It's long been known that girls develop superior language abilities earlier than boys, but until now, no one has any scientific proof.
Now, researchers at Northwestern University and the University of Haifa got the biological proof:
... areas of the brain associated with language work harder in girls than in boys during language tasks, and that boys and girls rely on different parts of the brain when performing these tasks.
"Our findings -- which suggest that language processing is more sensory in boys and more abstract in girls -- could have major implications for teaching children and even provide support for advocates of single sex classrooms," said Douglas D. Burman, research associate in Northwestern's Roxelyn and Richard Pepper Department of Communication Sciences and Disorders.
