The term "cognitive load" refers to the cognitive load or mental stress that arises when processing information. This concept is crucial when it comes to how people absorb, understand and retain information. Cognitive load can be divided into different categories, namely intrinsic, extrinsic and germane load.

Intrinsic cognitive load refers to the difficulty of a task itself. The more complex the task, the higher the intrinsic load. For example, when reading a complicated scientific text, the intrinsic load is high.

Extrinsic cognitive load, on the other hand, is due to external factors that can make it difficult to process information. These include distractions, noise or inappropriate forms of presentation. If someone tries to study in a noisy environment, the extrinsic load is increased.

Germanic cognitive load, on the other hand, has a positive connotation. It refers to the cognitive load required for a deeper understanding and solution of a task. For example, when we learn a new concept and activate our thought processes to understand it, germane load is created.

Why is the concept of cognitive load important? Well, it has direct implications for learning, teaching and the design of information. If we want people to learn and retain information effectively, we need to ensure that the load is not too high. This can be achieved by presenting information clearly, reducing distractions and encouraging active cognitive processes.

In education, for example, it is important to design teaching materials in such a way that they minimise the intrinsic load and maximise the germane load. This enables learners to understand more deeply and retain what they have learnt better.

In the world of technology and user experience, reducing extrinsic stress is crucial. User-friendly interfaces and well-designed applications should minimise distractions and focus on the essentials.

Overall, understanding cognitive load is of great importance to enable effective learning, efficient information processing and better design of interfaces and materials. It is a concept that plays a central role in both psychology and practical application.
