Noam Chomsky argued that children are not born with enough exposure to their native languages to explain phoneme understanding; this concept is known as

• A. Poverty of the stimulus
• B. Universal grammar
• C. Nativist critique
• D. Empiricism

Answer: (A)

The idea being tested is that there isn’t enough linguistic input in a child’s environment to fully explain how they come to understand phonemes, suggesting there is some innate knowledge guiding language learning. This specific claim is captured by the term poverty of the stimulus. It highlights that the data children hear is often incomplete or ambiguous, yet they still infer the correct phoneme categories and develop robust pronunciation systems. That gap between input and knowledge points to an innate aspect of language ability, a core point Chomsky emphasized.

Universal grammar is related but broader, referring to a set of deep, universal principles that underlie all languages. The situation described—the insufficiency of input to explain phoneme learning—points to poverty of the stimulus as the precise label. Empiricism would argue all knowledge comes from experience, which runs counter to this idea. A nativist critique isn’t the standard term used for this specific phenomenon.
