Why do we not hear what is in reality
Sometimes we hear something completely different from what we are told.
Our vision and hearing work in pairs, and, if the visual information contradicts the sound,
the brain prefers the one that gets through the eyes.

There is one interesting illusion that cannot be overcome even if you know what the matter is.
This is the MakGurk effect- the phenomenon of perception, which proves the relation
between hearing and vision.

In the video, the man pronounces the same “ba” sound, but first you see how the lips move correctly - precisely, to pronounce “ba”.
And then the picture changes as if the man says “fa,” and you really start to hear that sound.
However, he himself does not change. Try to close your eyes and see for yourself.

This works not only with individual sounds, but also with words.
Such illusions can lead to quarrels and misunderstandings, and even to more terrible consequences.
For example, if you mix up the sentences He’s got a boot and he’s gonna shoot.

There is another interesting sound illusion, not connected with sight and speech,
the effect of an approaching sound.
If the sound increases, a person is inclined to believe that he is closer if the volume decreases,
although the location of the sound source does not change.

This feature is easily explained by the desire to survive: if something comes nearer,
it is better to consider that it is closer in order to manage to escape or hide.

How do taste buds cheat us
Studies show that our taste sensations are also not the most reliable source of information.
So, wine connoisseurs were given turning white wine into red to try the same drink.
In the first case, it was ordinary white wine, and people indicated its characteristics.
Then red food dye was added to the same beverage and given again to the participants of the experiment.This time, connoisseurs felt the characteristic features of red wine, although the drink was the same.

Even the color of the dishes can affect the taste of food. The study showed cup color influences
taste of hot chocolate, when hot chocolate was served in a cream or orange cup, it seemed to
the participants sweeter and more fragrant than in white or red dishes.

It works with any drink: yellow cans enhance the taste of lemon, blue soda quenches thirst
better than red, and pink seems sweeter.

If it is so easy to deceive taste sensations, it can be assumed that tactile perception cannot
be trusted either.
be trusted either.
How tactile sensations can deceive us
This proves the famous rubber arm experiment. The person puts his hands on the table:
he puts one behind the screen and leaves the other in plain sight.
Instead of the removed arm, a rubber limb is placed on the table in front of him.

Then, the researcher simultaneously strokes the rubber arm and the real one,
hidden behind the screen. After some time, the person begins to feel that the rubber limb is his hand.
And when the researcher hits it with a hammer, he gets very scared.

And when the researcher hits it with a hammer, he gets very scared.
What is especially interesting is that during this experience the brain ceases to consider the
hidden hand as its own. Scientists measured the temperature of the limbs during the experiment,
and it turned out that the hand behind the screen was colder, while the visible hand and legs were
equally warm.

The visual picture deceives the brain, and it slows down the processing of information from a real hand.
This proves that the sensation of the body is closely connected with the sight and thinking.

Imperfect and our perception of weight. Dark objects seem to us heavier than bright ones.
Scientists have tested this effect. It turned out that with the same weight and shape,
a dark object seems to be 6.2% heavier than a light one. Keep this in mind when choosing dumbbells.

Despite all the illusions and distortions, we are used to trusting our senses to
allow ourselves to doubt them. And this is right, because we have no other sources of information,
nor will there be.

Just remember that sometimes even direct experience of perception can be wrong.

No, I haven't.
Have you watched something like this from personal experience?
I can't recall anything in particular but I can't think how it can be possible-after all whenever you move your lips to say "fa" you will automatically produce "fa" and not "ba" - only in video can you put the sound over image falsely, in real life it cannot actually happen.
Have you observed perceptual traps with other sensory organs?
Sometimes with smell - when some food automatically starts smelling bad after the due date, however often it smells exactly the same way as the day we bough it - it's just the
date that is messing with our minds.
No, I have never heard anything about the McGurk effect.
Have you watched something like this from personal experience?
I'm not a fan of something like that. I found it so annoying for me to watch, how our body react to this kind of experiments. When something similar to this happens, i feel not ok, my body starts to feel anxiety.
Yes, I've watched both of your attached videos before so I'm a little bit familiar with the topic.
Sometimes when I know that some food is after the expiration date it seems to stink more but it's identical.
I agree with the theory
2. relatively often this topic appeared in popular science programs. So I'm familiar with this topic.
3. The sensation of temperature comes to my mind. In the autumn when it is 10 degrees it seems to me extremely cold and I wear a jacket. At the same temperature in the spring I wear a T-shirt and it seems very pleasant to me.
4. Everything indicates that the theory is correct.
I have heard of this effect, and it seems logical to me. Even if you try, you cannot take over your brain's settings, and it will continue processing data as is. And this data flow may well be controlled.
No, I haven't. This is the first time I hear the name of this effect, but I've seen similar videos with this effect.
2. Have you watched something like this from personal experience?
I heard about some similar effects but never experienced them on my own.
3. Have you observed perceptual traps with other sensory organs?
First, which comes to my mind is when, you think, that hand/leg/eye is itching it really start itching.
4. Do you agree with the theory?
I agree with the theory.
No, I've never heard the exact name of this effect. But I googled)
Have you watched something like this from personal experience?
Perhaps, I probably didn't focus on this.
Have you observed perceptual traps with other sensory organs?
Very often, the nose picks up strange smells. Sometimes when I go out and close my eyes I catch with my nose the smell of the past.
Do you agree with the theory?
Yes, I agree with the theory. But this is still a theory, even though it is used for speech recognition programs, but it seems to me that it doesn't affect all people.
2. I think so, although at the moment I can't give an example.
3. Of course, even an illusion of sight. Op-art and elements that move in our eyes and are in fact motionless.
I hear about it first time, i like thing like McGurk effect and how did you write in presentation”Try to close your eyes and see for yourself.” it’s funny :)
2.Have you watched something like this from personal experience?
When you a car fun you have a problem with sounds of engine or braking or suppression, so you riding with you friends in 4 and listen to music, talking and then you hear something, and decrease the volume of music, told to shut up and open the windows, and then you understand that that time is anything okay:)
3.Have you observed perceptual traps with other sensory organs?
Close your eyes and ask you friend to open hot or ice water on your hand, 2-3 seconds you will not understand is it hot or ice :)
4.Do you agree with the theory?
i am agree with it
Honestly, I started doing this only after I saw a man in white on the street, who disappeared under the light of a lantern. It was very scary and disturbing. I thought that I was losing my mind, or maybe this is alien? But having studied the question, I realized that my brain had deceived me.

My favorite illusion is the one with rubber hand. It's so hilarious. Watching it on video it seems so ridiculous it cannot be true.
Yes I have. I have come across the videos you attached some time ago.
Have you watched something like this from personal experience?
Yes, I did watch the videos you posted
Have you observed perceptual traps with other sensory organs?
Yes, especially with food and smell. As others said, you may feel that food stinks when you see that it is expired but in the end it tastes the same
Do you agree with the theory?
Yes, I do
I've experienced the effect that distorts what our ears hear, ive experienced how our smell sensor can deceive us when exposed to to much smell every sense we have can deceive us in some way, sometimes even more than one and yet without them we re nothing. Thats why its important to care for all of them equally as they complement each other and provide us with tools for future discoveries.
Yes, I watched a film that was among other about this effect.
2. Have you watched something like this from personal experience?
I have never seen it personally, but in a film.
3. Have you observed perceptual traps with other sensory organs?
I don’t know if optical illusions count, but I have seen quite a lot of them. I can’t really think of anything else. It is very interesting how easily our brains can be fulled. It can teach a lot about how brains work.
2. No, but I would like to try it.
3. At the moment I do not associate anything like that.
4. Yes, It seems to make sense.
Yeah, thats very interesting that brain tricks us. It seems to me that something like death in movie matrix is possible.
Have you watched something like this from personal experience?
No, however I really would like to try
Have you observed perceptual traps with other sensory organs?
Tricky question for a male
Do you agree with the theory?
Very interesting. worth agreement
1. Nope, unfortunately I have never heard anything about the McGurk effect.
2. I really do not think I will experience anything like this. At least I can't remember.
3. I think deja-vu - the feeling that one has lived through the present situation before. I often have deja-vu and it is sometimes a great feeling.
4. Yes, I agree with this theory, because in my opinion every theory is supported by solid evidence, like this.
Yes, but i did not know what this thing was called.
Have you watched something like this from personal experience?
Hm, rather not, I once saw an animation with a woman spinning, when it was possible to change the direction just by thinking diffrently, while animation was the same. What is interesting, I was able to change direction multiple times.
Have you observed perceptual traps with other sensory organs?
Only with optical illusions. It is interesting how much everything in our bodies is connected with each other and have influence on each other. Our brains seem to have weakness on these tricks, habbits are superior to reality.
Do you agree with the theory?
Yest i agree with the theory.
No haven’t watched something like this from personal experience. I only saw some documentary movies and some illusionist in tv, and they show you how easily you can be manipulated if you meet wrong person.
Maybe hearing, when you heard running water and now you must go to bathroom
2. Basically everything about movie making is an art of illusions. So yes, a plenty.
3. I find that memories of a smell tend to trigger when there is none. For example I can often smell sulphur while holding an egg even when its perfectly fresh.
4. Sure.
No, I've never heard it, but I see that this is very interesting. I would like to read about it more . Thank You for that topic
2.Have you watched something like this from personal experience?
No, never but I want , do You have some interesing moves or documents about this topic ?
3.Have you observed perceptual traps with other sensory organs?
When I close my eyes, I can't feel some smells like smell of my favourite flowers, smell of forest or other things, but I never felt again smells like smell of dishes (vegetables , friuts of course) or some animals like cats. I can;t explain it
Do you agree with the theory?
For now I don't know, I don't have for now my own things about it . I must to think about it more.
Yes I have heard about it some time ago, but I can’t say that I understood it fully at the moment.
Have you watched something like this from personal experience?
Yes, I have seen some example videos.
Have you observed perceptual traps with other sensory organs?
Yes, particularly with food, for example my kind-of-vegan-but-not-really friend claims that she doesn’t like the taste of meat, but she doesn’t mind eating it when she doesn’t know that it’s in her food.
Do you agree with the theory?
Yes, I do agree
2. Yes, I can't come up with any specific examples but I definitely had similar situations before.
3. Yes, also with the eyes being involved- scientists have proven that no matter on the letter order in a word, as lnog as the frist and last lteter are crrocet our bairn wlil still relatively easily understand the message and put the letters in the correct order almost subconciously- just like you did in the sentence above.
4. I do, it seems very logical and it makes a lot of sense when I think about it.
