sensory and motor areas undergo major growth spurts during middle childhood.
- The two types of motor (movement) skills that children acquire are called "fine motor skills" and "gross motor skills."
- Using hands and fingers to control smaller things is a function of fine motor abilities. coordination is a component of gross motor skills.
- Synaptic remodeling, or pruning, is a natural process of maturation. Additionally, because each child has a different experience, the brain grows in large part as a result.
- More often utilized synapses tend to be kept, whereas less frequently used synapses are lost.
- The brain is driven by the motor system, which also drives sensory stimulation and feedback.
- These abilities must advance and grow in order to support behavior and academic learning.
- Children that struggle academically or behaviorally frequently have underdeveloped sensory and motor systems.
