Can watching others move improve your own performance?

This study looked at whether watching someone else perform reaching movements can improve your own ability to do the same task. 60 healthy adults were split into three groups: one watched arm movements, one watched light sequences, and one watched nature videos. Their own reaching speed and accuracy were tested before, right after, and 24 hours later. The goal was to understand if the benefit comes from seeing the movement itself or just learning the sequence.
