People who know themselves must also have a scientific basis in time in time.

How is your memory of the past? Maybe you still remember the happy dinner at the time of graduation. When you think of a happy past, you might smile, and temporarily forget your troubles. Or, the sweet marshmallow fragrance will make you recall the beautiful time when you are traveling with your parents. So, how do our brain perceive these vivid memories?

In recent years, scientists have been trying to search for the "marshals" in the brain's brain areas. Dr. Guo Siqi, an associate professor of Cognitive Neuroscience of Kunshan Duke University, has recently discovered a new discovery. They published a dissertation in Cognitive Neurology Journal, and put forward new opinions on the brain's ability to summarize experience in the basic aspects of our lives.

During the research process, team members found that humans can evaluate the vitality of their memory, and this evaluation process can be interfered by stimulating the corner of the brain. Guo Siqi explained that when people recall the past, they may remember many details of things. The past is as if in the movie screen, which is shown in the brain and has more aftertastes. This is the embodiment of memory vitality. But it should be noted that the more vivid memories are correct. The horn region is an important joint zone in the back of the brain, and it is a brain area that is very important for the subjective experience of memory. When a person's horn is hurt, it will not affect the quality of memory, but it will affect people's judgment of memory vitality. There may be one thing that I remember, but it is impossible to remember the details.

In addition, researchers also found that people's ability to evaluate the vitality of memory is different from self -confidence judgment on memory accuracy, which indicates that our brain has at least two meta -cognition (that is, awareness of their own thinking process). Treatment of memory subjective experience. "These two meta -cognition refers to the self -confidence assessment of their memory and the subjective and vivid judgment of memory." Guo Siqi added instructions.

The research team believes that according to this research results, we can improve the way of perceiving our own experience, such as helping to identify our mistakes and guiding future behavior. It is what the ancients said that people must have self -knowledge, but more importantly, "internal introspection".

Zou Fuxi, a member of the team and a doctoral student of the Cognitive Neuroscience of Oregon University, said: "The results of this research have given the potential research direction in the future. When assessing our own memory, in addition to vividness, what other information is used for meta -cognitive meta -cognitive . This research direction is expected to provide new insights on improving the path of this internal and intimable capabilities. "
