It is important to know that while neuroscience has progressed dramatically over the last decades; there is no complete understanding of how human memory works. We know, for example, that data in the brain is stored in clusters of neurons but we don’t know how, precisely, it is stored or even how it is encoded. Thus when it comes to understanding memory from a design perspective we will examine certain properties of human memory that are commonly understood to be correct.
Human memory doesn’t exist in isolation; the brain isn’t just responsible for memorizing things but also for processing the data and acting on that data. Much of our memory and much of the information we receive is visual and it is with visual memories that the designer is mainly concerned.
