The study conducted was to test how well we could remember certain patterns over time.  We were asked to determine whether a picture we saw was taken inside or outside, and remember which of four quadrants on the screen it appeared in.  After the initial stage of seeing all the pictures, we did a math page for five minutes, when were shown all pictures again in a different order.  When a picture appeared we had to remember which quadrant it appeared in.  We also had our heart rate and blood pressure taken incrementally throughout the testing.  We did not experience any stressors, as we were simply the control group, but from what I understand future groups will be exposed to some form of a stressor to measure the affects.
