- A time spent, mainly during the night, when the person is less reactive to external stimuli
- A 4-stage process by which dreams are stored in the memory bank
3. Different states of alertness cause different waves of electrical activity in the brain - which of the following is true?
- Alert= Sleep spindles, Relaxed= Alpha, Stage 1 = sleep spindles, Stage 2=delta, Stages 3 and 4= theta
- Alert = Alpha, Relaxed = Delta, Sleep stage 1 =Theta, Sleep stage 2 = delta, Stages 3 and 4 = sleep spindles
- Alert= Beta, Relaxed= Alpha, Sleep stage 1 = theta, Stage 2= sleep spindles, stages 3 and 4 = delta
- Alert =Beta, Relaxed = Delta, Sleep stage 1 = sleep spindles, stage 2= theta and stages 3 and 4 = Delta
4. Which of the following shows the correct magnitude of the electrical waves exhibited during sleep?
- Theta (3.5-7.5), sleep spindles 1-2s burst of 12-14 H
- Theta (3.5-7.5), sleep spindles 1-2s burst of 20-24 Hz
- Theta (8.5-12.5), sleep spindles 1-2s burst of 20-24 H
5. What does the restoration model of sleep state?
- That sleep's purpose is to repair physical damage to the body and aging cells, and to return the body to a level homeostatic state
