Limited transfer of learning between unimanual and bimanual skills within the same limb

Nat Neurosci. 2006 Nov;9(11):1364-6. doi: 10.1038/nn1785. Epub 2006 Oct 8.


Although a limb's motion appears to be similar across unimanual and bimanual movements, here we demonstrate partial, but not complete, transfer of learning across these behavioral contexts, hidden learning that remains intact (but invisible) until the original context is again encountered, and the ability to associate two conflicting force fields simultaneously, one with each context. These results suggest partial, but not complete, overlap in the learning processes involved in the acquisition of unimanual and bimanual skills.
