Intellectual capacity is not fixed at birth. In fact, the brain is the least developed organ at birth.
Predictable, loving, responsive care has a direct positive impact on brain development.
By three years of age, a child's brain has grown to about 90 percent of its adult size.
By working closely with a child, an adult using specific teaching tools and techniques can significantly influence the way a child's brain develops.
When a child is born he or she has about 100 billion nerve cells, most of them unconnected. Interactions during the early months of life result in the formation of brain structures that develop in response to specific learning activities. The stimuli provided by a child's early, daily environment, especially the people in his or her life, affect how these intricate connections are wired.
