Few drive well while yakking on cell phones

sured in four areasbraking reaction time, following distance, memory, and math execution.

As expected, results showed that for the group, performance suffered across the board while driving and talking on a hands-free cell phone.

For those who were not supertaskers and who talked on a cell phone while driving the simulators, it took 20 percent longer to hit the brakes when needed and following distances increased 30 percent as the drivers failed to keep pace with simulated traffic while driving. Memory performance declined 11 percent, and the ability to do math problems fell 3 percent.

However, when supertaskers talked while driving, they displayed no change in their normal braking times, following distances or math ability, and their memory abilities actually improved 3 percent.

The results are in line with Strayer's prior studies showing that driving performance routinely declines under "dual-task conditions" namely talking on a cell phone while driving and is comparable to the impairment seen in drunken drivers.

Yet contrary to current understanding in this area, the small number of supertaskers showed no impairment on the measurements of either driving or cell conversation when in combination. Further, researchers found that these individuals' performance even on the single tasks was markedly better than the control group.

"There is clearly something special about the supertaskers," says Strayer. "Why can they do something that most of us cannot? Psychologists may need to rethink what they know about multitasking in light of this new evidence. We may learn from these very rare individuals that the multitasking regions of the brain are different and that there may be a genetic basis for this difference. That is very exciting. Stay tuned."

Watson and Strayer are now studying expert fighter pilots under the assumption that those who can pilot a jet aircraft are also likely to have extraordina
