问题 单项选择题

阅读以下文字,完成以下问题。
说谎者控制不了脑波变化,谎话逃不出脑波监测。传统的测谎仪和FMRI图像测试结果有明显不同,也表明了如此复杂的说谎过程用传统测谎仪进行单一的生理指标判定并不科学。利用磁共振技术在今天可以辨别谁在撒谎,谁是说真话。
不过,功能性磁共振成像测谎也并非全能,有着致命的弱点。沈政告诉记者,这一技术只记录说谎后大脑变化的最终结果,然而神经活动却在瞬间完成,说谎也不例外。功能性核磁共振监测的血氧含量是在大脑完成说谎以后的3-6秒发生明显变化,那时,神经活动已经结束。因此,监测到的是心理括动的一个最终结果,而不是活动过程。
不过,与之相比,还有另外一个办法,“说谎时,脑波会发生变化,脑波的变化是说谎者控制不了的。”沈政说。
这个办法被叫做脑事件相关电位。据沈政介绍,这种办法记录的是脑波的变化,而且时间[ ]率非常精细,到了毫秒数量级的脑信号变化,每一毫秒的大脑变化都能够被记录下来。不过,这种方法的空间定位却较功能性磁共振成像测谎差,它不能够准确地记录哪些脑区结构在撒谎过程中发生了变化。
“兼具这两种技术的测谎,将是比较理想的。”沈政告诉记者,目前国际上已经有先进的国家将这两项技术结合起来,只是还没有同时用于测谎。这两项技术的结合运用,将是脑认知科学上最热的课题。
在美国费城Temple大学医学院功能性大脑影像中心主任斯考脱发罗所进行的实验中,就有人成功地通过了传统的测谎仪,而没被测试出来。有专家认为,在今天测谎仪面临巨大争议时,FMRI有望成为一种新型的测谎仪而介入司法活动中。
不过,北京大学心理系教授、博士生导师沈政认为,要使功能性磁共振成像测谎得到普遍、广泛地应用,还需要相当长的时间。
一方面,功能性磁共振成像测谎的设备非常昂贵,一套设备价值200多万美元;另一方面,对实验室的条件和操作人员的要求都非常高。这样的成本,无疑是推广、普及该项技术的一大障碍。
相对而言,脑事件相关电位的测谎较为容易一些。这项技术实施条件并不是很苛刻,成本较低,同时还能监测到大脑内部活动,克服传统测谎仪的弊端。专家预测,这项技术很快即可得到广泛应用。
测谎,是对谎言的鉴别活动。
自1895年意大利犯罪学家朗布罗梭首先使用“测谎仪”从事犯罪侦查以来,测谎技术的发展迄今已有100余年历史。我国自1991年研制出第一台“测谎仪”以来也有10年的历史了。
应用测谎技术,使世界各国的犯罪调查技术向前迈进了一大步,由以往只对物的鉴识,进而为对人的鉴识,成为世界侦查史上一大突破。
不过传统的测谎技术仅是对生理指标进行分析比较,因此遭到不少专家的质疑。人们正期待着一种新的、更为科学的测谎仪器面世。

下列对功能性磁共振成像测谎的表述不正确的一项是( )。

A.功能性磁共振成像测谎也并非全能,有着致命的弱点,即只能记录说谎后大脑变化的最终结果

B.传统测谎仪进行单一的生理指标判定并不科学。但利用磁共振技术在今天可以辨别谁在撒谎,谁是说真话

C.自1895年意大利犯罪学家朗布罗梭首先使用“功能性磁共振成像测谎”从事犯罪侦查以来,测谎技术的发展迄今已有100余年历史

D.功能性磁共振成像测谎的设备非常昂贵,对实验室的条件和操作人员的要求都非常高。这是推广、普及该项技术的一大障碍

答案

参考答案:C

One morning, Charley, a little green frog, was sitting in a pond by the side of the road.

Wanda, the neighborhood witch(女巫), was walking along the road. She was a good witch and dreamt to become a fairy godmother who can save people from trouble with magic powers. Wanda had been learning fairy godmother magic for 103 years. That morning, she decided to try the magic she had learned and bring happiness to others.

Seeing Wanda, Charley cried, “Hi, Wanda.”

“Hi, Charley,” replied Wanda, “I have a surprise for you.”

Then, Wanda waved her wand(魔杖), said a magic word, and Charley turned into a prince!

When Charley-turned-prince looked at himself in the water, he cried, “Hey! You turned me into a prince! It’s a surprise all right, but I don’t want to be a prince! Change me back right now!”

“Oh, dear,” Wanda said. “You shouted so loud that I forgot the way to change you back. But who wouldn’t rather be a prince?”

“I wouldn’t!” cried Charley. “I want to be a frog!” He stuck out his tongue, missing a bug (虫子)flying by the end of his nose. “Look at that, Wanda! I was a good fly catcher. But now, this tongue is too short! Please change me back!”

“I can’t, Charley. But you’ll learn to be happy as a prince.” She waved her wand, and suddenly a castle appeared. Out of the castle dozens of musicians were playing various instruments. “Charley! You’ll have servants, eat delicious foods, and you can sing and dance and snap fingers(弹响指).”

“No!” Charley interrupted, “I don’t want all these! I want bugs!” Charley cried. “I don’t want to sing and dance! And why would I do something as silly as snapping my fingers?”

“Snapping fingers!” cried out Wanda. “That’s what I forgot!” She snapped her fingers, cried “Upsi-doodle!” and the castle and musicians disappeared and the prince became a little green frog.”

Charley looked at himself in the water. “ You did it, Wanda. Oh, happy day! I’m a frog.”

“I must apologize, Charley,” Wanda said, “You are a happy frog. I should know this a moment ago.”
