There's a significant flaw in the study that used the coarse vs fine sugar and determined that a fine texture results in a higher perception of sweet. Since they used sugar as their source of sweetness, the finer texture is going to dissolve more easily, resulting in a stronger sweet taste, even if they have a similar mass of sugar present. Coarser sugar means less sugar contacts the taste receptors regardless of how much overall sugar is there. As it is, all they really determined is that food containing sugar delivered in a form that's easier to dissolve tastes sweeter. If they want to establish the effect of texture on taste, they really need a non-flavored method of affecting texture.
Yep, that was the one I was immediately skeptical about. They should have kept the sugar blend the same and used something else to affect texture (like wafers) if they wanted to truly test sweetness perception. I immediately thought of coarse vs fine salt
It's more about salivary amylase and transformation of sucrose (which is barely sweet, and tastes "vaguely fruity" rather than sweet) into glucose (which tastes like invert syrup). The receptor itself is more responsive to glucose. If it has a rough texture and it's not because of sugar crystals, participants will just outright HATE it. Are you kidding me? What you want is to add more sugar in the rough recipe to compensate for how poorly dissolved it is. In which case, it would strictly NOT be a matter of principle, and it would be done just because it's obviously the thing to do.
"We played holiday music and asked them to rate the taste of the food. Overwhelmingly people rated food as having had tasted better, with the exception of one group of outliers who were convinced that the food was rotten; all of whom worked retail"
One weird symptom of depression is that it can actually make your senses feel dulled. I've heard people say colors and music feel more vivid after recovering from severe depressive episodes. Personally, I've had really bad mental health days where i genuinely thought I had caught covid because the taste and smell of my food was so different. Makes sense, if mood and pleasure can affect our senses like that.
That's really interesting. I have also wondered if COVID or Long Covid were messing with me again. I can smell next to nothing right now. And I am also feeling depressed because my fiance is thousands of miles away and probably will be for a while.
I made my own comment just before which kinda relates to this, but I suffer severe sensory problems after being given psych meds for this sort of thing due to misdiagnosis of depression and a bunch of other stuff. They have altered my brain in extremely debilitating and bizarre ways. Like sound and light mixing, perceptional distortion and hallucinations, phantom pains and sensations that I can somewhat control through thought. I have lots of visual/perception issues and I see colours and lights that no one else can. Some of the distortions I have control over and I have no idea why or how. I also have control over certain autonomic processed. I had my first migraine in 2022 that sent me to ER from all this and not only did I loose vision, I experienced the visual auras and the colours in them were hyper saturated. So I have experienced what they call hyper colours where they are saturated beyond 100%. After the blindness recover, the hyper saturation for my normal vision persisted for hours.
Certain flavors are "warm" or "cold" and it has nothing to do with the temperature of the food itself. You could give me a burning hot cucumber and I'd still brain it as cold.
@@grizzlyalmighty2 it's a typo, the study is on the words "bouba" and "kiki" which are not real words, yet the majority of people associated roundness with "bouba" and sharpness with "kiki"
In high school we considered purple a flavor: it was only found in those frozen tubes of sugar water dreck. God, why did our parents let us eat all that trash?
This is cool! I'm someone who actually has synaesthesia in the traditional sense (some examples: 0:15 "Phillip" is a pink name with some gold-yellow spots/highlights; Adenosine, Thymine, Guanine, and Cytosine of DNA are red with some orange, yellow-orange with some light green, green, and light blue respectively, with the dominant colours being Red, Yellow, Green, and Blue). Synaesthesia also runs in families in my experience, my mother and I both have it (myself to a greater extent) but my dad doesn't. My mother and I are both also neurodivergent (ADHD and Asperger's/ASD), but I seem to have more symptoms/be slightly further "on the spectrum". Also, it might be a case of like attracting like but several of my friends who are also on the spectrum also experience synaesthesia of various senses. I suspect that the hyperconnected nervous systems of people with ASD and ADHD causes their brains to be "cross-wired" and process sensory information in multiple areas of the brain.
Not terribly surprised. Right up there with food tasting better in good company. We are highly social animals so all of our senses contribute to our experience of the world-- the brain being the engine that facilitates it.
My synesthesia is linguistic: I have the continuous voice dialogue going on in my head, but there's also a simultaneous music dialogue paralleling the voice. While looking at a painting, the verbal voice in my head might say "Wow, that's beautiful!", and at the same time, the non-verbal music voice might say "Da da da da dahh." This happens with any silent, read or spoken verbal sounds, meaning that I can hear the music of people, places, things, ideas, feelings, etc. If I have access to a music keyboard, I can share those musical "thoughts" with others.
Advertisers have known this for decades. Note all the slinky saxophone music in chocolate adverts. Amplified sounds of the CRUNCH in cereal adverts etc. Sounds of fat sizzling even when the food shown isn't very fatty.
A question about the taste one. wouldn't the smaller sugar grains dissolve quicker in your mouth and thus taste sweeter than the bigger rougher sugar grains?
I had a certain point in life where I was starting to associate various video games with very specific smells each for some reason; I couldn't tell you what those smells were like, and the associations slowly faded away after a while, but I can tell you for a fact it was definitely not my sweat. 😐
Imagine scraping someone scratching their nails on a chalkboard. Feel that frisson in your teeth or going down your back? There. Sound-touch synesthesia in action.
I found a relatively low dose of salvia divinorum extract gave me really intense synesthesia years ago when I was messing around. It was reliable and repeatable, but the overall experience was so unpleasant I can't imagine anybody would do it more than a couple times. It also came along with hypersensitive nipples that made wearing a shirt unbearable, intense cold sweating, and a strange awareness of my skeleton making me feel almost like a marionette puppet. It did also give sounds extremely distinctive physical sensations like hard edges, sharp corners, abrasive surfaces, and flowing waves as well as something that's almost color but not quite.
(I was young and I wanted to try experimenting with a psychedelic that was relatively non-dangerous, so I tried it at several different dosages with experiences ranging from having a 5 minute trip where I watched our reality stop existing as an out-of-sync tongue in an infinite wall of wagging tongues fell back into sync, to feeling kinda cold and uncomfortable with some synesthesia that I would say is comparable to a 2-beer buzz but cold and unpleasant)
Could also be expectations and how people select something when given an ambiguous question like pick what this scent smells like. We know candy canes are red and peppermint. We associate some things with others because people portray them like that. A gross smell is green or yellow in cartoons. Bile, sulfur and some sickly stool is similar in color. We said yes this color is stinky. It might be less synesthesia and more shared experience influencing what we pick.
As well as if there's any evidence of a causal link between certain neurotypes and synesthesia. I'm autistic and I perceive moving 3D models whenever I think of numbers, which is apparently a rarer variation.
I havent watched the full video yet, but I always thought of synesthesia as a sort of superpower: Think of a sheet of paper FILLED with very tiny 5's, everywhere just a million 5's in a tiny font. Somehwhere on that page you put a couple 2's in the same sized font. To our mundane senses it would take a long long time to scope out the hidden 2's. To someone with colour-number synesthesia, they would see a sea of red, with two very clear blue dots for example. It would be immediate, they wouldn't even have to "look" for it. Right from the very moment they looked at the page, they would already _know_ where the 2's are. Imagine how many unique scenarios and advantages could arise from the _massive_ pool of potential sensory combinations and overlap from synesthesia! There is some potential for having something like your sense of memory and sense of distance get overlapped, so that the further back a memory is, the "further away" that memory would physically feel, IIRC there have been recorded and/or reported cases of this that has been attributed to so called "total recall" or Eidetic memory. The possibilities are endless! Some musicians have tone-colour synesthesia and can perfectly remember any song from a single listen, and often times are able to actually "extrapolate" from only hearing a short clip of the music, because in their mind it forms a cohesive part of a colourful arrangement or image or some such. There's a _logic_ to the sense of colour, a sense of _knowing_ (similar to the 2's and 5's, they don't have to "think" about it) and so it's easy for them to *fairly* accurately just play the rest of the song despite having never heard that part of the song! The list goes on and on! If this intrigues you, I highly recommend looking more into synesthesia. It's magical! 😁 I whole-heartedly believe synesthesiacs are the next stage in human evolution. There's also the reality and potential of induced synesthesia! There are recorded cases of people having something like a brain trauma, or due to a disease their brain is affected in some way, or something else along those general lines, just spontaneously developing synesthesia! So in theory we may be capable of selectively inducing synesthesia medically!! There's so much potential!! -Sorry just to add one more at the end here: There's also a famous chef who has touch-taste synesthesia and he creates dishes that "feel" nice to him and they're often wild combinations of ingredients that nobody had ever tried before, but because he knew the "physical texture" was cohesive and made sense, that the dish would turn out in a favorable way. I remember hearing him describe mint as a cold glass pillar with water smoothly flowing down the entire surface, and in a weird way, I can kind of see how that would be the case! Sorry 🙇 🙏 Hahah I'm sure you can tell I'm a bit of a synesthesia fan boy, thank you for coming to my Ted Talk! 😅
Yeah sure, it's all nice when a fruit shake tastes chocolate despite having none because of the color but, then you end up with situations where I hate Carmel because it's color's flavor clashes with the actual flavor. Similarly, having too noisy (but not commiting to rainbow overload) of a color palette or too many people's voices/flavors/colors at the same time causes me to be overstimulated
Also synesthesia isn't magic. Pretty sure plenty of people without synesthesia have perfect pitch and the like. Sometimes the models we use allow us to process information more efficiently but, that shouldn't be unique to synesthesia, plenty of other people still have better information processing models than us. otherwise my sense that strategic options are a physical space would make me a grandmaster at chess and stuff but I'm sure plenty of of the pros don't share that sense but still have a more efficient model for processing potential moves Ok, rant over. It's a different experience not a better one is what I'm getting at
A superpower! :D I have synaesthesia, my visuals are generally in my mind's eye, so I don't tend to literally see 2s and 5s like how you describe, though I am very good at picking out details, and I can taste and smell things if I let myself (I tend to "block out" the extrasensory perception because it's like a deeper level of interfacing with a given stimulus, and I don't want to know more about a lot of things. I can taste and smell photographs if I let myself. My profile for example picture tastes bright, but of course the "taste" is also processed as colour for me, which is yellow-gold with pink). Just listening to a song without letting myself see/smell/taste it is very different from actually letting myself experience it, the latter can affect me very deeply. I don't listen to a lot of music because a lot of it does not benefit my health. I do think that everyone probably has ESP/synaesthesia to an extent. I can be really sensitive to the "vibe" and energy of a space, but even someone with less practice can tell when a place is creepy or when it's happy, bright, and comfortable. I'm also a musician, and I totally agree with music being colours and light (technically being a rendering/transcription of the "energy" of the piece). Probably related, playing instruments off the cuff is very easy for me and I can hear the next notes in my head and just intuitively know how the song goes. I also tend to be very creative in the kitchen and make "weird" combinations of ingredients that end up tasting awesome. It's fun to hear about other people with similar life experiences, thank you for sharing. It's very sweet that you call us the next stage of evolution but I will note that it does make existing in the modern day challenging at times... I suspect that the neurological basis for synaesthesia is a hyperconnected brain, so information is processed in a lot of places at once rather than just the regular spots (a neurological trait associated with Asperger's/ASD), meaning that I can also experience sensory overload or "shutdown" (including making speech very difficult or even very nearly impossible) if I am overstimulated or feel overwhelmed emotionally. I don't watch a lot of TV or movies because of this. Once, someone in the same room as me was watching a documentary about the Arctic or Antarctic that talked about people dying from the cold, I had to leave the room and cry and felt upset for the rest of the night. I still feel teary thinking about it. I carry earplugs with me everywhere to block out some of the stimuli of the everyday. I can't watch very fast-paced movies/TV or play very fast video games because I get overwhelmed with all of the information and I get headaches/nausea/dizziness/disorientation, and seeing people in pain or injured is extremely disturbing for me to see. I really can't stand horror, either. A world of only synaesthetes/people with more developed ESP would look very different from the one we have today. Some people probably don't get so easily overwhelmed or are able to choose to block out more information/refuse to process it on multiple "channels", but generally, people I know with synaesthesia tend to be highly sensitive.
At Heston Blumental’s restaurant they get you to crunch a carrot while listening to the sound processed and amplified. This apparently makes the carrot taste loads better.
I think I kinda have synesthesia because some voices of those person I know. I can feel the shape(or sometimes I can see it but not in my eyes) of their voices. That's why even i'm in the crowd, I can notice them immediately.
Math is blue because most things dealing with computers are blue, Science is green because it starts with the natural world which is mostly green, English or Literature is yellow because you need light to write and the sun is yellow, and History is red because much of history is written in blood which is red.
History is blue because it's dead and cold. Science is yellow because most of those experiments make me nauseous. Language is red because they are a no go for me. Math is green because that's just logical.
One sec, computers are more frequently black than blue, nature is mostly blue, since we live on a water world. Actually the CMB is most visible in every direction so science is microwave colored /jk or invisible I guess if you want to count dark energy. but it's funny how our brains convince us they're arriving at a logical conclusion when you could use near anything
I agree with Math being blue and science being green, but for me English is purple and Social Studies/History is Orange. Yellow was my Homework folder, and Red was Spanish for me.
I have a form of synethesia myself. Sensations inside my nose get translated to scents. If it's hot out, I can smell heat. Likewise with cold. And if I get bopped hard enough on the nose, the scent of pain is sharp and unmistakable. I can also _taste_ temperatures (though this might be cross-modal). It's rather annoying at times, though (for example, the taste of heat clashes _horribly_ with the taste of pepperoni, so for me pepperoni pizza is disgusting when hot, and delicious when cold).
One of the best examples I saw in a documentary was chefs being unable to correctly identify tastes of fruit/berry drinks being artificially colored. Professionals with years of experience. There is a very strong connection between sight, smell and taste in a lot of people.
No! Math is logical, so it's cool and calm, that's blue! Science is green, because it connects with nature. Language is yellow, because it can be bright and fun, but also unpleasant. History is red, because it's full of passion and blood. Arts are purple, because they're quirky, out of the box and novel. For language, those Latin languages are orange, because they connect with warm places! 😂
Philosophers in the phenomenological tradition have been making this argument for a while. Merleau-Pontie, for instance, thought it was more or less fundamental to all experience. There’s a book called “The Spell of the Sensuous” by David Abram that explores perception and ecology pretty fascinatingly
Well, nobody expects anyone to overlook anything when they're deciding how to mass-produce food. So those clickbait scientific journal articles about tactile-taste crossmodal interaction get a lot of gravity, but we need to remember that the people who are best-suited to inform others about how to improve mass-produced food have been involved in food factories for quite a while (as the owners). This is why that article has been cited 100 times: everyone is hopping on the bandwagon because they aren't sure whether different people see the same colors as each other, or if the colors are different for different people. (in retrospect, I guess we could have called our elementary school teacher's little "paradox" about "not being able to know" what colors look like to others an ancient anti-Mendelian roar) It doesn't really matter what kind of topical nonsense a scientist is going to force everyone to watch about food. He's certainly never experimented with food in his own home. He's just trying to walk away thinking he's "won" in his solo fight against "greedy people" (or, to be more accurate, "his solo attempt to clean up after regrettable lapses in judgement on behalf of appellate court judges and other such influential people"). Not that anyone ever minded if he were to win. His feelings are just kind of "a tree falling in the forest with no one to hear it", in the end. What was the point of insisting on being critical THAT MUCH? There was no point at all. How can we reach that kid, and make sure he knows what witness protection programs are? How can we tell him that the invention and universal spread of the spoken word was a revolution against an indistinct "absolute monarchy" which it appears that other animals have continued to be governed under, so that the community of the future would be able to hold trials and appeals rather than for the "monarch" to be relied on for more things than he'd ever end up doing, and then it would be possible to become devoted to furthering the field of medicine? Would HE say that perhaps before the first spoken word, the other animals ALSO had a completely different type of community structure? How can we document all of his stances on everything? Should we start off by forcing him to become a forensic scientist?
We’re also labeled a billion things by strangers every day. If you're energetic some thing you're manic, or just happy, or labeled crazy. So thank you. Everyone kinda has a form of everything! It’s cool 😎
Knowing the reference, here is a real response... it does. Red sports cars have higher insurance premiums and are more likely to be involved in traffic violations. Red go fast.
I've always suspected I have a very mild form of synesthesia due to my brain automatically assigning very specific colours to every letter in the alphabet and every numerical digit. When I was a kid I'd often use coloured pencils to write letters and numbers in the colours that seemed natural to them. (The letter M is a crimson red for example, N is orange, P is a pale tan, O is dark navy blue, etc.) However since this doesn't seem to extend to anything else in my daily life to the point that I often don't even think about it until someone mentions synesthesia, I have to wonder if it even really counts as true synesthesia at all. All my math books were blue, grey or black, by the way. Science was either blue or green (if Math was blue, science was green, but if math was black or grey that year, science was blue.) Red I always reserved for English, and history was a very dark pine green or brown. I don't recall ever having many yellow notebooks.
Interesting at 6:45 For all my life, whenever I wanted to take in a taste very intensely or concentrate on it, I have been closing my eyes and sometimes even asking people around me to stop talking for a moment, so I can taste better. And it works for me. Now, did that knowledge tell me any earlier than while watching that video, that this may be a VERY good reason not to watch videos while eating for 1) I may enjoy my meals way more when not bombarded with lots of other sensory input at the same time and 2) maybe I would even have an easier time to losing weight (which my health desperately demands) since I may enjoy smaller portions without sensory overload more than my now bigger portions with sensory overload? Embarrassingly, I only now realised that. Will try that out. Thanks, SciShow!
Bonus fact: I also close my eyes when I want to hear better or experience touch, like a massage or cuddling, more strongly and it feels like it works as well. As if freeing some RAM on my system allows the remaining senses to use more of it.
8:00 Like cozy on the white eggshell coloured couch where you just spilled black coffee all over...had a bad time cleaning it up and finally get to have your Panettone in piece 😊😅
6 or so graphic design students working on assignments in college. Student no 1 ...What colour is 3? The rest gave suggestions varying around yellows, yellowy greens and greeny yellows. A minute later one pointed out that no one had questioned the concept that numbers had colours. Years later when I, at least, linked this with synesthesia and reslised that it was probably more common that we had been led to believe.
Some things I watch have flavors. They're not necessarily a food flavor but they're a flavor. If they're a really delicious flavor, my mouth will water and I will want more; but it's almost impossible to find something else with the same or similar flavor. So I end up watching the same thing over and over and over until I can escape the desire to 'consume' that flavor. I don't know if it's a kind of synesthesia, but I am AuDHD so my brain does things. I did go to uni with a "common" type synethetic. She saw sounds as colors and made some really beautiful paintings.
I have ASD and ADHD as well, and I (as well as my mother) am also a synaesthete. My theory is that the hyperconnected brains of people with ASD and ADHD causes information to be processed in multiple areas of the brain that they "normally" wouldn't, causing additional sensory experiences to be "output" from the same information. And yes, what you describe is a form of synaesthesia. If an input creates an additional output that it "should" not directly cause, it's synaesthesia. Someone I know who is also synaesthetic also tastes things.
I have a hypothesis that our color-subject associations are actually products of common trends in textbook cover design. Science textbooks are overwhelmingly green; English textbooks are often yellow or another bright color. My math textbooks were blue and so were the notebooks.
When I listened to a certain CD I hadn't listened to for like 15 years, I suddenly smelled tatami mat smell that is getting warmed up by the summer sun. Fun fact: There was no tatami mat within several hundreds metres.
"Warmer" tones or lower frequency sound is redder while higher pitched "cooler" sounds are bluer. Sounds nearer the peak frequencies you can hear might be associated with green, yellow, or white.
3) I would think the flute vs violin could still be an example of distracting noise, just like the white noise study. Would you not have heightened brain activity and more disruptive sleep from sudden and inconsistent music vs smooth transitional music? 4) Wouldn’t the 2-phenylethanol vs 1-butanol be an example of how our emotions effect our sensory perceptions rather than a correlation of sound inputs?
hmm One time I saw and tasted a Purple cloud floating across my living room. Thanks to jimi hendrix "Purple Haze" & 6 hits of LSD . Pretty sure that using loudspeakers that I'd literally blown screens out of windows with before, had something to do with it because I've taken twice that without seeing and tasting sounds. On that occasion I lived in a trailer park so I had to be lowkey invisible and used headphones only. I did have my speaker volume knob marked with whiteout at max acceptable levels but I was afraid I wouldn't be able to see it while peaking, and I always partied late at night. My favorite was stargazing from the highest point in town (eliminating light pollution). Living where your closest neighbor is 1/2 mile away has it's advantages. I told a former roommate (cop) where I was renting and he said "we don't go out there unless it's a report of shots fired" LOL. Ironically enough I was awakened several times by the sound of machine gunfire. I always assumed it was some (Army) Rangers blowing off , I was too poor to own a phone , besides calling the cops for anything is just against my DNA.

My guess is that the bottom line is mood. All the pleasant stimuli make it better. The negative stimuli make it worse. It's called complex compound-perceptive experience. Or at least that's what I call it.
How do we know if it's synesthesia or just pattern matching from past experiences? For example, higher frequency in dry hands and maybe you also met your first Danny who smelled like oranges. So now you associate Danny with any citrusy smell
Thank you for stating that there is a difference between this "mild" and diagnosed synesthesia. However I would argue that most of these tests do not prove synesthesia or even something similar within a small margin but rather simply association through possibly taught behaviors because there are too many unmentioned variables that would alter results. With that said as someone who has synesthesia most of these things aren't remotely like synesthesia. Synesthesia is way more complex and often can overstimulated the individual to the point of sickness.
I believe cross model applies when I am eating and someone else is smoking in or around my apt and it seeps into my home. You can taste the smoke of the cigarette, cigar or marijuana. It makes the taste of my food/drink enjoyable.
Black metal is black, powermetal is yellow, gothic metal is purple, thrash metal is orange, doom metal is red or purple, symphonic metal is blue or white, folk metal is green, metalcore is rainbow, alternative metal can be any color
What an irony to see a commercial plug about a product that is supposed to smell good with a name of a god of death and embalming in a video that (partially) delves into the fact that your knowledge might inform your senses.
I have sound to color synesthesia and up until a few years ago, I thought this was normal. I see music and loud sounds as certain colors and organize music playlists according to the colors I see. And I often wondered that if I were to lose my hearing if my colors would be dulled.
The rough sugar treat might literally have been less sweet/ more sour because the sugar isn’t fully dissolved? Just spitballin’ here. Or was it only rough on the outside like a lemon drop?
Is being able to detect an exact taste and taste it in your mouth, by just seeing it, an example? See a picture, and by rubbing your fingers together, you can feel the texture of the picture, say like a fabric or yarn and perceive how much flounce there is?
There's another example of how we all have synesthesia that I'm surprised wasn't mentioned. It's something I've been saying for years. It's the ability to feel emotions through patterns and pitch in in sound. Tell me, how exactly would you explain what exactly music is to an alien race?
~4:44 how would the availability to sensory perception be effected by the structure of the glucose? eg, do bigger molecules disolve into the solution that the gustatory neurons react with in the same quantities, and is there a timeframe that's perceptible? Soz for nerding out on yous

When I once touched a quickly vibrating bottle I realised I know what sound it made. It was so silent I didn't hear it so I think it's because I touched it and felt the vibration with my hands
Math is red, english is blue, green is science might have to do with the color of the notebooks in the country. In Hungary mathbooks (books with squares), are mostly colored red, books with lines are mostly colored blue. Science may be tricky, because the green books are usually blank. But a lot of wcience teachers requested blanks so we could draw better in them. When we did geometry we were also asked to use blanks(green) instead of the usual red(squares). So maybe some of these perceptions comes from these.
I've never seen a consistent system like that in the US. Usually every kind of notebook is available in a selection of colors, which is why people form such strong individual preferences.
As a side note, "we all have X" is one of the most insulting things you can say to someone who has a troublesome diagnosis/condition. I've had *clinicians* say "well, don't we all have a little PTSD" in response to my mention of the PTSD I had from a 3-year traumatic and violent experience.
I'd also argue most are just measuring our mood's impact on our enjoyment of things, or the lenses we view the world through (positive/ negative, pleasant/apathetic/off-putting). ...not a crossover of sense experience.
I have mirror touch. I can feel what it feels like when I touch people or animals. It's really weird and has changed my life. I can also feel the sensations my touches produce so things like fighting with my older half brothers (twins three years older) when we were kids was painful even when we got older & I got bigger than them and I started winning. Punching someone is almost counter-productive. If there is something between my skin and theirs, the sensations I feel are diminished through a t-shirt and touching someone with say, a stick produces none. It has helped in my love life, so it's mainly a good thing!
Science is blue. Math is black. English is green. History is blue, but it's like a cornflower blue (science is cobalt). Piano music is another blue, a deep navy. Piano music is also cool, humid, and windless. Guitar music is drier and warmer. Violin music is hot and humid with a breeze. It's also very red. It's the reddest instrument. Banjo music is yellow, and it's a springy post-rain warm. Organ music is dank and damp and purple. It's a bit umami-ish too. Brass instruments are like rich sweet coffee drinks. But they're not brown, they're green. The sound of traffic on a big highway is crunchy and vinegary, but traffic on a city street is sweeter and chewier. This video is a peachy orange and smells like toasted pecans.
This strikes me the same way as when allistic people say stupid things like "everyone's a little bit autistic". No. No, they're not, and not everyone is a "little bit synaesthetic", nor is someone who feels queasy in the morning and puts on a little weight a "little bit pregnant" in the absence of a fetus.
I think of loads of people/smells/words as shapes. I actually think most of my thoughts are images and shapes, none of those shapes being words in any meaningful order. I have realized as I've grown older that I need to say a lot out loud in order to process the nonsense that's going on in my head
Is it crossmodal interaction when I can’t hear as well without my glasses? I theorise that my brain needs to focus on sight and therefore gives less attention to sound.
I Def do Not have the colour and sound overlap at all. The “these subjects are these colours” confuses me. They… don’t align with any colours? They’re subjects. But sound and Touch/sensation? Yes. Yes. Which is why anybody who open mouth ears around me will never see me during meals again.
I don't have synesthesia but I associate the concepts (not the typographical words themselves) of math with blue and English with green. I might associate P.E. with orange and maybe history with red. (Interestingly history is one of my favorite subjects and I don't particularly like red.) Science feels like too broad a category so if I wanted to try and associate colors I'd probably break it down into individual disciplines (biology, physics, etc.).
There's a significant flaw in the study that used the coarse vs fine sugar and determined that a fine texture results in a higher perception of sweet. Since they used sugar as their source of sweetness, the finer texture is going to dissolve more easily, resulting in a stronger sweet taste, even if they have a similar mass of sugar present. Coarser sugar means less sugar contacts the taste receptors regardless of how much overall sugar is there. As it is, all they really determined is that food containing sugar delivered in a form that's easier to dissolve tastes sweeter. If they want to establish the effect of texture on taste, they really need a non-flavored method of affecting texture.
Just add some microplastics 😋
I was thinking about that while the texture experiment was being talked about.
Came looking for that- glad it's the first comment at the moment. I'd think they could use something else to make it grainy
Yep, that was the one I was immediately skeptical about. They should have kept the sugar blend the same and used something else to affect texture (like wafers) if they wanted to truly test sweetness perception. I immediately thought of coarse vs fine salt
It's more about salivary amylase and transformation of sucrose (which is barely sweet, and tastes "vaguely fruity" rather than sweet) into glucose (which tastes like invert syrup). The receptor itself is more responsive to glucose. If it has a rough texture and it's not because of sugar crystals, participants will just outright HATE it. Are you kidding me? What you want is to add more sugar in the rough recipe to compensate for how poorly dissolved it is. In which case, it would strictly NOT be a matter of principle, and it would be done just because it's obviously the thing to do.
"We played holiday music and asked them to rate the taste of the food. Overwhelmingly people rated food as having had tasted better, with the exception of one group of outliers who were convinced that the food was rotten; all of whom worked retail"
One weird symptom of depression is that it can actually make your senses feel dulled. I've heard people say colors and music feel more vivid after recovering from severe depressive episodes. Personally, I've had really bad mental health days where i genuinely thought I had caught covid because the taste and smell of my food was so different. Makes sense, if mood and pleasure can affect our senses like that.
That's really interesting. I have also wondered if COVID or Long Covid were messing with me again. I can smell next to nothing right now. And I am also feeling depressed because my fiance is thousands of miles away and probably will be for a while.
I made my own comment just before which kinda relates to this, but I suffer severe sensory problems after being given psych meds for this sort of thing due to misdiagnosis of depression and a bunch of other stuff. They have altered my brain in extremely debilitating and bizarre ways. Like sound and light mixing, perceptional distortion and hallucinations, phantom pains and sensations that I can somewhat control through thought.
I have lots of visual/perception issues and I see colours and lights that no one else can. Some of the distortions I have control over and I have no idea why or how. I also have control over certain autonomic processed.
I had my first migraine in 2022 that sent me to ER from all this and not only did I loose vision, I experienced the visual auras and the colours in them were hyper saturated. So I have experienced what they call hyper colours where they are saturated beyond 100%. After the blindness recover, the hyper saturation for my normal vision persisted for hours.
anhedonia like stuff yea
Certain flavors are "warm" or "cold" and it has nothing to do with the temperature of the food itself. You could give me a burning hot cucumber and I'd still brain it as cold.
Makes sense how humans came up with the four humors system like this, which labels pretty much every food as inherently hot or cold and dry or wet.
“Brain it” love it

I remember Purple Heinz ketchup. People couldn't adjust the color VS flavor and it tanked.
In high school we considered purple a flavor: it was only found in those frozen tubes of sugar water dreck.

This is cool! I'm someone who actually has synaesthesia in the traditional sense (some examples: 0:15 "Phillip" is a pink name with some gold-yellow spots/highlights; Adenosine, Thymine, Guanine, and Cytosine of DNA are red with some orange, yellow-orange with some light green, green, and light blue respectively, with the dominant colours being Red, Yellow, Green, and Blue). Synaesthesia also runs in families in my experience, my mother and I both have it (myself to a greater extent) but my dad doesn't. My mother and I are both also neurodivergent (ADHD and Asperger's/ASD), but I seem to have more symptoms/be slightly further "on the spectrum". Also, it might be a case of like attracting like but several of my friends who are also on the spectrum also experience synaesthesia of various senses. I suspect that the hyperconnected nervous systems of people with ASD and ADHD causes their brains to be "cross-wired" and process sensory information in multiple areas of the brain.
Not terribly surprised. Right up there with food tasting better in good company. We are highly social animals so all of our senses contribute to our experience of the world-- the brain being the engine that facilitates it.
My synesthesia is linguistic: I have the continuous voice dialogue going on in my head, but there's also a simultaneous music dialogue paralleling the voice. While looking at a painting, the verbal voice in my head might say "Wow, that's beautiful!", and at the same time, the non-verbal music voice might say "Da da da da dahh." This happens with any silent, read or spoken verbal sounds, meaning that I can hear the music of people, places, things, ideas, feelings, etc. If I have access to a music keyboard, I can share those musical "thoughts" with others.
This is awesome, I'd love to hear your music.
Shout out to the stock video guy at 6:40 cutting a ciabatta sandwich with a butter knife and fork
Advertisers have known this for decades. Note all the slinky saxophone music in chocolate adverts. Amplified sounds of the CRUNCH in cereal adverts etc. Sounds of fat sizzling even when the food shown isn't very fatty.
A question about the taste one. wouldn't the smaller sugar grains dissolve quicker in your mouth and thus taste sweeter than the bigger rougher sugar grains?
Yes, there's a popular comment here where several people see it this way.
I had a certain point in life where I was starting to associate various video games with very specific smells each for some reason; I couldn't tell you what those smells were like, and the associations slowly faded away after a while, but I can tell you for a fact it was definitely not my sweat. 😐
'Sonic Seasonings' was a great ambient music album by Wendy Carlos. She and Warner Bros should sue for copyright.
Imagine scraping someone scratching their nails on a chalkboard. Feel that frisson in your teeth or going down your back? There. Sound-touch synesthesia in action.
I found a relatively low dose of salvia divinorum extract gave me really intense synesthesia years ago when I was messing around. It was reliable and repeatable, but the overall experience was so unpleasant I can't imagine anybody would do it more than a couple times. It also came along with hypersensitive nipples that made wearing a shirt unbearable, intense cold sweating, and a strange awareness of my skeleton making me feel almost like a marionette puppet. It did also give sounds extremely distinctive physical sensations like hard edges, sharp corners, abrasive surfaces, and flowing waves as well as something that's almost color but not quite.
(I was young and I wanted to try experimenting with a psychedelic that was relatively non-dangerous, so I tried it at several different dosages with experiences ranging from having a 5 minute trip where I watched our reality stop existing as an out-of-sync tongue in an infinite wall of wagging tongues fell back into sync, to feeling kinda cold and uncomfortable with some synesthesia that I would say is comparable to a 2-beer buzz but cold and unpleasant)
That sounds like my experiences with LSD. The worst time was when I puked on it, because I was so hyper aware of every sensation in my body.
Could also be expectations and how people select something when given an ambiguous question like pick what this scent smells like. We know candy canes are red and peppermint. We associate some things with others because people portray them like that. A gross smell is green or yellow in cartoons. Bile, sulfur and some sickly stool is similar in color. We said yes this color is stinky. It might be less synesthesia and more shared experience influencing what we pick.
Wendy Carlos released an electronic music album named “Sonic Seasonings” back in the 1970’s
I'd be interested to see a study of how autism might affect the taste of different textured foods
Ps. English is blue
As well as if there's any evidence of a causal link between certain neurotypes and synesthesia. I'm autistic and I perceive moving 3D models whenever I think of numbers, which is apparently a rarer variation.
english is 100% blue
I havent watched the full video yet, but I always thought of synesthesia as a sort of superpower:
Think of a sheet of paper FILLED with very tiny 5's, everywhere just a million 5's in a tiny font. Somehwhere on that page you put a couple 2's in the same sized font. To our mundane senses it would take a long long time to scope out the hidden 2's. To someone with colour-number synesthesia, they would see a sea of red, with two very clear blue dots for example. It would be immediate, they wouldn't even have to "look" for it. Right from the very moment they looked at the page, they would already _know_ where the 2's are.
Imagine how many unique scenarios and advantages could arise from the _massive_ pool of potential sensory combinations and overlap from synesthesia!
There is some potential for having something like your sense of memory and sense of distance get overlapped, so that the further back a memory is, the "further away" that memory would physically feel, IIRC there have been recorded and/or reported cases of this that has been attributed to so called "total recall" or Eidetic memory.
The possibilities are endless! Some musicians have tone-colour synesthesia and can perfectly remember any song from a single listen, and often times are able to actually "extrapolate" from only hearing a short clip of the music, because in their mind it forms a cohesive part of a colourful arrangement or image or some such. There's a _logic_ to the sense of colour, a sense of _knowing_ (similar to the 2's and 5's, they don't have to "think" about it) and so it's easy for them to *fairly* accurately just play the rest of the song despite having never heard that part of the song!
The list goes on and on! If this intrigues you, I highly recommend looking more into synesthesia. It's magical! 😁 I whole-heartedly believe synesthesiacs are the next stage in human evolution.
There's also the reality and potential of induced synesthesia! There are recorded cases of people having something like a brain trauma, or due to a disease their brain is affected in some way, or something else along those general lines, just spontaneously developing synesthesia! So in theory we may be capable of selectively inducing synesthesia medically!! There's so much potential!!
-Sorry just to add one more at the end here: There's also a famous chef who has touch-taste synesthesia and he creates dishes that "feel" nice to him and they're often wild combinations of ingredients that nobody had ever tried before, but because he knew the "physical texture" was cohesive and made sense, that the dish would turn out in a favorable way. I remember hearing him describe mint as a cold glass pillar with water smoothly flowing down the entire surface, and in a weird way, I can kind of see how that would be the case!
Sorry 🙇 🙏 Hahah I'm sure you can tell I'm a bit of a synesthesia fan boy, thank you for coming to my Ted Talk! 😅
Yeah sure, it's all nice when a fruit shake tastes chocolate despite having none because of the color but, then you end up with situations where I hate Carmel because it's color's flavor clashes with the actual flavor.
Similarly, having too noisy (but not commiting to rainbow overload) of a color palette or too many people's voices/flavors/colors at the same time causes me to be overstimulated
Also synesthesia isn't magic. Pretty sure plenty of people without synesthesia have perfect pitch and the like. Sometimes the models we use allow us to process information more efficiently but, that shouldn't be unique to synesthesia, plenty of other people still have better information processing models than us. otherwise my sense that strategic options are a physical space would make me a grandmaster at chess and stuff but I'm sure plenty of of the pros don't share that sense but still have a more efficient model for processing potential moves
Ok, rant over. It's a different experience not a better one is what I'm getting at
A superpower! :D I have synaesthesia, my visuals are generally in my mind's eye, so I don't tend to literally see 2s and 5s like how you describe, though I am very good at picking out details, and I can taste and smell things if I let myself (I tend to "block out" the extrasensory perception because it's like a deeper level of interfacing with a given stimulus, and I don't want to know more about a lot of things. I can taste and smell photographs if I let myself. My profile for example picture tastes bright, but of course the "taste" is also processed as colour for me, which is yellow-gold with pink). Just listening to a song without letting myself see/smell/taste it is very different from actually letting myself experience it, the latter can affect me very deeply. I don't listen to a lot of music because a lot of it does not benefit my health. I do think that everyone probably has ESP/synaesthesia to an extent. I can be really sensitive to the "vibe" and energy of a space, but even someone with less practice can tell when a place is creepy or when it's happy, bright, and comfortable.
I'm also a musician, and I totally agree with music being colours and light (technically being a rendering/transcription of the "energy" of the piece). Probably related, playing instruments off the cuff is very easy for me and I can hear the next notes in my head and just intuitively know how the song goes. I also tend to be very creative in the kitchen and make "weird" combinations of ingredients that end up tasting awesome. It's fun to hear about other people with similar life experiences, thank you for sharing.
It's very sweet that you call us the next stage of evolution but I will note that it does make existing in the modern day challenging at times... I suspect that the neurological basis for synaesthesia is a hyperconnected brain, so information is processed in a lot of places at once rather than just the regular spots (a neurological trait associated with Asperger's/ASD), meaning that I can also experience sensory overload or "shutdown" (including making speech very difficult or even very nearly impossible) if I am overstimulated or feel overwhelmed emotionally. I don't watch a lot of TV or movies because of this. Once, someone in the same room as me was watching a documentary about the Arctic or Antarctic that talked about people dying from the cold, I had to leave the room and cry and felt upset for the rest of the night. I still feel teary thinking about it. I carry earplugs with me everywhere to block out some of the stimuli of the everyday. I can't watch very fast-paced movies/TV or play very fast video games because I get overwhelmed with all of the information and I get headaches/nausea/dizziness/disorientation, and seeing people in pain or injured is extremely disturbing for me to see. I really can't stand horror, either. A world of only synaesthetes/people with more developed ESP would look very different from the one we have today. Some people probably don't get so easily overwhelmed or are able to choose to block out more information/refuse to process it on multiple "channels", but generally, people I know with synaesthesia tend to be highly sensitive.
At Heston Blumental’s restaurant they get you to crunch a carrot while listening to the sound processed and amplified. This apparently makes the carrot taste loads better.
3:54 Yes, many people with sensory sensitivities are already highly aware of this fact lol
Did they control for the fact that less sugar will dissolve so you can taste it if the sugar is more coarse? Seems questionable at a glance.
I think I kinda have synesthesia because some voices of those person I know. I can feel the shape(or sometimes I can see it but not in my eyes) of their voices. That's why even i'm in the crowd, I can notice them immediately.
Math is blue because most things dealing with computers are blue, Science is green because it starts with the natural world which is mostly green, English or Literature is yellow because you need light to write and the sun is yellow, and History is red because much of history is written in blood which is red.
Exactly 🎉
Correct. All other modalities are objectively wrong.
History is blue because it's dead and cold. Science is yellow because most of those experiments make me nauseous. Language is red because they are a no go for me. Math is green because that's just logical.
One sec, computers are more frequently black than blue, nature is mostly blue, since we live on a water world. Actually the CMB is most visible in every direction so science is microwave colored /jk or invisible I guess if you want to count dark energy. but it's funny how our brains convince us they're arriving at a logical conclusion when you could use near anything
3:56 ContraPoints ruined the word "mouthfeel" for me
😂
Math is blue, English is red, science is green, history is yellow. I’m sure it relates to the color your textbooks were most often in school.
Math red, English blue for me.
I used blue for history, yellow for math
my math and science is the same as yours but English and history are the other way round for me.
This is the only right answer
I agree with Math being blue and science being green, but for me English is purple and Social Studies/History is Orange.
Yellow was my Homework folder, and Red was Spanish for me.
I have a form of synethesia myself.
Sensations inside my nose get translated to scents. If it's hot out, I can smell heat. Likewise with cold. And if I get bopped hard enough on the nose, the scent of pain is sharp and unmistakable.
I can also _taste_ temperatures (though this might be cross-modal).
It's rather annoying at times, though (for example, the taste of heat clashes _horribly_ with the taste of pepperoni, so for me pepperoni pizza is disgusting when hot, and delicious when cold).
Americans have Synesthesia, the rest of the English speaking world has Synaesthesia.
Sounds about right.
Recently learned about the Bouba Kiki effect from xkcd so I’m excited to watch this one!
One of the best examples I saw in a documentary was chefs being unable to correctly identify tastes of fruit/berry drinks being artificially colored. Professionals with years of experience. There is a very strong connection between sight, smell and taste in a lot of people.
I really enjoyed this episode. Thank you.
No!
Math is logical, so it's cool and calm, that's blue!
Science is green, because it connects with nature.
Language is yellow, because it can be bright and fun, but also unpleasant.
History is red, because it's full of passion and blood.
Arts are purple, because they're quirky, out of the box and novel.
For language, those Latin languages are orange, because they connect with warm places! 😂
Gonna have to try that soothing music trick with morning coffee.
Philosophers in the phenomenological tradition have been making this argument for a while. Merleau-Pontie, for instance, thought it was more or less fundamental to all experience. There’s a book called “The Spell of the Sensuous” by David Abram that explores perception and ecology pretty fascinatingly
Well, nobody expects anyone to overlook anything when they're deciding how to mass-produce food. So those clickbait scientific journal articles about tactile-taste crossmodal interaction get a lot of gravity, but we need to remember that the people who are best-suited to inform others about how to improve mass-produced food have been involved in food factories for quite a while (as the owners). This is why that article has been cited 100 times: everyone is hopping on the bandwagon because they aren't sure whether different people see the same colors as each other, or if the colors are different for different people. (in retrospect, I guess we could have called our elementary school teacher's little "paradox" about "not being able to know" what colors look like to others an ancient anti-Mendelian roar)
It doesn't really matter what kind of topical nonsense a scientist is going to force everyone to watch about food. He's certainly never experimented with food in his own home. He's just trying to walk away thinking he's "won" in his solo fight against "greedy people" (or, to be more accurate, "his solo attempt to clean up after regrettable lapses in judgement on behalf of appellate court judges and other such influential people"). Not that anyone ever minded if he were to win. His feelings are just kind of "a tree falling in the forest with no one to hear it", in the end. What was the point of insisting on being critical THAT MUCH? There was no point at all.
How can we reach that kid, and make sure he knows what witness protection programs are? How can we tell him that the invention and universal spread of the spoken word was a revolution against an indistinct "absolute monarchy" which it appears that other animals have continued to be governed under, so that the community of the future would be able to hold trials and appeals rather than for the "monarch" to be relied on for more things than he'd ever end up doing, and then it would be possible to become devoted to furthering the field of medicine?
Would HE say that perhaps before the first spoken word, the other animals ALSO had a completely different type of community structure?
How can we document all of his stances on everything?
Should we start off by forcing him to become a forensic scientist?
We’re also labeled a billion things by strangers every day. If you're energetic some thing you're manic, or just happy, or labeled crazy. So thank you. Everyone kinda has a form of everything! It’s cool 😎

I've always suspected I have a very mild form of synesthesia due to my brain automatically assigning very specific colours to every letter in the alphabet and every numerical digit. When I was a kid I'd often use coloured pencils to write letters and numbers in the colours that seemed natural to them. (The letter M is a crimson red for example, N is orange, P is a pale tan, O is dark navy blue, etc.) However since this doesn't seem to extend to anything else in my daily life to the point that I often don't even think about it until someone mentions synesthesia, I have to wonder if it even really counts as true synesthesia at all.
All my math books were blue, grey or black, by the way. Science was either blue or green (if Math was blue, science was green, but if math was black or grey that year, science was blue.) Red I always reserved for English, and history was a very dark pine green or brown. I don't recall ever having many yellow notebooks.
Interesting at 6:45
For all my life, whenever I wanted to take in a taste very intensely or concentrate on it, I have been closing my eyes and sometimes even asking people around me to stop talking for a moment, so I can taste better. And it works for me. Now, did that knowledge tell me any earlier than while watching that video, that this may be a VERY good reason not to watch videos while eating for 1) I may enjoy my meals way more when not bombarded with lots of other sensory input at the same time and 2) maybe I would even have an easier time to losing weight (which my health desperately demands) since I may enjoy smaller portions without sensory overload more than my now bigger portions with sensory overload?
Embarrassingly, I only now realised that.
Will try that out. Thanks, SciShow!
Bonus fact: I also close my eyes when I want to hear better or experience touch, like a massage or cuddling, more strongly and it feels like it works as well. As if freeing some RAM on my system allows the remaining senses to use more of it.

6 or so graphic design students working on assignments in college.
Student no 1 ...What colour is 3?
The rest gave suggestions varying around yellows, yellowy greens and greeny yellows.
A minute later one pointed out that no one had questioned the concept that numbers had colours.
Years later when I, at least, linked this with synesthesia and reslised that it was probably more common that we had been led to believe.
Some things I watch have flavors. They're not necessarily a food flavor but they're a flavor. If they're a really delicious flavor, my mouth will water and I will want more; but it's almost impossible to find something else with the same or similar flavor. So I end up watching the same thing over and over and over until I can escape the desire to 'consume' that flavor. I don't know if it's a kind of synesthesia, but I am AuDHD so my brain does things.
I did go to uni with a "common" type synethetic. She saw sounds as colors and made some really beautiful paintings.
I have ASD and ADHD as well, and I (as well as my mother) am also a synaesthete. My theory is that the hyperconnected brains of people with ASD and ADHD causes information to be processed in multiple areas of the brain that they "normally" wouldn't, causing additional sensory experiences to be "output" from the same information. And yes, what you describe is a form of synaesthesia. If an input creates an additional output that it "should" not directly cause, it's synaesthesia. Someone I know who is also synaesthetic also tastes things.
I have a hypothesis that our color-subject associations are actually products of common trends in textbook cover design. Science textbooks are overwhelmingly green; English textbooks are often yellow or another bright color. My math textbooks were blue and so were the notebooks.
When I listened to a certain CD I hadn't listened to for like 15 years, I suddenly smelled tatami mat smell that is getting warmed up by the summer sun. Fun fact: There was no tatami mat within several hundreds metres.
"Warmer" tones or lower frequency sound is redder while higher pitched "cooler" sounds are bluer. Sounds nearer the peak frequencies you can hear might be associated with green, yellow, or white.
3:15 Shai-Hulud?
3) I would think the flute vs violin could still be an example of distracting noise, just like the white noise study. Would you not have heightened brain activity and more disruptive sleep from sudden and inconsistent music vs smooth transitional music?
4) Wouldn’t the 2-phenylethanol vs 1-butanol be an example of how our emotions effect our sensory perceptions rather than a correlation of sound inputs?
wait you didnt split science into physics (yellow), chemistry (red) and biology (green)
(and maths is blue and english is yellow)
Touch and hearing are related because sound transmission needs a medium to generate vibrations (sound waves). This is especially true with LFE.
There's no way those rose-tinted glasses weren't there on purpose haha. I love this channel so much. Merry Christmas.

Thanks to jimi hendrix "Purple Haze" & 6 hits of LSD .
Pretty sure that using loudspeakers that I'd literally blown screens out of windows with before, had something to do with it because I've taken twice that without seeing and tasting sounds.
On that occasion I lived in a trailer park so I had to be lowkey invisible and used headphones only.
I did have my speaker volume knob marked with whiteout at max acceptable levels but I was afraid I wouldn't be able to see it while peaking, and I always partied late at night. My favorite was stargazing from the highest point in town (eliminating light pollution).
Living where your closest neighbor is 1/2 mile away has it's advantages. I told a former roommate (cop) where I was renting and he said "we don't go out there unless it's a report of shots fired" LOL.
Ironically enough I was awakened several times by the sound of machine gunfire. I always assumed it was some (Army) Rangers blowing off , I was too poor to own a phone , besides calling the cops for anything is just against my DNA.

How can we tell him that the invention and universal spread of the spoken word was a revolution against an indistinct "absolute monarchy" which it appears that other animals have continued to be governed under, so that the community of the future would be able to hold trials and appeals rather than for the "monarch" to be relied on for more things than he'd ever end up doing, and then it would be possible to become devoted to furthering the field of medicine?
Would HE say that perhaps before the first spoken word, the other animals ALSO had a completely different type of community structure?
How can we document all of his stances on everything?
Should we start off by forcing him to become a forensic scientist?
My guess is that the bottom line is mood. All the pleasant stimuli make it better. The negative stimuli make it worse. It's called complex compound-perceptive experience. Or at least that's what I call it.
For me math was blue, english blue, science blue, history blue..... they were all blue. I really like blue 💙
Dabba dee, dabba di?
How do we know if it's synesthesia or just pattern matching from past experiences? For example, higher frequency in dry hands and maybe you also met your first Danny who smelled like oranges. So now you associate Danny with any citrusy smell
I hear bright colours. Stained glass windows are a whole other experience :)
Thank you for stating that there is a difference between this "mild" and diagnosed synesthesia. However I would argue that most of these tests do not prove synesthesia or even something similar within a small margin but rather simply association through possibly taught behaviors because there are too many unmentioned variables that would alter results. With that said as someone who has synesthesia most of these things aren't remotely like synesthesia. Synesthesia is way more complex and often can overstimulated the individual to the point of sickness.
I believe cross model applies when I am eating and someone else is smoking in or around my apt and it seeps into my home. You can taste the smoke of the cigarette, cigar or marijuana. It makes the taste of my food/drink enjoyable.
Black metal is black, powermetal is yellow, gothic metal is purple, thrash metal is orange, doom metal is red or purple, symphonic metal is blue or white, folk metal is green, metalcore is rainbow, alternative metal can be any color
What color is Tool?
What an irony to see a commercial plug about a product that is supposed to smell good with a name of a god of death and embalming in a video that (partially) delves into the fact that your knowledge might inform your senses.
Science is blue
That's why my favorite day is Tuesday - it tastes like blue raspberry!
I have sound to color synesthesia and up until a few years ago, I thought this was normal. I see music and loud sounds as certain colors and organize music playlists according to the colors I see. And I often wondered that if I were to lose my hearing if my colors would be dulled.
A last minute christmas gift from scishow for those of us who didn’t get much from anybody in our family (aka most moms)? I’ll take it, thank you!
The rough sugar treat might literally have been less sweet/ more sour because the sugar isn’t fully dissolved? Just spitballin’ here. Or was it only rough on the outside like a lemon drop?
Is being able to detect an exact taste and taste it in your mouth, by just seeing it, an example? See a picture, and by rubbing your fingers together, you can feel the texture of the picture, say like a fabric or yarn and perceive how much flounce there is?
What about that thing where I'm looking for a parking space and I have to turn down the radio to see better?
There's another example of how we all have synesthesia that I'm surprised wasn't mentioned. It's something I've been saying for years. It's the ability to feel emotions through patterns and pitch in in sound. Tell me, how exactly would you explain what exactly music is to an alien race?
~4:44 how would the availability to sensory perception be effected by the structure of the glucose? eg, do bigger molecules disolve into the solution that the gustatory neurons react with in the same quantities, and is there a timeframe that's perceptible? Soz for nerding out on yous
No, we cannot all agree that it's hard to concentrate when someone screams (metal and dark ambient fan).
Well, nobody expects anyone to overlook anything when they're deciding how to mass-produce food. So those clickbait scientific journal articles about tactile-taste crossmodal interaction get a lot of gravity, but we need to remember that the people who are best-suited to inform others about how to improve mass-produced food have been involved in food factories for quite a while (as the owners). This is why that article has been cited 100 times: everyone is hopping on the bandwagon because they aren't sure whether different people see the same colors as each other, or if the colors are different for different people. (in retrospect, I guess we could have called our elementary school teacher's little "paradox" about "not being able to know" what colors look like to others an ancient anti-Mendelian roar)
It doesn't really matter what kind of topical nonsense a scientist is going to force everyone to watch about food. He's certainly never experimented with food in his own home. He's just trying to walk away thinking he's "won" in his solo fight against "greedy people" (or, to be more accurate, "his solo attempt to clean up after regrettable lapses in judgement on behalf of appellate court judges and other such influential people"). Not that anyone ever minded if he were to win. His feelings are just kind of "a tree falling in the forest with no one to hear it", in the end. What was the point of insisting on being critical THAT MUCH? There was no point at all.

All I’ll say is that K.A. Applegate taught me that cheese tastes green.
When I once touched a quickly vibrating bottle I realised I know what sound it made. It was so silent I didn't hear it so I think it's because I touched it and felt the vibration with my hands
Math is red, english is blue, green is science might have to do with the color of the notebooks in the country. In Hungary mathbooks (books with squares), are mostly colored red, books with lines are mostly colored blue. Science may be tricky, because the green books are usually blank. But a lot of wcience teachers requested blanks so we could draw better in them.
When we did geometry we were also asked to use blanks(green) instead of the usual red(squares). So maybe some of these perceptions comes from these.
I've never seen a consistent system like that in the US. Usually every kind of notebook is available in a selection of colors, which is why people form such strong individual preferences.
That would explain why math is blue to some people, the grid books in my country are all formed with blue lines.
As a side note, "we all have X" is one of the most insulting things you can say to someone who has a troublesome diagnosis/condition. I've had *clinicians* say "well, don't we all have a little PTSD" in response to my mention of the PTSD I had from a 3-year traumatic and violent experience.
I'd also argue most are just measuring our mood's impact on our enjoyment of things, or the lenses we view the world through (positive/ negative, pleasant/apathetic/off-putting). ...not a crossover of sense experience.
My version of synesthesia: There are certain flavors that immediately make me think of very specific colors. That's what I meant.
7 is orange 5 is blue and 2 & 4 are shades of green
I see weird patterns in my field of vision with closed eyes when I'm about to fall asleep and hear some sound.
2:36 U might want to google for Pi:
Daniel Tammet, Michael Abrahamson, Suresh Kumar Sharma, & Akira Haraguchi
From the thumbnail, I thought the instrument that made food sour would be the dill piccolo.
Does ANC headphones makes food tastier on flights and aircraft?
John lennon called he wants his glasses back
Bold new look! I like it!
I have mirror touch. I can feel what it feels like when I touch people or animals. It's really weird and has changed my life. I can also feel the sensations my touches produce so things like fighting with my older half brothers (twins three years older) when we were kids was painful even when we got older & I got bigger than them and I started winning. Punching someone is almost counter-productive. If there is something between my skin and theirs, the sensations I feel are diminished through a t-shirt and touching someone with say, a stick produces none. It has helped in my love life, so it's mainly a good thing!
Science is blue. Math is black. English is green. History is blue, but it's like a cornflower blue (science is cobalt). Piano music is another blue, a deep navy. Piano music is also cool, humid, and windless. Guitar music is drier and warmer. Violin music is hot and humid with a breeze. It's also very red. It's the reddest instrument. Banjo music is yellow, and it's a springy post-rain warm. Organ music is dank and damp and purple. It's a bit umami-ish too. Brass instruments are like rich sweet coffee drinks. But they're not brown, they're green. The sound of traffic on a big highway is crunchy and vinegary, but traffic on a city street is sweeter and chewier.
This video is a peachy orange and smells like toasted pecans.
This strikes me the same way as when allistic people say stupid things like "everyone's a little bit autistic". No. No, they're not, and not everyone is a "little bit synaesthetic", nor is someone who feels queasy in the morning and puts on a little weight a "little bit pregnant" in the absence of a fetus.
That shirt design just makes me think of Doctor Who
I think of loads of people/smells/words as shapes. I actually think most of my thoughts are images and shapes, none of those shapes being words in any meaningful order. I have realized as I've grown older that I need to say a lot out loud in order to process the nonsense that's going on in my head
Is it crossmodal interaction when I can’t hear as well without my glasses? I theorise that my brain needs to focus on sight and therefore gives less attention to sound.
Math - Blue
English - Red
Science - Green
History - Yellow
To me, these are hard facts.
One weird thing about me, is that I can’t eat when watching people in mascot suits. It’s so weird and I don’t know why.
One thing I noticed about the first study: to me dry skin isn't smooth, it's rough. So yeah, that end of the scale doesn't make sense.
Exhaust noises make cars feel faster. Apparently. For some people.
I finally woman found a woman with non-stop breath talking. I was worried.
Take a breath, it’s okay.
I Def do Not have the colour and sound overlap at all. The “these subjects are these colours” confuses me. They… don’t align with any colours? They’re subjects.
But sound and Touch/sensation? Yes. Yes. Which is why anybody who open mouth ears around me will never see me during meals again.
What about why I have to turn the radio in the car down to pay attention to what street signs say?
I don't have synesthesia but I associate the concepts (not the typographical words themselves) of math with blue and English with green. I might associate P.E. with orange and maybe history with red. (Interestingly history is one of my favorite subjects and I don't particularly like red.) Science feels like too broad a category so if I wanted to try and associate colors I'd probably break it down into individual disciplines (biology, physics, etc.).
