The Role of Age in Second Language Development

Abstract

This article delves into the ongoing debate surrounding the role of age in second language acquisition, examining developments over the past three decades and highlighting contentious issues. We argue that the commonly held belief in age’s pivotal role is frequently contradicted by empirical evidence. Additionally, we examine the age-related debate with respect to foreign language teaching. A brief review is provided on advances in neuroscientific techniques, which show that the adult brain retains substantial plasticity for language learning, followed by a discussion of these findings in relation to lifelong language learning. Finally, we turn to Complex Dynamic Systems Theory, which offers a dynamic perspective that emphasizes the evolving interplay of age, context, and individual factors, pointing to the need for more qualitative research.
