3. All of the following information could be used to help determine a person’s stage of sleep EXCEPT:

4. A researcher studying young adults’ sleep habits is exploring the impact of disrupting all REM sleep sessions during one night’s sleep. Using an electroencephalogram (EEG) she will monitor participants’ brain waves and body movements to determine when they are entering REM sleep. She can expect to wake the participants up approximately _____ during the night.

5. Sanji is taking an introductory psychology class and is learning about sleep patterns across the lifespan. He was not surprised to learn that as we age we need _____ hours of sleep.

According to one theory, narcolepsy symptoms like cataplexy and sleep paralysis indicate that the person is falling into REM sleep in the midst of wakefulness. If Matt were hooked up to an electroencephalogram (EEG) throughout the day, what type of brain waves might be indicative of these types of symptoms?
