An explosion of research in neuroscience and other developmental sciences shows us that the basic architecture of a child’s brain is constructed through an ongoing process that begins before birth and continues through adulthood. Like the construction of a home, the building process begins with laying the foundation, framing the rooms, and wiring the electrical system in a predictable sequence. Early experiences literally shape how the brain gets built. A strong foundation in the early years increases the probability of positive outcomes. A weak one will require remedial education, clinical treatment, or other interventions that are less effective and more costly than providing crucial brain-building interactions early in life.
