Interventions/Control_1
Participants will perform an isometric pinch task in which they control a cursor on a computer screen using pinch force generated by the thumb and index finger to follow a moving target. The target size will be adjusted according to performance on each trial so that the task success rate is approximately 10%. Training will consist of four blocks of 20 trials with a 30-second rest between blocks. Ten assessment trials will be performed before training, immediately after training, and approximately 24 hours after training.
Interventions/Control_2
Participants will perform an isometric pinch task in which they control a cursor on a computer screen using pinch force generated by the thumb and index finger to follow a moving target. The target size will be adjusted according to performance on each trial so that the task success rate is approximately 40%. Training will consist of four blocks of 20 trials with a 30-second rest between blocks. Ten assessment trials will be performed before training, immediately after training, and approximately 24 hours after training.
Interventions/Control_3
Participants will perform an isometric pinch task in which they control a cursor on a computer screen using pinch force generated by the thumb and index finger to follow a moving target. The target size will be adjusted according to performance on each trial so that the task success rate is approximately 70%. Training will consist of four blocks of 20 trials with a 30-second rest between blocks. Ten assessment trials will be performed before training, immediately after training, and approximately 24 hours after training.
Interventions/Control_4
Participants will perform an isometric pinch task in which they control a cursor on a computer screen using pinch force generated by the thumb and index finger to follow a moving target. The target size will be adjusted according to performance on each trial so that the task success rate is approximately 90%. Training will consist of four blocks of 20 trials with a 30-second rest between blocks.
