Listening 1 Comprehension Questions
Comprehension Questions • What is the passage about? Try to explain in 10 words or less. • How effective is a polygraph? • How effective is fMRI? • Which does the speaker think is a more effective, a polygraph or fMRI? • Given the effectiveness of both methods, where do you think they should and should not be used?
2010FHSLecture2clip12 • The polygraph machine, the old fashioned lie detector, which measures physical reactions related to anxiety, so it measures your heart rate, your blood pressure, the sweatiness of your palms, how often you're breathing, how quickly you're breathing. It's been around for over eighty years, there aren't actually very many good, rigorous studies of it, but our National Academy of Sciences did a big report on it seven years, six years ago. And they concluded from the handful of really good studies that in laboratory settings, the polygraph seemed to be accurate about seventy five to eighty percent of the time. Now, that's in laboratory settings. We don't know how well it works in the field, in the real world. The fMRI people will claim seventy to ninety percent effectiveness in the lab. I think there's some problems with that data, but again, like polygraph, we don't know how good it is outside the lab.
