Research on the Generation Mechanism of Children's Language Acquisition and Its Subsequent Impacts in Multilingual Environments

In an era of increasing globalization and cross-cultural exchange, an increasing number of children are growing up in multilingual environments. This shift not only alters their language exposure patterns but also presents new challenges for research on language development. The mechanisms of language acquisition in multilingual settings have become a focal point in educational and psycholinguistic studies, prompting questions such as: How do children integrate input from different languages? Does multilingual experience promote cognitive and socio-emotional development? These inquiries hold significant implications for developing scientifically grounded educational strategies. Against this backdrop, this paper explores the mechanisms of language acquisition in multilingual children and the long-term effects of multilingual experience on their cognitive and social development. Based on generative grammar and a social interaction view, the research looks into children's mechanisms in language input, the processes of internalizing grammatical rules and constructing flexible language control systems. The results suggest that multilingual experiences not just improve development of executive function and attention, but also have beneficial effects on emotional aspects and cultural preference. But with obstacles such as lopsided language.
