This document discusses 5 factors that affect language learning strategies: language proficiency, motivation, learning style, gender, and experience. Language proficiency determines whether learners employ more cognitive or metacognitive strategies. Motivation consists of goals, effort, wants and attitudes that can be instrumental or integrative. Learning style influences how learners understand information, with extroverts preferring social strategies and introverts using metacognitive strategies more. Studies show females use language learning strategies more frequently than males. Experience studying a language can impact the strategies learners choose to use.
