The Effects of Task Complexity on Second Language Learners’ Pragmatic Knowledge Development: A Review of Literature

This study examines the impact of task complexity on the development of pragmatic knowledge in second language (L2) learners. Utilizing Robinson’s Triadic Componential Framework, the research focuses on the variable of [+/- no reasoning demands] and its influence on the production of various pragmatic forms such as requests, refusals, suggestions, and persuasions. The study reviews five empirical investigations that manipulate task complexity and analyze its effects on L2 learners’ pragmatic performances. Results indicate that complex tasks elicit a higher quantity of pragmatic-related episodes (PREs), fostering deeper engagement with sociopragmatic factors. However, the variety of pragmatic forms produced did not significantly increase with task complexity, suggesting a need for additional strategies to encourage linguistic diversity. The findings support the application of task-based language teaching (TBLT) in enhancing pragmatic competence and provide insights into optimizing task design for effective language instruction. Implications for future research and pedagogical practices are discussed, emphasizing the importance of diverse task modalities and comprehensive evaluations of pragmatic development.
