It is obvious that future memory formation is strengthened by moving experience


Emotional experience influences memory formationAlthough it is known to be known, it became clear that the formation of memories on events newly experienced in "After receiving inspirational stimulation" by emotion has been strengthened.

One group of researchers,FMRI"How do the moving experience affect the formation of memories?" Was examined.

In order to find new discoveries, researchers conducted a survey using fMRI. Subjects were divided into three groups, one group gave "inspirational stimulus" for 23 minutes, after 9 minutes of rest, they gave "emotionally neutral stimulation" for 23 minutes . In the second group, the order of giving "inspirational stimulation" and "emotionally neutral stimulation" to the first group is reversed, in the third group the break time between 9 minutes and 23 minutes .

In the experiment, apart from fMRI, in order to investigate whether the subject is emotionally awake, the skinConductanceWe measured the level. Researchers assumed that the influence of emotion affected the break time, so the skin conductance level is presumed to be the same high value as the case of receiving a stimulus immediately before the cutaneous conductance level. Then, when actually looking at the numerical values, it was proved that the guess is correct. In other words, when experiencing an emotional event, it became clear that the influence was dragged even after the impression.

Furthermore, it is also clear that "emotionally neutral stimulus" may be related to how long it is that impression influences memory. It is said that "How much time does impression influence memory," judged by asking quizzes about events that occurred during breaks when 6 hours passed since the experiment. And the result of this quiz is that the skin conductance level and the correct answer rate seem to match in most cases. In other words, the results of the tests have made it clear that the formation of memories on events experienced in "After receiving inspirational stimulation" has been strengthened.


Furthermore, it is also clear from the results of fMRI that there is a strong connection with a part of the brain during emotional stimulation and break time.

Researchers have said that it is not clear which element of the experiment is necessary to obtain the same result as this time. For example, it seems that it was totally arbitrary to extend the break time from 9 minutes to 23 minutes. Besides, it is unknown whether the subject intentionally tried to remember the event, and it is unknown what kind of influence the result had on the result.
