Recently, the media reported on the unusual experiment by Sydney University professors Alan Snyder and Richard Shi. They have developed a method that makes a man smarter for a short time by stimulating the brain with direct current. In their experiment, the stimulation takes 10 minutes. And I’ll prompt method that works instantly. Without any technical devices.In their experiment, Australian scientists have proposed to solve the good old puzzle: nine points must be connected by four straight lines without lifting the pencil from the paper.
If you have already worked with this puzzle – below we will discuss how to use this experience to other tasks. If not – try to solve it just for fun. I remember that the very first time I met this problem in the pages of the magazine “Nauka i zhizn” (“Science and Life”) in Soviet times: editorial argued that the problem has been proposed to hundreds of Drs, and only 5% of them have managed it.
That was the puzzle that Sydney University researchers used to demonstrate the effectiveness of the developed by them “safe and noninvasive” (without penetrating the body) method of stimulation of the temporal lobe of the brain, which for a short time improves understanding and memory of the subjects. In the end, after 10 minutes of stimulation 40% of the participants in the experiment could solve the task with nine points!
By the way, more than a year ago I wrote in this blog about the device to stimulate the brain designed by Alan Snyder. I still stand with my opinion: such methods should not be used as a “full-energizer” for managers, engineers, scientists, students and so on. It’s not just the immediate and long-term risks to health of the people who are constantly exposed to stimulation. Society, which in peacetime forces its members to go beyond the natural capacity of the human body is doomed to regress.
At the same time, one-time stimulation of the brain, in my opinion, can sometimes be useful. For example, it can help a person to “see” beyond his usual mental “ceiling”, learn to enjoy the process of thinking, to expand the personal experience of “mental victories.” But we talk only about situations when a person stopped at an impasse in his personal development. Or when he overcomes the effects of the disease. In all other cases, one can achieve success in a natural way. Just exercising. Simply allowing himself to think without restrictions.
I too, at one time managed the task with nine points, just “allowing” myself to solve it. After several unsuccessful attempts, I reread the problem statement. There was a sacramental phrase at the end such as not everyone is able to go beyond the usual range of solutions. This phrase has suddenly worked as a hint, I immediately found the answer. You had really to go “outside the circle”, in the literal and figurative sense (if you did not find a solution – you can peep what I mean).
The same thing happened to many of my friends. After the first unsuccessful attempts to more than half of them were easy to find a solution as soon as I mentioned, that they need to “go beyond the sample solutions.”
From this experience, I have derived a simple heuristic algorithm that helped me many times in my life:
1. find the limits of habitual in this problem;
2. look for a solution outside of these boundaries.
Let’s take for example the split with the help of this algorithm still one robust nut more.
On this video, Doctor of Biological Sciences Dmitry Kavtaradze offers a special way to “confuse” the clutch and wrung hands – and then try to move the middle finger of his left hand. According to the doctor, most people have difficulty performing this trick, because the brain is faced with an unfamiliar situation for which it does not have samples.
Yes, as long as you concentrate on the “tangle” of tangled fingers, the problem seems strange and unfamiliar. But try to “go beyond the terms” – to shift your attention to where you are not hard to distinguish the right from the left hand. For example, you can focus on your left wrist – and in this new area of concentration to send a mental command to lift your index finger. Is not it – now the trick go right from the first time and with no effort?
