This document discusses interactionist and developmental perspectives on language acquisition. It argues that innatist theories focus too much on the end state of language and not enough on its developmental process. Interactionism holds that language acquisition stems from children's innate ability to learn from social experience and exposure to language from caretakers. Caretaker talk, which includes modifications like slower speech, helps make language comprehensible to children. Children learn language through enjoying repetitive events, focusing on what they understand, and using their primary interests to communicate and build confidence.
