The very earliest childhood memories might begin even earlier than anyone realized — including the one remembering, his or her parents and memory researchers. Four- to 13-year-olds in upstate New York and Newfoundland, Canada, probed their memories when researchers asked: “You know, some kids can remember things that happened to them when they were very little. What is the first thing you can remember? How old were you at that time?” The researchers then returned a year or two later to ask again about earliest memories — and at what age the children were when the events occurred.
