Nature vs Nurture Debate: This debate centers around whether human behavior (including language acquisition) is primarily influenced by genetics (nature) or environmental factors (nurture).
Behaviorism: Behaviorism is a psychological approach that emphasizes the role of external stimuli in shaping behavior. It contrasts with Chomsky's theory by focusing on observable behaviors rather than innate abilities.
Critical Period Hypothesis: This hypothesis suggests that there is an optimal period in early childhood during which language acquisition must occur for it to develop normally. Beyond this critical period, language acquisition becomes more challenging.
