Many facts tend to bear out this position. My child cried in the dark when I handled her, although I imitated the nurse's movements as closely as possible. She tolerated a strange presence so long as it remained quietly in its place; but let it move, and especially let it usurp any of the pieces of movement-business of the nurse or mother, and her protests were emphatic. The movements tended to bring the strange elements of a new face into the vital association, pain-movement-pleasure, and so to disturb its familiar course; this constituted it a strange "personality."

It is astonishing, also, what new accidental elements may become parts of this association. Part of a movement, a gesture, a peculiar habit of the nurse, may become sufficient to give assurance of the welcome presence and the pleasures which the presence brings. Two notes of my song in the night stood for my presence to H., and no song from any one else could replace it. A lighted match stopped the crying of E. for food in her fourteenth week, although it was but a signal for a process of food preparation lasting several minutes; and a simple light never stopped her crying under any other circumstances.

2. With this first start in the sense of personality we find also the beginning of the recognition of different personalities. It is evident that the sense of another's presence thus felt in the infant's consciousness rests, as all associations rest, upon regularity or repetition; his sense of expectancy is aroused whenever the chain of events is started. This is soon embodied largely in two indications: the face and the voice. But it is easy to see that this is a very meagre sense of personality; a moving machine which brought pain and alleviated suffering might serve as well. So the child begins to learn, in addition, the fact that persons are in a measure individual in their treatment of him; that their individuality has elements of uncertainty or irregularity about it. This growing sense is very clear to one who watches an infant in its second half year. Sometimes its mother gives it a biscuit, but sometimes she does not. Sometimes the father smiles and tosses the child; sometimes he does not. Even the indulgence of the grandmother has its times and seasons. The child looks for signs of these varying moods and methods of treatment; for his pains of disappointment arise directly on the basis of that former sense of regular personal presence upon which his expectancy goes forth.

This new element of the child's sense of persons becomes, at one period of its development, quite the controlling element. His action in the presence of the persons of the household becomes hesitating and watchful. Especially does he watch the face, for any expressive indications of what treatment is to be expected; for facial expression is now the most regular as well as the most delicate indication. Special observations on H.'s responses to changes in facial expression up to the age of twenty months showed most subtle sensibility to these differences; and normal children all do. Animals are also very expert at this.

All through the child's second year, and longer, his sense of the persons around him is in this stage. The incessant "why?" with which he greets any action affecting him, or any information given him, is witness to the simple puzzle of the apparent capriciousness of persons. Of course he can not understand "why"; so the simple fact to him is that mamma will or won't, he knows not beforehand which. He is unable to anticipate the treatment in detail, and he has not of course learned any principles of interpretation of the conduct of father or mother lying back of the details.

But in all this period there is germinating in his consciousness—and this very uncertainty is an important element of it—the seed of a far-reaching thought. His sense of persons—moving, pleasure-or-pain-giving, uncertain but self-directing persons—is now to become a sense of agency, of power, which is yet not the power of the regular-moving door on its hinges or the rhythmic swinging of the pendulum of the clock. The sense of personal agency is now forming, and it again is potent for still further development of the social consciousness. It is just here, I think, that imitation becomes so important in the child's life. This is imitation's opportunity. The infant watches to see how others act, because his own weal and woe depends upon this "how"; and inasmuch as he knows not what to anticipate, his mind is open to every suggestion of movement. So he falls to imitating. His attention dwells upon details, and by the principle of adaptation which imitation expresses, it acts out these details for himself.

It is an interesting detail, that at this stage the child begins to grow capricious himself; to feel that he can do whatever he likes. Suggestion begins to lose the regularity of its working, for it meets the child's growing sense of his own agency. The youthful hero becomes "contrary." At this period it is that obedience begins to grow hard, and its meaning begins to dawn upon the child as the great reality. For it means the subjection of his own agency, his own liberty to be capricious, to the agency and liberty of some one else.

3. With all this, the child's distinction between and among the persons who constantly come into contact with him grows on apace, in spite of the element of irregularity of the general fact of personality. As he learned before the difference between one presence and another, so now he learns the difference between one character and another. Every character is more or less regular in its irregularity. It has its tastes and modes of action, its temperament and type of command. This the child learns late in the second year and thereafter. He behaves differently when the father is in the room. He is quick to obey one person, slow to obey another. He cries aloud, pulls his companions, and behaves reprehensibly generally, when no adult is present who has authority or will to punish him. This stage in his "knowledge of man" leads to very marked differences of conduct on his part.

4. He now goes on to acquire real self-consciousness and social feeling. This stage is so important that we may give to it a separate heading below.

It may not be amiss to sum up what has been said about Personality-Suggestion. It is a general term for the information which the child gets about persons. It develops through three or four roughly distinguished stages, all of which illustrate what is called the "projective" sense of personality.[2] There is, 1. A bare distinction of persons from things on the ground of peculiar pain-movement-pleasure experiences. 2. A sense of the irregularity or capriciousness of the behaviour of these persons, which suggests personal agency. 3. A distinction, vaguely felt perhaps, but wonderfully reflected in the child's actions, between the modes of behaviour or personal characters of different persons. 4. After his sense of his own agency arises by the process of imitation, he gets what is really self-consciousness and social feeling.
