Ever notice how slow interstate speeds like 55mph just cause a person to drift
off, pay attention to crap on the side of the road, not judge things well?

Study Finds Kids Can't Hit Slow Pitches

You're throwing a ball for a toddler to smack with a plastic bat. You toss it
gently, slowly, to make it easier. He just can't hit it.

It's because you throw too slowly, a new study finds.

Kids' brains aren't wired for slow motion.

"When you throw something slowly to a child, you think you're doing them a favor
by trying to be helpful," said Terri Lewis, professor of psychology at McMaster
University. "Slow balls actually appear stationary to a child."

Add a little speed to the pitch, Lewis and her colleagues suggest, and the child
is able to judge its speed more accurately.

"Our brain has very few neurons that deal specifically with slow motion and many
neurons that deal with faster motion," Lewis said. "Even adults are worse at slow
speeds than they are at faster speeds."

Kids' neurons are immature, making the task even more challenging for them.

The study will be detailed in the July issue of Vision Research.
