I had, on the table, six of the colour spools in pairs, that is two reds, two blues, two yellows. In the First Period, I placed one of the spools before the child, asking her to find the one like it. This I repeated for all three of the colours, showing her how to arrange them carefully in pairs. After this I passed to the Three Periods of Séguin. The little girl learned to recognise the three colours and to pronounce the name of each.
She was so happy that she looked at me for a long time, and then began to jump up and down. I, seeing her pleasure, said to her, laughing, "Do you know the colours?" and she replied, still jumping up and down, "Yes! YES!" Her delight was inexhaustible; she danced about me, waiting joyously for me to ask her the same question, that she might reply with the same enthusiasm, "Yes! Yes!"
Another important particular in the technique of sense education lies in isolating the sense, whenever this is possible. So, for example, the exercises on the sense of hearing can be given more successfully in an environment not only of silence, but even of darkness.
For the education of the senses in general, such as in the tactile, thermic, baric, and stereognostic exercises, we blindfold the child. The reasons for this particular technique have been fully set forth by psychology. Here, it is enough to note that in the case of normal children the blindfold greatly increases their interest, without making the exercises degenerate into noisy fun, and without having the child's attention attracted more to the bandage than to the sense-stimuli upon which we wish to focus the attention.
For example, in order to test the acuteness of the child's sense of hearing (a most important thing for the teacher to know), I use an empiric test which is coming to be used almost universally by physicians in the making of medical examinations. This test is made by modulating the voice, reducing it to a whisper. The child is blindfolded, or the teacher may stand behind him, speaking his name, in a whisper and from varying distances. I establish a solemn silence in the schoolroom, darken the windows, have the children bow their heads upon their hands which they hold in front of their eyes. Then I call the children by name, one by one, in a whisper, lighter for those who are nearer me, and more clearly for those farther away. Each child awaits, in the darkness, the faint voice which calls him, listening intently, ready to run with keenest joy toward the mysterious and much, desired call.
The normal child may be blindfolded in the games where, for example, he is to recognise various weights, for this does help him to intensify and concentrate his attention upon the baric stimuli which he is to test. The blindfold adds to his pleasure, since he is proud of having been able to guess.
The effect of these games upon deficient children is very different. When placed in darkness, they often go to sleep, or give themselves up to disordered acts. When the blindfold is used, they fix their attention upon the bandage itself, and change the exercise into a game, which does not fulfil the end we have in view with the exercise.
We speak, it is true, of games in education, but it must be made clear that we understand by this term a free activity, ordered to a definite end; not disorderly noise, which distracts the attention.
The following pages of Itard give an idea of the patient experiments made by this pioneer in pedagogy. Their lack of success was due largely to errors which successive experiments have made it possible to correct, and in part to the mentality of his subject.
"IV: In this last experiment it was not necessary, as in the one preceding, to demand that the pupil repeat the sounds which he perceived. This double work, distributing his attention, was outside the plane of my purpose, which was to educate each organ separately. I, therefore, limited myself to following the simple perception of sounds. To be certain of this result, I placed my pupil in front of me with his eyes blinded, his fists closed, and had him extend a finger every time that I made a sound. He understood this arrangement, and as soon as the sound reached his ear, the finger was raised, with a species of impetuosity, and often, with demonstrations of joy which left no doubt as to the pleasure the pupil took in these bizarre lessons. Indeed, whether it be that he found a real pleasure in the sound of the human voice, or that he had at last conquered the annoyance he at first felt on being deprived of the light for so long a time, the fact remains that more than once, during the intervals of rest, he came to me with his blindfold in his hand, holding it over his eyes, and jumping with joy when he felt my hands tying it about his head.
