What does the Monitor Hypothesis suggest about language learning?

The Monitor Hypothesis, proposed by Stephen Krashen, emphasizes the role of conscious learning in language use. The correct choice highlights that grammar rules play a crucial role in language monitoring. According to this hypothesis, language learners use learned grammatical rules to "monitor" their spontaneous speech or writing. This means that while individuals may rely primarily on their natural ability to communicate, they can also refer to formal grammar rules to ensure correctness in their output. When learners have sufficient time and cognitive resources, they can apply these rules to adjust their language use, promoting greater accuracy and fluency over time. This understanding reinforces the importance of grammar in the learning process, as it provides a framework for self-correction and reflection, thereby enhancing overall language competence.

The other options do not align with the key tenets of the Monitor Hypothesis. For example, while it's true that self-correction is part of the learning process, the hypothesis suggests that grammar rules are essential for this monitoring. Furthermore, feedback is actually considered significant in language acquisition, assisting learners in refining their understanding of language structures and usage.
