Multitasking is such an important topic to speak about and discuss, while there is a big dispute in this point, some people think that it is just a time-wasting, while others believe that it is just a smart way to finish your tasks, I will try to tell you here about my opinion in this, and also tell you about many information maybe this is your first time hear it.
what is multitasking? well, even in the definition there is discord, some people say it is the concept that one can split their attention on more than one task or activity at the same time, such as speaking on the phone while driving a car. "don't do this", while others say that it is when someone tries to perform two tasks simultaneously, switch. from one task to another, or perform two or more tasks in rapid succession.
Since the 1960s, psychologists were trying to understand how the multitasking process is done, they were also discovering and searching in many sensitive points such as sex difference, for example, a Swedish study found that men outperformed women at handling multiple tasks simultaneously, with the performance gap being correlated to the female menstrual cycle. Or in 2018, a study in Norway tested everyday scenarios via videogames and found that "none of the multitasking measures (accuracy, total time, total distance covered by the avatar, a prospective memory score, and a distractor management score) showed any sex differences."
and the psychologists were also trying to understand the role of the brain in this process and according to a study done by Jordan Grafman, chief of the cognitive neuroscience section at the National Institute of Neurological Disorders and Stroke, "the most anterior part [of the brain] allows [a person] to leave something when it's incomplete and return to the same place and continue from there," while Brodmann Area 10, a part of the brain's frontal lobes, is important for establishing and attaining long-term goals. Focusing on multiple dissimilar tasks at once forces the brain to process all activity in its anterior. Though the brain is complex and can perform myriad tasks, it cannot multitask well.
another thing we should consider is that there is a switching cost, In the mid-1990s, Robert Rogers, Ph.D., and Stephen Monsell, D.Phil, found that even when people had to switch completely predictably between two tasks every two or four trials, they were still slower on task-switch than on task-repeat trials. Moreover, increasing the time available between trials for preparation reduced but did not eliminate the cost of switching. There thus appear to be two parts to the switching cost -- one attributable to the time taken to adjust the mental control settings (which can be done in advance if there is time), and another part due to competition due to carry-over of the control settings from the previous trial (apparently immune to preparation).
In 2010, a scientific study found that a small percent of the population appeared to be much better at multitasking than others, and these people were subsequently labeled "supertaskers". In 2015, another study supported the idea of supertaskers. This particular study showed that they tested people by making them drive on a driving simulator while at the same time memorizing words and solving math problems. As expected, most of the participants did much worse than their individual task test scores. The supertaskers, however, were able to multitask without major effects on their performance.
but wait a minute is multitasking affect our IQ? A study by the University of London found that participants who multitasked during cognitive tasks, experienced an IQ score decline similar to those who have stayed up all night. Some of the multitasking men had their IQ drop 15 points, leaving them with the average IQ of an 8-year-old child. So in the next time, you find yourself in a meeting, trying to juggle listening to your boss and reading the day’s top stories, know that little information will be stored from either tasks when all is said and done.
after all of this said let me tell you about my point of view, well my honest opinion is that: Basically there are some tasks you can do in multitasking mode, while on the other hand, you have some tasks that you can't do in multitasking mode or maybe it is just so early for the humanity to do it, well, I think that the human abilities can do the perfect multitasking one day, but how??, please don't ask me!
