"As a general principle, the smaller the group of individuals who are in competition with one another, and the narrower the range of their interests, the more intense will be the jealous attitudes developed. As the group increases in membership and their interests and activities become more varied, particular competitors normally come to occupy a less and less important place in any one individual's attention. It is as though the energy which in a restricted situation finds an outlet in one channel, perhaps, is discharged through various channels when the circle of persons and the range of interests to be reacted upon are enlarged. It is probable that most strictly social attitudes become less pronounced, though they are likely to become more habitual, according as the occasions which call them forth are multiplied. "This principle has an interesting application to the child when he enters school. His new personal environment makes such demands upon his attention and energy, in order that he may take the first steps in adjustment thereto, that the jealous attitudes are not aroused for some time, though they are liable to appear as he begins to feel at home in the new group. The beginner is usually in the learning or adaptive attitude; he is never, at the outset, resentful towards individuals in the group who may secure greater attention than himself from the teacher or his associates. The novice in school seeks, above everything else, to win the favour of those who, for any reason, are prominent in the group. He does not normally oppose his personality to that of any one who stands well with the crowd, or who has the support of tradition in his particular expressions.... "As the child grows to feel at ease in adjustment to the situations presented in the school, he commences to assume attitudes of disapproval, as well as approval, of the expressions of his associates, and even of the teacher. In due course--often by the fourth year in school, possibly earlier--he begins to manifest some feeling of jealousy towards those of his group who attain greater prominence in the work of the school than he does himself. However, according to the observations of the present writer, this feeling is not a dominant one at any period in the elementary school, except in the case of particular children who are displeased at any distinction in recitations or in conduct attained by their classmates.
