The self-social-environmenatl orientations of twenty-nine 12-year old children of poverty and children of affluence in Mexico City were obtained through 12 photographs taken by these children in response to the question "Who Are You?" The five findings which differentiated the children of affluence from the children of poverty pertained to the self, activities, books, games, and range of orientations. Some of the most extreme differences were observed between affluent boys and poverty girls. The girls of poverty showed no photographs of self, activities, games, or toys, whereas every affluent boy showed at least one photograph which included the self, with the most photographs involving music and art activities, lessons, possessions, games and toys, and the least photographs showing others, groups, and religion. Girls of poverty showed the least possessions and lowest range of orientations but most of crowds (more than three people), holding a child, other people, and groups. Boys best represented the effects of affluence and girls best represented effects of poverty. The depicted psychological niches of the affluent represented a circumscribed, high-potential, self-reinforcing system. The psychological niches of the children of poverty (particularly girls) represented a limited system of support within an extended group. (Author/CM)
