A group of researchers is planning an experiment to test the hypothesis that sleep deprivation decreases memory retention. All participants will have a practice session in which they memorize words. That night they will sleep in a monitored lab for a specified time that depends on their group. T each participant will be tested on how many words they remember from the practice session. The researchers are deciding what conditions they should manipulate for the experimental group. Q3.7. The table below shows conditions for the control group and three possible experimenta groups. Which experimental group should the researchers use to compare to the control gro in order to test their hypothesis? Number of hours of sleep Days between practice and testing Length of practice session Control Group 8 hours 1 day 30 minutes Experimental Group 1 4 hours 3 days 30 minutes Experimental Group 2 8 hours 1 day 45 minutes Experimental group 1 Experimental group 2 Experimental group 3 O None of the experimental groups are appropriate for testing their hypothesis. Experimental Group 3 4 hours 1 day 30 minutes

Direction: Read carefully the essay and get ready to answer the following motive questions below. Zap the Zombie Syndrome by Jennifer Tufts “Early to bed, early to rise; makes a man healthy, wealthy, and wise. According to the recent studies at the University of California’s Department of Psychiatry, this is not true for teenagers. The study suggests that most teens have some form of Delayed Sleep Syndrome, which means REM (Rapid Eye Movement) takes longer to set in. Since it is during a series of five to eight REMS or dream sleep, that the body is truly relaxed, students today feel most rested if they go to sleep late at night and don’t get up until late morning the next day. Unfortunately, nowhere in the foreseeable future are schools going to change the long-treasured 8:00 A. M. tardy time to around noon. For now, students are forced to seek other ways to overcome the mid-morning nap in government and the afternoon slump in pre- calculus. A healthy diet can be the first way to…

Group of answer choices H.M. had profound anterograde amnesia H.M.’s non-declarative memory was intact. H.M. was unable to remember clinicians he met after the surgery, even though they worked with him for many years.
