The higher a person's IQ, the more he looks and notices the details. And vice versa - at low IQ a person pays attention only to the large, voluminous, large-scale, they are convinced. For example, scientists say, a sage will notice a fly on an elephant, but will not be impressed by the elephant itself.
The researchers based their claim on a series of experiments they conducted. 65 volunteers with IQs from 80 to 140 watched videos in which black and white figures of different sizes were constantly moving in different directions and now appeared, now disappeared. The largest figures predominated in the center of the field of view, and the smaller ones were grouped in the background and at the edges of the frames.
The movement of the figures on the screen was so chaotic and spontaneous that the participants made a lot of effort to be able to quickly determine the direction of the objects. And so it became clear that the higher the IQ of the volunteer, the easier it was to track the smaller objects in the background.
"High IQ helps the brain filter information better, which explains why smart people are more attentive to detail," said study leader Prof. Tadin. In some situations, this ability is a big advantage - for example, when in a crowded office you have to concentrate on working with a computer. But the concentration of the highly intelligent also has its drawbacks, he added. Their inability to ignore the "elephants" leads to the fact that such people become maladapted to life, says the professor.
That is why genius minds need faithful helpers who notice the "elephant" in time and do not allow him to step on the talent.
However, distraction is unique to people with high intelligence, say researchers at the University of Glasgow. They have found an excuse for those who often find themselves in awkward situations during conversations, as they are always out of class and talking nonsense. This is not a sign of low intelligence, the problem is in hearing and more precisely in listening, scientists say.
"The habit of listening with half an ear is a defensive reaction," said Professor Hartmud Lesolt of the University of Glasgow. "The thing is, most of us often don't pay attention in conversation because we subconsciously protect our brains from overexertion," he explains.
In today's world of global information invasion, the brain is not able to constantly and fully process all the messages that attack it from hundreds of sources - the Internet, radio, television, text messages, advertising posters, and billboards. Otherwise, it would fail quickly, scientists say. To protect himself from unnecessary information, he began to save his resources. And then we begin to listen absentmindedly even to our loved ones, highlighting only a few keywords. For this reason, we are often out of date with the topic of conversation.
"This is especially true for people who spend a few hours every day on the Internet. They have learned not only to read but also to listen "diagonally", explains Prof. Lesolt.
Quick concentration test
Do you want to know if your interlocutor is listening to you carefully? Ask him the following question: "How many animals of each species did Moses take in the ark?" If he answers "Two of each kind", then he is listening to you with half an ear. Because this is not true - not in terms of the number of animals saved, but in terms of the one who saved them, because the ark was built by Noah, not Moses.
Scientists claim that more and more people asked about this "Illusion of Moses", as the test is called, immediately answer incorrectly. And only after thinking about it do they discover the discrepancy in the biblical names.
