Cognitive Load

Cognitive load theory is a framework for understanding how the human brain processes information. It is based on the idea that the brain has a limited capacity for processing information, and that when this capacity is exceeded, learning and performance can suffer.

Why is cognitive load important?

Cognitive load is important because it can affect our ability to learn and perform tasks. When the cognitive load is too high, we can become overwhelmed and unable to process information effectively. This can lead to errors, frustration, and disengagement.

There are three types of cognitive load: intrinsic, extraneous, and germane.

• Intrinsic cognitive load is the amount of mental effort required to understand the material itself. This is determined by the complexity of the material and the learner's prior knowledge.
• Extraneous cognitive load is the amount of mental effort required to deal with the way the material is presented. This is determined by the clarity of the instructions, the organization of the material, and the use of visuals.
• Germane cognitive load is the amount of mental effort required to make connections between new and old knowledge. This is determined by the learner's ability to relate the new material to their existing knowledge and skills.
