Which of the following is true about multitasking?
A) The brain is not designed for multitasking.
B) The brain is designed to effectively do more than one cognitive task at a time, provided the two tasks can be processed by the same brain structure.
C) The brain is designed to effectively do more than one cognitive task at a time, provided the two tasks can be processed by different brain structures.
D) Compared to low multitaskers, people who like to multi-task have brains which make them more efficient at it.
Answer: C
Rationale: Psychologists have also found that the brain is designed to effectively do more than one cognitive task at a time, provided the two tasks can be processed by different brain structures. Thus, the brain is able to multitask to a point, but it is important to avoid believing that just because someone likes to multitask that they are a good multitasker. Research shows just the opposite.
