While during the concrete operational stage, children would be manipulating symbols in a logical thought. On their formal operational stage, intelligence is related to the abstract concepts. By understanding the stages of cognitive development on children, it would give parents an understanding on when to introduce children into exercises that will develop their cognitive skills. The simple reason is that neurons need more oxygen than any other body part to function well. Study results have shown that physical exercise provides enough blood flow to meet that need. It also provides glucose and other nutritional needs for the neurons. Among other things, it had also been proven that exercise increases cognitive brain functions, enhances learning, boosts memory and keeps away neurodegenerative diseases. Meanwhile, a research led by Psychology professor John Gabrieli from the Stanford University, discovered that dyslexia could actually be connected with a defect on a neuron function. Those who have difficulty in reading would often have an abnormal function of the neuron s myelin. By understanding this neurobiological aspect of dyslexia, the researchers were able to design a kind of training which helped dyslexics become better readers after eight weeks of the training. No age limit The body may show some signs of wear and tear and the fatigue that goes with them. Exercises have to be modified to fit the person s age doing the physicals. The brain does not have limits. Brain training and other mental calisthenics is a one-size-fits-all commodity, except perhaps for the very young and the very old. Another simple practice which would help in developing your right part of the brain association with visualization. Getting into brain games would not only increase your intelligence, but also research showed that it could improve memory, mood and focus. It could help you improve you concentration which can lead to quicker response and thinking. Brain Training The Child One of the most amazing organs of the body is the brain, and the brain is at its most marvelous stage during a child s wonder years. At age 3 onwards till adolescence, brain training a child is at its most effective because this is the time when the brain can absorb information at incredible speed and ease.
