Stroop Test - Gait Lab

The Stroop Test is a way to measure selective concentration as well as reaction time. It requires finding a baseline reading of how quickly you can do a simple task, and then requires you to do a similar task but while ignoring certain stimuli. Exercise improved reaction time in both cases. I believe this is because an elevated heart rate leads to a higher level of alertness, which leads to an improved reaction time. Biologically this makes sense as an elevated heart rate would often coincide with important, possibly dangerous situations where higher alertness would be beneficial.
