This document discusses 5 factors that affect language learning strategy use: motivation, gender, learning styles, language proficiency, and beliefs. For each factor, several studies are cited that examine the relationship between that factor and strategy use. The studies generally find that more motivated, female, and proficient learners tend to use strategies more frequently and in different ways than less motivated, male, and proficient learners. Learning style and beliefs about language learning are also found to influence an individual's strategy use.
