The document discusses several studies that examined factors influencing second language learning strategy use. It found that motivation is a key factor in language learning success. Female learners tended to use cognitive, metacognitive, and social strategies more than males. Younger learners relied heavily on cognitive and social strategies, while primary school children used metacognitive and social strategies most. An individual's background and learning style also impact the strategies they employ. Emotional states and personality traits can further influence classroom behavior and performance in language learning.
