It wasn't very long ago that children's entertainment would be playing with objects, being told or read stories, or perhaps listening to the radio during a significant portion of each child's early years. With the advent of television, videos and computers, these tactile and oral worlds are often left behind. Children who are frequently exposed to television, videos and computer games in the first seven years of life have been found to develop pathways in the brain that later are significantly deficient in reading, studying and socialization skills. It happends quickly: Four hours per day of television translates to twenty-eight hours per week or two months per year. Dr. Jane M. Healy is an educational psychologist with expertise in developmental psychology, and specialist in the brain development of young children. Her recent books, "Endangered Minds," and "Failure to Connect" discuss how television, videos and computers affect the minds of children. I spoke with Dr. Healy by phone from her home in Colorado and asked her to begin by describing the role of media on the developing mind of a young child.
