You're at the front lines shooting Nazis before they shoot you. Or you're a futuristic gladiator in a death match with robots.

"People that play these fast-paced games have better vision, better attention and better cognition," said Daphne Bavelier, an assistant professor in the department of brain and cognitive science at the University of Rochester.

Bavelier was a presenter at Games for Learning, a daylong symposium on the educational uses of video games and computer games.
