Which interaction design technique reduces cognitive workload by simplifying information presented to the user?

Progressive disclosure is a design technique aimed at minimizing cognitive overload by presenting information to users in a way that simplifies their experience. It achieves this by offering only the necessary information at each step or interaction, while more complex or additional details are provided progressively as needed. This method allows users to focus on their immediate task without being overwhelmed by all available information at once, leading to a more intuitive and user-friendly experience.

By limiting the information displayed initially, users can easily assimilate what is most relevant to them, thus reducing their cognitive workload. As users interact with the system and their needs evolve, additional layers of information can be revealed, ensuring that the user remains engaged without feeling inundated.

In contrast, other techniques like incremental reveal may not focus as effectively on reducing cognitive load through structured information layering, while contextual design and user-centered design encompass broader approaches to understanding and solving user needs but do not specifically highlight the concept of managing cognitive workload through information presentation.
