Question

You see an advertisement for a method of learning a foreign language that seems simple—just put on a tape and fall asleep. The accompanying description cites proof that people can learn while asleep. Being a good psychological detective, what question would you ask about the offered proof?
A. Did the individuals actually dream about the foreign language?
B. What did the EEG indicate about the participants' level of sleep?
C. Did the researchers use only long sleepers who would spend more time with the tapes?
D. Were study breaks included in the tape to provide greater comprehension of the material?

Answer 1

Answer:

B. What did the EEG indicate about the participants' level of sleep?

Explanation:

This is the question that you would most likely ask about the offered proof. In order to truly know learn about the effectiveness of the method, we would have to know what the EEG indicated about the participants' level of sleep. Being critical about this kind of evidence will prevent us from falling prey to false adverstising and scams.
