Creativity is often defined as the ability to come up with new and useful ideas. Like intelligence, it can be considered a trait that everyone – not just creative “geniuses” like Picasso and Steve Jobs – possesses in some capacity.

It’s not just your ability to draw a picture or design a product. We all need to think creatively in our daily lives, whether it’s figuring out how to make dinner using leftovers or fashioning a Halloween costume out of clothes in your closet. Creative tasks range from what researchers call “little-c” creativity – making a website, crafting a birthday present or coming up with a funny joke – to “Big-C” creativity: writing a speech, composing a poem or designing a scientific experiment.

Psychology and neuroscience researchers have started to identify thinking processes and brain regions involved with creativity. Recent evidence suggests that creativity involves a complex interplay between spontaneous and controlled thinking – the ability to both spontaneously brainstorm ideas and deliberately evaluate them to determine whether they’ll actually work.

Despite this progress, the answer to one question has remained particularly elusive: What makes some people more creative than others?

In a new study, my colleagues and I examined whether a person’s creative thinking ability can be explained, in part, by a connection between three brain networks.

Mapping the brain during creative thinking

In the study, we had 163 participants complete a classic test of “divergent thinking” called the alternate uses task, which asks people to think of new and unusual uses for objects. As they completed the test, they underwent fMRI scans, which measures blood flow to parts of the brain.

The task assesses people’s ability to diverge from the common uses of an object. For example, in the study, we showed participants different objects on a screen, such as a gum wrapper or a sock, and asked to come up with creative ways to use them. Some ideas were more creative than others. For the sock, one participant suggested using it to warm your feet – the common use for a sock – while another participant suggested using it as a water filtration system.

Importantly, we found that people who did better on this task also tended to report having more creative hobbies and achievements, which is consistent with previous studies showing that the task measures general creative thinking ability.

After participants completed these creative thinking tasks in the fMRI, we measured functional connectivity between all brain regions – how much activity in one region correlated with activity in another region.

We also ranked their ideas for originality: Common uses received lower scores (using a sock to warm your feet), while uncommon uses received higher scores (using a sock as a water filtration system).

Then we correlated each person’s creativity score with all possible brain connections (approximately 35,000), and removed connections that, according to our analysis, didn’t correlate with creativity scores. The remaining connections constituted a “high-creative” network, a set of connections highly relevant to generating original ideas.

Having defined the network, we wanted to see if someone with stronger connections in this high-creative network would score well on the tasks. So we measured the strength of a person’s connections in this network, and then used predictive modeling to test whether we could estimate a person’s creativity score.

The models revealed a significant correlation between the predicted and observed creativity scores. In other words, we could estimate how creative a person’s ideas would be based on the strength of their connections in this network.

We further tested whether we could predict creative thinking ability in three new samples of participants whose brain data were not used in building the network model. Across all samples, we found that we could predict – albeit modestly – a person’s creative ability based on the strength of their connections in this same network.

Overall, people with stronger connections came up with better ideas.

What’s happening in a ‘high-creative’ network

We found that the brain regions within the “high-creative” network belonged to three specific brain systems: the default, salience and executive networks.

The default network is a set of brain regions that activate when people are engaged in spontaneous thinking, such as mind-wandering, daydreaming and imagining. This network may play a key role in idea generation or brainstorming – thinking of several possible solutions to a problem.

The executive control network is a set of regions that activate when people need to focus or control their thought processes. This network may play a key role in idea evaluation or determining whether brainstormed ideas will actually work and modifying them to fit the creative goal.

The salience network is a set of regions that acts as a switching mechanism between the default and executive networks. This network may play a key role in alternating between idea generation and idea evaluation.

An interesting feature of these three networks is that they typically don’t get activated at the same time. For example, when the executive network is activated, the default network is usually deactivated. Our results suggest that creative people are better able to co-activate brain networks that usually work separately.

Our findings indicate that the creative brain is “wired” differently and that creative people are better able to engage brain systems that don’t typically work together. Interestingly, the results are consistent with recent fMRI studies of professional artists, including jazz musicians improvising melodies, poets writing new lines of poetry and visual artists sketching ideas for a book cover.

Future research is needed to determine whether these networks are malleable or relatively fixed. For example, does taking drawing classes lead to greater connectivity within these brain networks? Is it possible to boost general creative thinking ability by modifying network connections?

The ConversationFor now, these questions remain unanswered. As researchers, we just need to engage our own creative networks to figure out how to answer them.

That isn’t literature too

Paradox - another word for idiocy

I recently reblogged an article from The Conversation about how awesome the Harry Potter books are, but how snobby (some?) literary people are about them. The vitriol and chastisement of the Harry Potter books reminds me of a time when I too was not on the Potter bandwagon. Oh how wrong I was.

Stupid kid’s books. It’s just The Worst Witch with a Chosen One narrative. That’s not literature!

And once again we come to my favourite book chest thumping topic. How worthy is Harry Potter and how wrong have the snobby people been about it?

I think it is worth addressing a few of the arguments that are levelled at JK Rowling and genre fiction in general. Let’s use Rowling as a stand in for all genre authors. Because all genre authors are just as successful and beloved…

Mostly the arguments revolve around Rowling not having the correct goals in her writing. Of course, these supposed goals are rather arbitrary and change depending upon who is deciding what Rowling’s goals should be. Because apparently writing an entertaining book series that sells hundreds of millions of copies, has devoted fans, promotes laudable social principles, and got some kids reading books who wouldn’t have otherwise isn’t enough for some people. They also tend to expect the world from the Harry Potter books, something that I’ll delve into further below.

Take for example this piece by Nicholas Lezard in The Guardian:

Do I need to explain why that is such second-rate writing?

If I do, then that means you’re one of the many adults who don’t have a problem with the retreat into infantilism that your willing immersion in the Potter books represents. It doesn’t make you a bad or silly person. But if you have the patience to read it without noticing how plodding it is, then you are self-evidently someone on whom the possibilities of the English language are largely lost. Source.

Ugh. I’ve got two words for you, Nicholas Lezard, and they are what your mum should have said to your dad on that fateful day.

There is so much to unpack in that small quote. Lezard starts by insulting fans of the books, then says he isn’t insulting them, then insults them again. Someone who could write a paragraph such as this is self-evidently someone upon whom the possibilities of the English language are largely lost. He’s insulting the use of speech identifier verbs whilst failing to understand the audience and style being utilised. If you expect YA to be using the same style as the Man-Booker winners you’re gonna have a bad time.

But why insult fans, young and old, of the series? Why insult Rowling? Although she is probably insulated from such lowly criticism in her gold-lined money castle. He didn’t like something, he can critique it, but he is forgetting that a literary critique stands on argument, not insulting people for disagreeing with him.

This speaks poorly of Lezard and other such critics. In a previous post I discussed literary people defending Fort Literature from the invading Lesser Works. But this is Lezard leading a charge against the peaceful village inhabited by the Lesser Works. He has marked himself the despotic bigoted scourge of Fiction Land, seeking to crush all those who would dare be different from him.

Other critics of Harry Potter have argued that the series didn’t do enough to change the world. This piece comes from the unsupported opinions at The New York Times:

But in keeping with the intricately plotted novels themselves, the truth about Harry Potter and reading is not quite so straightforward a success story. Indeed, as the series draws to a much-lamented close, U.S. statistics show that the percentage of youngsters who read for fun continues to drop significantly as children get older, at almost exactly the same rate as before Harry Potter came along. Source.

Of course, the problem with this argument is that it requires one series by one author to change the lives of all kids worldwide… The article itself cites the series as having sold 325 million copies worldwide in the decade since the first book’s release (a third of that in the USA alone). Out of the 1.9 billion kids and 7 billion people in the world that means only 17% of kids, or 4.6% of people have bought a Harry Potter book (because nobody ever bought the whole series, or two copies of one of the books, or saw a copy in a library). To put that 325 million copies for the entire series in perspective, roughly 175 million people paid to see A film in the cinema that was tenuously about cars. A similar number paid to see the final Harry Potter film. Let’s face it: reading isn’t that popular.

Let’s break this amazing phenomenon down a bit further. There have been several studies that have looked at readers, particularly kids, and how many of them have read the books.

This is a small survey of children (N = 233) looking at Harry Potter fans, but is consistent with other studies and with a Waterstones reader survey the researchers used to validate the small study. You can see that most kids had read the first book, but that quickly dropped off as the series continued. The studies showed that only 25-35% of kids had read all 7 books in the series, with the average fan reading 3.98 books in the series.

Another thing to note is that studies have also found that 46% and 49% had read a Harry Potter book. Or to put it another way, over 50% of kids hadn’t read any Harry Potter books, and many had only tried one (usually the first one). The most popular book series of all time still isn’t read by a majority of people.

But what about JK Rowling’s influence on reading?

This study was of only 650 kids, but it does illustrate that particularly amongst secondary school kids that they were inspired to read. More books, more difficult books, and more fiction – and if someone can point out the difference between non-fiction and fiction I’d much appreciate it.

Another study of a similar size found supporting results:

Many, though not all, of our enthusiasts consider the Potter books a major contributor to both their self-identification as readers and their wider literacy development. Perhaps the most striking change they reported was the confidence and motivation to try more challenging books or more books in general. Thus, the Potter books—particularly the thicker ones—acted as a “Portkey” or “gateway,” transporting readers into the world of more mature fiction. Source.

The increasing complexity and length of the books was cited in both studies as giving people confidence to grow as readers. But it was also noted that one of the reasons given for not reading all of the books in the series was also the increasing complexity and length. In other words you can’t please everyone, especially not kids. Unless you have ice-cream. And the kids aren’t lactose intolerant.

So the problem isn’t that the books are second-rate, nor that they aren’t encouraging people (kids are people too) to read. The problem is that even the most popular book series ever is going to have a limited impact. Rowling has managed to connect with a huge audience – for a book – which has had positive impacts on readers, such that they are more likely to go out and read more books, even the more complex books that keep the literary snobs in a job.

It is a big ask to expect one book series to have improved literacy rates. At the risk of labouring the point – any further – most people don’t read, and most people who do read won’t have read Harry Potter. The problem isn’t Rowling failing to inspire people enough. It isn’t that she wasn’t a good enough writer. The problem is that people love to make lazy attacks on genre fiction. They don’t want to admit that reading is not that popular and that what we have been doing is probably not encouraging new readers. At least Rowling was on the right track.

As Harry Potter turns 20, let’s focus on reading pleasure rather than literary merit

It’s 20 years on June 26 since the publication of Harry Potter and the Philosopher’s Stone, the first in the seven-book series. The Philosopher’s Stone has sold more than 450 million copies and been translated into 79 languages; the series has inspired a movie franchise, a dedicated fan website, and spinoff stories.

Goodreads

I recall the long periods of frustration and excited anticipation as my son and I waited for each new instalment of the series. This experience of waiting is one we share with other fans who read it progressively across the ten years between the publication of the first and last Potter novel. It is not an experience contemporary readers can recreate.

The Harry Potter series has been celebrated for encouraging children to read, condemned as a commercial rather than a literary success and had its status as literature challenged. Rowling’s writing was described as “basic”, “awkward”, “clumsy” and “flat”. A Guardian article in 2007, just prior to the release of the final book in the series, was particularly scathing, calling her style “toxic”.

My own focus is on the pleasure of reading. I’m more interested in the enjoyment children experience reading Harry Potter, including the appeal of the stories. What was it about the story that engaged so many?

Before the books were a commercial success and highly marketed, children learnt about them from their peers. A community of Harry Potter readers and fans developed and grew as it became a commercial success. Like other fans, children gained cultural capital from the depth of their knowledge of the series.

My own son, on the autism spectrum, adored Harry Potter. He had me read each book in the series in order again (and again) while we waited for the next book to be released. And once we finished the new book, we would start the series again from the beginning. I knew those early books really well.

‘Toxic’ writing?

Assessing the series’ literary merit is not straightforward. In the context of concern about falling literacy rates, the Harry Potter series was initially widely celebrated for encouraging children – especially boys – to read. The books, particularly the early ones, won numerous awards and honours, including the Nestlé Smarties Book Prize three years in a row, and were shortlisted for the prestigious Carnegie Medal in 1998.

Criticism of the literary merit of the books, both scholarly and popular, appeared to coincide with the growing commercial and popular success of the series. Rowling was criticised for overuse of capital letters and exclamation marks, her use of speech or dialogue tags (which identify who is speaking) and her use of adverbs to provide specific information (for example, “said the boy miserably”).

The criticism was particularly prolific around the UK’s first conference on Harry Potter held at the prestigious University of St Andrews, Scotland in 2012. The focus of commentary seemed to be on the conference’s positioning of Harry Potter as a work of “literature” worthy of scholarly attention. As one article said of J.K. Rowling, she “may be a great storyteller, but she’s no Shakespeare”.

Even the most scathing of reviews of Rowling’s writing generally compliment her storytelling ability. This is often used to account for the popularity of the series, particularly with children. However, this has then been presented as further proof of Rowling’s failings as an author. It is as though the capacity to tell a compelling story can be completely divorced from the way a story is told.

Writing for kids

The assessment of the literary merits of a text is highly subjective. Children’s literature in particular may fare badly when assessed using adult measures of quality and according to adult tastes. Many children’s books, including picture books, pop-up books, flap books and multimedia texts are not amenable to conventional forms of literary analysis.

Books for younger children may seem simple and conventional when judged against adult standards. The use of speech tags in younger children’s books, for example, is frequently used to clarify who is talking for less experienced readers. The literary value of a children’s book is often closely tied to adults’ perception of a book’s educational value rather than the pleasure children may gain from reading or engaging with the book. For example, Rowling’s writing was criticised for not “stretching children” or teaching children “anything new about words”.

Many of the criticisms of Rowling’s writing are similar to those levelled at another popular children’s author, Enid Blyton. Like Rowling, Blyton’s writing has described by one commentator as “poison” for its “limited vocabulary”, “colourless” and “undemanding language”. Although children are overwhelmingly encouraged to read, it would appear that many adults view with suspicion books that are too popular with children.

There have been many defences of the literary merits of Harry Potter which extend beyond mere analysis of Rowling’s prose. The sheer volume of scholarly work that has been produced on the series and continues to be produced, even ten years after publication of the final book, attests to the richness and depth of the series.

The ConversationA focus on children’s reading pleasure rather than on literary merit shifts the focus of research to a different set of questions. I will not pretend to know why Harry Potter appealed so strongly to my son but I suspect its familiarity, predictability and repetition were factors. These qualities are unlikely to score high by adult standards of literary merit but are a feature of children’s series fiction.
