COGNITIVE FATIGUE DYNAMICS IN SECOND LANGUAGE ACQUISITION: A NEUROCOGNITIVE AND DEVELOPMENTAL PERSPECTIVE
Keywords:
cognitive fatigue, second language acquisition, executive function, working memory, neurolinguistics, sustainable learningAbstract
This article examines cognitive fatigue as a dynamic neuropsychological factor influencing second language acquisition (SLA). While SLA research has traditionally emphasized grammatical competence and lexical development, the fluctuating depletion of executive cognitive resources during sustained language processing remains underexplored. Drawing upon executive function theory, cognitive load theory, and neurolinguistic processing models, the study proposes the Cognitive Fatigue Regulation Model (CFRM), which conceptualizes how prolonged linguistic effort affects fluency, comprehension, and learner motivation. Developmental differences in fatigue manifestation across children, adolescents, adults, and elderly learners are analyzed. The article argues that sustainable language education requires fatigue-aware instructional design and adaptive pacing strategies.
