Psychology - Principles of Motor Control and Movement Accuracy

Question 1

What do performers adjust to produce variations of a class of movements?

Answer 1

Previously generalised motor programs and parameters.

Question 2

Examples of parameter values for when kicking/throwing a ball for example?

Answer 2

Movement time/speed.
Movement amplitude/size.
Overall force.
Trajectory.

Question 3

When the same movement or technique is performed at different speeds, how are all the parts of the movement changed? Ratio of the time of each part to the total time of the movement remain what?

Answer 3

Uniformly.

Ratio of the time of each part to the total time of the movement remain the same.

Question 4

What does the relative timing pattern provide?

Answer 4

The ‘rhythm’ of an action.

Question 5

What is relative timing referred to as?

Answer 5

The ‘deep structure’ of the movement.

Question 6

How is a relative timing sequence established?

Answer 6

Through repeated practice.
