Human brain is not suitable for multitasking
"Multitasking" in which multiple tasks are executed in parallel may seem like an efficient task processing method, but multiple research results say "human brain can not do multi tasking" Professor of psychology at McGill University talks about its explanation and solutions.
Multitasking Is a Myth, and to Attempt It Comes at a Neurobiological Cost - YouTube
Professor Daniel Levitin of the Faculty of Psychology at McGill University says, "We tend to treat all things at once, but I will explain that such multitasking is a myth." According to Levitin,Miller Lab of Massachusetts Institute of TechnologyMany research institutes such as "it shows that the human brain is not able to multitask".
Performing multitasking seems to repeat that "I concentrate on one thing for a while" and that all tasks use brain resources, respectively. Efficiency declines because you are using "100%" concentration power for subdivision, and neurobiological cost is paid before you notice it when switching tasks. It is difficult to maintain concentration ability for a small hour when practicing multitasking, but because it used up neurochemicals in the brain necessary to concentrate.
Meanwhile, "Professor Levitin speaks that there is a profession that requires multitasking". Besides professor of psychology, Professor Levitin has titles such as air traffic controllers, simultaneous interpreters of the United Nations, journalists, etc. Both of these occupations are required to process different tasks at once. However, air traffic controllers said that it was decided to take a break of 15 to 30 minutes every hour and half hour during work. By going for a walk during a small break or listening to music, it is encouraged to restore the exhausted neurochemical during work, clearing the problem that "human brain is not suitable for multitasking" It seems to be.
In addition, it seems that there was a question "Human brain does not evolve to adapt to multitasking?", Evolution is not obtained by training, so from the speed of evolution of mankind so far In conclusion, Professor Levitin answers that it is after 20 thousand years that there is a possibility of becoming a human being adapted to multitasking.
To summarize Professor Levitin 's story, the trick to efficiently doing multiple jobs is to concentrate tasks one by one and to take short breaks frequently. With this, you will not waste your brain's resources and you will be able to maintain your concentration.
