Core Knowledge

Core Knowledge Using what you learned about read/write head development in Chapter 4, explain why intensive intervention for destitute children starting in the first 2 years has a great long-term impact on IQ than intervention at a later age. A childs header development is very(prenominal) critical in its first 2 years. A childs brain develops dramatically during the first 2 years. During the first two years neural fibers synapses plus at an outstanding pace.Because of developmenting neuron requires space for these cognitive structures a affect aspect of brain growth is that as synapses form many meet neurons die 20-80 portion, depending on the brain region. When a child is living in a low poverty environment it affects the childs brain since the neurons are not being wound up by their caregivers. Looking at a caregiver who does not interact with a child a young age the child will have less interaction with a person. This correlates with a childs IQ. When neurons are seld om stimulated they lose their synapses in a process called synaptic pruning.About 40 percent synapses are pruned during childhood. About half of brains volumes consist of gilal cells which are responsible for myelination. The growth through the lifespan moderate talks about children who are follow have a greater chance to better nutrition and health. The book also talks about stress. Chronic stress of early take orphanage rearing disrupts the brains capacity to manage stress, with long-term physical and psychological consequences. Reference Berk, L.
