Excerpt — Motor Learning and Performance 6th Edition With Web Study Guide-Loose-Leaf Edition

Applying the Principles: Baseball Batting

This is an excerpt from Motor Learning and Performance 6th Edition With Web Study Guide-Loose-Leaf Edition by Tim Lee & Richard Schmidt.It may seem from the previous section that sometimes contradictory princi­ples are involved in ­these rapid actions. To help in understanding, it ­will be useful to apply ­these princi­ples to a familiar task like batting in baseball. This task requires several of the pro­cesses discussed so far, such as anticipation and timing, prediction of the ball's spatial trajectory and its arrival time at the coincidence point, and rapid movements that must be both forceful and accurate, so the princi­ples...

Try the γ-V experiment

This is an excerpt from Motor Learning and Performance 6th Edition With Web Study Guide-Loose-Leaf Edition by Tim Lee & Richard Schmidt.The γ-­V Experiment Try this ­simple experiment for yourself. Draw small figures that represent the Greek letter gamma (γ) on a tablet, whiteboard, or sheet of paper taped to your desk. Draw the γ relatively quickly, without modification during its production. The figure must cross over near the center and have a rounded bottom. When you can do this effectively, use the other hand to draw regular Vs. The procedure is the same as before except that now the...

Understanding Fitts' Law

This is an excerpt from Motor Learning and Performance 6th Edition With Web Study Guide-Loose-Leaf Edition by Tim Lee & Richard Schmidt.Fitts' Law Fitts used a paradigm in which the participant tapped alternately between two target plates as quickly as pos­si­ble. The separation between the targets (termed A, for movement amplitude) and the width of the targets (termed W, for target width) could be varied in dif­fer­ent combinations (see figure 6.1). The movement time (MT) taken to complete ­these rapid taps increased systematically with ­either increases in the movement amplitude (due to a larger distance between the targets) or decreases...
