Question

Quizplus · Accepted Answer

Universal high school attendance became a common experience for American teens in the mid-20th century, leading to the recognition and definition of adolescence as a distinct life stage. This was encouraged by President Franklin Roosevelt and other educational reformers during the Great Depression and World War II. While the work of Freud and Piaget may have influenced our understanding of adolescence, they did not directly lead to the recognition of it as a separate life stage. The rebellion of the baby boom generation occurred later and was a cultural phenomenon rather than a defining moment in the recognition of adolescence.
