‘Kick the habit’ lights up the brain’s motor cortex
When your readers kick, the motor cortex in their brains light up. If they read, “the player kicked the ball,” that cortex lights up as if they’re kicking.
But what if they read, “The patient kicked the habit”? Or “The villain kicked the bucket”?
We know that descriptive words light up the brain. But do readers’ brains light up if they read metaphors? And what about clichés?
Metaphors stimulate the brain.
Yes … and no, according to a new area of neuroscience. For this research, volunteers in fMRI scanners read literal, metaphorical and idiomatic (clichéd) sentences.
The results?
“When you read action-related metaphors,” Valentina Cuccio, a philosophy postdoc at the University of Palermo, Italy, told IEEE Spectrum, “you have activation of the motor area of the brain.”
Same thing’s true of textural metaphors, according to a 2012 study at Emory University. Read “He has leathery hands,” and the part of your brain responsible for feeling textures — aka the somatosensory cortex — lights up.
The brain doesn’t respond to clichés.
But clichés? Does the motor cortex light up when people read, “The villain kicked the bucket”?
Not so much, says Lisa Aziz-Zadeh, a psychology professor at the University of Southern California. In 2006, Aziz-Zadeh and her team found that idioms such as “biting off more than you can chew” did not activate the motor cortex.
Rutvik Desai, an associate professor of psychology at the University of South Carolina, agrees. His team learned in 2011 that the more idiomatic the metaphor was, the less the motor system got involved.
“When metaphors are very highly conventionalized, as is the case for idioms,” Desai reported, “engagement of sensory-motor systems is minimized or very brief.”
So you could build your executive’s message around sad clichés like “breaking down the silos” and “taking it to the next level.” Just don’t expect your readers’ brains to respond.
Why use metaphor?
Theorists from Aristotle to contemporary academic researchers agree: There is power in metaphor.
Metaphor makes messages more:
- Understandable. Our conceptual system is metaphorical, say researchers George Lakoff and Mark Johnson. That means we can help people think — we can clarify complex concepts — through analogy.
- Persuasive. Study after study shows that metaphoric language is more persuasive than literal language.
- Believable. Ads with metaphors were 21% more credible than ads without them, according to a study by Mark F. Toncar and James M. Munch.
- Important. Participants in the Toncar study saw ads with metaphors as 26% more important than ads with literal claims.
- Memorable. Ads with metaphors were remembered almost twice as well as ads with literal descriptions in a study by Edward F. McQuarrie and David G. Mick.
- Readable. An archival study of 854 ads showed that Starch Read Most scores — the percentage of people who read most of the ad — were higher for ads with a metaphor in the headline than with a literal headline. Audience members also may spend more time processing metaphors than just plain facts.
- Likeable. Speakers and other communicators who use metaphors are deemed more appealing than those who do not. They’re seen to be more competent and dynamic and to have better character. And readers like metaphors because it feels good to figure them out.
Tip: Use this list next time one of your approvers wants to strip the metaphors out of your copy.
Make Magic with Metaphor
Charm readers with analogies and comparisons
It’s tempting to call metaphor the magic spell in a writer’s repertoire, the Penn and Teller of the page.
Metaphor has the power to persuade far better than literal language. It lets you say in five words what would otherwise take five paragraphs to explain.
It makes readers’ brains light up, helps them think more broadly about your message — even (ahem!) makes you look more attractive.
At Master the Art of Storytelling — our two-day hands-on creative-writing master class on Feb.19-20, 2019, in San Diego — you’ll want to master a few tricks before you step onto the stage. In this session, you’ll learn how to charm readers with the magic of metaphor:
- Get the zombies out of your message: Don’t let Dead and Dead2 metaphors eat your readers’ brains.
- Craft a compelling metaphor with our fill-in-the-blanks formula.
- Polish your metaphor: Learn which kinds of metaphors to choose, which to avoid and where in your message to place them from 41 academic studies covering 50 years of research.
