Reptiles see optical illusions the same as humans
Source:Lizards can be fooled by the optical illusion.
In mid-2019 on the Internet , which everyone perceive differently. For example, someone claimed that it is the color, and someone thought that it is black and white with colored lines. Such images, which are capable of deceiving human vision, called optical illusions and famous people a few thousand years. They work on people because of the rather complex structure of the human eye, which is blind zones and other features. Optical illusions can deceive the sight, and other animals like monkeys, but nobody had ever imagined that they likewise react even reptiles lizards. But they do not have a developed vision with a complex structure.
About the unexpected discovery, made by Italian scientists, was described in a scientific journal called . According to researchers, the eyes of some reptiles can be cheated at least known optical illusion Delibera. She was first depicted in the XIX century and consists of two filled circles of the same size, which are surrounded by big and small rings. While viewing this image, people think a filled circle inside the large ring is smaller than the second circle. But in fact they are exactly the same.
Illusion Delibera
How to cheat vision?
Previously, scientists found that this optical illusion in addition to people . The discovery was made during the experiment, where the primates were given two identical plates of food. The only thing that distinguish them is the radius of the circle drawn around each saucer. The researchers suggested that when the monkeys first come to the plate in a small circle, so their vision was deceived. It happened — the animals went into the little circle, because the plate inside it seemed to them great.
Bearded Agama (Pogona vitticeps)
About the same way, the Italian scientists tested the performance of illusion and reptiles. Their test involved 12 bearded Agam (Pogona vitticeps), and land turtles 8 coal (Particle carbonaria). In the first part of the experiment they had set two identical dishes with a vegetable puree which we spread out to form circles with a diagonal of 4.9 and 1.8 inches. As expected, the reptiles first came to the plate, where food is more.
Coal turtle (Head carbonaria)
A kind of illusion Delibera was recreated only in the second part of the study. At this time, animals were put plates of different size and portion of food were the same. The effect worked perfectly on the lizards — their vision was clearly deceived and they came to a small plate. And this despite the fact that a big plate was imposed the same amount of food.
But turtles, for some reason, did not understand what the plate of food more and approached the two plates in all directions. Perhaps this is due to the fact that their eyesight is not as good as in lizards. From this it follows that to be deceived by optical illusions are not all reptiles.
