Interference was the first experiment that I helped with in the motion capture lab.  When I began my mentorship, the experiment was already underway.  However I was able to pick up the procedure quickly and it actually helped my learning of how to run experiments in the mocap lab.  The basic hypothesis of the experiment is that depending on different conditions presented to a person, they are more or less distracted and able to perform a simple task that is given to them.  In order to test this theory, a series of movies were created using various methods.  These included a movie of a man, a human model, an ellipsoidal figure and a yellow ball.  In each of the movies, the figures would be either moving their arm horizontally or vertically.  A marker was placed on the right hand of the participant and they were asked to follow along with a series of movies that they saw.  The twist in the experiment was that a set of directions was shown to the participant prior to see each movie and they were required to follow the directions that they read.  As a result, the directions would either direct the participant to move similarly to the figure they saw, such as horizontal with horizontal, or move oppositely to the figure, such as horizontal with vertical.  We ran 64 separate trials of the experiment which we afterwards had to clean and process.  The data was then sent to the University of Virginia, for whom we were running the experiments, where they were analyzed.  Through the analysis of the data by calculating the differences in time of movement between the participant and the created movies, it was seen whether or not the different instances distracted the participants more or less in their ability to complete the task given to them.
