6 incredible brain tricks that hide the imperfection of our view

Feature of our vision – its discreteness (interruption). The reason for this is Saccada. These are microdvods of the eyeball, performed simultaneously in one direction. During them, a person bothers – does not see anything. Vision seems to be paused.

We do not notice the fact that vision is discrete, since our brain itself fills the gaps. He draws a picture, fills the missing fragments, fantasies.

Saccada is needed in order to constantly change the angle of view. We see due to the fact that the brightness of the objects around us changes.

How it is manifested

Our eyes constantly scan the surrounding space, looking for what you can cling. It must be something contrast – a bright spot, a protrusion, details. That is why it is pleasant to be in the forest, where many contrasts, considering interesting objects in terms of architecture, a variety of elements.

But monotony, homogeneity, the absence of elements for which it would be possible to cling to the eye, seems to us boring.

You know, I do not understand how you can go past the tree and not be happy that you see him?

2. Stretching time

What it is

Saccada have an interesting effect. After them we can feel a slowdown in time. This phenomenon is called chronostazis.

How it is manifested

If you look at the second analog clock arrow jumping from dividing to the division, its first movement will seem slower than the subsequent. This is because the brain slightly "slows down" after Sakkada. There is an illusion of stretching time.

An experiment associated with the perception of time was carried out by American scientists Chess Stetson and David Eagleman (David Eagleman). They issued wrist displays with large constantly changing numbers. With a small frequency, they could easily distinguish. And when the change rate has increased, the numbers merged into a homogeneous background

Scientists tried to prove that if a person is under stress, he will start to see some numbers again. According to their hypothesis, the brain otherwise perceives time in critical situations. Test jumped from a height of 31 meters on the safety net. The experience failed, however, most likely, stress was not so strong as it was necessary: ​​people knew that at the bottom of insurance and they would remain unhappy.

3. Hidden blind spots

What it is

In the eye of a person there is a blind spot – this is the area on the retina, insensitive to the light. In this place there are no light receptors due to the characteristics of the structure of our organ of vision. But we do not notice this, because the brain is deceiving us.

How it is manifested

When we look like both eyes, blind spots are invisible. The same if you close one eye. In this case, the brain "loads" the image that he takes from another eye.

But you can detect a blind spot. Use this picture:

  • Close the right eye and look at the left eye on the right cross, circled with a circle.
  • Not blinking, remove or bring the face to the monitor.
  • Side vision follow the left crossed, not looking at him.
  • At a certain point, the left cross will disappear.

4. Miscellaneous color perception

What it is

Central and peripheral vision perceive colors in different ways. The thing is that there are two types of photosensitive elements in the eye – columns (they better distinguish colors) and sticks (they have higher photosensitivity). Place of maximum cluster of colums – center eye. Sticks more on the periphery.

From here there is a feature of our view. Peripheral vision allows you to see in the semi and dark. It better catches bright, contrasting colors, such as black or red. But other shades perceives worse.

How it is manifested

Despite the difference in central and peripheral vision, we see a holistic picture. The final image gives birth to a brain that imagines, designed it from already available data. And not the fact that he is not mistaken and does not distort the reality.

5. Special perception

What it is

This is a psychological theory according to which we perceive the environment and events in it from the point of view of their ability to act. And it creates interesting visual illusions.

How it is manifested

Tennis players feel that the ball is moving slower if they are successfully chopped off. If a person needs to catch the ball, he will seem to him more. Mountains look cooler if you are going to go upstairs with a heavy backpack.

The speed of movement, the form, size of objects, as well as the actions are influenced by the speed of the movement,. All this helps to survive. And if you want to see what the subject looks like in reality, use the camera.

6. Overted vision

What it is

In fact, the image falls on the retina of the eye in the turned the form. The cornea and lens are collective lenses, which, according to the laws of physics, turn the items upside down. Information gets into the brain, and he processes it and adapts – so that we see the world as it is.

How it is manifested

There is a simple, but indicative way. Put a finger to the outer edge of the lower eyelid of the right eye. In the upper left corner you will see a stain. This is a present, inverted image of your finger – how does an eye perceives it.

The brain is able to adapt our eyesight. In 1896, Dr. California University George Stratton created an invertoscope that turned the image of the surrounding world. The one who wore this device saw the items as they fall on the retina.

Stretton found out that if wearing an invertoscope for several days, the visual system adapts to the inverted world, disorientation decreases. In this way, you can train a way to train spatial human spatial abilities.
