Study Notes
Brain Development
- At age 6, the brain is about 90% of its adult weight.
- Between ages 2 and 6, children tend to experience rapid brain development.
- The cerebral cortex, which helps with thinking, strategizing, and controlling attention and emotions, matures during this period.
Physical Development
- The average height of a 6-year-old is not specified, but the average weight is around 45-50 pounds (20-23 kg).
Brain Structure
- The corpus callosum, a bundle of approximately 200 million nerve fibers, connects the two hemispheres of the brain.
- The prefrontal cortex, responsible for emotional control and strategic thinking, experiences greater development by age 6.
Language Development
- Between ages 3 and 6, the left hemisphere of the brain, responsible for language skills, experiences dramatic growth.
Milestones
- The brain reaches about 75% of its adult weight by age 3.
- By age 6, significant brain development has occurred, with the brain reaching 90% of its adult weight.
