In the beginning all the brain does is to store the simple sense impressions. The baby sees his mother many times before he recognizes her. The eye nerve carries to the brain the picture of the mother's face and stores it there. Soon the brain perceives the similarity and the child recognizes her. The fact that in some way the brain retains the first, second, third, etc., impressions becomes the foundation of recognition. If the sense nerve failed to carry the image of the face there would be no comparison and no recognition. Without sense impression there can be no knowledge. Imperfect sense impressions can only result in imperfect knowledge. Each set of sense nerves carries its impressions to a different area of the brain. Each set has a distinct and localized memory. The ear memory is the auditory memory. There is the gustatory memory of taste; the olfactory memory of smell, and the tactual memory of touch. The visual memory is the most accurate and lasting. The nerves connecting the eyes with the brain are many times larger than those of the other sense organs. Psychological tests have also proven the eye to be the most accurate of all the senses. Next to the eye comes the ear in both strength and exactness. Sense Training Games The training of the senses, important and necessary as it is, can be accomplished in a most entertaining and pleasant manner. The playing of games, so necessary in the life of children, can in most cases be used as the agency to gain this result. Game of Hide the Watch You can entertain your children for an hour with this game and at the same time, even without their knowledge, be training one of their most important senses. Go into a quiet room and hide a watch where it will be out of sight but in a place where the ticking will be plainly audible. If the children are small it will be well to start with a small clock, or a watch which ticks loudly. Now let the children come into the room and, standing perfectly still, try to locate the watch by hearing it tick. Let them move around, but very quietly, so as not to disturb the others; or let all move at one time. When one of them has located the watch allow that child to remain and assist you in hiding it for the others. A record can be kept to see who finds the watch the most often. One child must not be allowed to move noisily, or in any way disturb the efforts of the others. See to it that they use their ears and not their eyes; it will even be well to blindfold them. Results of Sense Training That the senses can be trained every one will at once admit. The world is full of examples, as the Indian savage with his keen sight and hearing. You may think this a natural born ability but there are many examples to prove the contrary. The American scouts, some of whom have gone into the Indian country when they were grown men, have become almost as proficient as the Indians themselves.
