Test for Illusions: Optical Illusions Test. Illusions of perception Tests based on optical illusions

An illusion, in the literal sense of the word, is a distorted perception of a real object. In addition, many of us spend our entire lives creating illusions for ourselves, and then experience disappointment.

Illusion Test

We suggest you go through a very interesting illusion test.

Everyone knows the expression “Don’t believe your eyes.” However, many understand it in a figurative sense, while our eyes often really deceive the brain.

Optical illusions test

We do not set ourselves the goal of explaining the biophysical basis of this phenomenon. However, it is known that optical illusion can be explained by the specific effect of light reflected from objects on the human retina.

How to pass the “Illusion of Deception” tests

Test picturesIllusions should be done when the brain and eyes are rested after a hard day at work. The fact is that scientists have proven the connection between a person’s intellectual fatigue and a deterioration in the ability to actually perceive surrounding objects and phenomena.

In particular, it is known that with severe fatigue, some stationary objects begin to “move.” More precisely, the brain incorrectly deciphers the signal coming from the eyes, and a still picture seems animated to it.

People who, when looking at a still picture, see rapidly rotating circles should especially think about it. They should take this as a signal that they urgently need rest. Otherwise, they may have serious health problems.

An expert site explained how it actually works

Have you already taken the test by Japanese psychiatrist Akiyoshi Kitaoka, which determines the level of fatigue based on an optical image? No? Then go ahead!

According to the given algorithms, if when you look at the drawing, it appears static, then congratulations! Your psyche is stable and you are not tired.

If slight fluctuations are noticeable, then you need rest. Is the ball spinning at the speed of a Formula 1 racing car? It's time to see a doctor. On the face - depression and psychosis...

The portal site asked psychologist and women's trainer Ksenia Ulyanova to comment on the test parameters.

How does optical illusion work?

“To answer the question about the reliability of the test data, you need to understand how the optical illusion works. You look at a picture and nerve cells - neurons - transmit information to the brain. Pictures of this kind, as a rule, have dark elements or generally dark colors. They also include various complex geometric shapes, they are complex and contrasting.

These are very important points because colors, contrast and complexity of a picture slow down the brain. Information obtained from such complex pictures arrives with a delay, so there is time for self-deception. This happens due to the slow reaction of our brain,” commented Ksenia Ulyanova.

Don't believe me? Look at other psychological tests Akiyoshi Kitaoka uses to determine the level of fatigue. The principle is the same.

Is this a diagnosis?

Of course not!. First you need to conduct the study several times at different times of the day. If the data coincides in the morning, at lunchtime and in the evening, this is a reason to board the train and disembark by the sea. Otherwise, the fears are unfounded. Well, to calm your soul, you can go for a massage.

“I conducted experiments and found out that in the morning the picture is calm or even static. Why? Our brain is rested and works more efficiently: it perceives information faster thanks to the good functioning of nerve cells. In the evening the movement is more noticeable because the person is tired.

Thanks to such tests, you can determine your level of fatigue, but it is impossible to make a diagnosis on this basis alone,” concluded Ksenia.

Pencils
How many pencils? We count first at the top, then at the bottom

Helicopters
Can you tell which line is longer? Test yourself with a ruler. And then - by helicopters.

Night sky
We look at the moon for a long time, and the stars should disappear. How many stars did you manage to “not see”?

Colored spiral
Count how many colors you see? Most people see four: green, blue, and 2 types of pink.



Vanishing square
When small circles intersect with large ones, it is as if we see a shining and changing square. But in reality there is nothing like that. Our brain just tries to visualize the edges and fill the void with an object.

Gray lines
Even though you don't believe it, these lines are straight and parallel.

Birds
These two birds are identical. Not only in size, but also in color. Don't believe me?

Arrows
What do you see here at first glance? Yellow arrows to the left, or green arrows to the right? There is no correct answer, but different people see different arrows at first

Blue spiral
Cool spiral? They are actually circles. Swipe your finger across the screen (at the same time brush away the dust)

abyss
A little more and it will fall... into the paint

Wave
Where are the lines longer and where are they shorter?

Three illusions in one!



Red circles (classic)
We look at the cross, and soon the circles will be green

swaying
Move your mouse over the image. It's swaying!

Which way is the cat spinning?

and the dancer?

If you see a dancer spinning clockwise, then you are using more of the right side of your brain, and vice versa. This is something of a visual deception, because in fact, no matter which direction the dancer rotates for you, you will be right.
Left hemisphere: Logic.
Processing verbal information: Language ability. This hemisphere is responsible for speech, writing and reading abilities, as well as for remembering facts, names, dates and their spelling.
Analytical thinking: Logic and analysis. More precisely, an analysis of all the facts. It also recognizes numbers and mathematical symbols.
Sequential information processing.
Right hemisphere: Feelings.
Processing nonverbal information: Processing information that is expressed in symbols and images.
Imagination: Dreams and fantasies. It is this hemisphere that helps us write stories and is also responsible for our abilities in music and drawing.
Parallel information processing: Simultaneous processing of various information. It makes it possible to consider the problem as a whole, without the use of analysis.

Which direction is the train going?


If the carriage moves to the right, your left hemisphere of the brain is developed. And if to the left, then the right hemisphere.

Which point is in the center?


Which car is bigger?

Reality
a minute of viewing turns your walls and all objects around into plasticine

How many people did you see?

Are the lines parallel?

Points

Are there any points?

You need to fix your gaze on the points and move your head back and forth

Look at this picture.... what do you see?
This is Einstein!!! But if you stand up and move 5 meters away from the screen, you can see how he turns into Marilyn Monroe.

Some people see that the girl is spinning clockwise, and others see it counterclockwise, BUT IF YOU TRY, YOU CAN MAKE IT SPIN IN ANY WAY, you just need to imagine it well! If it seems to you that initially the girl is spinning counterclockwise, your right hemisphere is more developed, and if she is spinning clockwise, your left hemisphere is more developed. If you were able to make it spin in the other direction, you can be proud of yourself! Hint: look at the leg along the axis of rotation, and the key point is when the legs line up in one line, then you need to strain your imagination and imagine that the leg that should be “closer to you” turns out to be “further away”. In general, it’s hard to describe, but you’ve been given a hint!

It's easier to switch if you roll your eyes a little.

This test with a girl is a decoy, if you look closely, you will see that at certain intervals she is spinning in one direction and then in the other, and this happens so quickly that the human eye does not have time to readjust, so some people think that she is spinning to the right, some to the left, and especially observant ones both here and there.

Without a doubt, this test is just a “dummy” and is not related to the hemispheres, as previously stated!

Quickly moving a flat pattern left and right creates the illusion of moving in a circle, which is not actually the case...

Therefore, depending on factors such as blinking the eyes, turning the head, creating a preliminary image in the mind of left- or right-hand rotation, or simply moving the gaze down or to the side,
disrupts the cyclical perception of the intellect and thereby changes the illusion of perception...

But what’s interesting is that, indeed, there are people who, seeing this picture for the first time, at the very first moment, notice it spinning only in one certain direction, until you explain to them what’s what!

Thus, it may be interesting to find out how many of your friends (at the very first moment) observe the “circling”\”rotation” of the figure (which in reality does not exist) clockwise or counterclockwise, and estimate their percentage of the total number of test takers. ..

Only the primary vision, the first glance, can say something about the habitual Left-Right-hemisphere perception of a person...

We all remember well the popular optical illusion of a spinning girl. Animation has become so popular that I wanted to find something like it. The first time I didn’t even see the optical illusion, the train was moving to the left, but as soon as I turned my gaze to the barrier, the train began to move to the right. Experiment; you don’t have to look at the barrier; it works very well when you look at the wheels and immediately look at the carriage. Comment on your experiments.

The picture you are looking at now is black and white. But if you want, your brain can easily make it colorful. To do this, just look at the point for a while, after that your brain will do the rest itself.
