The Role of Cognitive Load in Foreign Language Learning: Psycholinguistic Challenges and Pedagogical Solutions

Cognitive load plays an important role in foreign language learning because learners must process unfamiliar vocabulary, grammatical structures, pronunciation patterns, and contextual information while working with limited working-memory resources. When the mental demands of a learning task exceed learners’ available cognitive resources, comprehension, information retention, and language production may be negatively affected. This article examines the role of cognitive load in foreign language learning from psycholinguistic and pedagogical perspectives. It aims to identify major sources of cognitive overload and explore instructional strategies that can facilitate language acquisition. A narrative literature review was conducted using foundational theoretical publications, research syntheses, and empirical studies on cognitive load theory, second language task complexity, vocabulary acquisition, and multimedia learning. The reviewed literature indicates that segmenting complex materials, integrating relevant visual and verbal information, adapting task difficulty to learners’ proficiency levels, and providing structured practice can support learning efficiency. However, the effectiveness of these strategies depends on prior knowledge, task characteristics, and individual learner differences. The article concludes that effective foreign language teaching should neither eliminate cognitive effort nor overload learners, but should manage mental demands to facilitate meaningful processing, retention, and the gradual development of communicative competence.
