Krashen's theory describes a mental device that edits output to improve accuracy. What is this device called?

• A. Monitoring
• B. Feedback
• C. Interference
• D. Scaffold

Answer: (A)

In Krashen's Monitor Model, the mental editor that checks and fixes language after you produce it is called the Monitor. It works like a self-correction mechanism: you use consciously learned rules to edit your output for accuracy, but it only kicks in when you have enough time and focus on form. Because it relies on explicit knowledge of rules, the Monitor helps with correctness more than with spontaneous fluency, and overreliance on it can slow you down. External feedback and the natural, automatic use of language come from different parts of the theory, while the Monitor is that internal, post-production check.
