Kids Talk : The brain seeks to control stress
Posted on Monday, August 4, 2008
Brain researchers believe that a newborn’s brain creates neurons at a rate of more than a quarter a million per minute. The young brain grows and absorbs information without evaluating, filtering or giving priority to the information. The brain receives each event with the same import as every other experience.
The young brain hasn’t learned how to filter critical information for survival, as true or false, real or fantasy, or good or bad. The brain receives violence, disrespect, hurtful language and physical abuse with the same sense of reality as calmness, kindness, positivity and gentleness. Loud noises, harsh lighting, disruptions, irregular schedules, though, are among the activities that create stress in the young child and communicate to the brain and body to be on danger alert. The brain seeks to control stress in the young child and begins to create a brain structure based on acceptance or avoidance of the stimuli in the child’s environment.
During the first six years of life, the child is in a sensitive period for learning about human relationships and what it means to be human. When the environment is such that the brain perceives the child’s surroundings as hurtful, brain structure begins to reflect that perception by pruning down neuron development for hearing, touch, hunger, etc. to compensate for the stressful sensory overload. Likewise, if the environment is calm and nurturing, the brain develops to accept and grow in response to that life-affirming presence.
Our electronic baby sitters may contribute more to children’s misperceptions of what it means to be human than the actual experience of living with people.
Consider the following facts:
• 36 percent of all children have TVs in their bedrooms;
• 50 percent of households have three or more TVs;
• 49 percent of households have video-game players;
• 73 percent of households have computers; and • 99 percent of children live in a home with a TV set. The pervasive nature of electronic media in our children’s lives is substantial. Children’s Saturday-morning programs have an average of 20 to 25 violent acts per hour. The content of the media-violence and abusive language affects the stress level of a child, thus the development of the brain and personality. The brain during the first two years of life is absorbing information as if everything experienced were normal, and brain development responds accordingly. If normal is loud, violent or abusive, and not the expected loving interaction with adults, the child’s brain development begins to incorporate defensive mechanisms that work against the child’s natural tendencies to be curious and seek out new, challenging and meaningful experiences — the core of true learning. We need to minimize the amount of distress in our young children’s environments. Noise levels, lighting, abrupt disruptions and the threat of violence from television or others need to be managed by the adults in the child’s life in order to maximize healthy brain growth. If you have a television in your home, step outside sometime today while the television is playing, and look through a window at the television screen. Imagine that you are a newborn, a 2-year-old, a 3-year-old. What are the lighting, the changes in images and the type of images conveying to a child’s mind ? Think about how your child’s brain is reacting to these stressors and how you can minimize them. Remember, a child’s brain grows in response to its environment.
