The previously untrained motor task: The investigators have chosen to use a functional upper extremity motor task that simulates feeding. This task requires participants to spoon beans (kidney, raw) from a central, proximal "start" cup to 3 distal "target" cups as fast as possible. The cups (9.5 centimeters in diameter) will be secured to a board with 3 cups secured radially at 45 degrees, 90 degrees, and 135 degrees around the start cup at a distance of 16 centimeters. The start cup will be oriented along the participant's midline and 15 centimeters in front of the seated participant. One repetition of the motor task will consist of spooning 2 beans at once from the start cup to a target cup with the non-dominant hand, with one trial equaling 15 repetitions. During each trial, participants will move first to the ipsilateral target cup, next to the center target cup, and then to the contralateral cup, relative to the hand used (right vs. left). This sequence will be repeated five times to complete the trial. The participant will begin each trial with their non-dominant hand to the side of the spoon. Each trial will begin as the administrator gives a verbal cue "go" and will end when the spoon is returned to the starting position (5 centimeters lateral to the start cup). The time it takes to complete the 15 repetitions ("trial time") will be the measure of performance, with faster times indicating better performance. All trials will be timed to the nearest 100th of a second via stopwatch. Participants will be given no explicit feedback (i.e. knowledge of performance or results) after each trial. They will also not be encouraged or coached to use a specific pattern of upper extremity kinematics during training.
