Key Concepts and Theories

• Schema theory proposes that motor learning involves the formation and refinement of generalized motor programs (schemas) that can be adapted to various contexts and tasks
• Dynamical systems theory emphasizes the role of self-organization and emergent behavior in motor skill acquisition and control
