The first example: Cell phone use while driving is at least a contributing factor to more than one-in-four car accidents across the country. (The news by Ryan Gorman The DailyMail public on 27 March 2014)
The second one: Listening to your boyfriend/girlfriend gossiping while watching TV and saying you are listening to him/her instead of listening what is on the TV.
We think that we can do those things at the same time but actually it is not in our brain. The Neuroscienctist at MIT, Earl Miller, said.
“People can’t multitask very well, and when people say they can, they’re deluding themselves. For the most part, we simply can’t focus on more than one thing at a time.”
The only thing that we can do is shifting our focus from one thing to the next with a very quickly speed. It shows that you cannot focus on one thing while doing the other because there is actually the interference between the two tasks such as we send an email while taking on the phone, you will notice that there is a slow down on the speed of typing.
In conclusion, if we really look into the brain, the brain will pause for awhile after the first task and then perform another task because it takes time to push aside the information about the previous task.
In my experience, I cannot really do two things at the same time like studying and listening to music but some of my friends they said they could. Let’s share your idea!
