Mr. Faugel was convinced that student nervousness had affected their scores; to reduce the anxiety of these students who had already been tested, he gave 22 of them a beta blocker before readministration of the test. Their scores improved significantly. The other 8 students (who did not receive the beta blockers) improved only slightly. Second-time test-takers nationwide had average improvements which were similar to those in Faugel’s non-beta blocker group. Beta blockers are prescription drugs which have been around for 25 years. These medications, which interfere with the effects of adrenalin, have been used for heart conditions and for minor stress such as stage fright. Now they are used for test anxiety. These drags seem to help test-takers who have low scores because of test fright, but not those who do not know the material. Since there can be side effects from these beta blockers, physicians are not ready to prescribe them routinely for all test-takers. [br] Faugel’s research showed that beta blockers given to his sample ______.
选项
A、increased scores less than the national average
B、increased scores the same as the national average
C、decreased scores
D、increased scores much more than the national average
答案
D
解析
从文中前四句得知,“将30名参加过测试的学生分成实验组和对比组,让实验组的22名学生服用了β-受体阻滞药(而8名对比组的学生没有服用),然后又对他们进行次测试,结果服药的学生成绩提高显著,没服药的学生成绩只略有提高,全国范围内的实验结果也证明第二次参加测试的学生成绩均有提高,与没服药的学生类似。”因此选项D.“Faugel的研究表明服药学生的成绩比全国范围内的实验结果中(没服药的)学生成绩高出许多。”是答案。
