this cross-section activity now tends to unity, so that all parts of the brain energize together. In a brain with this switchboard function well organized, each reaction has grown independent of its own stimulus and may result from any stimulation, and each act, e.g., a finger movement of a peculiar nature, may tire the whole brain. This helps us to understand why brain-workers so often excel laborers not only in sudden dynamometric strength test, but in sustained and long-enduring effort. In a good brain or in a good machine, power may thus be developed over a large surface, and all of it applied to a small one, and hence the dangers of specialization are lessened in exact proportion as the elements of our ego are thus compacted together. It is in the variety and delicacy of these combinations and all that they imply, far more than in the elements of which they are composed, that man rises farthest above the higher animals; and of these powers later adolescence is the golden age. The aimless and archaic movements of infancy, whether massive and complex or in the form of isolated automatic tweaks or twinges, are thus, by slow processes of combined analysis and synthesis, involving changes as radical as any in all the world of growth, made over into habits and conduct that fit the world of present environment.
But, thirdly, this long process carried out with all degrees of completeness may be arrested at any unfinished stage. Some automatisms refuse to be controlled by the will, and both they and it are often overworked. Here we must distinguish constantly between (1) those growing rankly in order to be later organized under the will, and (2) those that have become feral after this domestication of them has lost power from disease or fatigue, and (3) those that have never been subjugated because the central power that should have used them to weave the texture of willed action--the proper language of complete manhood--was itself arrested or degenerate. With regard to many of these movements these distinctions can be made with confidence, and in some children more certainly than in others. In childhood, before twelve, the efferent patterns should be developed into many more or less indelible habits, and their colors set fast. Motor specialties requiring exactness and grace like piano-playing, drawing, writing, pronunciation of a foreign tongue, dancing, acting, singing, and a host of virtuosities, must be well begun before the relative arrest of accessory growth at the dawn of the ephebic regeneration and before its great afflux of strength. The facts seem to show that children of this age, such as Hancock[10] described, who could not stand with feet close together and eyes closed without swaying much, could not walk backward, sit still half a minute, dress alone, tie two ends of a string together, interlace slats, wind thread, spin a top, stand on toes or heels, hop on each foot, drive a nail, roll a hoop, skate, hit fingers together rapidly in succession beginning at the little finger and then reversing, etc., are the very ones in whom automatisms are most marked or else they are those constitutionally inert, dull, or uneducable.
In children these motor residua may persist as characteristic features of inflection, accent, or manners; automatisms may become morbid in stammering or stuttering, or they may be seen in gait, handwriting, tics or tweaks, etc. Instead of disappearing with age, as they should, they are seen in the blind as facial grimaces uncorrected by the mirror or facial consciousness, in the deaf as inarticulate noises; and they may tend to grow monstrous with age as if they were disintegrated fragments of our personality, split off and aborted, or motor parasites leaving our psycho-physic ego poorer in energy and plasticity of adaptation, till the distraction and anarchy of the individual nature becomes conspicuous and pathetic.
At puberty, however, when muscle habits are so plastic, when there is a new relation between quantity or volume of motor energy and qualitative differentiation, and between volitional control and reflex activities, these kinetic remnants strongly tend to shoot together into wrong aggregates if right ones are not formed. Good manners and correct motor form generally, as well as skill, are the most economic ways of doing things; but this is the age of wasteful ways, awkwardness mannerisms, tensions that are a constant leakage of vital energy, perhaps semi-imperative acts, contortions, quaint movements, more elaborated than in childhood and often highly anesthetic and disagreeable, motor co?rdinations that will need laborious decomposition later. The avoidable factor in their causation is, with some modification, not unlike that of the simpler feral movements and faulty attitudes, carriage, and postures in children; viz., some form of overpressure or misfit between environment and nature. As during the years from four to eight
