The theories of language development—learning theory, social pragmatism, and nativism—each contain elements of truth. An integrated approach is more realistic, as it combines insights from all three. Learning theory explains how sounds, words, and meanings are acquired; social pragmatism emphasizes the role of social interaction; and nativism highlights the inherent creativity of language.
Modern psychologists agree that language acquisition cannot be fully understood by looking at environmental or genetic factors alone. Instead, they recognize that children are born with an innate ability to learn language, which is shaped and reinforced by learning experiences. Language development arises from a complex interaction of genetic predispositions, maturation, learning strategies, and social contexts, with no single factor being sufficient on its own. Future research should focus on exploring how these various factors interact to provide a more comprehensive understanding of language acquisition.
