In this age where science and education are so focused on the growing body of information regarding brain development, time spent watching TV has come under close scrutiny. Researchers have physical evidence exposing concerns about television viewing, once thought by many to be groundless. In a compelling article written by Jane Healy, Ph.D, author of the book, Explaining the Childhood Brain-Drain, Dr. Healy discusses the inability of the brain to create neuro pathways without experience. Neurons in the brain, responding to sensory stimuli, build new physical connections, called synapses, to neighboring cells. The synapses form networks that are the neurological foundations for reading comprehension, analytical thinking, sustained attention and problem-solving. Active interest and mental effort by the child are crucial to the formation of these networks. Every response to sights, sounds, feelings, smells, and tastes makes more connections. When a young child doesn't have the job done for him and displayed in front of him, his brain must go to work to create a picture using his imagination. This results in new connections as the brain analyses and solves problems to complete its understanding of a concept. Dr. Healy goes on to explain, The more work the brain does, the more it becomes capable of doing. Yet by ages three to five - the critical period for developing language and cognition - the average child is watching television approximately twenty-eight hours per week. An authority on hemispheric development at the University of Chicago, Dr. Jerre Levy, bio psychologist, says, When children commit time looking at TV, they're not spending time reading. When a child reads a novel, he has to self-create whole scenarios, he has to create images of who these people are, what their emotions are, what their tones of voice are, what the environment looks like, what the feeling of this environment is. These self-created scenarios are important, and television leaves no room for that creative process…Brains are designed to meet cognitive challenges. It's just like muscles: if you don't exercise them they wither. If you don't exercise brains, they wither. When a child of three to five years of age is watching TV, the opportunity to use her imagination to create images is greatly diminished. The images are already there for her on the screen. When the time comes to draw upon creative thinking skills in school and other settings, the connections in the brain required for the task aren't available. There is no prior experience for imagining what a scene in history the teacher is describing looks like or what an angry crowd in the scene might sound like. The child is scrambling to make sense of what she is hearing from the teacher, but there is no pathway in her brain for coming up with an image to inform understanding. Also of concern is the effect when images flash and change across the screen in rapid succession. There is a potential of further compromising children's ability to maintain focus and attention. While cutting out television entirely may prove unrealistic given societal views on TV, and perhaps unnecessary since some useful and educational television exists, there are ways to safeguard our children.
It is much easier to form healthy expectations when we start to do so early. It is important to keep in mind though that helping children at any point will help them throughout life. Children need to recognize that some of the expectations they set for themselves can get in the way of making better choices. Children hear a lot about what their friends watch on TV, and in general what they do with their time. Sometimes the result is that children come to expect that they deserve to spend a certain amount of time watching TV, because everybody else does. This expectation to watch can get in the way of exercising their minds in useful ways such as by playing, doing their homework and interacting with family members and friends. For instance, when children learn early the expectation at school age is they be the best students they can be, it is more likely their habit will be that TV comes only after homework is completed regularly and in a quality manner. Expectations often become habits. Dr. Jane Healy says of habits, Habits of the mind soon become structures of the brain. It is exciting when we begin early, with our preschoolers to create the expectation that quenching our thirst for knowledge and information through reading, conversation, investigation, playing, and other forms of getting answers is a pleasurable pursuit. In an effort to keep the Hot Topics articles presented here short and readable, other critical information concerning your child and television viewing will be presented in two weeks in, What about TV and my child's brain? Part II. |
