Noise, Information Transmission, and Force Variability
This study was designed to test the hypothesis derived from information theory that increases in the variability of motor responses result from increases in perceptual-motor noise. Young adults maintained isometric force for extended periods at different levels of their maximum voluntary contraction...

| description | This study was designed to test the hypothesis derived from
information theory that increases in the variability of motor
responses result from increases in perceptual-motor noise. Young
adults maintained isometric force for extended periods at different
levels of their maximum voluntary contraction. Force variability
(
SD
) increased exponentially as a function of force
level. However, the signal-to-noise ratio (
M/SD
),
an index of information transmission, as well as measures of noise
in both the time (approximate entropy) and frequency (power
spectrum) domains, changed according to an inverted
U
-shaped
function over the range of force levels. These findings indicate
that force variability is not directly related to noise but that
force output noisiness is positively correlated with the amount of
information transmitted. |
