The myth of multitasking

1.Why is multitasking considered by many psychologists to be a myth?

Multitasking is considered to be a myth because in reality we cant do two things at the same time . The only thing we can do is to change of task so fast that we think that we are multitasking . One example is texting while speaking , you are going to text or talk in stead because you are gooing to think in one better.

2.To what does the term "response selection bottleneck" refer?

Marois found evidence of a “response selection bottleneck” that occurs when the brain is forced to respond to several stimuli at once. As a result, task-switching leads to time lost as the brain determines which task to perform.

3.David Meyer has found that multitasking contributes to the release of stress hormones and adrenaline . Why is this important? 

This is important to know because stress hormones and adrenaline can cause long-term health problems if not controlled, and contributes to the loss of short-term memory

4.Explain what Russel Podrack found regarding multitasking.

His research demonstrates that people use different areas of the brain for learning and storing new information when they are distracted. Brain scans of people who are distracted or multitasking show activity in the striatum, a region of the brain involved in learning new skills . Brain scans of people who are not distracted show activity in the hippocampus, a region involved in storing and recalling information. 

5. What does  the author conclude could happen to our culture as a result of increased multitasking?

With crumbs of attention rationed out among many competing tasks . Their culture may gain in information, but it will surely weaken in wisdom.
