I'm always very happy to see different ways that people lay out and color mental models. This morning at UX Week, Adaptive Path unveiled an idea for a better insulin pump. As a part of their initial research, they created an alignment diagram (mental model) that separates behavior from emotion with color and location of the boxes. Behavior is shown in blue, emotion in pink. In addition frequency of behavior (or emotion?) also appears as a separate element. I applaud the tweaks they made to the model that went on to serve an important role in the design of their product.
