1) The document discusses Fitts's law, which states that there is a tradeoff between speed and accuracy in tasks. Faster movements compromise accuracy, and more accurate movements sacrifice speed. 2) An experiment was conducted with students focusing on either maximum speed or accuracy when tracing a star on a mirror tracer. Results showed those emphasizing speed had more errors, while those focusing on accuracy took longer. 3) The experiment provided evidence for Fitts's law - a tradeoff between speed and accuracy. When trying for both speed and accuracy, students were fastest but least accurate. Balance is needed between the two for optimal performance.
