SLEEP DEPRIVATION • Study on college students (Pilcher & Walters, 1997) • Participants complete cognitive test after either 8 hours of sleep or 24 hour sleep deprivation • All subjects asked to rate their effort, concentration, and estimated performance on the task Results: although sleep deprived subjects performed worse on the task, they rated their effort, concentration, and performance higher than the sleep group!

SLEEP DISORDERS • Narcolepsy – disease marked by sudden and irresistible onsets of sleep

SLEEP DISORDERS • Narcolepsy – disease marked by sudden and irresistible onsets of sleep during normal waking periods • wakefulness to REM sleep for about 10 -20 minutes • cause unknown

SLEEP DISORDERS • Insomnia: • difficulty falling asleep, remaining asleep and persistent early-morning wakening

SLEEP DISORDERS • Insomnia: • difficulty falling asleep, remaining asleep and persistent early-morning wakening • Prevalence: • 15% adults report severe insomnia • 15% adults report mild/occasional • Increases with age “Sleep-state-misperception”: • 5% insomniacs show sound sleep patterns

SLEEP DISORDERS • Sleep apnea – frequent, temporary halt of breathing for 15 -60

SLEEP DISORDERS • Sleep apnea – frequent, temporary halt of breathing for 15 -60 seconds while sleeping • prevalent in 5% men 40 -60 yrs old • CNS ceases to function, causing diaphragm to stop moving or loss of muscle tone in tongue and throat

SLEEP DISORDERS (CONTINUED) • Nightmares – anxiety-arousing dreams, lead to awakening from REM sleep

SLEEP DISORDERS (CONTINUED) • Nightmares – anxiety-arousing dreams, lead to awakening from REM sleep • • correlation between stress and nightmares prevalent in 10% adults persistent nightmares in children may reflect emotional disturbance • Night terrors – abrupt awakenings from Non. REM sleep accompanied by intense arousal and panic - most common in children 3 -8 - not indicative of emotional disturbance

DREAM THEORY • What is the importance of dreams? What meaning, if any, do you attach to dreams? • Read qualitative recaps of dreams provided • Are these dreams more than the “nonsensical noise of a restless brain stem” as one researcher described them?

 • Ed was 57 when his wife Mary died of cancer after 32

• Ed was 57 when his wife Mary died of cancer after 32 years of marriage. When he dreamed about her shortly after her death in June of 1980, he experienced it as a precious moment of being with her, and wrote it down. Two months later, he dreamed about her again, and wrote that one down too. Soon he found himself writing down every dream in which she appeared. In the first 22 years after her death, he wrote down 143 dreams -- as few as two in one year, as many as 14 in another. The dreams have much in common with other dreams of deceased loved ones. In a few early dreams she comes back to life or provides him with reassurance that she is doing well. Many dreams are about the time of her final illness, but others are about their earlier life together, providing a portrait of a marriage. • Bea's vivid dream reports from age 14 to 16 provide one of the longest and most detailed dream journals we have from a young teenager. • Jasmine is a young woman who recorded hundreds of her dreams from age 14 to 27. In addition to the young age at which Jasmine started keeping a dream journal, there is another unique feature to this series: the

WHY DO WE DREAM? 1. Wish Fulfillment: Freud suggested the dreams provide a psychic safety valve to discharge unacceptable feelings. The dream’s manifest (actual) content may also have symbolic meanings (latent content) that signify our unacceptable feelings. 2. Information Processing: Dreams may help sift, sort, and fix day’s experiences in our memories.

WHY DO WE DREAM? 3. Activation-Synthesis Theory: Suggests that in the brain engages in a lot of neural activity that is random. Dreams make sense of this activity. All dream researchers believe we need REM sleep. When deprived of REM sleep, and then allowed to sleep, we show increased REM sleep called REM Rebound.

WHAT DO WE DREAM? 1. Negative Emotional Content: Eight out of 10 dreams have negative emotional content. 2. Failure Dreams: People commonly dream about failure, being attacked, pursued, rejected or struck with misfortune. 3. Sexual Dreams: Contrary to our thinking sexual dreams are sparse. Sexual dreams in men are 1 in 10; and in women 1 in 30.
