The physical changes of puberty are accompanied by changes in adolescent thinking and moral reasoning. As adolescent thinking becomes more logical and abstract, it is limited by adolescent egocentrism. Additionally, adolescent thinking is enhanced or discouraged by the schooling to which they are exposed. Schools that foster adolescent thinking and learning provide a variety of academic experiences and encourage complex interactions. Adolescents are receptive to their culture, to the models they see at home, in school and in mass media. Decisions regarding sexual behavior are influenced by their ability to think and reason, their values, and educational experience.
