DEVELOPING THE OBSERVATION
The next step of development, after forming clear visual impressions, and closely allied to it, is the development of the faculty of observation. The eyes see, but the brain perceives. The sense organs bring a sensation to the brain where, by the act of perception, it is classified or identified as being like certain other objects and filed away in its proper place.
Recognition goes a step farther and places this object alongside of one particular mental image, which it resembles.
Standing by the gate in the twilight you see an object coming down the road. As it approaches you Perceive that it is a cow. As it comes closer you Recognize it as Neighbor Jones' cow. You Perceive that it is a cow, but you Recognize her as a certain cow, different from all others.
It is a fact that the eye may be perfect, and the nerve connecting it with the brain may be in good working order, and yet no impression may be received by the brain. Injury to that area of the brain which receives the impression from the eye may cause total blindness; at the same time the eye and nerves connecting it with the brain may be physically perfect.
When the brain is not injured, the same result is brought about by lack of Attention. The eye can look straight at an object and you do not perceive it. The brain does not accept any impression of it.
Attention is necessary that the sense impressions may be properly perceived and recognized; and this completed mental operation is commonly called Observation. Trained senses that react quickly make possible quick perception and recognition. The result is quick, accurate, and complete observation. Observation requires knowledge and it develops definite knowledge, but most people are poor observers. Help your children to be definite in their knowledge and to know what they know. How many can tell the different trees by name? How many legs has a spider, a fly, a bee, a butterfly?
It is a strange fact that the poorly educated are the best observers. Do not lose sight of the necessity of helping the child to form the habit of observation. It is the basis of common sense. Do not let him grow up ignorant of the common knowledge and experiences.
The faculty of observation is also the basis of science and of the success of specialists in every line. The story is told of a young man, who, having made up his mind to become a naturalist, went to a celebrated teacher in that line of study. The professor set the young man at work drawing a picture of a fish. The picture was soon finished and carried to the teacher for inspection, who, without looking up, said: "Draw it again." This seemed foolish to the young man, but he sat down and drew a new and better picture, which he again carried to the teacher for approval. This time the professor told him to go back and improve it and to wait until he should come to inspect it. The young scholar returned, did some more work on the picture and then pushed it back and waited. The professor did not come and so he started wandering restlessly around the room, thinking he had been forgotten.
Soon he became interested in studying the fish he had been drawing; he noticed several peculiarities of the eye which he added to his picture. This led him to a more careful study, and other details were noted and added. He then decided he could draw a better picture, so started all over again. After days had passed, the professor came in and glanced at the picture which the young man then realized was still only partially complete. For one year this young scholar was kept busy studying and drawing the fish, then the old professor told him: "You have learned the greatest lesson of the scientist, observation." This young man was Agassiz, who became America's foremost naturalist.
