Genie was left in extreme isolation. She was kept in a back bedroom,tied to a toilet. She received little stimulation of any kind and was fed baby food.She was given no visual or other sensory stimulation.This case shows that infancy and childhood are critical times for brain development. 2.What have scientists learned about the way that the brain develops in children? Describe how this development happens.
They have learned that there are critical periods for brain development. They discovered that parents fill a vital role in the development of their childs brain through their interactions with the child.Parents and caregivers must provide proper stimulation to help develop connections. Scientists believed that childrens brains were predetermined to a great extent in terms of how they would develop. However, scientists now know that an infants experiences help determine how connections are formed and which pathways will develop in the brain. Thus, rather than being predetermined, an infants brain is a work in progress, influenced not only by his or her genetics, but also the surrounding world. 3.Describe how speech generating devices work.
