It's a study of adult lifespan development and when it was started in 1938, it was actually radical to study normal development for two reasons. One is that most of what had been studied was about what goes wrong in development, which we still do because we want to try to help people who are having developmental problems.

So that makes a lot of sense, but to study what goes right in development, that was unheard of. The other thing is that for a long time, we certainly thought about children as developing because you can watch children change every day. That change happens so fast, but many people thought that once you got to be in your 20s, you were kind of done with development. You found a partner, you found a line of work, you were set with regard to your personality, and that was it, then you just lived your life.

And of course, now we understand that there's so much that changes and develops through the course of adult life, but my predecessors (I'm the fourth director) were really, insightful in their understanding of how much there was to learn about all the changes that happen across the adult lifespan.
