humans see faces in all kinds of mundane objects, but these faces aren't real — they're illusions due to a phenomenon known as face pareidolia.
Faces can be seen in all sorts of mundane objects, but these are not real – they are hallucinations caused by "utopian trompe l'oeil of human faces".
so why exactly does this happen, and how far can this distortion of reality go?
So why is this happening, and to what extent does this distortion of reality go?
humans are social animals, and reading faces is an important part of our ability to understand each other.
People are social creatures, and reading faces is an important ability that people use to understand each other.
even a glimpse of someone's face can help you determine if you've met them before, what mood they're in, and if they're paying attention to you.
Even by catching a glimpse of a person's face, you can tell if you've seen them before, their mood at the time, and whether they're paying attention to you.
we even use facial features to make snap-judgments about a person's potential trustworthiness or aggression.
We even use facial features to make quick judgments about the person's credibility and propensity for violence.
to capture all this vital information, humans h**e evolved to be very sensitive to face-like structures.
In order to capture this vital information, humans have evolved to be very sensitive to facial structure.
whenever we see something, our brain immediately starts working to identify the new visual stimuli based on our expectations and prior knowledge.
Whenever we see something, our brains immediately begin to recognise new visual stimuli, based on our expectations and prior knowledge.
and since faces are so important, humans h**e evolved several regions of the brain that enable us to identify them faster than other visual stimuli.
Since the face is so important, humans have evolved many brain regions that allow us to recognize them more quickly than other visual stimuli.
whereas recognizing most objects takes our brain around a quarter of a second, we can detect a face in just a tenth of a second.
While it takes about a quarter of a second for the brain to recognize most objects, we can recognize a face in a tenth of a second.
it makes sense that we'd prioritize identifying faces over everything else.
It is logical that we prioritize face recognition.
but brain imaging studies h**e revealed that regions may actually be too sensitive, leading them to find faces where they don't exist.
But brain imaging studies have shown that these areas may be a little too sensitive, allowing them to recognize faces out of thin air.
in one study, participants reported seeing illusory faces in over 35% of pure-noise images shown to them, despite the fact that nothing was there.
In one study, participants reported seeing faces in more than 35% of the purely random patterns provided, even though there was nothing in the images.
it might seem concerning that our brains can be so wrong so often, but these illusory faces might actually be a byproduct of something evolutionarily advantageous.
It may seem worrying that our brains often go wrong, but these imaginary faces may be the *** of evolutionary advantage
since processing all the visual input we encounter quickly and correctly is an enormous computational effort for the brain, this kind of hypersensitivity might act as a useful shortcut.
Because processing all the visual information we receive accurately and quickly is a huge burden on the brain, this hypersensitivity reaction may be the appropriate shortcut.
after all, seeing illusory faces is usually harmless, while missing a real face can lead to serious issues.
After all, the hallucination of seeing a face is usually harmless, but missing a real face can lead to serious consequences.
but for hypersensitivity to be more helpful than harmful, our brains also need to be quick at determining when a face is real and when it isn't.
But for hypersensitivity to outweigh the disadvantages, our brains need to quickly discern whether a face is real or fake.
so how fast can our brains tell when they've been duped?
So how quickly can the brain realize that it has been deceived?
to answer this question, researchers used a form of brain imaging known as magneto encephalo graphy.
To answer this question, the researchers used a brain imaging technique called encephalomagnetometer (MEG).
by measuring the magnetic fields caused by electric currents in the brain, this technique allows us to track changes in brain activity at the scale of milliseconds.
By measuring the magnetic field caused by an electric current in the brain, this technology allows us to track changes in brain activity in milliseconds.
with this tool, researchers revealed that the brain generally recognizes a face as illusory within a quarter of a second — around the same time that we can identify most non-face visual stimuli.
Using this tool, the researchers revealed that the brain typically recognizes imaginary faces in a quarter of a second, which is similar to the time it takes us to recognize non-human visual stimuli.
however, even after our brain knows the face is fake, we can still see it in the object.
However, even if our brains realize that a face is fake, we can still see it in objects.
and by messing with these brain areas, we can further impact our ability to differentiate between fact from fiction.
And if these brain regions are affected, it will be more difficult for us to distinguish between reality and illusion.
in one study, researchers stimulated a participant's fusiform face area while they were looking at a non-face object.
In one study, researchers stimulated participants' fusiform facial areas when they were non-facial objects.
as a result, the participant reported momentarily seeing facial features despite the object remaining unchanged.
As a result, the subject reported that he briefly saw some facial features, despite the fact that the object did not change in any way.
and while looking at a real face, stimulation of this same area created perceived distortions of the eyes and nose.
And when looking at an actual face, the irritation to this area creates confusion between the eyes and the nose.
these studies suggest that certain features are crucial to face detection.
These studies show that some features are extremely important for facial recognition.
just three dots can be enough to represent eyes and a mouth.
Just three dots are enough to represent the eyes and mouth.
people will even assign gender, age, and emotion to illusory faces.
People even add gender, age, and emotion to imaginary faces.
it's unclear whether a person's culture or individual history impacts these perceptions, but we do know that pareidolia isn't unique to the human experience.
We don't know exactly how a person's culture and background affect these perceptions, but we do know that "utopian trompe l'oeil" doesn't just happen in humans.
rhesus macaque monkeys show eye movements similar to our own when observing pareidolia-inducing objects and real faces, suggesting that this phenomenon is baked deep into our social primate brains.
Rhesus macaques make eye movements similar to ours when they see objects and real faces that produce "utopian trompe l'oeil" and real faces, suggesting that this phenomenon is deeply ingrained in our primate brains.
so, next time you see an unexpected face in a coffee, car, or cabinet, remember that it's just your brain working overtime not to miss the faces that really matter.
