Q

Introspection

A

Researchers analyze people’s retrospective thoughts on an experience (usually sense)
Subjective and not reliable for recording SIMILAR psychological process
* because we describe things differently, but maybe we all actually do think the same?
Instead- observable behavior _ supposedly more objective (which then becomes subjective when the researcher describes/ classifies it)
Brain imaging is truly objective but again that lil subjective kick

Q

Objective consciousness

A

Something that we will ALL similarly and INITIALLY (before analysis takes place) describe/ label

EX: knives are for cutting
* ofc not truly objective

Q

Exceptions to objectivity

A
  • Ofc never truly objective because organized and overarching societal rules are alr established and we abide by them
  • also mentally ill ppl might actually see something else (vision can be subjective too)

Q

Circadian rhythms

A

Circadian- about a day
In which brain activity, sleep/ wake cycles, Body temperature and hormone levels
Influenced by the perception of light and dark (not totally dependent)
Maintained by brain regions
EX: see hypothalamus card

Q

Hypothalamus on circadian rhythm

A

Info about light is sent to small region here called suprachiasmatic nucleus
Then pineal gland (endocrine)
Releases melatonin
bright light stops production of melatonin

Q

Sleep fact s

A

Sleep less as we age and still gain energy, BUT normally bad to function on so little sleep
MS:
- Adults- 9-10 to feel rest
- babies- much of day
- @@old ppl don’t go back to sleep easily and spend less time in stage N3@@

Q

Conscious and biological in sleep

A

Asleep= Different Conscious experiences and biological processes
Conscience exp- To some extent you remain aware of surroundings (tossing and turning- but not falling after infancy)
Biological - brain doesn’t sleep when you do
Really active

Q

Healthy sleep (4 stages)

A

Non-REM= NREM
1. Stage N1 sleep (first NREM)- slowly unaware of outer world AND thoughts- theta
2. Stage N2 sleep- all thoughts stop
3. Stage N3 sleep- deep sleep
4. REM sleep- dream- beta
Cycles 5 times

Q

Stage N1

A

THETA waves
Before actual sleep where you see crazy shit but still have inches of conscious thought (for me its a thinking train spiraling down)
Hypnic jerks
Geometric shapes (is this because when you boil down our consciousness its all the shapes we see in the world OR our thoughts are really shapes)

Q

Stage N2

A

Sensitive sleep
Sudden loud noises-> K-complexes (large waves) - signals from brain functions that keep you asleep by shutting out the outside world
Sleep spindles -> occasional bursts of energy

Q

REM (stage R/ paradoxical sleep)

A

After 90s minutes -> reverses ALL the way back to N1 sleep
Flurry of beta waves that usually are for awake state, BUT its only certain UNUSED parts of brain that are awake now
Rapid eye movements
Muscles are paralyzed expect for genital arousal
Dreams

Q

Sleep cycle

A

Go through stages 5 times
Nearing the morning, cycles shorten and N3 is little to none but MORE REM than anything

Q

Hypnosis

A

When responding to suggestions, a persons memory, perception and free will changes
“Suggestions” but really manifestation mantras

25
Hypnosis truth
Hypnotist cant just hypnotize anyone forcefully, the person must willingly follow suggestions (so are they truly unconscious or not) Works more for ppl that are highly gullible (perception and will is KEY) Not being dictated easily, having great imagination
26
Sociocognitive theory of hypnosis (1/2)
The person socially accepts the suggestions SO puts them into cognitive acceptance and ACTS them out willingly
27
Dissociation theory of hypnosis (2/2)
Social context is important but it LITERALLY changes state of consciousness Consciouss awareness (normal) is dissociated from other aspects of consciousness (trance) Brian activity Can’t totally change brain activity to simply please hypnotists, let alone psychological researchers EX:literally change the duties of a brain region (visual cortex that perceives color) to instead reverse the function which it normally doesn’t do !! Activating that region in general is proof enough @@@ Functions change-> consciousness does too@@@
28
Hypnotic analgesia (pain)
Detach from sensations of pain (less activity in regions that process pain) Basically strengthening our will power, bypassing our weak boundary of not being able to really get to that point of stoicism/ immunity The doubters wont have access to this superpower (Supports dissociation theory)
29
Anxiety and hypnosis
Typically, around four to six sessions can help you to learn new methods of coping, to replace unhelpful or harmful thought patterns or past negative associations with new, more positive ones.
30
What makes a Psychoactive drug
Any mind/ brain neurochemistry-altering substance that activate neurotransmitter systems (caffeine)
31
4 main classes of drugs
1. Stimulants (coffee/ increase behavior and mental activity- gives anxiety) 2. Depressants (decrease behavior and mental activity- stops overthinking) 3. Opioids (reduce pain and give pleasure/ heroin) 4. Hallucinogens (crazy town anything and everything goes)
32
Thing about drugs
Effects of drugs depend on which neurotransmitter systems it activates
33
Restorative theory/ Benefits of sleep
Brain needs to rest and repair GH repairs damaged tissue Strengthen immune system Let’s brain replenish energy stores Support neural connections (card) Prepares brain for its memory needs for next day
34
Circadian rhythm theory
Sleep is a biologically (evolved) survival system We sleep at night because we cant see in the dark (more in danger)
35
Consolidation theory/ Sleep spindles benefits
ALOT of sleep spindles strengthen LEARNING neural connections (n2 - non REM dreams- like i if i think about a fact i learned during NREM dream) Those made during waking state are strengthened even more Old ppl get less of these (sleep less)
36
Let’s tell this to Val
Sleep deprivation for even ONE night leads to memory loss, reduced brain activity the next day (brain arras essential for memory)
37
Transcendental meditation (TM)
Popular in WEST Hyper focus 20 minutes twice a day
38
Benefits of meditation
Long term- structural changes that help maintain brain function over life span EX: brain volume usually diminishes with age, but not here Preserves cognitive functioning (correlational) Improves attention Reduces stress (less vivid emotional experiences) Lowers blood pressure Levels of fatty acid and cholesterol Signs of diabetes
39
Zaza
No nausea in chemotherapy patients Heightened sense of taste Perceptual and cognitive distortions (no anxiety) APPARENTLY newbies dont get the high that stoners get Psychological disorders and violent behavior later in life
40
How to get substance abuse disorder?
Anything that enhances dopamine activity (drugs) is likely to be repeated (we chase pleasure) LOTS of Activated dopamine receptors in limbic system Inherit risk taking + impulsive genes Role models Parents are addicts Addicts eventually find drugs less pleasurable but still use to cope with THIS dilemma They desensitize themselves from pain unknowingly and so cycle BEGINS with this realization that they all of a sudden cant deal with pain (lost experience)
41
Automatic processing (consciousness)
The pros at something do it automatically
42
Neurons in consciousness
Established brain activity (neural) pattern that we associate every single experience (baby neurons card) Brain activity = neural patterns (and we know what brian activities mean for our consciousness ) More generally and more specialized-> when CERTAIN neuron groups are activated, in turn, a CERTAINNN conscious experience (i think I just reworded the above thing, but I like to think that we switch consciousness in the slightest ((like I suddenly change mindsets)
43
Global workspace model (1/2)
The key to all our “subjective” thought questions - we all commonly activate specific areas of our brain when analyzing something (neurons in consciousness card) But since our brains are so complex, @@other areas HAVE to turn on too, when there are emotions AND memories attached to mere association (fusiform face area)@@ SPECIIFC Brain region activity= conscious awareness of SPECIIFC info Yes we all have the same brain activity, because of similar cultural and social norms that have fundamentally constructed our neural connections It would not be the case if we were all isolated, unless to the smallest degree it does (brain areas) and thats all that matters The regions are the key here
44
Concussions
Not just a mild TBI (traumatic brain injury) Increase in multiple sclerosis later in life
45
Concussion facts
Females are more vulnerable and have worse outcomes
46
Global workspace model (2/2)
General Psychological processes are supported by simultaneous activity of all the diff brain regions Frontal lobe isn’t EXCLUSIVE to our deeper meaning of life awareness shit Maybe all of the things each region bring in do center around a singular consciousness and contribute, and consciousness is not so separate? This is why TBIs negatively affect consciousness
47
MDMA
Less dopamine acitivty More serotonin and norepinephrine activity Hallucinations and sweaty fats heart rate respectively Damage to prefrontal cortex (cant do hard tasks), hippocampus (memory problems) Benefits- treats PTSD (in low doses so it doesn’t hurt cognition)
48
Insomnia
Inability to sleep-> lowers mental health and ability to function Older adults, women Sleeping pills don’t work in long run -> instead do CBT cognitive behavioral therapy
49
Sleep apnea
Throat closes in sleep, so they can’t breathe and WAKE UP Men and obesity , cardiovascular disease/ stroke Can’t concentrate when driving, tired in daytime Loud snoring- otherwise they don’t know they have it in the morning
50
Narcolepsy
Sleeepy bye while teaching one million people how to say yes Rare Muscle paralysis (REM behavior) Sleep attacks Genetic that affects transmission of a neurotransmitter in hypothalamus Cure- stimulants
51
REM behavior disorder/ NOT sleepwalking
No muscle paralysis (normal REM tings) I dance in my dream, I dance in my bed Older males, Neurological deficit
52
Somnambulism (sleepwalking)
Young children Slow-wave sleep (N3) NOT a person acting unit dream Glassy-eyed, unaware of surroundings
53
Alcohol and sleep
Helps you sleep, but will mess up your sleep cycle
54
Sleep tips
Sleeping late in the morning , napping, or both will make the next nights sleep more difficult
55
Effects of sleep deprivation
Catch more diseases Can still perform complex tasks Irritable mood Memory loss
56
REM dreams
Come from the activation of brain structures associated with motivation, reward, and emotion (for example, the amygdala). The visual association areas, motor cortex, and brain stem are also activated. At the same time, the prefrontal cortex becomes less activated
57
Non rem dreams
Everyday situations
58
REM dream vs NR dream
Activity of diff brain regions during rem and NR create diff types of dreams and your perception of them NR- generally less active regions R- SOME increased acitivty, SOME don’t
59
Manifest content / latent content
Visual info manifested in dream and hwo it’s remembered by dreamer latent- message behind visual info which is then “disguised” by manifest content, BUT it could very well be a result of how fucking vivid our unconscious mind is and how our complex souls and mind and spirit express itself (we are all capable of magic)
60
Activation synthesis theory (dreams)
Neurons for sensory input randomly fire, but there is no LITERAL sensory input happening Brain regions that process the input in waking state do so but brain is confused by it Our sleeping brain Makes sense of it by combining the sensory activity with memories and emotions its all whacked out and out of order (like daydreaming or just Viking with your neurons during the day)
61
Waves
Small and short at normal and REM (beta) N2- sleep spindles and k-complex spikes N3- huge steady waves (delta) Can we recall how long we were asleep (how long it FELT)
62
Types of meditation
