A Comprehensive Investigation of Psycholinguistic Mechanisms Contributing to Reading Fluency in Second Language Learners

Abstract

Reading fluency is a fundamental component of second language (L2) literacy, yet many learners experience persistent difficulties in achieving automatic, accurate, and expressive reading despite receiving formal language instruction. These challenges often stem from complex psycholinguistic processes, including lexical access, phonological processing, working memory, syntactic parsing, and semantic integration, which collectively influence reading performance. This study aims to comprehensively investigate the psycholinguistic mechanisms contributing to reading fluency in second language learners and to identify the cognitive and linguistic factors that most strongly predict fluent reading. A quantitative research design was employed using standardized reading fluency assessments and psycholinguistic measures administered to second language learners from diverse educational settings. The collected data were analyzed through descriptive statistics, correlation analysis, and multiple regression techniques to examine the relationships among psycholinguistic variables and reading fluency outcomes. The findings indicate that phonological awareness, rapid automatized naming, vocabulary knowledge, working memory capacity, and lexical retrieval speed are significant predictors of reading fluency, while syntactic processing and semantic integration further enhance reading comprehension and overall performance. The study demonstrates that reading fluency develops through the interaction of multiple cognitive and linguistic mechanisms rather than a single isolated process. These findings have important implications for language educators, curriculum developers, and policymakers by emphasizing the need for evidence-based instructional strategies that strengthen psycholinguistic skills alongside traditional reading instruction. Integrating cognitive and linguistic interventions into second language education can substantially improve learners' reading fluency, comprehension, and overall academic achievement.
