Refer tо the reseаrch study belоw tо аnswer questions 7-12. Dr. Rem studies sleep аnd sleep disorders. She is curious as to whether falling asleep in front of a television set causes people to fall asleep more slowly than falling asleep without watching TV. She recruits a sample of 60 women and creates three conditions. All participants come to the sleep lab for three nights in a row and experience all three conditions. In the first condition (A), participants fall asleep in front of a television that is off. In the second condition (B), participants fall asleep in front of a television that is turned on to a 24-hour news channel. In the third condition (C), participants fall asleep in front of a television that is turned on to the same 24-hour news channel but is muted. Participants sleep in the same bed each night. With the use of an electroencephalograph (EEG; a physiological measure that measures electrical activity in the brain), the researcher measures how long it takes participants to fall asleep each night. How does this experiment enable researchers to establish temporal precedence?
