THE INTERESTS OF EARLY CHILDHOOD.--The interests of early childhood are chiefly connected with ministering to the wants of the organism as expressed in the appetites, and in securing control of the larger muscles. Activity is the preeminent thing--racing and romping are worth doing for their own sake alone. Imitation is strong, curiosity is rising, and imagination is building a new world. Speech is a joy, language is learned with ease, and rhyme and rhythm become second nature. The interests of this stage are still very direct and immediate. A distant end does not attract. The thing must be worth doing for the sake of the doing. Since the young child's life is so full of action, and since it is out of acts that habits grow, it is doubly desirous during this period that environment, models, and teaching should all direct his interests and activities into lines that will lead to permanent values. THE INTERESTS OF LATER CHILDHOOD.--In the period from second dentition to puberty there is a great widening in the scope of interests, as well as a noticeable change in their character. Activity is still the keynote; but the child is no longer interested merely in the doing, but is now able to look forward to the end sought. Interests which are somewhat indirect now appeal to him, and the how of things attracts his attention. He is beginning to reach outside of his own little circle, and is ready for handicraft, reading, history, and science. Spelling, writing, and arithmetic interest him partly from the activities involved, but more as a means to an end. Interest in complex games and plays increases, but the child is not yet ready for games which require team work. He has not come to the point where he is willing to sacrifice himself for the good of all. Interest in moral questions is beginning, and right and wrong are no longer things which may or may not be done without rebuke or punishment. The great problem at this stage is to direct the interest into ways of adapting the means to ends and into willingness to work under voluntary attention for the accomplishment of the desired end. THE INTERESTS OF ADOLESCENCE.--Finally, with the advent of puberty, comes the last stage in the development of interests before adult life. This period is not marked by the birth of new interests so much as by a deepening and broadening of those already begun. The end sought becomes an increasingly larger factor, whether in play or in work. Mere activity itself no longer satisfies. The youth can now play team games; for his social interests are taking shape, and he can subordinate himself for the good of the group. Interest in the opposite sex takes on a new phase, and social form and mode of dress receive attention. A new consciousness of self emerges, and the youth becomes introspective. Questions of the ultimate meaning of things press for solution, and what and who am I, demands an answer.
