KIN 315 Motor Learning Fall 2009 Name Lab 11 Variability of Practice Purpose: To investigate whether experiencing several variations of a skill during practice (i.e., practice variability) is more beneficial than one variation for increasing the likelihood of success when a novel variation of the skill must be performed. Task and Equipment Needed The task involves tossing beanbags at a target. The goal is to be as accurate as possible with each toss. The participant stands at designated locations from the target goal, facing away from the target. On command, he/she tosses a beanbag over the right or left shoulder (depending on whether the person is right or left handed) trying to get the beanbag to stop as close to the center of the target as possible. After the beanbag lands on the target, the scorer tells the participant the score of the toss (i.e., +2, -5, 0, etc.). The participant should not ever turn to look back at the target. The participant should be told that the goal of the task is to hit the target, which is indicated by a 0 score (meaning no error), and that the score for each trial indicates the direction (“-“ means short of the target; “+” means past the target) and the distance away from the target (1 is the closest; 10 is the farthest) for a toss. [Note that any toss that lands beyond the segments marked 10 should be scored as +/- 10.] Equipment:
