Name and describe the three levels of processing and how they matter in terms of design

Visceral - snap judgement processing based on fast cognition brain functions. Tied with perception in the form of our immediate senses (touch, taste, smell sight, hearing). Visceral processing influences us greater than we realize and happens in such a subtle way that it's very important for designers to pay attention to how their products draw the attention of visceral emotions.

Behavioral - Is the learned processing based off past experiences. This occurs instantaneously and without much thought. Trouble arrives in design when behavioral processing does not match with what actually happens. For instance clicking a pen to write but the pen doesn't come out.

Reflective - Reflective is the processing that is mainly conscious evaluations of what happen. This level of processing is slow and laborious. Too much reflective processing is stressful as humans are designed to maximize resources while minimizing their effort. This is what leads to satisficing (learning just enough to accomplish the goal, even if it means using a product wrong)
