The process of acquiring a foreign language is a sophisticated neurobiological undertaking that extends far beyond simple vocabulary memorization. This article explores the Neural Mechanisms of Speech Processing and the Impact of Cognitive Constraints on Language Learning, examining how the structural and functional architecture of the human brain influences linguistic proficiency. By synthesizing contemporary research in neurolinguistics and cognitive psychology, the study investigates the critical roles played by the prefrontal cortex and the temporal lobes in decoding non-native phonological systems. A primary focus is placed on the declarative/procedural model, which explains the transition from conscious rule-following to automatic language production. The analysis reveals that the effectiveness of this transition is frequently hindered by specific cognitive constraints, most notably the limitations of working memory and the metabolic costs of inhibitory control. As learners navigate the competition between their native language (L1) and the target language (L2), the brain must exert significant neural effort to suppress L1 interference, a process managed by the anterior cingulate cortex.
