Scientists have come to surprising results. In addition to perceiving light, pupils can do another wonderful thing

Surely you know that the size of the pupil changes depending on the environment we are in, whether it is darker or lighter. However, scientists managed to discover wonderful news. It turns out that the size of the pupil also varies depending on how many things he sees.

The pupils also change depending on the number of items

The more objects we see, the larger the pupils will be than if you try to adapt and understand as much as possible, writes the portal Science alert. The latest research published in the journal also appears Nature ConnectionsIt’s an automatic reaction. In the research, researchers watched the pupils of 16 participants change, while they looked at pixelated pictures. In some figures, the points were connected by lines to resemble the shape of iron, creating the illusion that there were fewer objects in the figure. In the other figures, the points were shown separately.

Each time the participants looked at a pixelated image, their pupils contracted. According to experts, this is clear evidence that the pupils distinguish not only light, but also digital information. What does this mean for us from a practical point of view? For example, learning difficulties, including dyscalculia, that affect the ability to work with numbers are often difficult to identify. However, this method can help professionals to identify dyscalculia in time, even in young children.

Although the number of elements in the image has not changed, the way we perceive them has. Research participants were supposed to look at the pictures negatively, without trying to find out how many dots there were. Why does the student grow and decrease according to the number of things?

Help us survive

Experts believe it should help us survive. They believe that most animal species can perceive a number of things around them in a certain way. This allows them to quickly detect the enemy in their natural environment, find food or return to their territory. As far as people are concerned, we are able to perceive digital data a few hours after birth.

Although someone is really terrible at mathematics, they have an innate ability to perceive numerical information. When we look around, our brain automatically assesses how many objects are around us, how large they are, what color they are, and whether they are stationary or moving. This means that we share with other animals the ability to estimate how many apples are in the tree or how many enemies are about to attack us.

Our eyes seem more sensitive to the number of things in front of us than the way they are arranged. In addition, pupil size affects a number of cognitive processes. Although this is an important step forward for scientists, plenty of additional research awaits them. They are curious to know a number of other factors that can alter the size of the pupils.
