Document Summary
Babies motor achievements have a powerful effect on their social relationships. Gross-motor development control over actions that help infants get around in the environment, such as crawling, standing, and walking. Fine-motor development smaller movements, such as reaching and grasping. According to the dynamic systems theory of motor development, mastery of motor skills involves acquiring increasingly complex systems of action. Each new skill is a joint product of the following factors: Ex) control of the head and upper chest combine into sitting with support kicking, 3 the goals the child has in mind. The broader physical environment also influences motor skills. Ex) infants with stairs in their home learn to crawl up stairs at an earlier age. As movements are repeated thousands of times, they promote new synaptic connections in the brain that govern motor patterns. Dynamic systems theory shows us why motor development cannot be genetically determined.
