This is Scientific Americans' 60-second science. I'm Erica Barris. Got a minute?

If you're a senior citizen, music in the background may be distracting. But for younger people,

experts at multitasking, it's apparently no big deal. That's according to a study in the journal

Gerontologist. Researchers recruited 103 people, half between the ages

of 18 and 30, the other is between 60 and 75. The volunteers then took part in memorization

exercises and a drill where they had to quickly match a photo of a face with the same face in an array

of unfamiliar faces. Some participants did the exercises in silence.

Others perform the tasks while listening to white noise or instrumental jazz, blues, classical,

and electronic music.

Across age groups, the consensus was that the background sound was distracting.

But only older people's performance suffered when the noise was present.

For example, older folks who did the face matching with music playing remember 10% fewer faces.

The result matches up with the theory that the elderly are less able to filter out what's called distracting task irrelevant information.

In this case, the distracting info might have interfered with them storing the facial image in the first place,

much less impeding their ability to remember it a short while later.

Thanks for the minute. For Scientific American's 60 Second Science, I'm Erica Barris.
