Scientists at the Chinese University of Hong Kong asked 63 people aged between 19 and 28 to find a shape on a computer screen full of similar targets that were changing colour.
In some tests the researchers also played sounds which made the target pop out from the cluttered display. The participants who multi-tasked the most in their everyday lives were more successful at spotting the target than others when the tone was played.
The researchers said that their ability to routinely take in information from different sources meant they had no trouble dealing with the unexpected sound, according to the Mail Friday.
