The Impact of Age on Second Language Acquisition

Abstract

Age is a critical factor in second language acquisition (SLA), influencing not only the level of proficiency of learners but also the strategies they employ during the learning process. This paper examines how age affects different components of language learning such as pronunciation, grammar, vocabulary, and motivation drawing on the Critical Period Hypothesis (CPH) and contemporary research findings. Evidence suggested that younger learners are more likely to develop their pronunciations and grammatical structures like native speakers, whereas older learners typically rely on explicit learning strategies supported by advanced cognitive skills. This study also emphasized the significant role of social context and motivation, showing that age interacts with individual characteristics and environmental factors. Age may confer certain advantages to younger learners, while older learners bring different benefits to the learning process.
