It is then this preference for one particular kind of mental imagery, and that the motor, or muscular kind, which gives this type of child his peculiarity in this more psychological period. When we pass from the mere outward and organic description of his peculiarities, attempted above in the case of very young children, and aim to ascertain the mental peculiarity which accompanies it and carries on the type through the individual's maturer years, we see our way to its meaning. The fact is that a peculiar kind of mental imagery tends to swell up in consciousness and monopolize the theatre of thought. This is only another way of saying that the attention is more or less educated in the direction represented by this sort of imagery. Every time a movement is thought of, in preference to a sound or a sight which is also available, the habit of giving the attention to the muscular equivalents of things becomes more firmly fixed. This continues until the motor habit of attention becomes the only easy and normal way of attending; and then the person is fixed in his type for one, many, or all of his activities of thinking and action.
So now it is no longer difficult to see, I trust, why it is that the child or youth of this sort has the characteristics which he has. It is a familiar principle that attention to the thought of a movement tends to start that very movement. I defy any of my readers to think hard and long of winking the left eye and not have an almost irresistible impulse to wink that eye. There is no better way to make it difficult for a child to sit still than to tell him to sit still; for your words fill up his attention, as I had occasion to say above, with the thought of movements, and these thoughts bring on the movements, despite the best intentions of the child in the way of obedience. Watch an audience of little children—and children of an older growth will also do—when an excited speaker harangues them with many gestures, and see the comical reproduction of the gestures by the children's hands. They picture the movements, the attention is fixed on them, and appropriate actions follow.
It is only the generalizing of these phenomena that we find realized in the boy or girl of the motor type. Such a child is constantly thinking of things by their movement equivalents. Muscular sensations throng up in consciousness at every possible signal and by every train of association; so it is not at all surprising that all informations, instructions, warnings, reproofs, suggestions, pass right through such a child's consciousness and express themselves by the channels of movement. Hence the impulsive, restless, domineering, unmeditative character of the child. We may now endeavour to describe a little more closely his higher mental traits.
1. In the first place the motor mind tends to very quick generalization. Every teacher knows the boys in school who anticipate their conclusions, on the basis of a single illustration. They reach the general notion which is most broad in extent, in application, but most shallow in intent, in richness, in real explaining or descriptive meaning. For example, such a boy will hear the story of Napoleon, proceed to define heroism in terms of military success, and then go out and try the Napoleon act upon his playfellows. This tendency to generalize is the mental counterpart of the tendency to act seen in his conduct. The reason he generalizes is that the brain energies are not held back in the channels of perception, but pour themselves right out toward the motor equivalents of former perceptions which were in any way similar; then the present perceptions are lost in the old ones toward which attention is held by habit, and action follows. To the child all heroes are Napoleons because Napoleon was the first hero, and the channels of action inspired by him suffice now for the appropriate conduct.
2. Such a scholar is very poor at noting and remembering distinctions. This follows naturally from the hasty generalizations which he makes. Having once identified a new fact as the same as an old one, and having so reached a defective sense of the general class, it is then more and more hard for him to retrace his steps and sort out the experiences more carefully. Even when he discovers his mistake, his old impulse to act seizes him again, and he rushes to some new generalization wherewith to replace the old, again falling into error by his stumbling haste to act. The teacher is oftener perhaps brought to the verge of impatience by scholars of this class than by any others.
3. Following, again, from these characteristics, there is a third remark to be made about the youth of this type; and it bears upon a peculiarity which it is very hard for the teacher to estimate and control. These motor boys and girls have what I may characterize as fluidity of the attention. By this is meant a peculiar quality of mind which all experienced teachers are in some degree familiar with, and which they find baffling and unmanageable.
By "fluidity" of the attention I mean the state of hurry, rush, inadequate inspection, quick transition, all-too-ready-assimilation, hear-but-not-heed, in-one-ear-and-out-the-other habit of mind. The best way to get an adequate sense of the state is to recall the pupil who has it to the most marked degree, and picture his mode of dealing with your instructions. Such a pupil hears your words, says "yes," even acts appropriately so far as your immediate instructions go; but when he comes to the same situation again, he is as virginly innocent of your lesson as if his teacher had never been born. Psychologically, the state differs from preoccupation, which characterizes quite a different type of mind. The motor boy is not preoccupied. Far from that, he is quite ready to attend to you. But when he attends, it is with a momentary concentration—with a rush like the flow of a mountain stream past the point of the bank on which you sit. His attention is flowing, always in transition, leaping from "it to that," with superb agility and restlessness. But the exercise it gains from its movements is its only reward. Its acquisitions are slender in the extreme. It illustrates, on the mental plane, the truth of the "rolling stone." It corresponds, as a mental character, to the muscular restlessness which the same type of child shows in the earlier period previously spoken of.
The psychological explanation of this "fluid attention" is more or less plain, but I can not take space to expound it. Suffice it to say that the attention is itself, probably, in its brain seat, a matter of the motor centres; its physical seat both "gives and takes" in co-operation with the processes which shed energy out into the muscles. So it follows that, in the ready muscular revivals, discharges, transitions, which we have seen to be prominent in the motor temperament the attention is carried along, and its "fluidity" is only an incident to the fluidity of the motor symbols of which this sort of a mind continually makes use.
Coming a little closer to the pedagogical problems which this type of pupil raises before us, we find, in the first place, that it is excessively difficult for this scholar to give continuous or adequate attention to anything of any complexity. The movements of attention are so easy, the outlets of energy, to use the physical figure, so large and well used, that the minor relationships of the thing are passed over. The variations of the object from its class are swept away in the onrush of his motor tendencies. He assumes the facts which he does not understand, and goes right on to express himself in action on these assumptions. So while he seems to take in what is told him, with an intuition that is surprisingly swift, and a personal adaptation no less surprising, the disappointment is only the more keen when the instructor finds the next day that he has not penetrated at all into the inner current of this scholar's mental processes.
Again, as marked as this is in its early stages, the continuance of it leads to results which are nothing short of deplorable. When such a student has gone through a preparatory school without overcoming this tendency to "fluid attention" and comes to college, the instructors in the higher institutions are practically helpless before him. We say of him that "he has never learned to study," that he does not know "how to apply himself," that he has no "power of assimilation." All of which simply means that his channels of reaction are so formed already that no instruction can get sufficient lodgment in him to bring about any modification of his "apperceptive systems." The embarrassment is the more marked because such a youth, all through his education period, is willing, ready, evidently receptive, prompt, and punctual in all his tasks.
