Behavior of the 3 subsystems of voice production is a non-linear and emergent process
What is it about?
People produce voice differently, but the differences may not be completely idiosyncratic. Chaos theory describes stable and context dependent patterns of performance that appear under certain internal conditions called “attractors.” This paper describes the importance of both individual differences and commonalities of the relationships of the 3 vocalization subsystems, and why Dynamic Systems Theory (Chaos Theory) may be a useful guide to our thinking about how the nonlinear patterns of the 3 subsystems emerge during voicing.
Why is it important?
Understanding both individual differences and the determinants of how the 3 subsystems collect themselves under certain conditions helps make sense of the many possible degrees of freedom in which an individual may produce voice. Dynamic Systems Theory takes into account individual differences, but also helps catagorize individuals into smaller subgroups with some common behaviors. This may help better target therapy to individuals and is translational.
