The low percentage of women in science ，technology，engineering，and mathematics(STEM) careers is often attributed (归因于) to men being believed to be better at the sort of thinking those fields require. Though studies have debunked the view,they have largely been based on results acquired from various several standardized tests. Now, researchers from Pennsylvania' S Carnegie Mellon University have found evidence that is hard to overlook; MRI (磁共振成像) proves that young girls and boys use the same mechanisms and networks in the brain to solve math problems.
The groundbreaking study to evaluate the biological gender differences in the math talent of young children was led by the university' s professor of neuroscience, Jessica Cantlon. For their study ,the team selected 104 young children, between 3 and 10 years old, divided almost equally by gender. The scientists used a functional MRI to observe their brain activity as they engaged in math tasks. These included watching age appropriate educational videos and doing math exercises such as counting and addition,as well as reading for comparison.
“We looked at which areas of the brain respond more strongly to mathematics content in the videos and tasks, compared to non math content like reading or the alphabet, Cantlon said.“When we do that in lite girls, we see a particular network of the brain respond,and when we do that same analysis in boys, we see the exact same regions.”
So why do girls and young women tend to avoid math and STEM careers in general? Cantlon thinks it may be rooted in social and cultural conventions. Previous studies have indicated that parents tend to spend more time with young boys in play that inspire spatial cognition (空间认知)-such as toys that involve learning number skills and shapes and solving puzzles. Educators were also observed to spend more time with boys during math class.

Rioghna and Hannah Pittock spent the first few minutes feeling sorry for themselves. Rioghna,a junior at Rochester Mayo High School, had spring sports to play.

Yesterday I went to buy an ice cream. As I was standing in the line, I saw a lady with her two kids. The boys want to have an ice cream. However, the mother, which happened to have no change on her, just bought one ice cream to the little boy. I noticed the older boy look a little sadly.
