Research indicates that people who like to multitask:

A) actually perform worse than low multitaskers on tests that measured their abilities to concentrate.
B) perform better than low multitaskers on tests that measured their abilities to concentrate.
C) have more efficient brains.
D) tend to have better recall for words they learn while simultaneously doing a second task.

Answer: A
Rationale: It turns out that participants in one study who were more likely to multitask did worse on cognitive tests than those who tended not to multitask. These high multitaskers were easily distracted by irrelevant information and actually performed worse than low multitaskers when it came to switching from one task to another.
