303 KD Building
The only way so many different people can agree about so much they experience in the world is if the fundamental substrate for those experiences is identical. This is clearly true at the level of gross physiology, but cognitive scientists believe that this is also true of more abstract categories of phenomena that underpin experience.
By abstract categories, I mean things like attention, memory, values, emotion, and motivation. These aren't physically observable phenomena, but seem to play important organizing roles in any meaningful analysis that tries to understand the lived experience. The hope of cognitive science is to clarify how and why these phenomena arise, interact, and dissipate.
I share this hope, and am trying to do my bit to help this project along, and to see how insights from this research can be used to improve the ways in which computing systems interact with humans.
