Memories before age two are probably not true memories, but rather are fictional memories that we've stored as a result of other people telling us stories about ourselves. If your father talked at length about one time when he was pushing your stroller through a park and a dog came and licked your face, you may eventually start to "remember" this event as if it were your own memory. The first time you heard it, it was definitely new. The second time it feels familiar. The third time it feels so familiar that you wonder if maybe you do remember it. Then you think yeah, you probably do recall that. And so on and so forth, until eventually you think of it as a genuine memory. Half of the pre-age-two memories in this survey involved a baby carriage, and another 30 percent were about some kind of family relationship, which means they could have easily been implanted by a family member's story. People with first memories from the average age have more of a mix.
