📖 Reading Passage

The concept of 'cognitive load' refers to the total amount of mental effort being used in the working memory. In educational psychology, cognitive load theory suggests that learning is most effective when instructional materials are designed to minimize extraneous cognitive load, allowing learners to focus on essential information. Extraneous load is often caused by poor presentation or unnecessary complexity, while intrinsic load is inherent to the difficulty of the subject matter itself. Researchers argue that multimedia learning can reduce extraneous load by integrating visual and auditory information, but only if the design avoids redundancy and aligns with human cognitive architecture. However, critics note that individual differences, such as prior knowledge and working memory capacity, significantly influence how learners process such materials, making universal design principles difficult to establish.
