Me cavewoman today. 🦴 Me explain brain thing:
Brain have shelf. Small shelf.
Shelf called WORKING MEMORY.
Shelf hold thing you use RIGHT NOW.
You sit in meeting, boss talk fast.
You need remember: task one, task two, name of person you supposed to email.
That all sit on small shelf. Shelf to hold maybe 5 or 7 thing if lucky caveperson.
Brain also have big shelf far back in brain.
That called LONG-TERM MEMORY.
Long-term shelf hold EVERYTHING.
Name. Face of mother. How to tie shoe. Back shelf stay big.
Back shelf stay full forever, mostly.
Small shelf = juggle thing NOW.
Big shelf = hold thing FOREVER.
Brain also have cup, that called, SHORT-TERM MEMORY.
Hold thing little bit.
You hear name or number. Cup hold name or number few second. Then cup dump.
Gone.
Working memory different.
Working memory not just HOLD water. Working memory also STIR water. Working memory DO thing with information while holding it.
You not just remember number…you remember number AND do math with number AND remember why you doing math in first place.
That much harder job.
That why shelf so small.
Now, who struggle with small shelf?
ADHD.
Autism.
People tired.
People stressed.
Shelf get knocked over easy by worry, hunger, loud room.
Shelf not broken. Shelf just... smaller than other caveperson shelf.
Why this matter?
Small shelf needed to:
▪️Following instruction with many step.
▪️Conversation. Hold what person say WHILE thinking what you say back. Hard job for small shelf.
▪️Reading. Hold beginning of sentence while eye reach end of sentence.
▪️Math in head.
When shelf overload, or neurodivergent, thing fall off.
Person look "lazy".
Person NOT lazy.
Shelf just small and busy.
This why many people write list. Set timer. Say thing out loud twice. Use sticky note.
Smart caveperson use tool 😜
