People with efficient brains tend to have spare capacity.
Daydreaming is a sign of being more creative and having higher intelligence, research suggests.
Those who report more daydreaming have higher intellectual abilities and their brains work more efficiently.
People with efficient brains tend to have spare capacity, so it is natural for the mind to wander.
Wandering minds and intelligence
The conclusions come from a study in which over 100 people stared at a fixed point for five minutes while their brains were scanned.
The aim was to see how the areas of the brain worked together when they were given nothing in particular to do.
The results showed that those with more efficient brains were also smarter and more creative.
Dr Eric Schumacher, study co-author, said:
“People with efficient brains may have too much brain capacity to stop their minds from wandering.
People tend to think of mind wandering as something that is bad.
You try to pay attention and you can’t.
Our data are consistent with the idea that this isn’t always true.
Some people have more efficient brains.”
Brain efficiency insights
One sign of an efficient brain is being able to zone in and out of conversations without missing anything.
Dr Schumacher said:
“Our findings remind me of the absent-minded professor — someone who’s brilliant, but off in his or her own world, sometimes oblivious to their own surroundings.
Or school children who are too intellectually advanced for their classes.
While it may take five minutes for their friends to learn something new, they figure it out in a minute, then check out and start daydreaming.”
Ms Christine A. Godwin, the study’s first author, wants to examine exactly when mind wandering could be useful and when not:
“There are important individual differences to consider as well, such as a person’s motivation or intent to stay focused on a particular task.”
The study was published in the journal Neuropsychologia (Godwin et al., 2017).
Hello, and welcome to PsyBlog. Thanks for dropping by.
This site is all about scientific research into how the mind works.
It’s mostly written by psychologist and author, Dr Jeremy Dean.
I try to dig up fascinating studies that tell us something about what it means to be human.
