Abstract:
This comprehensive review examines the empirical evidence and theoretical frameworks surrounding age-related differences in second language acquisition, addressing the fundamental question of why children demonstrate superior language learning abilities compared to adults. Through systematic analysis of research spanning neuroscience, cognitive psychology, and sociolinguistics, this article synthesizes findings from cross-sectional, longitudinal, and experimental studies to provide a nuanced understanding of age effects in language learning. The evidence reveals domain-specific patterns of age advantages, with the most robust and consistent findings occurring in phonological acquisition. Children beginning second language learning before age 6-7 consistently achieve more native-like pronunciation than later learners, supported by neurophysiological evidence showing more efficient neural processing in early bilinguals. Morphosyntactic development presents a more complex picture, with apparent age advantages often mediated by cognitive factors such as working memory capacity and analytical abilities. The research challenges simple critical period explanations, revealing that age effects result from complex interactions between neurobiological factors (neural plasticity, brain lateralization), cognitive development (implicit versus explicit learning systems), and social-environmental variables (motivation, learning context, self-consciousness). While children benefit from greater neural plasticity and immersive social learning environments, substantial individual variation exists across all age groups, with exceptional adult learners achieving near-native competence in multiple linguistic domains. This review concludes that successful language acquisition remains possible throughout the lifespan, with individual differences in cognitive aptitude, motivation, and learning strategies potentially more predictive of ultimate attainment than age alone. Future research should focus on developing comprehensive theoretical models that integrate neurobiological, cognitive, and social factors while translating findings into practical applications for optimizing language learning across different age groups.
