Perform multiple tasks at the same time multi-task is such efficiency is likely to accumulate bad stress pointed out , but have been carried out, with the latest research, "multi-task is illusion, to believe that doing multitasking improve performance "The report was shown.

Since multitasking that performs multiple things at the same time uses a lot of brain power, problems such as adversely affecting productivity and memory and causing mental problems are pointed out .

Also, "multitasking" has not actually happened, and the claim that people do not "do a lot of tasks at the same time" but rather "only do one thing at a time by switching tasks" It exists. Shalena Srna of the University of Michigan who studies consumer behavior also agrees with this point and says that "multitasking is a matter of cognition and something like illusion".

On the other hand, Mr. Srna said in a new study "Multitasking is an illusion, but the effect of that illusion is real, it increases performance in cognitive tasks."

Research that investigated the performance of multitasking has existed so far, but Srna's research unique is to investigate how the perception that "I am doing multitasking now" affects performance Place

According to Mr. Srna, in previous studies, it has been shown that if the task becomes difficult, people will have "motivation to strive" and "cognitive control" will increase. Indeed, with multiple research results, the person who performed the challenging task raised the attention and the result as the result, from which the recognition that "performing multiple tasks" can improve the real performance Sex is considered. Conversely, concentrating on only one task is considered "do not require attention, effort, cognitive resources", and performance may be reduced.

In order to investigate this hypothesis, researchers conducted multiple surveys targeting more than 8000 subjects in total. All subjects were subjected to the same task, but the difference was made whether to do in multitasking or in a single task.

For example, in one test, subjects divided into two groups, multitasking / single task, performed a task of viewing an educational movie and transcribing its contents. In addition, it is said that the test of viewing online lecture in the state of multitask / single task was also conducted.

As a result, in many tests, the subjects who thought "I am doing multitasking" got good results. These subjects performed transcription quickly and accurately, took high-quality notes, and said that they recorded a high score with quizzes.

In the experiment, pupil dilation was examined by eye tracking in order to measure the attention and mental effort of the subject. Although researchers have acknowledged that such methods are "limited" in accuracy, people reporting that multitasking workers have a larger average pupillary dilation compared to those who do single tasks It is. This indicates that the mental effort of the multitasking person is greater.

Of course, this research does not mean that "multitasking is superior to single task", but in spiritual sense multitasking seems to bring effort and concentration to people.
