Flashcards in Week 5 - Dynamical Systems Deck (13):
1

What is the collective variable in the kelso experiment?

Relative phase

2

What is the control parameter in the kelso experiment?

Movement frequency

3

Switch from anti to in phase in kelso experiment is what feature of the self-organization system?

Bifurication

4

What is the dynamical systems approach to skilled movements called?

Unconstrained manifold

5

Which of the four fundamental problems of motor behaviour is the dynamical systems approach PRIMARILY trying to solve?

Degrees of freedom

6

What are the 6 features of the self-organization system?

Pattern formation, Bifurications (transitions), Multistability, Hysteresis, Critical Slowing down and Critical fluctuations

7

What are discrete movements?

Movements with a clear beginning and end

8

What are continuous (rhythmic) movements?

Movements that repeat

9

Why is most dynamical research based on rhythmic movements?

important biologically and easy to study

10

What did Kelso think about discrete and rhythmic movements?

Believed that discrete movements are overdamped rhythmic movements

11

What did Sternad think about discrete and rhythmic movements?

Believed that they are two seperate movements

12

What did Jirsa think about discrete and rhythmic movements?

Used the excitator model, which is motivated by models of a neuron.

13

What is the dynamical systems approach to skilled movements called?

Unconstrained manifold
