Study Notes

Attractors and Phase Shifts in Human Movement Systems

Sudden phase shifts, or tipping points, are common in nature and occur when a system self-organizes into a new stable phase in response to external perturbations.
Systems prefer states of stability and self-organize into new stable phases, known as attractors, when the existing phase becomes unstable due to external constraints.
Attractors are organizational arrangements that keep a system's component parts working in harmony to fulfill the system's mission.
Human movement systems have attractors that maintain stable movement patterns with the greatest efficiency in specific situations.
An experiment by Kelso and Schoner demonstrated the role of attractors and phase shifts in human movement coordination.
In the experiment, subjects shifted from an antiphase pattern to an in-phase pattern when the speed of the metronome reached a critical point.
Two attractors were observed in the experiment, one organizing finger movements in an antiphase manner and the other in an in-phase manner.
Attractor basins collect and maintain patterns of behavior used in controlling a system, with some basins being shallow and easily susceptible to change, while others are deep and stable.
The depth of a basin, a preferred state of muscular-skeletal organization, is a function of genetics and learning, with well-learned skill patterns being deep and difficult to overcome.
The state space for a particular motor skill is made up of many attractors, with well-learned behaviors pooling into deeper and deeper basins.
In the early stages of learning a skill, most attractors available for controlling action are represented by shallow basins, making the associated behavioral patterns relatively unstable and easily disturbed by perturbations in the environment.
As individuals continue to learn, well-learned behaviors pool into deeper and deeper basins, resulting in more stable movement patterns.
