Compared adolescents' (14 to 20 years) and young adults' (21 to 37 years) wisdom-related knowledge and judgment related to difficult and ill-defined life dilemmas. Rated responses along five wisdom criteria. Found that adolescents performed at lower levels than young adults but also demonstrated substantial age increments in performance.…

Examined intraindividual and interindividual differences in self-esteem among 142 rural adolescents during a four-year period encompassing the transition to high school.

The development of political thinking during adolescence was studied by interviewing 463 suburban and urban schoolchildren of average intelligence in grades 6, 8, 10, and 12. Each subject was interviewed individually by means of a Piaget-type questionnaire. Analysis of the questionnaire responses revealed a very distinctive developmental pattern.…
