HCI Project Analysis and Cognitive Psychology

A while back we had an intro human computer interaction course where we learned affinity diagrams. As an assignment we had to create one ourselves. Essentially it is a way to logically group and organize the steps out something. In particularly we had to make one for our project. Below is a diagram which shows that.


We had a speaker today. Her name was Dr.Dark and she was a cognitive psychologist. It was an interesting talk on different types reasoning that we go through in order to process the information that we receive. In particular she talked about distal and proximal stimulus. Basically, distal stimulus comes from the world around us where as proximal comes from ourselves. This relates to the idea of bottom up and top down reasoning. In top down reasoning we are more likely to interpret information in the world based on our own perception as opposed to bottom up reasoning which is based on whats actually in the world. To me this posed the question of, “Is there a way to determine if someone is more likely to use top down or bottom up reasoning?” If so, is there a difference in how fast they come to their perceived conclusion and is there a difference in how accurate that conclusion really is. This could then be applied to stressful situations and how someone may respond to said situation. Will they use top down or bottom up reasoning and then depending on which one was used, how will that effect the outcome of the situation that they are in? All in all this would be an interesting study to conduct that could potentially be applied to enforcement training and their hiring process along with other highly stressful careers.
