Because the preadolescent years are, according to the child development researchers, the most formative, Joel P. Rhodes focuses on the cohort born between 1956 and 1970 who have never been quantitatively defined as a generation, but whose preadolescent world was nonetheless quite distinct from that of the "baby boomers." Rhodes examines how this group understood the historical forces of the 1960s as children, and how they made meaning of these forces based on their developmental age. He is concerned not only with the immediate imprint of the 1960s on their young lives, but with how their perspective on the era influenced them as adults.
