Researchers report that doing two or more things at once may decrease efficiency and actually take extra time switching from one task to another. In the most severe cases, it can even mean the difference between life and death.
"People get tired when they’re trying to multitask(多任务化) ," and in some cases a person could ultimately create more work for himself, according to one of the lead authors, David Meyer, of the university’s psychology department.
The researchers found that time was lost in just switching from one task to another, and that time costs increased with the complexity of the tasks. The subjects got "up to speed" faster when they switched to tasks that were familiar.
When people, say, juggle browsing the Web and using other computer programs, or talk on the phone while driving, they are using their "executive control" processes in their brain, the re searchers said. Those processes can be likened to the mental CEO, the part of the brain associated with establishing priorities among tasks and allocating resources to them.
A mere half second of time lost to task switching can mean the difference between life and death for a driver using a cell phone, Meyer said.
The authors say the research should make employers and employees think twice before implementing multitasking.
