Kinematic strategies underlying improvement in the acquisition of a sequential finger task with self-generated vs. Cued repetition training.

Many motor skills, such as typing, consist of articulating simple movements into novel sequences that are executed faster and smoother with practice. Dynamics of re-organization of these movement sequences with multi-session training and its dependence on the amount of self-regulation of pace during...
