　　George Spilich at Washington College in Chestertown, Maryland, decided to find out whether, as many smokers say, smoking helps them to “think and fix their attention on (集中精力于)their work”. Spilich put young non－smokers, active smokers and smokers deprived(被剥夺)of cigarettes through a series of tests.

　　In the first test, each subject sat before a computer screen and pressed a key as soon as he or she recognized a certain letter among a grouping of 96. In this simple test, smokers, deprived smokers and non－smokers performed equally well. The next test was more difficult, requiring all to scan(扫描) groups of 20 letters and find the one of the letters changed into a different one. Non－smokers were faster, but under the stimulation(刺激)of nicotine, active smokers were faster than deprived smokers. In the third test of short－term memory, non－smokers made the fewest mistakes, but deprived smokers made fewer mistakes than active smokers. The fourth test required people to read a passage, then answer questions about it. Non－smokers remembered 19 percent more of the most important information than active smokers, and deprived smokers did better than those who had smoked a cigarette just before testing. Active smokers were likely not only to have poorer memories but also had trouble separating important information from unimportant details.
