States of Consciousness Flashcards
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.
information-processing theory of dreams
points out that stress during the day will increase number and intensity of dreams during night. Dreams relate to daily concerns and processing events into memories
posthypnotic amnesia
when people report forgetting events that occurred while being hypnotized
posthypnotic suggestion
suggestion that a hypnotized person behave in a certain way after brought out of hypnosis
role theory of hypnosis
states that hypnosis is not an altered state of consciousness at all, and enforces hypnotic suggestibility
hypnotic suggestibility
some people are more easily hypnotized than others
state theory of hypnosis
point out that hypnosis meets some parts of the definition for an altered state of consciousness; and there are many health benefits for hypnosis.
dissociation theory of hypnosis
hypnosis causes us to divide our consciousness voluntarily; so that one part of our consciousness responds to hypnotist and the other retains awareness of reality
blood-brain barrier
brain is protected from harmful chemicals in the bloodstream; but some molecules can pass through it
agonists
drugs that mimic neurotransmitters
antagonists
drugs that block neurotransmitters
What are stimulants and what are some examples?
speed up body processes, including heart and respiration rate and the sense of euphoria. This includes caffeine, cocaine, amphetamines and nicotine
What are depressants and what are some examples?
slow down body processes. This includes alcohol, barbiturates, and antianxiety drugs (such as Valium)
What are hallucinogens and what are some examples?
change perceptions in reality. Includes LSD, mushrooms, marijuana.
reverse tolerance
second dose may be less than the first but cause greater effects
opiates
powerful painkillers and mood elevators. Include morphine, heroin, methadone, and codeine.
