Age Differences in Noise and Variability of Isometric Force Production.
Deutsch, Katherine M.; Newell, Karl M.
Journal of Experimental Child Psychology, v80 n4 p392-408 Dec 2001
Examined whether age-related improvements in children's motor performance result from reduced noise in the output of the sensorimotor system. Found that performance improved with age. The force output signal exhibited increased irregularity and a more broadband frequency profile with increasing age under feedback. There were no age differences in irregularity of the force signal.
