That team reported that both the genes and environment played important roles in determining the intelligence of the child. This stands to reason because the quality of the brain cells is determined both by the genes and by pre-natal nutrition. Stimulation of these cells depends on the environment including the effort of the parents. Proper stimulating atmosphere for casual learning alone will update the I.Q. of the child. It now stands established that if your baby as a grown up child, talk to him in proper language, cut jokes, make fun, laugh, sing, dance to him, read books to him and all that when he cannot talk and sometimes not even respond, such parental attention helps in constructing the complex brain circuitry so essential to intellectual development.
Early stimulation develops intelligence in the child.
It would be appropriate to provide such stimulation relating to senses of smell, taste and touch, also showing how various tastes touches and smells are different. Not only will it amuse the child but very soon the child will start copying by making similar faces. That will ensure that the wiring of the brain cells has been effectively accomplished. Another visual game could be to have a few coloured ribbons tied and kept near a window or a fan so that the child could watch ribbons fly in the breeze. Occasionally the fan could be stopped and occasionally he could touch the ribbons.
