Abstract

This research focuses on the fundamental role of the Mental Lexicon in Second Language (L2) processing, specifically within the framework of Psycholinguistics and Cognitive Science. The Mental Lexicon is defined as an organized repository of linguistic information (phonological, semantic, grammatical) that the mind relies on for comprehension and production. The study analyzes the cognitive differences between First Language (L1) and L2 processing in comprehension and production stages (such as phonological processing, lexical access, syntactic, and semantic processing), emphasizing the influence of L1 and the challenges in L2. The findings highlight the development of automaticity in phonological and semantic processing, where direct connections between L2 forms and concepts strengthen, and L1 mediation diminishes. This is explained within the framework of the Revised Hierarchical Model (RHM). This deep understanding provides a foundation for developing effective strategies in second language acquisition and learning.
