As the trials went on the participant's dominant hand showed significant improvement in not only the tracing but also with time. In the beginning, she started tracing by going clockwise and that stayed consistent throughout the experiment. She frequently changed the position of her nondominant hand when using it to hold the paper in place. The time of her first trial was 9.2 seconds, the 12th trial was significantly faster than the first with a time of 4.83 seconds.
Shut circle control utilizes criticism alongside mistake location and revision to keep up the ideal state. During the task of tracing the participant had to pay attention to the line and make sure they didn’t move out of the desired area. If they moved out of this area they would detect that an error occurred which would require them to correct it to get back to the desired area.

An aspect of the task that might not have been controlled in a closed-loop mode is when the participant was asked to use their non-dominant hand. An open loop system has no knowledge of the output condition so it's hard for it to self-correct any errors that were made. This is similar to many people who try using their non-dominant hand.
The factor that might have influenced my results is that my participant typically wears glasses and she did not have them during the time of the study. When asked to participate in the study she agreed and we sat down so I could explain it to her. In the middle of the study, she made a comment about not having her glasses on which made it her have to focus more to be able to see better. While getting her glasses would have been desired, I instructed her to just continue without them as it would have altered the rest of the task.
