Multitasking: Not Recommended

Researchers at the Federal Aviation Administration and the University of Michigan, Ann Arbor found that while doing multiple tasks at once may appear to be more efficient it actually is more time consuming and in some cases poses health risks.

Four groups of young adults participated in four experiments. They were all asked to carry out a series of tasks and switch between different tasks, some complicated, such as solving a math problem, and others easier and more familiar, such as identifying a geometric shape. A
participant's performance speed was measured as the tasks were carried out.

The findings: human capacity for multitasking decidely has its limits. Participants lost time in performance speed when switching tasks and they lost more time as the task became more complex.
