There's a longstanding belief that all of our cognitive abilities decline after early adulthood. Turns out that when it comes to determining the peak of our own cognitive abilities, it's a lot more complicated than we may have thought. New research suggests that some aspects of intelligence peak at different times over the course of our lives.

Laura Germine is a postdoctoral researcher in psychiatric genetics at Massachusetts General Hospital and Harvard Medical School. Instead of bringing volunteers into the lab, she uses online games at to run experiments.
