LESSON 1.5 - Dynamical Pattern/Systems Theory Flashcards
1
Q
Dynamical Systems/Pattern Theory
A
- a transdisciplinary theory
- emphasizes the need to understand natural phenomena as a complex system with many interacting component parts, each of which is capable of affecting other parts
2
Q
How biological systems behave
A
- natural tendency to want to achieve order or stabilize (self-organize)
- stability is demonstrated through a propensity for pattern formation
- capacity to use environmental energy to sustain functional periods of stability that benefit the whole system (energy efficient)
- e.g., fish swim together in a particular pattern to be in a complex system. if one fish is gone, there will be a change in pattern and they will coordinate themselves again
3
Q
Complex Systems
A
- dynamic
- nonlinear (unpredictable)
- spontaneously adjusts or self-organizes (change occurs within the system)
4
Q
in-phase and anti-phase relative phase pattern of human bimanual coordination
A
in-phase: coordination pattern in which two movement components oscillate in 0-degree relative phase
- one limb in a phase is relative to your other limb (in together, out together)
anti-phase: coordination pattern in which two movements oscillate in 180-degree relative phase
- (one limb is up, one limb is down)
- walking is not anti-phase, but your limbs are in an anti-phase cycle
5
Q
attractor state
A
Attractor state: refers to the preferred patterns of movement (or sates of stability) in which a system spontaneously shifts towards on your dynamical landscape
6
Q
Haken-Kelso Bunz (HKB) Model in relation to control parameter, phase transition, perturbation, variability, and destabilization
A
quantitative model
- control parameter: cycling frequency which causes phase transition into a more stable state
- perturbation: deviation of a system moving the object
- variability: when variability increases, stability decreases
- destabilization: upsetting stability
