Psychology Flashcards
Sleep Unit!!
Consciousness
The individual awareness of your unique thoughts, memories, feelings,sensations, & environments.
- If you can describe something you are experiencing with words,then it is part of your consciousness
Factors into level of consciousness:
Activity, diet, sleep, drug/medication use, moon/emotion, environment(loud/quiet/hot/cold), amount of light, physical health, & mental health
N1
Only experience when we go from being awake to asleep.
Transition = wake to asleep
~ Hypinc jerk
~ Imagery, also called hypnagogic hallucinations
~ More like daydreams
~ Usually about 7 minutes, but could be shorter (other determining factors would cause that)
N2
Lighter stage of sleep, but harder to wake up
- Heart rate decrease
- Body temperature decrease
-Breathing slower/regular
- Muscles relax
N3
Slow-Wave Sleep (SWS)
Where brain activity is the slowest, big & slow waves.
- Blood pressure drops, breathing becomes slower, muscles relax, blood supply to the muscles increases, tissue growth & repairs, heartbeat decreases, & a lot of movement
~ Immune system
~ Slowest brain waves, hardest to waken, will be groggy, disoriented
~ Sleep walking & talking
REM
25% of the night, first occurs 90 minutes after asleep & reoccurs every 90 minutes, getting longer later in the night
- Rapid Eye Movement
~ Move back & forth under eyelids
~ Where most of our dreams happen
~ Muscle paralysis, body immobile & relaxed, voluntary movements are temporally paralyzed
~ Provides energy to the brain & body
~ Supports daytime performance
Circadian Rhythm
Our internal daily biological clock (approximately 24 hours)
Sleep/wake cycle
Jet Lag
Change in time zone & we have to adjust our biological clock.
- Sleep protects
(5 reasons that sleep exists)
Helps protects your species overall, helps us survive to a level
- Sleep helps us recoperate
(5 reasons that sleep exists)
Helps us restore the immune system & repair the brain tissue.
Sleeping a lot gives resting neurons times to repair themselves, while weakening unused connections.
- Restore & rebuild memories
(5 reasons that sleep exists)
Sleep consolidates our memories. Reactivates recent experiences stored in the hippocampus & shifts them for permanent storage elsewhere in the cortex.
COGNITIVE THINKING!!
- Sleep feeds creative thinking
(5 reasons that sleep exists)
Dreams can inspire noteworthy artistic & scientific achievements, such as dreams that clued a chemist to make the periodic table of elements.
- Sleep promotes growth
(5 reasons that sleep exists)
During sleep the pituitary gland releases a growth hormone that is necessary for muscle development. As we age, we release less of this hormone & spend less time in deep sleep (N3).
Hypnosis
A state or alternative state of consciousness with a openness to suggestion.
Hypnotic susceptibility
A persons ability to respond to suggestions that alter their perception, thoughts, emotions, behavior, or sensations.
