Does Overpractice Improve Motor Learning?

Subjects will perform a standing serial reaction time task on a step reaction mat. Subjects will step to a series of targets, based on a series of stimuli that are presented. One trial is composed of two 12-step sequences. One of the 12-step sequences is random, while the other is a repeated sequence; sequences are presented in random order. After each trial, the subject rests for 25 seconds. Six trials equal 1 block of practice, which is followed by a 4 minute rest break. After each block, feedback is provided about average response time (RT) on all steps included in the block. One complete day of practice consists of 6 blocks of practice in which each block consists of 6 trials.
