Example Questions
Example Question #1 : States Of Consciousness
Gina is in the middle of her workday, she is fully focused and alert to the new information she is reviewing on her computer screen. After a while, she sits back in her chair and takes a few deep breaths with her eyes closed to relax. What of the following pairs of brain waves and corresponding hertz best identifies what Gina's brain is producing while concentrating and while at rest?
Beta 4-8 hertz and alpha 13-30 hertz
Alpha 13-30 hertz and alpha 8-13 hertz
Theta 4-8 hertz and beta 13-30 hertz
None of these
Beta 13-30 hertz and alpha 8-13 hertz
Beta 13-30 hertz and alpha 8-13 hertz
Beta brainwaves function at 13-30 hertz and they are associated with being alert, active, or concentrated. On the other hand, alpha brainwaves function at 8-13 hertz and are associated with daydreaming and more relaxed states of mind. Alpha waves are responsible for the calming feeling that one experiences when they close their eyes and take a few deep breaths.

NREM3
NREM2
REM
NREM1
All of these
REM

Example Question #4 : States Of Consciousness
On a normal night, a person goes through different stages of sleep. During which stage of sleep does a person experience twitches, hypnic jerks and hypnagogic hallucinations?
NREM3
None of these
REM
NREM2
NREM1
NREM1

This all occurs in the first stage of sleep, NREM 1.An easy way to remember this is to think if someone wakes you up shortly after you fall asleep. You may recall a vivid hallucination but you were not yet in REM sleep, the stage of dreams.
Example Question #5 : States Of Consciousness
On a normal night, a person goes through different stages of sleep. During which stage of sleep can delta waves be seen, the slowest of all sleep waves?
NREM1
None of these
REM
NREM3
NREM2
NREM3
During stage NREM 3 there are delta waves present on EEG. These are the slowest of all sleep brain waves and signifies the deepest, most restful stage of sleep.
