Online test calculates brain speed

As some researchers examine brain functions with advanced imaging technology, other scientists are measuring brain speed with the click of a mouse.

San Francisco-based Posit Science unveiled a program in recent weeks that tests how fast a person's brain can process information, based on his or her hearing speed.

"Auditory processing speed is important because much of the information we receive each day is communicated through sound--especially speech," according to Posit Science, which has developed software that promotes brain fitness. "The faster we can take in information accurately, the better we can keep up with, respond to and remember what we hear."

The 10-minute online test, at the company's Web site, measures how fast and accurately the test-taker can detect different sounds, by having the test-taker click on arrows. Once finished, the test-taker will receive a measurement of his or her brain speed, down to the millisecond.
