COLLEGE PARK, Md. (WUSA9) -- For years women have been complaining that men aren't as well versed in the communication department as women. Apparently science may have something to do with this phenomenon.
Researchers at the University of Maryland School of Medicine published findings on Wednesday in The Journal of Neuroscience that shows women have the biological makeup to talk more than men thanks to heightened levels of a certain protein, FOXP2, linked to speech and language development in humans.
In the study conducted by J. Michael Bowers, Margaret McCarthy, and their colleagues at the University of Maryland School of Medicine, levels of the FOXP2 protein were analyzed in the brains of four-day-old female and male rats before testing on humans to find communication differences between the sexes.
ScienceNOW's Michael Balter reported that after studying rats, the researchers conducted a small study on children aged four to five years old who had died in accidents less than a day before. This study showed 30% more FOXP2 protein in the brains of the girls as compared with the boys.
University of Maryland researcher, Margaret McCarthy, said in the published report that this study is one of the first of its kind.
"This study is one of the first to report a sex difference in the expression of a language-associated protein in humans or animals," McCarthy said. "The findings raise the possibility that sex differences in brain and behavior are more pervasive and established earlier than previously appreciated."
Through this study, University of Maryland researchers found that a heightened level of FOXP2 protein in the brain has a direct correlation with better communication skills thereby solidifying the fact that women are genetically predisposed to be better communicators than men.
