Scientists Explain Why Our Brains Deceive Optical Illusions


A 14,000-year-old hunting tool in France in the past weeks made optical illusion figures back on our agenda. Now, researchers have uncovered how the optical illusion figures that have come to the fore again mislead our brains.

Optical illusion figures have been in our lives for a very long time. The number of people who do not know the rabbit-duck figure, one of the most famous optical illusion figures, may be almost nonexistent.

We have recently shared with you the news of the bison-mammoth optical illusion figure on a 14,000-year-old hunting tool in a cave in France. Both a bison and a mammoth were seen in the 14,000-year-old optical illusion figure.

How do optical illusions work?
So how do optical illusions manage to confuse many of us? To find the answer to this question, researchers from Carnegie Mellon University conducted a study on how optical illusion figures affect how people experience and pre-thought concepts affect the way we decide between uncertain options or fill in missing information.

Sandra Buhlman, one of the researchers, says the universe that the brain learns through experience is a critical period. Buhlman says that the nerve cells that process the visual scenes in the state of vision are a process of development of plasticity in which the individual strengthens the connections depending on what they experience.

To put it another way, our brains are not just experiencing the places and things we see. The brain also establishes a link between the thought and context represented by places and things seen.

Optical illusions can become more trickier as we get older
As we age, the experience relationship between visual circuits and the contexts of thoughts settles firmly. For this reason, when we look at an optical illusion figure at an advanced age, we see only one option, and to see the other option, an external stimulus is usually required.

Children’s brains, on the other hand, are less configurable than adults, and show less resistance to new and different ways of thinking. This enables children to be more successful against optical illusion figures.

As we mentioned above, the link between optical illusion and plasticity is not a new concept for humanity. The optical illusion figure in the cave in France shows that people’s knowledge of these figures dates back thousands of years.

The mammoth-bison optical illusion figure represents the heritage of thousands of years ago as the entertainment and puzzle figure of art for humanity. Nowadays, encountering this illusion and seeing one of the mammoth or bison figures can provide moments that will enable us to dream about the development of humanity.
