PML 5 Dynamical systems approach Flashcards
What is the degree of freedom problem (Bernstein)?
There are too many independent variables that need to be controlled
What are the 3 stages of learning (Bernstein)
- initial stage
- second stage
- third stage
coordinative structure
temporary task-specific organization of the movement system that emerges out of interaction of constraints
Dynamic systems approach
aims to understand stability and change of (behavioral) systems.
behavior is not prescribes but emerges from interaction of component system and environment
order parameter
low-dimensional description of the behavioral states of a system with many components
control parameter
aspecific variable that guides the system through its different stages
attractor landscape
preferred behavioral states of system modelled as a landscape with valleys
What affects the layout of the landscape?
The control parameter
Phase transition
range of control parameter induces a change in order parameter
Attractors emerge and dissapear
intrinsic dynamics
behavioral patterns at the start of learning
what means learning in the dynamical systems approach?
it implies changing or modifying the intrinsic dynamics
scanning procedure; seagull effect
rate the intrinsic dynamics before, during and after learning
Behavioral information
specifies what pattern needs to be learned
cooperative
to be learned pattern is identical to the intrinsic dynamics
competitive
to be learned pattern is not part of the intrinsic dynamics
