This image illustrates the dominate mental state of participants walking through downtown Chattanooga (Meditative= blue, Anxious= red). Areas with low traffic, better views, and more green space induce a meditative state. Construction, traffic, and distraction induce anxiety. Implications for urban planning and mental health are evident. Of particular interest is the central bridge going over the river. This pedestrian-only bridge has the same view as the other bridges, but induces more meditation and less anxiety.
The two images above illustrate the differences between a first time marathon runner (left) and a much more experienced distance runner (right). The colors indicate hot (red) and cold (blue) spots for inward-attention. This mental state often arises when the participant is coping with fatigue, dissociating with pain, or striving to push through a wall. The variance of color in the left image demonstrates the wide range of mental changes encountered by a newer runner. The lack of color in the right image is likely due to better preparation, expectations, and energy usage during the race.
