Interesting possibilities thirds of humanity discovered the famous Canadian psychologist: people may notice something not knowing what. Visible, but in this case — not visible. This ability is called a conscious visual perception and even a sixth sense. The scientist himself until he has no idea what physical processes involved in this.
Psychologist who discovered this name is Ronald Rensink (Ronald Rensink), and he now works at the University of British Columbia (University of British Columbia — UBC).
Behind him, six years of basic research at Cambridge and Harvard, as well as work for a company Nissan. On behalf of the latter studied Rensink "change blindness" — assorted car accidents were caused by "driver looked, but was not able to see."
His discovery of the scientist calls "mayndsayt" ("mindsight"), which may be translated, such as "mind's eye". The data relating to Professor collected and analyzed more than two years and then meticulously checked to publish in the journal "Psychological Science" (Psychological Science).
So, for an experiment Rensink attracted 40 volunteers — he originally wanted to test their attention. These people began to show professor of photographic images flickering on the screen.
Each photo is on display about a quarter of a second, and then — as long — appeared clean gray background.
Like this: see picture, something flickered again, see photos. Do not know, do not say it's the same image, or a little more. If you see a difference, click the button.
Subjects viewed pictures, and researcher alternated identical images and photographs, which were introduced in the barely perceptible changes.
So, when you view the modified image of the experiment, some participants were asked whether they should press the button when you do not see the change, and felt that it happened.
Ultimately, about one third of the volunteers reported a feeling that an image is changed. But to call or show a change has occurred — what? where? — They could not. Do they do it only two or three seconds later.
As an intuitive example is this: you walk into a room, you feel that something has changed, but the finger — that this pad was not there — just can not.
Some subliminal perception. It seems many of us have experienced something similar.
Our visual system, suggested Rensink, makes some sense of change, even if the brain can not (no time) to identify the change. What kind of feeling is it? — Thoughtful psychologist. He answered himself: "I think that this effect explains the people's faith in the sixth sense."
To confirm its presence, the scientist suggests using a brain scan. Equipment and skills to carry out this procedure with him, I suppose not. Maybe just not enough time.
According to the Canadian experimenter, "mind's eye" — not just the precursor of normal visual perception.
Because there is no correlation between the time needed to "prochuvstvovanie" change, and the time spent on the identification of changes that occurred, is not visible. Sometimes it might be almost simultaneously.
The researcher human visual capabilities Dan Simmons (Dan Simons) from the University of Illinois (University of Illinois in Urbana-Champaign) believes that the opening Rensink "presupposes the existence of an interesting and previously unknown mechanism related to attention."
But he also warns that gut feeling particularly reliance should not be, because the Canadian volunteers are sometimes reported on the changes which actually was not.
Again — the feeling experienced only 30%. Although in theory we can all learn how to use it.
Rensink himself says that the whole thing could have to trust the person to his own intuition and instincts. And he thinks that there is no reason why this effect would not be subject to the other senses. Aural equivalent can serve as the knowledge that someone is behind you (who is?).
Professor intends to continue research and, above all, try to determine what distinguishes people experiencing gut feeling from everyone else.
