Multitaskers:
- Did a significantly worse job filtering out the irrelevant information.
- Took longer than non-multitaskers to switch among tasks.
- Less efficient at juggling problems.
- Tended to search for new information rather than accept a reward for putting older, more valuable information to work.
- Process visual and auditory input less efficiently.
- Become reliant on more a more simplistic, and often inferior, thought process, and can thus fall prey to perceptual decoys.
Maybe multitasking gives the illusion of productivity without achieving higher volume...
