Study Notes
Stages of Sleep
- N1 (Stage 1): light sleep, characterized by hypnogogic images, hypnic jerk, and sleep spindles
- N2 (Stage 2): body temperature, breathing, and heart rate decrease, sleep spindles occur
- N3 (Stages 3 and 4): deep sleep, delta waves, growth hormones released, hard to wake up, body at lowest level of functioning
- REM (Rapid Eye Movement): eyes move under eyelids, rest of body is still, 90% of dreaming occurs, EEG similar to awake individual, also referred to as paradoxical sleep
Sleep Disorders
- Insomnia: inability to get to sleep, stay asleep, or get good quality sleep, caused by psychological (worrying, anxiety) or physiological (caffeine, indigestion, pain) factors
- Narcolepsy: disease marked by sudden and irresistible onsets of sleep during normal waking periods, excessive daytime sleepiness, affecting 1 in every 2,000 persons, characterized by sudden REM attacks and cataplexy (sudden loss of muscle tone)
Dreaming Theories
- Freudian interpretation: dreams have hidden, symbolic meaning, reflecting unconscious desires and conflicts
- Problem-solving view (Cartwright): dreams provide opportunity to work through everyday problems and emotional issues, contribute to improvements in mood when people awaken
- Activation-Synthesis Theory: dreams are products of activity in the pons, random signals sent to cortex, brain synthesizes explanation from memories and stored information
- Activation-Information-mode (AIM) Model: dreams may have more meaning than previously thought, information accessed during waking hours influences synthesis of dreams
What Do People Dream About?
- Cognitive Theory of Dreaming: most dreams reflect events that occur in everyday life
- Gender differences: men dream of other males more often, women dream of males and females equally, cultural and genetic influences contribute to these differences
- Sexual content is common in dreams
Hypnosis
- HYPNOSIS CAN: give increased strength, reduce pain, alter sensory impressions, help people relax
- HYPNOSIS CANNOT: reliably enhance memory, regress people to an earlier age or life
- Theories of Hypnosis: works only on immediate consciousness, while hidden "observer" is aware of everything going on, allows for dissociation from pain
