This document discusses several factors that affect language learning strategies: language proficiency level, motivation, learning style, gender, and age. Regarding proficiency level, studies found that more proficient learners use more cognitive and metacognitive strategies, while beginners rely more on translation. Motivation also influences strategy use, with more motivated learners adopting strategies more frequently. Learning style impacts strategy selection, such as introverts preferring metacognitive strategies. Gender differences show females using compensation and affective strategies more, while males favor metacognitive and compensation strategies. Younger learners progress from receptive to communicative strategies, and some advanced secondary students favor metacognitive strategies.
