Motor Control Of Skills

Question 1

Hierarchical

Answer 1

An order of importance, e.g. The EMP are more important than sub-routines.

Question 2

Sequential

Answer 2

Sub-routines that are performed in a set order.

Question 3

Grooved and over learned

Answer 3

When the motor programme has been well learned and is stored in the LTM. A response. An now be made automatically in the autonomous stage

Question 4

Motor programme

Answer 4

A set of movement skills that have been stored in the LTM.

Question 5

Open loop control level 1

Answer 5

A system of subconscious control that does not use or reference feedback. ( the plan or EMP stored in the LTM——-> the action of the working muscles) Only effective when the environment is predictable.

Question 6

Memory trace

Answer 6

The executive motor programme (EMP)

Question 7

Memory items

Answer 7

• Knowledge of initial conditions
• Knowledge of response specifications
• knowledge of sensory consequences
• knowledge of movement outcome j

Question 8

Closed loop control level 2

Answer 8

Involves feedback and this is termed the perceptual trace. ( the EMP in the LTM—-(memory trace)——>the action of working muscles, then feedback via muscles back to the emp through kinaesthesis and proprioception during the skill.

Question 9

Closed loop control level 3

Answer 9

Feedback loop is longer because info of performance is relayed to the brain. (the emp in the LTM——-(memory trace)——-> the action of the working muscles—–(perceptual trace)—->back to the EMP.
