1. Motor Control & Learning Level of control in all learning Learning produces changes in control

2. Learner Environment Task

3. Motor Skill Defined Requires body &/or limb movement Voluntary Goal directed Learned

4. Characteristics of Human Action Flexibility –Ability to recruit different muscles and joints to achieve same action Uniqueness –No two movements are ever performed in exactly the same way

5. Characteristics of Human Action Consistency of Action –Temporal and spatial aspects of a movement remain relatively stable from one performance to the next Modifiability of Action –Ability to alter a movement pattern, even as it is being executed

6. Classification of Motor Skills

7. One-Dimensional Classifications SIZE OF MUSCULATURE INVOLVED Gross motor Fine motor

8. One-Dimensional Classifications DISTINCTIVENESS OF MOVEMENT Discrete Continuous

9. One-Dimensional Classifications STABILITY OF ENVIRONMENT ClosedOpen

10. Environmental Dimension Demands placed on performer by the environment (Performance Space) Move Where?Spatial Move When?Temporal Move Where & When?Spatial & Temporal Constraints

11. Closed Skill Characteristics Self-paced Fixed Environment Spatial Control Highly Predictable

12. Open Skill Characteristics Externally-paced Changing Environment Spatial & Temporal control Skill Level of Performer
