I wish first to emphasize my belief that where there is a great natural variation in excitability and emotionality in individuals, there is not nearly so much in races as we think, and that social heredity is tradition and cultural level plays the more important role in this. My friend and colleague, Dr. A. Warren Stearns, has made a study which shows that while the immigrant Italian is excitable and quick to anger and of revengeful reactions, his American-born descendent has so far controlled and changed this type of reaction that he does not especially figure in police records, in murders or assaults. My own studies of the second and especially the third generation Jew show there is an almost complete approach to the "American" type in emotional display, in what is known as poise. This third generation Jewish-American has dropped all the mannerisms of excitability in gesture and voice, and his adherence to good form includes that attitude of nonchalant humor so characteristic of the American. 1. The generally excitable, overemotional type. This type is more common in the Latin, Hebrew and Celtic races. In some respects it corresponds to the hypokinetic irritable, but it is not necessarily hypokinetic. The artistic type of person, so called, is of this group, but is, of course, talented as well. Talent need not be present, and there are persons of no artistic ability whatever who show a generalized, excitable-emotional temperament. All young children show the main traits of this type, and there is something essentially simple about all these folk, no matter how civilized or sophisticated they get to be. A. L., a woman of fifty, belongs to this group. She is a Jewess and now a widow. All of her life her character and temperament have been the same, and though her experiences have been varied she has not in any essential altered. This last is rather characteristic of the group, for experience has but little effect on their emotional reactions. A. L. cries very easily and readily, but her tears are easily dried and her joy is grotesquely childlike. She is readily frightened, worries without restraint and finds a melancholy satisfaction in the worst. At the same time, her fears do not persist and are easily dissipated by encouragement or good fortune. She is readily angered and "raises a row" with great facility and without restraint. For this reason her relatives and friends become panic-stricken when she becomes angry, for they know that she does not hesitate to make an embarrassing scene. In the efforts to conciliate her they are apt to give her her own way, as a result of which she is the proverbial spoiled child, capitalizing her weakness.
