The brain is basically built from bottom up. Firstly the brain builds basic circuits that are responsible for basic skills and then more complex circuits are built on top of those basic circuits as we develop more complex skills. Biologically the brain is prepared to be shaped by experience. It is expecting the experiences that a young child has to literally influence the formation of its circuitry. it is built into our biology. The interaction between genetics and experience that shapes brain architecture is embedded in the reciprocal relationship that children have with their adults in their life. By that we mean we refer to as serve return in nature of children interation with their adults. Development and impact of expericen on development is not one-way street; it is a back and forth interaction. The brain is a highly intergrated organ which has multiple sections that specialize different processes so we have parts of the brain that involve more cognitive function and other parts that are involved in processing the emotion and parts of involving seeing and hearing. So if a child is emotionally kind of well put together and socially competent, that will have a positive and productive effect on learning. If a child is preoccpied with fears or anxiety or is dealing with considerable stress, no matter how intellectually gifted that child might be, it is his learning (that) is gonna be impared by that kind of emotion interference.
