Abstract

Fitts' law and the ΔΛ model are “weak” theories of motor control because they are limited to the kinematic aspects of movement and do not capture its essential dynamic nature. The internal source of “noise” that determines the speed/ accuracy trade-off can be associated with the partial compensation of movement-generated “parasitic” forces.
