Motor Control & Learning Level of control in all learning

Motor Control & Learning

• Level of control in all learning

• Learning produces changes in control

Motor Skill Defined

• Requires body &/or limb movement

• Voluntary

• Goal directed

• Learned

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

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

Classification of Motor Skills

One-Dimensional Classifications

• SIZE OF MUSCULATURE INVOLVED

• Gross motor Fine motor

One-Dimensional Classifications

• DISTINCTIVENESS OF MOVEMENT

• Discrete Continuous

One-Dimensional Classifications

• STABILITY OF ENVIRONMENT

• Closed Open

Environmental Dimension

• Demands placed on performer by the environment (Performance Space)

• Move Where? Spatial

• Move When? Temporal

• Move Where & When? Spatial & Temporal

Closed Skill

• Characteristics

• Self-paced
• Fixed Environment
• Spatial Control
• Highly Predictable

Open Skill

• Characteristics

• Externally-paced
• Changing Environment
• Spatial & Temporal control
• Skill Level of Performer

Two-Dimensional Classification

• Stationary Motion

• No variability Variability

Two-Dimensional Classification

• Body Stability Object

• Body Transport No Object

Why is two-dimensional classification system useful?
