Factors that affect language learning strategy (LLS) usage include proficiency level, learning style, the language being learned, beliefs, degree of awareness, and motivation. Studies have found high proficiency is associated with increased use of both direct and indirect LLS. Learning style refers to how a learner processes information. The language being learned influences the strategies used based on the learner's goals. Learner beliefs also influence strategy use. Degree of awareness refers to a learner's understanding of themselves and their learning process. Strong motivation is closely correlated with greater LLS use and is a key factor in language learning success.
