Reading and Action Meet in the Brain

A new brain-imaging study is shedding light on what it means to "get lost" in a good book — suggesting that readers create vivid mental simulations of the sounds, sights, tastes and movements described in a textual narrative while simultaneously activating brain regions used to process similar experiences in real life.

"Psychologists and neuroscientists are increasingly coming to the conclusion that when we read a story and really understand it, we create a mental simulation of the events described by the story," said Jeffrey M. Zacks . . . .

The study, forthcoming in the journal Psychological Science, is one of a series in which Zacks and colleagues use functional magnetic resonance imaging (fMRI) to track real-time brain activity as study participants read and process individual words and short stories.

. . .[F]indings demonstrate that reading is by no means a passive exercise. Rather, readers mentally simulate each new situation encountered in a narrative. Details about actions and sensations are captured from the text and integrated with personal knowledge from past experiences. These data are then run through mental simulations using brain regions that closely mirror those involved when people perform, imagine or observe similar real-world activities. . . .

Changes in characters' locations (e.g., "went through the front door into the kitchen") were associated with increases in regions in the temporal lobes that are selectively activated when people view pictures of spatial scenes.

I post this comment from my friend Gene Glass of Arizona State University, after I sent him the item via email: "Interesting in that it recalls McLuhan's hot vs cool media distinction. Reading and radio are cool media because you must actively create imagery to participate in them. Movies and TV are hot because they do the imaging work for you. It would be interesting to see the brain wave activity of people watching a movie vs reading the movie's script."
