The Bottom Up and Top Down of Cognitive Science

In cognitive science, it's called the bottom up and top down. Bottom up means that you're creating a simulation that mimics the way in our case the way the eyes and the brain are working. Top down is for example, changes in the vertical space. When we see something pops in front of us, then maybe it means Jane danger or something to be aware of. All of them together are combined into those road data that we produce as reports such as heat map, gaze, prediction and other variation which are just different interpretation of the same data.
