Editing Capacity Limitations Principle (section)

=== Challenges ===

1. Determining the limits of cognitive processing: 
Although the maximum capacity of short-term memory is around 4 items of information at a time,  the specific cognitive limit for each individual is difficult to determine. The specific limit of each individual learner's cognitive processing can vary based on factors including age, experience, prior knowledge, and task demands. It can be difficult to accurately predict the limits of cognitive processing in a given context, and this can make it challenging to apply the principle effectively.

2. Balancing simplicity and completeness: 
Another challenge is balancing the need for simplicity with the need for completeness. On one hand, it is important to limit the amount of information displayed in a display to a level that the viewer can process and remember effectively. On the other hand, it is also important to ensure that the display includes all of the necessary and relevant information needed to convey the intended message or achieve the desired outcome. It can be challenging to follow The Principle of Capacity Limitations when the amount of information required to successfully convey the intended message is beyond the anticipated capacity of the working memory. 

3. Dealing with complex or unfamiliar information: 
A third challenge is dealing with complex or unfamiliar information, as it can be difficult for the viewer to accurately perceive and understand this type of information. In these cases, it may be necessary to use additional design strategies, such as providing context or background information, or breaking the information down into smaller, more manageable chunks.
