Molecular biologist and University of Washington professor John Medina told us about his book, Brain Rules. In it, he presents 12 "rules" to boost your brain power, based on what scientists know for sure about how our brain works.
Some rules are obvious, like 5. Repeat to remember (short term) and 6. Remember to repeat (long term), and some are quite unexpected. Like multi-tasking, for instance:
Multitasking, when it comes to paying attention, is a myth. The brain naturally focuses on concepts sequentially, one at a time. At first that might sound confusing; at one level the brain does multitask. You can walk and talk at the same time. Your brain controls your heartbeat while you read a book. Pianists can play a piece with left hand and right hand simultaneously. Surely this is multitasking.
But I am talking about the brain’s ability to pay attention. It is the resource you forcibly deploy while trying to listen to a boring lecture at school. It is the activity that collapses as your brain wanders during a tedious presentation at work. This attentional ability is not capable of multitasking.
