like a key, it must be somewhere, but I can't remember where it is. By training memory, we can improve the chances of retrieving it.
Step 2 rule out
When information is too painful, humiliating or frightening, when people have extreme traumatic experiences, exclusion will appear. Fortunately, there are not many times of panic, because even memory training can do nothing. However, we can handle these unpleasant experiences or feelings quietly, which will improve our memory. For example, if we don't particularly like someone, we may remember his name better.
3. Interference
Interference is a process of frequent forgetting. When we are memorizing word lists with similar contents, because the contents are too similar, we find that the ability to memorize each word list shows an obvious downward trend. However, in view of this phenomenon, there are also remedial measures, that is, don't study similar content monotonously for too long. When reciting the English vocabulary list, you can have a rest after reciting some words, then learn some others, and then go back to recite words. In addition, the more meaningless what you want to learn, the more obvious the interference. So we must constantly try to find meaning through association.
