What level of consciousness the process of awareness indicates?



States of Consciousness (Part 1) 

Some basic definitions:

∙ Consciousness

o Awareness of external events and internal sensations while under a  condition of arousal

∙ Awareness vs. arousal

∙ Awareness is more of a subjective state

∙ The subjective state of reflecting about yourself,  

your thoughts, and your experiences. A form of  

metacognition

∙ Metacognition is thinking about thinking

∙ Thinking about the fact that you saw  

something

∙ Arousal is more about being awake


What controls sleep wakefulness and consciousness?



∙ Physiological state of being engaged with the  

environment

∙ Physiological state of being awake

∙ Example: Zombies are aroused but not

awake

∙ Levels of Awareness

o Higher-level consciousness

∙ This is the controlled processing, in which individuals are  actively thinking and alerts

∙ Focused on their tasks and goals

∙ You have to think about what you are doing in order

to do it well

∙ Examples: Studying or learning a new skill  

like driving a car or playing an instrument

o Lower-level consciousness


What drugs cause sleep deprivation?



∙ This is the automatic processing and daydreaming, which  requires little attention and focus

∙ Activities that require very little attention

∙ For example, anything you’ve done a bunch of  Don't forget about the age old question of What is decision-making like in international relations?

times your cerebellum takes control and makes it a type of  

"muscle memory"

∙ Driving a car is second nature now because  

we've been doing it for awhile

o Altered states of consciousness

∙ Produced by drugs, trauma and fatigue

∙ Your brain no longer is working in the way that it should  be

∙ Psychoactive drugs can cause this or just simply  

sleep deprivation

∙ Examples: being under the influence of  

alcohol

o Subconscious awareness

February 18th 2016

∙ Usually occurs when people are asleep and dreaming, but also  occurs when we are awake Don't forget about the age old question of What desired effects does acetaminophen have?

∙ You are not completely unconscious in this state

∙ If this happens when you are awake it is normally in

a person with a traumatic brain injury

∙ Examples:

∙ Blind sight

∙ These people cannot see but  We also discuss several other topics like Who is the amesbury archer?

can still respond to stimuli

∙ If someone holds up a  

ball they cant see it, but if a ball is  

thrown at them they can catch it

∙ Split-brain patients

∙ Are shown something on their  

left side but the right hemisphere doesn’t  

process it so they "never" saw it

o No awareness

∙ Usually happens when we are knocked out or anesthetized, but  can also occur when we are awake

∙ Cannot be woken up

∙ This is someone that is completely unaware of anything  going on around them

∙ Sigmund Freud believed that there are parts of us  

that we never use because they have no awareness

∙ Circadian Rhythms

o Behaviors that synchronize with the 24 hour cycle of the day ∙ Our biological clocks

∙ We are pretty good at telling how much times has passed to a  certain point

∙ Examples:

∙ Sleep/wake cycle

∙ Body temperature

∙ Lowest in the morning and peaks in the early

evening

∙ Blood pressure If you want to learn more check out Can a proposition be true or false?

∙ Cycles throughout the day, fluctuates

∙ Blood sugar level

∙ These are down at night and rise in the  

morning

o How do our bodies know what time is it?

∙ Because of our biological clocks

∙ The biological clock is a brain system that detects the  passage of time , using internal and external cues

∙ It uses this to regulate our body systems  

∙ You have several different types of cues that the brain  uses to regulate the clock

o Where is our biological clock?

∙ Located in the hypothalamus (which controls body regulation)

February 18th 2016

∙ To be more specific it is in the suprachiasmatic nucleus  (SCN)

∙ The SCN is a part of the hypothalamus that uses  

input from the eyes to synchronize its rhythm with the daily

cycle of light and dark

∙ There is a connection from your eyes to your  

hypothalamus so you can tell what time of day it is  

and regulate your biological clocks

o Zeitgerber Don't forget about the age old question of What are the three steps taken to create a karyotype?

∙ This is your "time giver"

∙ This is what we refer to light as, it helps us regulate our  clocks

∙ For example we actually run on a 25 hour cycle if  

we were to be locked in a room with no light, but light and  

dark cues make our clocks run on a 24 hour cycle

o What happens If you remove the SCN?

∙ This would screw up your entire sleep rhythm, you would no  longer have control over your wake/sleep cycle

∙ Instead of sleeping when its dark for example, you would  do it in a random pattern We also discuss several other topics like What ship did the union navy used to try to defeat the confederate ironclad?

o What is a normal sleeping pattern?

∙ The average person needs about 8 hours of sleep

∙ The average young adult needs anywhere from 9 to 10  hours

∙ Some people need less, some people need more

o Morning and Night people:

∙ Morning people are okay with changing states of consciousness  and that is why they seem to have a better time waking up

∙ Night owls tend to be people who dislike changing states of  consciousness

∙ They "fight" sleep or have a hard time going to bed early  because when they are awake they want to stay awake and  

have a hard time getting up in the morning because when they  are asleep they want to stay asleep

o What are the effects of sleep deprivation?

∙ You get cranky or irritable

∙ You have poor memory

∙ Make bad moral judgements

∙ And it actually can make you unhealthy so, more health costs ∙ It also messes with serotonin levels

∙ Serotonin deals with eating, sleeping and mood; if you  deprive yourself of one you mess up the other two

o What happens to your clock when you disrupt your sleep/wake cycle ∙ There are several examples:

∙ Jet lag

∙ Time changes make your clocks set up to match  

the time zone you are in, if you change time zones your  

clocks have to "reset" to be on time with the current time

∙ Its easier to go west then it is to go east

February 18th 2016

∙ Night shift work

∙ You are going against what the body naturally  

wants to do

∙ So, you're making yourself stay awake late at

night and sleep during that day and that is hard to  

adjust to

∙ All nighters

∙ Pulling one of these makes you want to sleep  

during the day because you are tired but if you do that you  

wont sleep the following night so it messes up the whole  

entire schedule

∙ Its better to just be sleep deprived for one  

day  

∙ Insomnia

∙ In this case anything that makes you more aroused  

can keep you awake and mess up your sleep/wake cycles

o What can we do to reset our clocks?

∙ Try sleeping and waking up at appropriate times

∙ Exposing yourself to light and dark cues

∙ Melatonin

∙ This is a drug that is naturally released before you go to  sleep

∙ Higher at night than in the morning

∙ You can take supplements to help you sleep
