Perspectives and problems in motor learning

Movement provides the only means we have to interact with both the world an d other people. Such interactions can be hard-wired or learned through expe rience with the environment. Learning allows us to adapt to a changing phys ical environment as well as to novel conventions developed by society. Here we review motor learning from a computational perspective, exploring the n eed for motor learning,what is learned and how it is represented, and the m echanisms of learning. We relate these computational issues to empirical st udies on motor learning in humans.
