It was Modern American Literature, 1915-60; Dr. Matthews introduced the course's theme: Adolescence. To introduce adolescence, she had us read the introduction to Adolescence. The author? G. Stanley Hall. He not only introduced psychology to America, but he advanced child development. From what I understand, until the late 19th century, most people thought of children and teens as miniature adults. Hall placed teens apart from both; he coined the term "storm and stress."
So, thanks G. Stanley Hall! You have given us a way to understand what teens don't know. Do you have an interesting story from your youth? If you tell, I'll tell one too.
