Background: This study investigates the effects of higher and lower-level text processing strategies on both higher and lower-level processing skills and cognitive load using the computer-assisted interactive reading model (CAIRM) as the educational intervention framework. Objectives: The objectives of this study are to examine the effects of the CAIRM model on reading performance and cognitive load, and to investigate the interactive use of higher-level and lower-level text processing skills on reading performance and cognitive load. Methods: A mixed methods research design was used with QUAN + QUAL data and one-way ANOVA to examine the effects of the CAIRM model on 120 randomly sampled BA students majoring in TEFL. Results: The study provides empirical evidence for the interactivity effect in digital text processing, revealing that the development of one skill can enhance the development of another skill interactively. The interactive use of higher-level and lower-level text processing skills was found to improve reading performance and reduce cognitive load during digital text processing. Interestingly, the results show that some participants preferred lower-level skills, while others preferred higher-level skills to manage cognitive load during reading activities, indicating mixed effects in strategy use. Conclusion: The findings of this study underscore the importance of interactive use of higher and lower-level text processing skills for enhancing reading performance and reducing cognitive load during digital text processing. These results have both theoretical and pedagogical implications for CALL researchers and practitioners, emphasising the need for personalised instruction tailored to individual learners' needs and preferences. Future studies can further explore the potential effects of text processing skills and develop instructional strategies to optimise learners' reading performance and cognitive load. Overall, the study contributes to the growing body of literature in CALL and highlights the significance of interactive learning models for improving learning outcomes.
