RESEARCH STUDY 4.1 Dr. Kline Is Planning on Conducting a Study Next Semester

RESEARCH STUDY 4.1
Dr. Kline is planning on conducting a study next semester. He is curious as to whether sleep deprivation is associated with poorer cognitive performance. For example, if you sleep poorly the night before a big exam, will you do worse? Dr. Kline is especially curious about selective sleep deprivation, where people are kept from entering R.E.M. (rapid eye movement) sleep. Using an electroencephalograph (EEG) to monitor brain waves, he plans to let participants sleep until they enter R.E.M. sleep and then he will wake them. After 1 minute of being awake, he plans to let them return to sleep. As they enter R.E.M. sleep again, he wakes them up again and follows the same procedure. He plans to do this through the entire 8-hour sleep session. The following morning, participants will be asked to take a sample SAT test.
-Refer to Research Study 4.1 above to answer the following question. Dr.Kline plans to use deception in his study and is thinking about a debriefing session.Which of the following is true of the debriefing?

A) Dr. Kline only needs to invite participants who were troubled by the study to the debriefing session.
B) Because his study has potential medical applications, the use of a debriefing session is optional.
C) During the debriefing, Dr. Kline only needs to tell the participants that there was deception.
D) Participants must be told the reasons for the deception.
E) All of the above are true.
