Vowels Control Your Brain

Here’s something you should know about yourself. Vowels control your brain.

Drawing of "O"

Robert Krulwich/NPR

“I”s make you see things differently than “O”s. Here’s how. Say these words out loud:

  • Bean
  • Mint
  • Slim

These “I” and “E” vowels are formed by putting your tongue forward in the mouth.

That’s why they’re called “front” vowels.

Now, say:

  • Large
  • Pod
  • Or
  • Ought
Forward vowels vs. back vowels

With these words, your tongue depresses and folds back a bit. So “O”, “A” and “U” are called “back” of the throat vowels.

OK, here’s the weird part.

When comparing words across language groups, says Stanford linguistics professor Dan Jurafsky, a curious pattern shows up: Words with front vowels (“I” and “E”) tend to represent small, thin, light things.

Back vowels (“O” “U” and some “A”s ) show up in fat, heavy things.

It’s not always true, but it’s a tendency that you can see in any of the stressed vowels in words like little, teeny or itsy-bitsy (all front vowels) versus humongous or gargantuan (back vowels). Or the i vowel in Spanish chico (front vowel meaning small) versus gordo (back vowel meaning fat). Or French petit (front vowel) versus grand (back vowel).

Try this yourself.

Frish V. Frosh

Robert Krulwich/NPR

If I make up two words, “Frish” and “Frosh” and tell you each is about to become a new ice cream, which of the two seems richer, heavier?

For me, “Frosh,” (with the back vowel “o”) seems creamier. I don’t know why. Just feels that way. And not just to me. A study in the Journal of Consumer Research found most people imagined Frosh creamier than Frish.

Here’s another example. Richard Klink, a marketing professor at Loyola College in Maryland created a test using two sets of names. They were nonsense names, chosen at random:

Nidax vs. Nodax and Detal vs. Dutal

And then, slapping these names on various imaginary products, he asked a group of people:

  • Which brand of laptop seems bigger; Detal or Dutal?
  • Which brand of vacuum cleaner seems heavier, Keffi or Kuffi?
  • Which brand of ketchup seems thicker, Nellen or Nullen?
  • Which brand of beer seems darker, Esab or Usab?

“In each case,” reports Professor Jurasky, “the participants in the study tended to choose the product named by back vowels (dutal, nodax) as the larger, heavier, thicker, darker product. Similar studies have been conducted in various other languages.”

Jurasky then wondered, Do businesses know this about vowels?

For example, would an ice cream company (looking to create a rich, creamy and satisfying product,) and a cracker manufacturer, (looking to make something, thin, light and crackily) use different vowels?

He thought they might, so, on his blog, he writes:

To test the hypothesis I downloaded two lists of food names from the web. One was a list of 81 ice cream flavors that I constructed by including every flavor sold by either Haagen Dazs or Ben & Jerry’s. The second was a list of 592 cracker brands from a dieting website. For each list, I counted the total number of front vowels and the total number of back vowels (details of the study are here). The result, shown in the table [below], is that ice creams names indeed have more back vowels and cracker names have more front vowels.

Ice cream companies mix in lots of “O”s and “A”s, says Jurasky, like…

Rocky Road, Jamoca Almond Fudge, Chocolate, Caramel, Cookie Dough, Coconut

But the cracker people stick pretty much to “E”s and “I”s.

Cheese Nips, Cheez It, Wheat Thins, Pretzel thins, Ritz, Krispy, Triscuit, Thin Crisps, Cheese Crisps, Chicken in a Biskit, Snack sticks, Toasted chips, Ritz bits

But Why?

Why do we associate “front” vowels with small, thin light things and “back” vowels with big, solid, heavy things?

Cheese vs. Boo.

Robert Krulwich/NPR

Two linguists, John Ohala and Eugene Morton proposed that over evolutionary time, humans instinctively associate pitch with size. Lions, bears, seals make low sounds, canaries, mice, rabbits higher sounds. Not always, but enough of the time that when we hear a low frequency (even in an “O” or a “U”) we may think big and heavy, whereas higher frequencies (even in “I’s and “E”s) suggest small and light.

The Origin Of The Smile?

Dan Jurasky goes even further. Scholars have noticed, he says, that when people say “Boo!”, they form an o-shape with their lips and mouth, and look aggressive and a little dangerous.

But use the “front” vowels, like “I” and “E”, your mouth and lips will widen into a kind of smile. Why do we say “cheese” when it’s time to take the picture? Why does the word smile contain an “I”? These front vowels, he says, are the “smile” vowels. One day they may even explain why we smile, but in the meantime, the big news is that it’s old fashioned to think of vowels as just sounds.

They are more than that: they are little strings that pull on our brains and it turns out, “I”s pull us to different places than “O”s.

This is preciseloy the reason ESL students (English as a second language)stubbornly refuse proper modern pronunctiation.
Many opf them (romance languages and some Asians) reach the part of their brain that signals negative associations- like shame or regret when they form their speech organs to make vowell sounds.
Also the big reasons English mother tongue speakers stubbornly refuse proper foreign vowell sounds (and some consonants like the rolled “R”).
We are busy at work in our subconsciousness and forcing things upon ourselves we are not even remotely aware of .
We “translate” instead of thinking in the foreign language in a desperate attempt to preserve our identity against all the new sounds in the new learned language.
Accenting is no magic trick- it only requires an acceptance and ear training.
Robert, this is a long overdue examination of the vowel mechanisms.
Use a mirror when reciting second language sounds- esüecially vowels.
Listen to the sounds being sung- like on recordings or, when available origional film dialog.
German, for but one example has: “ü”,”ä”,”ö” as seperate vowel components to their : “u”,”a”,”o”- only silliness or sloppiness prevents proper pronunctiation.

Do we elect presidents based on whether we want gravitas or smiley? Obama v Gingrich may tell us. Mitt Romney is just too circular.

When I was about 3 or 4 years old I had this image of a tonal comparison of my family and our cousins’ family–who lived about a block away. The tone for our family was “eeeeee” and the tone for their family was “uuuuuuh.” A few years later, at maybe the age of 10, I recalled this memory and decided that the basis for it was the words “teen” and “adult.” That the teenagers in our family were dominant and the adults in their family were dominant.

@M L: You are quite a lot wrong and a little bit right about what you’re saying. To clear it up for you, the common way to describe vowels is through two dimensions; namely openness/closedness (yes, of the jaw!)and frontness/backness of the tongue. So ‘ee’ as in ‘me’ and ‘ooh’ as in ‘you’ are basically the same in terms of jaw position but completely different tongue position (‘ee’ is front and ‘ooh’ is back).

It turns out, as is explained in the article, frontness/backness is the measure that it statistically significant, not openness/closedness of the jaw. Jurafsky is also a good computer scientist, so it follows that it would be trivial for him to look at the openness measure as well and since it wasn’t the predictive measure, he didn’t report it.

I hope that helps.
