A mark on a page, an online meme, a fleeting sound. How can these seemingly insignificant stimuli lead to acts as momentous as participation in a racist rally or the massacre of innocent worshippers? Psychologists, neuroscientists, linguists, and philosophers are developing a new theory of language understanding that’s starting to provide answers.
Current research shows that humans understand language by activating sensory, motor and emotional systems in the brain. According to this new simulation theory, just reading words on a screen or listening to a podcast activates areas of the brain in ways similar to the activity generated by literally being in the situation the language describes. This process makes it all the more easy to turn words into actions.
As a cognitive psychologist, my own research has focused on developing simulation theory, testing it, and using it to create reading comprehension interventions for young children.
Traditionally, linguists have analyzed language as a set of words and rules that convey ideas. But how do ideas become actions?
Simulation theory tries to answer that question. In contrast, many traditional theories about language processing give action short shrift.
Simulation theory proposes that processing words depends on activity in people’s neural and behavioral systems of action, perception and emotion. The idea is that perceiving words drives your brain systems into states that are nearly identical to what would be evoked by directly experiencing what the words describe.
Consider the sentence “The lovers held hands while they walked along the moonlit tropical beach.” According to simulation theory, when you read these words, your brain’s motor system simulates the actions of walking; that is, the neural activity elicited by comprehending the words is similar to the neural activity generated by literal walking. Similarly, your brain’s perceptual systems simulate the sight, sounds and feel of the beach. And your emotional system simulates the feelings implied by the sentence.
So words themselves are enough to trigger simulations in motor, perceptual and emotional neural systems. Your brain creates a sense of being there: The motor system is primed for action and the emotional system motivates those actions.
Then, one can act on the simulation much as he’d act in the real situation. For example, language associating an ethnic group with “bad hombres” could invoke an emotional simulation upon seeing members of the group. If that emotional reaction is strong enough, it may in turn motivate action – maybe making a derogatory remark or physically lashing out.
Although simulation theory is still under scientific scrutiny, there have been many successful tests of its predictions. For example, using neuroimaging techniques that track blood flow in the brain, researchers found that listening to action words such as “lick,” “pick” and “kick” produces activity in areas of the brain’s motor cortex that are used to control the mouth, the hand and the leg, respectively. Hearing a sentence such as “The ranger saw an eagle in the sky” generates a mental image using the visual cortex. And using Botox to block activity in the muscles that furrow the brow affects the emotional system and slows understanding of sentences conveying angry content. These examples demonstrate the connections between processing speech and motor, sensory and emotional systems.
Recently, my colleague psychologist Michael McBeath, our graduate student Christine S. P. Yu and I discovered yet another robust connection between language and the emotional system.
Consider pairs of single-syllable English words that differ only in whether the vowel sound is “eee” or “uh,” such as “gleam-glum” and “seek-suck.” Using all such pairs in English – there are about 90 of them – we asked people to judge which word in the pair was more positive. Participants selected the word with the “eee” sound two-thirds of the time. This is a remarkable percentage because if linguistic sounds and emotions were unrelated and people were picking at the rate of chance, only half of the “eee” words would have been judged as the more positive.
We propose that this relation arose because saying “eee” activates the same muscles and neural systems as used when smiling – or saying “cheese!” In fact, mechanically inducing a smile – as by holding a pencil in your teeth without using your lips – lightens your mood. Our new research shows that saying words that use the smile muscles can have a similar effect.
We tested this idea by having people chew gum while judging the words. Chewing gum blocks the systematic activation of the smile muscles. Sure enough, while chewing gum, the judged difference between the “eee” and “uh” words was only half as strong. We also demonstrated the same effects in China using pairs of Mandarin words containing the “eee” and “uh” sounds.
Of course, motivating someone to commit a hate crime requires much more than uttering “glum” or “suck.”
But consider that simulations become quicker with repetition. When one first hears a new word or concept, creating its simulation can be a mentally laborious process. A good communicator can help by using hand gestures to convey the motor simulation, pointing to objects or pictures to help create the perceptual simulation and using facial expressions and voice modulation to induce the emotional simulation.
It makes sense that the echo chamber of social media provides the practice needed to both speed and shape the simulation. The mental simulation of “caravan” can change from an emotionally neutral string of camels to an emotionally charged horde of drug dealers and rapists. And, through the repeated simulation that comes from repeatedly reading similar posts, the message becomes all the more believable, as each repetition produces another instance of almost being there to see it with your own eyes.
Psycholinguist Dan Slobin suggested that habitual ways of speaking lead to habitual ways of thinking about the world. The language that you hear gives you a vocabulary for discussing the world, and that vocabulary, by producing simulations, gives you habits of mind. Just as reading a scary book can make you afraid to go in the ocean because you simulate (exceedingly rare) shark attacks, encountering language about other groups of people (and their exceedingly rare criminal behavior) can lead to a skewed view of reality.
Practice need not always lead down an emotional rabbit hole, though, because alternative simulations and understandings can be created. A caravan can be simulated as families in distress who have the grit, energy and skills to start a new life and enrich new communities.
Because simulation creates a sense of being in a situation, it motivates the same actions as the situation itself. Simulating fear and anger literally makes you fearful and angry and promotes aggression. Simulating compassion and empathy literally makes you act kindly. We all have the obligation to think critically and to speak words that become humane actions.

This is exciting and revolutionary information, supporting retroactively the likes of Neville Goddard and many, many more.
I would suggest to commenter Ms. Stevenson: You want to offer counter-arguments but end up repeatedly proving the article. What
You contradict yourself, first denying the author’s premise and then nodding to it by pointing to individuals being, ahem, SHOWN (are there no words, then, in these movies?) something which ignites desire for change “…A Clockwork Orange, where minds were changed by seeing a reality and understanding their part in it…” What better example could you have offered to support the author’s explanation of current linguistic science?! Alex’s character wasn’t changed through some visually excited moral shift; he was brainwashed Pavlov-style through his eyes, ears and other senses into revulsion toward violence. And remember, eventually he returned to violence despite these external efforts, because they failed to successfully override that which he had accepted as primary internal programming. That processing area remained hidden and dysfunctional.
How could the brain possibly be the driver, as you suggest? It operates in a vacuum, then? Of what use and impact the five (six) senses? No; our output is dependent upon two things: input and the processing thereof. We mustn’t only guard our output (mouth) and count upon social pressure/socially determined “norms”; that focus been actively demonstrated by several societies past and current (and political parties/movements) to backfire into hellish repressive timespans and the effectively diarrheal responsive social movements then necessary to re-open minds and societal structures.
Checking input at the personal door of the five senses to the greatest degree consciously possible, and sending it through fully engaged processors, is the answer to productive output. Input and processing already happen by default, as the author notes within the basic premise. What will we create when we selectively examine the input, not to mention when we shine the light of self-awareness upon the processors, constantly detoxify their output?
“You are what you eat” applies to the intake from all senses, not just the mouth. Or, if you prefer these terms: “Finally, brethren, whatsoever things are true, whatsoever things are honest, whatsoever things are just, whatsoever things are pure, whatsoever things are lovely, whatsoever things are of good report; if there be any virtue, and if there be any praise, think on these things.” Phi. 4:8
The view expressed in your comment abdicates personal responsibility. Victims, we. The science presented in the article gives us instead a thrust at self-accountability. We are what we think about.
The power of words – their effect on the speaker and the hearer – has been known, discussed, written and preached about for as long as there has been language. Didn’t everyone’s mother chide “if you cannot say anything nice, don’t say anything at all”? While this article about the actual brain activity caused by hearing certain types of words is interesting, as humans we are not victims of the speech of those around us or of our own. We may get a certain involuntary neurological reaction to a word but we also have the ability to determine if what we hear is true or not by tempering it with our experiences, opinions and knowledge. To use the author’s example, “a caravan can be SIMULATED ss families in distress..” – yes, the word caravan can bring that picture to my mind; however, if with my own eyes, I observe something quite different I will accept the evidence of my eyes rather than the fabricated picture the word brought to mind. It seems that the author is proposing that by merely changing our language, we can change our behavior. Clearly not or liars would hear their own lies and believe them and become more honest. Any change begins in with personal desire; something — a loss, a gain, a painful or embarrassing episode, that shines the light of reality on someone personally — causes a person to say “I want to be better” nicer, kinder, more generous. Think Ebenezer Scrooge, or even A Clockwork Orange – where minds were changed by seeing a reality and understanding their part in it, and wanting to return to their better self or to be a different better person. People say hateful things because first they hate. “Sow a thought, reap an action…” Our brain is the driver, not our ears. This doesn’t mean we don’t need to guard our mouths – because we do; but notice WE must guard OUR mouths – guarding someone else’s mouth with laws or word police or classifying speech isn’t going to change people if they are not personally convicted to change. The best we can do is make it socially unacceptable – and that is “socially” (not legally) which can be far more powerful.
