Several reports have referred to it as an “extended hole” illusion. This dynamic illusion consists of black dots, which are like small elliptical balls on a white background. There is a black patch in the center of the image without any definite outline. This fuzzy black patch looks like a hole and it starts to expand when you fix your eyes on it.
The report states that although it is clear that the black hole in the middle of the image continues to expand until we look at it, 20% of people do not understand this expansion. This sharp difference between the observers calls for attention to be paid to the correct understanding of the process behind how this illusion works.
What people see in Maya
As explained earlier, most people find that the black patch or black hole tends to expand when we look at the image. Black holes create an illusion of a hollow dark matter that is constantly scattered around the black elliptical balls on a white background.
However, others who do not realize the above illusion see it as a black stain of ink. This illusion does not realize the elastic person expansion.
What researchers say about illusions
The researchers explained that the rate of change in the diameter of the pupils is significantly related to the illusory motion.
“At the root of this bright / dark illusion is the fact that, in general, the perception of light is not directly related to the physical parameters; A research report explains optical illusion In May 2022, the study was published in Frontiers in Human Neuroscience.
“Typically, when looking at the pattern below, observers’ thematic reports are characterized by perceptions of a slowly expanding central region, occurring in a matter of seconds,” the researchers said, adding that about 20% of participants in the study did not understand illusory expansion.
The study was performed on 50 people with normal eyesight. Participants were asked to determine the illusion of motion or the extent of the black hole’s expansion, and these predicted the degree of expansion of the student measured with an eye tracker.

Those who changed the diameter of their students more rated the severity of the illusion as higher. There was no change in the puppet diameter of those who did not notice any change.
Researchers have come to the conclusion that the expansion or contraction of students is not only driven by our surroundings, it is also driven by our own imagination and perception.
