Editing Language Development (section)

Language development is understood through '''Nativism''' and '''Interactionism'''.

'''1. The Biological Instinct (Nativism - Chomsky)''':
Children don't just "Copy" their parents.
* They say things they've never heard before (e.g., "I goed to the store").
* This "Over-regularization" (applying rules like '-ed' to everything) proves the child's brain is "Searching" for universal rules.
* Chomsky argued that humans are born with a "Template" for language already in their DNA.

'''2. The Social Environment (Interactionism - Bruner)''':
Biology isn't enough.
* If a child just listens to the TV, they won't learn to talk.
* Language is learned through "Joint Attention"—looking at a toy together and naming it.
* Parents use "Motherese" (Parentese)—slow, high-pitched, exaggerated speech—to help babies find the "Edges" of words.

'''3. The Statistical Brain''':
Recent research shows that babies are "Data Scientists."
* They listen to the frequency of sounds.
* If they hear "Pre-tty-ba-by," they notice that "Pre" is followed by "tty" much more often than "tty" is followed by "ba."
* They use this "Probability" to find where one word ends and the next begins.

'''Genie the Feral Child''': A tragic case study of a girl who was isolated until age 13. While she learned many words, she never mastered syntax (grammar), proving that there is a "Critical Period" for the brain to learn the *rules* of language.
