Transfer of learning is a process through which practicing
a motor task in one condition improves performance in
another condition. It has been shown that: (1) when one arm
has learned a novel motor task, the other nontrained arm may
demonstrate improved performance in the same task [1],[2],
(2) practicing a unimanual task may lead to improved
performance of a similar bimanual task [3] and (3) practicing
a bimanual motor task may lead to improved performance of
a similar unimanual task [4]-[5].
