Answer 1

Relative phase

Question 2

What is the control parameter in the kelso experiment?

Answer 2

Movement frequency

Question 3

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

Answer 3

Bifurication

Question 4

What is the dynamical systems approach to skilled movements called?

Answer 4

Unconstrained manifold

Question 5

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

Answer 5

Degrees of freedom

Question 6

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

Answer 6

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

Question 7

What are discrete movements?

Answer 7

Movements with a clear beginning and end

Question 8

What are continuous (rhythmic) movements?

Answer 8

Movements that repeat

Question 9

Why is most dynamical research based on rhythmic movements?

Answer 9

important biologically and easy to study

Question 10

What did Kelso think about discrete and rhythmic movements?

Answer 10

Believed that discrete movements are overdamped rhythmic movements

Question 11

What did Sternad think about discrete and rhythmic movements?

Answer 11

Believed that they are two seperate movements

Question 12

What did Jirsa think about discrete and rhythmic movements?

Answer 12

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

Question 13

What is the dynamical systems approach to skilled movements called?

Answer 13

Unconstrained manifold
