A Transactional Model of Causality in
Motor Development and Movement
Skill Acquisition
Categories of Movement
• Stability
• Locomotion
• Manipulation
Motor Development
Theoretical Frameworks
• Dynamic systems theory
• Phases of motor development
Dynamic Systems Theory
• Affordances—enabling factors
• Rate limiters—inhibiting factors
Phases of Motor Development
•
•
•
•
Reflexive
Rudimentary
Fundamental
Specialized
Reflexive Movement Phase
• Information encoding stage
(in utero to 4 months)
• Information decoding stage
(4 months to 1 year)
Rudimentary Movement Phase
• Reflex inhibition stage
(birth to 1 year)
• Precontrol stage
(1 to 2 years)
Fundamental Movement Phase
• Initial stage
(2 to 3 years)
• Elementary stage
(4 to 5 years)
• Mature stage
(6 to 7 years)
Specialized Movement Phase
• Transition stage
(7 to 10 years)
• Application stage
(11 to 13 years)
• Lifelong utilization stage
(14 years and up)
