Why Do Women Talk So Much?

Because their brains may be built that way. So says a University of Maryland School of Medicine study published in the Journal of Neuroscience, which found that young girls have a greater abundance of a protein that’s associated with language development in mammals. And this might explain why men tend to be less talkative than women.

The Maryland study measured the amount of the Foxp2 protein in the brains of rat pups. Their findings: four-day-old male rats had higher levels of Foxp2 and were more vocal than females.

In a subsequent investigation, the researchers found that young girls also have higher levels of Foxp2, sometimes knows as the “language gene,” than equally aged boys.

“This study is one of the first to report a sex difference in the expression of a language-associated protein in humans or animals,” said Margaret McCarthy, PhD, one of the study’s authors. “The findings raise the possibility that sex differences in brain and behavior are more pervasive and established earlier than previously appreciated.”

As might be expected, reactions are mixed. Some observers think the study is “very exciting“; others are a bit more skeptical.

    Hmm, so there IS a scientific explanation for this! Interesting. Although, I’m a girl seeking answers to why women can’t seem to shut their mouths. I work with women who never stop yapping, have friends who will just talking endlessly…and can’t help but see this trend much more with women than with men. I prefer hanging out with men because they just chill out and are easier to have conversations with. Women seem to talk AT people instead of to them. I think they all like to hear the sound of their own voices. It’s weird. But am glad I was born without this abundance of ‘talk protein’!
