People with high intelligence tend to have this quality.
Extravert get higher scores on IQ tests, a study finds.
People who are outgoing, talkative and energetic perform better on tests of verbal and abstract reasoning, psychologists found.
Extraverts are generally self-confident and cheerful and can also be impulsive, sensation-seekers.
The conclusions come from a study that tested the effects of background music on how people perform on IQ tests.
The study also revealed that extraverts are better at dealing with noisy conditions when carrying out intellectual tasks.
Introverts find background noise and music much more distracting.
For the study, 118 people took IQ tests, sometimes in silence and other times with background noise.
The background noise was either music or simulated office noise.
The results showed that extraverts got higher scores on the IQ tests, whether it was noisy or not.
However, everyone tended to perform better on the test in silence.
So, background noise generally made everyone’s performance worse.
The worst type of noise for performance was the simulated office noise.
Still, extraverts coped much better on the tests in noisy conditions than introverts.
The study’s authors write:
“This study found a positive correlation between extraversion and IQ, suggesting the relationship between intelligence and extraversion may be a bit more complex than it appears at first sight.[…]
…extraversion and introversion are intimately associated with different intellectual styles and intelligence profiles.
Introverts were found to perform relatively better on verbal tests, and extraverts on performance tests.”
The study was published in the journal Applied Cognitive Psychology (Dobbs et al., 2011).
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.
