- Awareness of thoughts regarding the experience.
What was Sigmund Freud’s belief about consciousness?
There is an unconscious that drives a lot of behavior.
What does an EEG do?
Measure variations of consciousness through Brain Wave Activity.
What are the 4 different bands of Brain Wave Activity? (DEFINE EACH AND IN THE CORRECT ORDER)
Beta 15-30 Hz - Alert, problem-solving
Alpha 9-14 Hz - Resting and relaxation
Theta 4-8 Hz - Deep relaxation, low alertness, light sleep
Delta 1-3 Hz - Deep sleep

Explain Stages 1-5 of the Sleep Cycle, what REM is, and the order of the stages leading up to REM & what stage it occurs at.
Stage 1: Theta Waves are prominent (state of relaxation)
Stage 2: Sleep spindles are prominent (brief bursts of brain waves that happen during non-rapid eye movement (NREM) sleep)
Stage 3 & 4: Slow-wave sleep, moving into delta waves (1-3 Hz, getting into deep sleep)
Stages 1-4 are NREM
REM is Rapid-eye movement, a deeper sleep where dreams occur, also seen as the “5th” stage. Order is 1,2,3,4,3,2,1, 5 (kind of around where the 2nd stage should be)
Describe REM.
- A deeper sleep where dreams occur
- Very minimal bodily movement
- High Frequency BETA Waves: THIS IS WHY YOU DREAM (you’re technically alert)
-You should hit REM about 4 times.
What is sleep deprivation and what are the effects of Sleep Deprivation?
About 3-4 nights of little-to-no sleep.
- impaired attention
- reaction time slows
- cognitive speed slows
- Poor motor coordination & decision making
What health problems is sleep deprivation linked to?
Obesity, diabetes, hypertension, CHD, weakened immune system.
What is the most common type of sleep disorder?
Insomnia
What are the 3 identifiable patterns of insomnia?
- Struggling to fall asleep
- Struggling to stay asleep
- Waking up earlier than intended/desired.
