From this it appears beyond a doubt that now (rather late in comparison with other children) the association of words heard with certain movements is established, inasmuch as upon acoustic impressions--at least upon combined impressions of hearing and of sight, which are repeated in like fashion--like movements follow, and indeed follow invariably with the expression of great satisfaction on the countenance. Yet this connection between the sensorium and the motorium is not yet stable, for there follows not seldom upon a command distinctly uttered, and without doubt correctly understood, the wrong movement--paramimy. Upon the question, "How tall?" the hands are put together for "Please," and the like. Once when I said, "How tall?" the child raised his arms a moment, then struck himself on the temples, and thereupon put his hands together, as if "rogue," and then "please," had been said to him. All three movements followed with the utmost swiftness, while the expression of face was that of a person confused, with wavering look. Evidently the child had _forgotten_ which movement belonged with the "tall," and performed all the three tricks he had learned, _confounding_ them one with another. This confounding of arm-raising, head-shaking, giving of the ring, putting the hands together, touching the head, is frequent. It is also to be noticed that some one of these five tricks is almost invariably performed by the child when some new command is given to him that he does not understand, as he perceives that something is required of him--the first conscious act of _obedience_, as yet imperfect.
