our brain making extreme rationalization when confronted with something it can’t make sense of

torf none of us are immune to confabulation

information, discounting

torf your brain is constantly engaged in a complicated sorting process and your often unaware

t

torf we’re often unaware of our attention unless smth goes wrong or we need to be constantly focused

maintains a low level of awareness of the other conversations, incase it hears something relevent

your _____ is a relevant thing your brain may listen for

name

endogenous attention

involves focusing your attention on something because the desire to do so comes from within you (bc you want to)

endogenous attention is sometimes called

top down attention

top down attention is a name used for endogenous attention bc

the inclination to focus attention is coming from the upper level of the brain’s desires

exogenous attention

t

ex of visual attention

reading, movie, scrolling on phone

torf when ur attending to something that is more visual (or a specific sense) than the visual cortex (or that senses area) activity increases

t

when testing a visual endogenous attention task the _________________ and _____________ are highly active

frontal eye fields, intaparietal sulcus

frrontal eye fields

frontal lobes, important role in focusing your visual gaze based on endogenous attention

intraparietal sulcus

in parietal lobe, highly active when we focus attention on something we deem important

sulcus

one of the deep groves covering the surface of the brain

torf FEF and IS seem to lead the way in directiing visual attention but also recruit many other brain regions to ensrue smooth operation

t

blue

frontal eye fields

intraparietal sulcus

torf there is a separate attention network for exogenous attention which is main focused on the right side of the brain

t

primary players of exogenous attention network

temporoparietal junction and the ventral frontal cortex

temporoparietal junction

temporal and parietal lobes meet, active when attention is shifted, is suppressed when focusing on endogenous attention

ventral frontal cortex

active during shifts of exogenous attention, important to the function of memory/maintaining memory

torf if activity in one network decreases the other increases, showing they work together

t

a limit of attention is that while we can change what we focus on it has a ________________

limited capacity

to test the limits of your attention doctors used headphones where each ear is saying different things which led them to find out

F

supertaskers

people immune to the negative effects of multitasking

supertaskers took a test that involves hearing a task followed by a math problem example:

“Cat” followed by “is three divided by one minus one equal to two?” followed by “box”

torf over 97% of participants of the supertaskers test displayed severely impaired performance

t

torf 2.5% of participants of the supertaskers test displayed no impact to performance or improvements

t

about __ in every 100 [ep[;e are supertaskers

2

Attention-Deficit/Hyperactivity disorder (ADHD)

studies show that mindfulness/meditation as well as excercise for __ weeks can help improve cognitive control and attention

in us about 1 in every ___ children is taking adhd meds

20

it is thought adhd happening is related to the neurotransmitters:

dopamine and norepinephrine

old name for adhd

minimal brain dysfunction

minimal brain dysfunction

originally thought the condition was caused by a small degree of brain damage

amphetamine causes levels of _______________ to increase in synapse

dopamine and norepinephrine

torf its likely that adhd is caused by low levels of dopamine and norepinephrine

t

torf low levels of dopamine can cause the brain to have a difficult time devoting the right amount of attention to something
