Motor Control - Theories Of Motor Control

Question 1

What is the top-down model?

Answer 1

-mind instructs the muscle

Feedback enables movement to be controlled and adjusted

Question 2

What is information?

Answer 2

The content of a message that serves to reduce uncertainty.

Question 3

Where does information come from?

Answer 3

• Environment via the senses

- Memory

Question 4

Define motor programmes.

Answer 4

A motor programme is an abstract code or structure that, when executed, results in a movement.
(Human action controlled by stored commands)

Question 5

List the stages of IP in order of how they happen.

Answer 5

• Stimulus
• Stimulus identification
• Response selection
• Response programming
• Response
• Output

Question 6

Define Open loop control.

Answer 6

-A control system with pre-programmed instructions to an effector that does not use feedback information and error detection processes.

Question 7

Define Closed loop control.

Answer 7

A control system that involves the use of feedback and the activity of error detection and correction processes to maintain the desired goal.

Question 8

What does the executive do?

Answer 8

• Generates movement

- Issues commands

Question 9

What does the effector do?

Answer 9

-Carries out movements (muscles/joints)

Question 10

Which system does not use feedback during the movement?

Answer 10

Open loop system

Question 11

What are the two major perspectives of motor control?

Answer 11

1.The cognitive/Traditional view
•Open/closed loop control
•Schema theory
2.The dynamic systems/ecological approach
