There were many more errors when the distraction came during the reading time than when it came during the solving period.
So believe Michigan State University psychologists who tested 60 volunteer students by ringing a doorbell at various times while they were reading a set of problems, again later as they worked on the answers. Here's another surprise finding: You do more brainwork preparing to solve a problem than in actually solving it. The conclusion: Your brain, unlike a machine, uses most of its energy "merely in keeping its circuits alive and sensitive," and needs insignificantly little more when you use the circuits.Īt What Stage of Problem-Solving Does The Human Mind Work Hardest? The finding: virtually no change throughout. University of Pennsylvania investigators believe this is so after checking on brain-energy requirements by measuring oxygen consumption in a group of subjects while they idled, did problems or slept. One of the most surprising recent discoveries is that you apparently use little more energy when you think than when you don't. But recent research provides some new facts about how our brains work. Wide differences of opinion exist among investigators who are trying to probe its mysteries to establish basic facts. As a subject for scientific study it presents infinite intricacies and difficulties. Of all things known in the universe, the human brain is by far, the most complex. How much energy do you use when you think? At what time of day is your mental performance best? Does talking to yourself help your thinking? Are your thoughts influenced by body position? If you have an exam to take, or some problems to solve, how can you let the human mind work, without your realizing it, to find the answers?
