Your Brain on Fiction

18 Mar

A very interesting article by Annie Murphy Paul appeared in the New York Times yesterday. It was titled “Your Brain on Fiction” and deals with how the written word affects our brains. In the article, she talks about several studies done with functional MRIs (fMRI). A functional MRI looks at brain activation by revealing changes in blood flow. If a certain area of the brain is stimulated, then that area will receive increased blood flow and this can be measured with a functional MRI. Such testing is currently being looked at to perhaps develop a more reliable lie detector. It appears that different parts of the brain activate when someone is remembering an event as opposed to making it up. Hopefully, this technique will help to distinguish truth telling from fabrication, but that’s another story.

The areas of our brain that are concerned with language processing are predominantly Broca’s area and Wernicke’s area and their interconnecting neurological tracts. These areas are activated when we read. But it is also been discovered, that depending on the word or words read, other areas of the brain are also activated. For example, the word “cinnamon” not only activates the above language areas but also the olfactory (smell) area of the brain. This also seems to happen with words such as perfume and coffee but not with words such as chair or key, since these have no associated sensory meaning.

 
Even more fascinating is that there is evidence that metaphorical terms cause more brain activation then do more concrete ones. Researchers found that saying a singer had a “pleasing” voice did not cause the same activation as saying the singer had a “velvet” voice. Of course the word “velvet” is more metaphorical and sensory than is the word “pleasing,” which tends toward the generic. Similarly the the term “strong hands” causes less activation than the term “leathery hands,” where again a difference in sensory connotation is obvious.

For the writer, this means that using more metaphorical terms will impact your reader on a more emotional and sensory level than using simple concrete terms. I guess you could say that vivid writing is more “stimulating” then bland writing.

    Writing for all the senses does seem like a great approach, and it opens up many more avenues for the writer. Thanks for this interesting post, Doug.

    Good argument to write using all five senses–and also, I wonder how this ties into the research coming out on how digital media are processed in a more passive way than print text?

    Fascinating info, Doug! I’m always trying to suggest that my writing clients use more sensory images to bring the scene to life for the readers – and this research certainly reinforces it! Thanks for sharing this info.

    And I love your new blog look! Awesome!

      And it looks like there is a scientific basis for it.

    Choice of words make all the difference in fiction – inappropriate word choice from a writer can ruin a passage or make it memorable. And I would like a follow up on the lie-detector test. I have heard if a person glances one way (left or right) when answering a question, you can tell if they are telling a lie or telling the truth.

      That’s called neurolinguistic programming and like most techniques to assess deception is controversial.

    Love this, Doug! It’s fun to layer scenes with sensory words, but also important not to overdo–it’s more like seasoning. A little salt and pepper improves the taste but too much spoils the soup.

    I’d also been told about the body language “tells” you describe as the neurolinguistic programming. Good to know it’s controversial.
