Intrinsic and Required Dynamics of a Simple Bat-Ball Skill
Three experiments investigated the coordination dynamics of a simple bat-and-ball skill: cyclically striking a ball suspended by a string with a pendular bat. The relative phase φ between the bat and ball is dictated by the potential function V (φ) = k sin φ and the difference Δω in their uncoupled...

Zusammenfassung: | Three experiments investigated the coordination dynamics of a
simple bat-and-ball skill: cyclically striking a ball suspended by a
string with a pendular bat. The relative phase φ between the bat and
ball is dictated by the potential function
V
(φ) =
k
sin φ and the difference Δω in their uncoupled
frequencies. For various Δω, φ and its standard deviation were
measured in the absence of any environmental restraints (intrinsic
dynamics) and when the ball had to reach resistive or nonresistive
targets at set distances (required dynamics). Results support the
dynamical theory of coordination patterns (

1988c
), particularly the hypothesis that
required dynamics are understandable as the addition of terms to the
potential governing the intrinsic dynamics. |
