Psychologist George Spilich in Maryland College decided to find out whether, as many smokers say, smoking helps them to "think and concentrate". 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(试验对象) sat before a computer screen and pressed a key as soon as he or she recognized a target letter among a group of 96. In this simple test, smokers, deprived smokers and non smokers performed equally well.
The next test was more complex, requiring all to scan sequences of 20 identical letters and respond the instant one of the letters transformed into a different one. Non-smokers were the fast, but under the stimulation of nicotine(尼古丁), active smokers were faster than deprived smokers.
In the third test of short-term memory, non-smokers made the fewest errors, but deprived smokers committed fewer errors than active smokers.
The fourth test required people to read a passage, then answer questions about it. Nonsmokers remembered 19 percent more of the most important information than active smokers, and deprived smokers bested those who had smoked a cigarette just before testing. Active smokers tended not only to have poorer memories but also bad trouble separating important information from insignificant details.
"As our tests became more complex," sums up Spilich, "non-smokers performed better than smokers by wider and wider margins." He predicts, "Smokers might perform adequately at many jobs until they got complicated. A smoking airline pilot could fly adequately if no problems arose, but if something went wrong, smoking might damage his mental capacity."
选项
A、to test whether smoking has a positive effect on the mental capacity of smokers
B、to show how smoking damages people’s mental capacity
C、to prove the smoking affects people’s regular performance
D、to find out whether smoking helps people’s short-term memory
答案
A
解析
题干意为“George Spilich所做实验的目的是…”。该题为细节题。由第一段中"...decided to find out whether,as many smokers say, smoking helps them to ’think and concentrate’"可以看出目的是要确定是否吸烟能帮助他们思考和集中精力,是否对烟民的思维能力有益。
