Are you one of those people who, no matter how much you are enjoying it, simply cannot wait to finish the book you are reading when another interesting title catches your eye? Me too. Unfortunately, a busy schedule limits my dedicated reading time. So what’s a bibliophile to do?

Simple. I read multiple books at the same time.

Some of my friends exclaim, “I don’t know how you can do that! If I tried to read more than one book at a time, my brain would explode.”

Well, since I do perform this brain-multitasking feat on a daily basis, I thought I’d do some research to determine whether it really was hurting – or helping – my cognitive abilities as I age.

Information, other than individual opinions on the subject, was difficult to find. Of course, any search including the term “multitasking” brings up a plethora of negative articles claiming how dangerous this can be, like texting while driving.

“Split-focus” was another term I came across often, which, it is claimed, reduces focus and productivity. I even found several bloggers who claimed it was a disgrace to “cheat” a wonderful book out of your full attention.

Then I learned a brand new term for the habit: “poly-reader,” as opposed to a monogamous or serial reader.

Is It OK to Read More Than One Book at a Time?

Wow. I didn’t know reading more than one book at a time placed me in the non-monogamous category. So… I’m cheating on the first book with the second and third? Or is it more like polygamy, where all the books willingly consent to share my attention?

Then there’s the question of multiple media: physical book vs. eBook vs. audiobook. Can you mix these without the dose becoming lethal?

I say these theories are hogwash. First of all, I not only have at least two or three physical books on my nightstand at all times, but I also have a Kindle app on my phone (I know, this is really bad for my eyesight. But that’s a subject for another post…).

Since I’m also a huge fan of audiobooks, I virtually never listen to music on my car radio. I’m always listening to a book.

Interestingly, there has been some scientific research on how the brain responds to reading a physical vs. and eBook. From this 2009 article by Jonah Lehrer on ScienceBlogs, I learned that different parts of the brain respond differently to different types of text.

According to Lehrer, “one of the most interesting findings regarding literacy and the human cortex is the fact that there are actually two distinct pathways activated by the sight of letters.”

Researcher Stanislas Dehaene studied people’s brain waves under fMRI, and concluded that text in a familiar format, i.e., the printed page, stimulates the ventral reading pathway. This allows the reader to decipher and understand the content effortlessly.

When the format changes, however, as text on an eReader or computer screen, another part of the brain is triggered: the dorsal pathway. This is the more simplistic, basic process, and it’s the way we all learned how to read – by sounding out the syllables.

Why the Brain Loves Books

In layman’s terms, when reading a physical book vs. an eBook, the words are transported into our brains via two completely different pathways.

So, how can this be bad? We exercise our bodies in multiple ways, don’t we? It seems to me that exercising our brains in multiple ways can do nothing but help keep our minds in shape – and sharp.

Then we move on to the third medium: audiobooks. Now we have a whole different set of cognitive processes going on. I found some sources that claimed listening to an audiobook vs. reading one was “cheating.”

The foundation for this theory is that listening turns an active process into a passive one. But the author of this article on The Science of Us, Melissa Dahl, disagrees.

She cites science writer Olga Khazan, who noted in 2011, that a “1985 study found listening comprehension correlated strongly with reading comprehension.” So no, listening vs. reading isn’t cheating. It’s just absorbing the information via a different sensory route.

Listening to Audio Books Is Just Like Brain Exercise

Again, how can this be bad? By listening to an audiobook, we are utilizing yet another part of our brain. Exercising it. Exercise is good.

But now, the real question is, what about us poly-readers? What about those of us who not only partake of multiple forms of reading material, but more than one at the same time? Are we breaking some moral code? Are we totally overloading our brains and running the risk of burning out a neural pathway?

I don’t think so, and neither does Eddie Wharton, as he claims on his Working Theory blog. Most of the books Wharton reads are nonfiction, and he claims that reading more than one at a time has had three distinct and unexpected benefits, namely:

1. He enjoys reading more.
2. He finds himself “stumbling on new insights.”
3. He “progress(es) through them all slower. The books have more time to bounce off of different life situations.”

And finally, in this wonderful article on AgileLifestyle, author Tony Khuon describes this kind of voracious reading as “more like a superpower.”

Since 2012, he has consistently reached his goal of 150 books in one year. He recommends, when reading books in parallel, to select three different kinds of books, i.e., a genre novel, a literary work and a nonfiction title.

That is exactly what I do.

Different Genres for Different Devices

The book(s) on my bedside table are nonfiction, craft books that help me to improve the novels I write. The book on my Kindle app is a genre fiction, usually one a fellow author has asked me to read and review. The audiobook booming out from my car’s speakers on my commute is usually a literary title or a classic.

I turn 60 in just a few short weeks. So far this year, I’ll bet I’ve “consumed” almost a hundred books in their various formats, though I haven’t kept count. Do I feel sharper, and smarter, and more motivated? Yes, indeed, I do. I walk, do yoga and ride a horse to exercise my body, and I read – profusely and diversely – to exercise my brain.

Are you a monogamous or a poly-reader? Do you enjoy books in multiple formats, or primarily one? I’d love to hear your thoughts in the comments below.
