The concept of 'cognitive load' refers to the amount of mental effort required to process information. In educational psychology, researchers distinguish between intrinsic load, which is inherent to the complexity of the material, and extraneous load, which is generated by the way information is presented. Studies show that when extraneous load is high, learners struggle to allocate working memory to essential tasks, thereby reducing comprehension. Effective instructional design aims to minimize extraneous load through clear structure, visual aids, and the removal of irrelevant details. However, some scholars argue that a moderate level of challenge, known as germane load, is beneficial as it encourages deeper processing and schema construction. Thus, balancing these types of load is critical for optimizing learning outcomes.
