Sample 1
Which statement best describes the role of the affective filter in language learning, according to Krashen's theory?
Why the answer fits: The affective filter is a psychological BARRIER — when stress, anxiety, or boredom are high, the filter goes UP and blocks acquisition. When the learner is relaxed and motivated, the filter goes down. Options A, B, D describe other Krashen ideas (mental representation, LAD, conscious learning).
Tip: For Krashen 'best describes' questions, match each option to the right concept: LAD (innate ability), affective filter (emotional barrier), monitor (conscious editing), input hypothesis (i+1).
Why the other choices are wrong
- A. That describes Universal Grammar / mental representation, not the affective filter.
- B. That's the Language Acquisition Device (LAD), not the affective filter.
- D. That's conscious 'learning' (Krashen's other concept), not the affective filter, which is about emotion-based blocking.
