This work critically addresses the age debate in second language acquisition studies, presenting an in-depth study of factors that predict foreign accent. Quantitative and qualitative analyses confirm that cognitive, social, and psychological factors contribute to attainment, and that biological influences must therefore be considered alongside these essential aspects of learner experience.
