Week 4 Motor Programmes

Question 1

What are deaffereniation studies?

Answer 1

When sensory feedback is removed and all movements must be preplanned

Question 2

What are selection errors?

Answer 2

Choosing the wrong motor programme

Question 3

What are execution errors?

Answer 3

correct motor programme chosen, but wrongly executed

Question 4

What are the two problems with motor programs that generalized motor programs were meant to solve?

Answer 4

Novelty and storage

Question 5

What is different from generalized motor programs and motor programs?

Answer 5

Far more flexible and ‘force impulses’ are stored instead of muscle activation patterns

Question 6

What is motor equivalence

Answer 6

Same task can be accomplished by a number of different effectors

Question 7

What are the invariant properties for a generalized motor program?

Answer 7

order of events, relative timing and relative force

Question 8

What properties can change in a generalized motor program?

Answer 8

Overall duration, overall force and muscle selection

Question 9

How does impulse timing explain motor equivalence?

Answer 9

Suggests that what a generalized motor program contains are force-time curves
