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.
