Intrinsic Complexity

In Cognitive Load Theory, intrinsic complexity refers to the inherent difficulty of understanding and processing the content or material itself, as opposed to extraneous complexity which arises from how the material is presented or accessed. In accessibility contexts, distinguishing between intrinsic and extraneous complexities helps designers target appropriate interventions: intrinsic challenges (such as understanding complex musical rhythms from Braille notation) may require pedagogical support, while extraneous challenges (such as needing to remove hands from an instrument to read Braille) can be addressed through better interaction design. Reducing extraneous complexity through multimodal technologies frees cognitive resources for processing intrinsic content.
