18、(分散注意力)？Does the mere possibility that a phone call or an email will soon arrive drain your brain power？And does distraction matter？Do interruptions make us dumber？Quite a bit.Theres a lot of debate among brain researchers about the impact of small things on our brains.Most discussion has focused on
19、 the deleterious effect of multitasking.Early results show what most of us know implicitly：if you do two things at once，both suffer.We decided to investigate further，and asked Alessandro Acquisti，a professor of information technology，and the psychologist Eyal Peer at Carnegie Mellon to design an exp

24、 to focus on the questions.Again，the Interrupted group underperformed the Control group，but this time they closed the gap greatly，to a respectable 14 percent.Dr.Peer said this suggested that people who experience an interruption，and expect another，can learn to improve the way that they deal with it.
25、But among the On High Alert group，there was a twist.Those who were warned of an interruption that never came improved by a huge 43 percent，and even outperformed the Control group takers who were left alone.This unexpected finding required further research，but Dr.Peer thought there was a simple expla
