States of Consciousness Flashcards
(39 cards)
dualism
believe humans consist of two materials: thought and matter. Thought gives human free will, and also continues to exist even when we die
monism
disagree with dualism and believe that everything is the same substance, even thought and matter. Thought stops existing once we die.
priming
participants respond more quickly/accurately to questions they have seen before, even if they do not remember seeing them
blind sight
some people who report being blind can nonetheless accurately describe the path of a moving object or accurately grasp objects
conscious level
information you and your environment are currently aware of.
nonconscious level
body processes controlled by your mind that we are not usually aware of
preconscious level
information about yourself or environment that you are not currently thinking about but you could be.
subconscious level
information that we are not consciously aware of but we know must exist due to behavior.
unconscious level
some feelings and events are unacceptable to our conscious mind and they are repressed to the unconscious
circadian rhythm
in a 24-hour day, our metabolic and thought processes follow a certain pattern
sleep onset
period when we are falling asleep
What happens in sleep stages 1 and 2?
our brains produce theta waves, which are relatively high-frequency but get progressively slower. We also start to produce sleep spindles, where then we move onto the next stages.
sleep spindles
short bursts of rapid brain waves
What happens in sleep stages 3 and 4?
also known as delta sleep, this is where deep sleep occurs. If we are awakened from this, we may feel very groggy and disoriented as this is where our bodily processes replenish itself.
REM
this is also called paradoxical stage as our brain waves appear as active and intense as they do when we are awake. This is where dreams occur. Interference with this causes memory loss.
How long do these cycles take/repeat themselves?
they run approximately 90 minutes each, going about 4-7 times per night
insomnia
persistent problems getting to sleep at night
narcolepsy
suffer from periods of intense sleepiness and may fall asleep at unpredictable and inappropriate times.
sleep apnea
causes a person to stop breathing for short periods of time, making us wake up and slightly gasp for air before sleep continues. This robs our deep sleep and interferes with attention and memories.
night terrors
usually affect children; where they wake up in the middle of the night and scream but do not remember this episode.
somnambulism
sleep walking; usually affect children
manifest content
literal content of your dreams
latent content
unconscious meaning of manifest content
activation-synthesis theory of dreams
looks at dreams as biological phenomena as our brain is very active during REM sleep. It simply proposes that dreams are nothing more than brain’s interpretations of what is happening physiologically.
