Last week I reblogged an article about some new research into what makes us creative. This week I’m sharing a video from one of my favourite YouTube channels, which essentially covers the same work. But this one is a video!
Since this is going to be a three part series, I’ll update this post as the other videos are released.
This is an interesting short video featuring Suzy Jackson, voice artist, recording an audiobook at Audible Studios.
Joanna Penn has also interviewed a number of people on her podcast about audiobooks, which are worth listening to.
I’m quite the fan of audiobooks. Being able to read a book while I’m exercising or commuting has been a life changer for me. There is something about having headphones in that stops people interrupting you to ask what you’re reading. Sorry, not stops, but certainly lowers the number of interruptions.
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 modelling 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 act 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.
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?
For now, these questions remain unanswered. As researchers, we just need to engage our own creative networks to figure out how to answer them.
This will be a wonderful opportunity to have time and space to write. Here’s the blurb for the story:
Here at Evil Corp we have been successfully carving a path toward world domination for 15 years. With our dedicated staff we want to have you serve our every whim.
Your family deserves the security and friendly authoritarian rule that you could expect from an organisation like Evil Corp, but with the personal touches that only a caring and understanding community minded team can offer.
Have you bowed down to Evil Corp?
