Identify potential experimental design flaws.

          Prior to engaging in our peripheral vision experiment we had to run practice sessions on ourselves to ensure that the task did not impose any foreseeable difficulties on the participants. Upon my first attempt at the exercise I found that the tracking task could easily be completed while turning my head toward the peripherally projected image thereby looking at both the foveal and peripheral tasks with the same amount of visual attention. We then reasoned that because peripheral vision is more devoted to change detection and foveal vision is devoted more to detail orientation both tasks (tracking and change notification) could be monitored via peripheral vision when not on the extreme edge of the visual periphery. Turning the head to a position that allowed both tasks to be well inside the extreme made it simpler to "cheat" the experiment. This is the first design flaw I identified.
