Variations of Consciousness ASSIGNMENT a. Study text Chapter 5 (174-189, 199-208). b. Read Course Guide Reading 10 – Managing Sleep Deprivation c. Complete Concept Checks 5.1 (pg 181). d. Review Questions: Chapter 5 practice test questions 4,5,11-14 (pg 213). e. Answer IPO 10. LESSON OBJECTIVE 10.1. Explain the effects of disrupting circadian rhythms and sleep deprivation. 10.2 Design a plan to minimize the impact of sleep deprivation and circadian rhythm disruption 10.3 Describe the effects of drugs and alcohol on neurotransmissions. PERFORMANCE OBJECTIVES 10-1. Describe circadian rhythms. Circadian rhythms : the 24-hour biological cycles found in humans and many other species; regulate sleep 10-2. Explain the effects of disrupting circadian rhythms. Getting out of sync with you circadian rhythm causes jet lag . Going to bed at the wrong time causes difficulty falling asleep and poor quality of sleep. Studies have shown that melatonin can reduce the effects of jet lag by helping travelers realign their biological clocks. 10-3. Differentiate REM from non-REM sleep. REM- Rapid Eye Movement sleep: deep stave of sleep, marked by irregular breathing and pulse rate; EEG activity is dominated by high-frequency beta waves that resemnle those observed when people are awake REM Sleep is a relatively deep stave of sleep marked by rapid eye movements, high- frequency, low-amplitude brain waves and vivid dreaming. Non-REM sleep: consists of sleep stages 1 through 4, which are marked by an absence of rapid eye movements, relatively little dreaming, and varied EEG activity 10-4. Identify the typical sleep requirements for young adults. 10 10 L E S S O N

Typically spend about 20% of sleep time in the slow-wave sleep and 20% in REM sleep 10-5. Summarize how age and culture affect the need for sleep. As a person ages, the percentage of time in slow wave sleep declines and the percentage in stage 1 increases. This shift could possibly be due to increased frequency in nighttime awakenings. Total sleep increases with age however. Sleep does not appear to vary very much across cultures. Sleep practices do vary. Ex) Eastern civilizations practice co-sleeping , parents and children sleeping together, which is discouraged in Western culture. Napping practices vary across cultures as well. Ex) siestas are naps during the hottest part of the day in tropical cultures. 10-6. Explain the effects of sleep deprivation. Sleep restriction: With sleep restriction, the negative effects are greatest when subjects are asked to work on long-lasting, difficult, or monotonous tasks or when sleep was restricted to 6 hours or fewer each night. In general, sleep restriction can impair individuals’ attention, reaction time, motor coordination, and decision making and have negative effects on endocrine and immune system functioning.
