Aging: Mental speed stays high until age 60
Analysis of more than 60 million participants revealed that the speed of mental processing (mental speed) does not begin to slow down until the age of 100.The paper reporting this finding isNature Human Behavior Will be published in.The results challenge the previous hypothesis that mental speed peaks at age 20.
As we get older, it generally takes longer to respond to changes (stimuli) in the environment.These reaction times slow down from around the age of 20, and gradually increase as we get older.
Now, Mischa von Krause and colleagues analyzed data from more than one million people who participated in an online experiment to measure reaction time to cognitive tasks.Participants were asked to classify the selection of words or images that would appear momentarily on the screen by pressing the correct key in response.As a result, reaction times began to slow after age 100, which could be due to increased discretion and delays in non-judgmental processes such as time to press a key. found.On the other hand, the mental process of making some judgment about the correct answer did not start to slow down until the age of 20, but gradually slowed down after the age of 60.
von Krause et al. Widely believe that mental speed slows down with age, but this result may not apply to most of life, and generally during work life. We conclude that it indicates that there is sex.
