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, thereby freeing resources for the intrinsic load necessary to understand complex material. Research has shown that presenting information through multiple modalities, such as combining visual diagrams with spoken explanations, can reduce extraneous load by preventing the split-attention effect, where learners must mentally integrate disparate sources of information. However, this benefit is contingent on the learner's prior knowledge; novices may benefit from integrated formats, while experts might experience redundancy, as they can process information more efficiently without redundant cues. Thus, effective instructional design must consider the learner's level of expertise to optimize cognitive processing and enhance learning outcomes.
