Abstract
Fitts' law and the Delta Lambda model are ''weak'' theories of motor c ontrol because they are limited to the kinematic aspects of movement a nd do not capture its essential dynamic nature. The internal source of ''noise'' that determines the speed/accuracy trade-off can be associa ted with the partial compensation of movement-generated ''parasitic'' forces.
