Which concept argues that the input children receive is insufficient to account for their phoneme knowledge?

Which concept argues that the input children receive is insufficient to account for their phoneme knowledge?

• A. Poverty of Stimulus
• B. Comprehensible Input
• C. Affective-filter Hypothesis
• D. Input Hypothesis

Answer: (A)

Poverty of Stimulus argues that the input children hear is not enough by itself to fully determine their knowledge of phonemes. Even though adults speak around them, the data is noisy, limited, and sometimes ambiguous, yet children still acquire clear phoneme categories and pronunciation patterns. This gap between what is heard and what is known suggests there must be innate tendencies or mental representations guiding learning, beyond the evidence in the speech input. The other ideas focus on input being enough or on factors like emotion that affect learning, so they don’t address why the linguistic data available to children is insufficient to explain phoneme knowledge.
