you can have an individual who is sexually developed, but still a child.
If you mean in mental respect then that's 90+% of post-teen foids anywhere, so what distinction are you making?
The distinction between child/non-child is a combination of biological maturation and cognitive development.
Will you call it misogyny if I question the cognition of women being so beyond?
I'm not referring to Piaget's model. Any similarity or overlap is a coincidental, not referential.
Which model then?
There is some point at which these cognitive processes that you listed occur,
but they are, by and large, happening only after pubescence.
The brain starts progressing its development after the body's development reaches the late stages.
You sound like you're approaching one of those "the age of consent should be 25 because that's when the prefrontal cortex stops growing and it's used for impulse control" bullshit post-wall feminist angles.
You don't need 100% growth in all brain parts. That certainly correlates with mental potential, but full size doesn't guarantee impressiveness any more than partial size guarantees incompetence. Plasticity and connections from experience seem more important than size.
the brain lets the body grow properly first in order to optimize its own development.
Pretty sure you're smarter and shit when you're newborn (ie how you learn languages and stuff) though this might be in respect to one type of intelligence and not other types.
Maturity/informedness just seems more like accrued learning than actual enhanced capacity. IE if you spend your first 20 years locked in a sensory isolation chamber, you're still a mental baby when you come out, not a mature woman.
Only extremely rarely does it happen prior.
It can happen with gifted children, for example, who truly do develop a complex understanding of things, despite their limited data (knowledge) and life experiences.
These are anomalous cases.
Foids developing a 'complex understanding of things' is limited even among adults, so why fixate on it?
A cognitively developed person who is not biologically mature would still be considered a child, by most conventional definitons of "child."
What's "biologically mature" though?
carta.anthropogeny.org
"growth in the pelvis of males may continue until 21 of age, and females may complete pelvic growth even later"
AOC 22 because pelvis has to be at max size before sex is okay?
That's what this leads to unless you want to explain why to draw the line X degrees earlier but not Y degrees earlier.
