According to a new study published in the journal Science, this myth is completely new to science Boundaries in Human Neuroscience.

The first author of this study was Bruno Lang, a professor of psychology at the University of Oslo.

– The developing hole is a very dynamic illusion. The circular dot or shadow in the center of the black hole gives a clear impression of the optical flow, as the observer moves forward into a hole or tunnel, he says in a document. Press release.

The experience was affected

The illusion that the student’s light reflection, which controls the size of the student in anticipation of expected changes in light, depends on the perceived environment rather than physical reality.

This means that the student’s reflexes depend on perception (experience) and not on reality itself.

– Although this “light” is as imaginary as in the illusion, here we show how the student responds not only to the amount of light energy actually entering the eye, but also to how we see the light, Long says.

A simple trick reveals the liar

If you look at the myth of the “expanding hole”, according to the professor, your pupil will expand just as it becomes darker around you.

One in seven did not see the illusion

The researchers also explored how the color of the hole and the surrounding dots may affect how it reacts to the illusion.

They did so by showing 50 normal-looking women and men different variations of the image, asking them to assess how strongly they understood the illusion. At the same time, the researchers measured their eye movements and pupils.

– Take care of the onions when you cut

The illusion is most effective when the center “hole” is black.

Of the participants, 14 percent did not understand the expansion of the central space. 20% did not see the myth when they got dirty.

The researchers also found that black “holes” cause students to expand, while colored “holes” narrow students.

I do not know why

With black holes, students further developed when participants experienced a perception (perception) of illusions.

It is still a mystery to scientists why some people do not understand the illusion of a growing hole.

– Something strange is happening in the universe

When students expand or contract, the results show that no information other than the actual amount of light affects the light receptor, which is not a fully automatic process like opening a photocell door, the professor commented.

– Instead, the eye corresponds not only to physical energy, but also to perceived – imaginary light. Future studies may reveal other types of physical or physical changes that shed light on how illusions work, he says.
