Consciousness
our awareness of ourselves and our environment
Dual-processing
the principle that info is often simultaneously processed in separate conscious and unconscious tracks
Unconscious parallel processing
(being able to process several things at the same time)
conscious sequential processing
only able to process one thing at a time
Parallel processing
allows your mind to take care of routine business, such as following the path to get back home and in traffic, whereas sequential processing is skilled at solving new problems or engaging in activities that require your focused attention, such as a car spinning ahead of you in traffic
Selective attention
focusing your conscious awareness on a particular stimulus
Cocktail party effect
if you’re at a party and in a convo and you hear your name in another convo your attention will be immediately pulled to that convo instead of the one you’re already in
Inattentional blindness
failure to see objects when our attention is directed elsewhere
Circadian rhythm
24 hour biological cycle
Awake and alert
beta waves
Awake and relaxed
alpha waves
Stage 1 sleep
alpha and theta waves
light sleep; hallucinations like falling until you jerk may occur
AKA NREM-1
very brief
Stage 2 sleep
delta waves and K complexes
AKA NREM-2
Lasts about 20 minutes
Stage 3 sleep
delta waves
hard to wake them up; bedwetting occurs in this stage. This is considered deep sleep. Growth hormones are released in this stage.
As we get older, we need less growth hormone and there is less deep sleep
AKA NREM-3
lasts about 30 min
REM sleep
Rapid Eye Movement; brain waves look like person is fully awake and alert, but paradoxically, they are in a deep sleep (in fact, hard to awaken someone in this stage) and the muscles are paralyzed (if not, we might physically act out our dreams).
Happens about an hour after falling asleep
Beta waves again
About every half minute your eyes dart around your eyelids
Your genitals are aroused in this stage of sleep no matter what the dream is about
As the night goes on the rem periods get longer building up to about 40 min per cycle
