The brain removes unnecessary details from memory. Things that you don't pay attention to are not remembered. Five facts about memory.
Fact one. If we do not remember certain things on purpose, they begin to "fade" from memory. This is fine. According to researchers at the University of Toronto, absolutely everything should not be retained in memory.
Making decisions becomes easier when the brain gets rid of unnecessary things, like outdated information or trivial details. The brain focuses not on individual memories, but on the big picture, which makes our mind more flexible and allows us to quickly adapt to new situations.
The second fact. The word spins on the tongue, and you still can't name it. Sometimes our mind "freezes", and for a moment it is impossible to remember some aspect. As reported in studies of the 1990s, this happens to each of us at least once a week on average, and more often with age. In about half of the cases, the word is remembered in less than a minute.
Fact three. Don't remember where you left your keys or what they told you? The memory probably didn't form initially because you weren't focused on the situation and were thinking about something else.
Fact four. Shameful, stupid or unpleasant moments you remember very well, although you would rather forget. As reported in the dissertation work of Lund University, a person is able to learn how to deal with the memories that come to mind, just as a person is able to control physical impulses. However, the study only examined neutral memories.
Fact five … According to researchers, difficult memories are more difficult to deal with, and the possible consequences of such actions are not yet clear. However, such memories can be "covered" with new impressions, according to a study by the University of Cambridge.
