Which hypothesis distinguishes unconscious language acquisition from conscious language learning?

• A. Acquisition-learning hypothesis
• B. Input hypothesis
• C. Monitor Hypothesis
• D. Affective-filter Hypothesis

Answer: (A)

Two separate routes to language development are proposed: unconscious acquisition and conscious learning. The Acquisition-Learning Hypothesis argues these are distinct systems in the mind, with acquisition arising from natural, meaningful communication and operating unconsciously, while learning is the conscious knowledge of language rules that can be verbalized and applied deliberately. This is exactly the distinction the question is asking about—one path is unconscious and intuitive, the other is conscious and rule-based. The other theories don’t set up this explicit split: the Input Hypothesis focuses on understanding language through exposure to comprehensible input; the Monitor Hypothesis describes how conscious knowledge can serve as a monitor to edit speech but doesn’t define acquisition versus learning as separate systems; the Affective-filter Hypothesis explains how emotions affect language processing rather than the separation of unconscious and conscious knowledge.
