Five factors affect language learning strategies: intelligence, aptitude, personality, motivation/attitude, and learning styles. Intelligence, as measured by IQ scores, predicts success with analytic learning but may be less important for communicative focus. Aptitude includes abilities in sound identification, word functions/meanings, and grammar rules. Personality traits like anxiety, extroversion, and inhibition impact language learning. Motivation depends on communicative needs and language attitude. Learning styles are visual, auditory, or kinesthetic preferences for acquiring information. Teachers can motivate students and vary activities to engage different learning styles.
