What you can remember from age 3 may help improve aspects of your life far into adulthood.

Children who have the ability to recall and make sense of memories from daily life—the first day of preschool, the time the cat died—can use them to better develop a sense of identity, form relationships and make sound choices in adolescence and adulthood, new research shows.

While the lives of many youngsters today are heavily documented in photos and video on social media and stored in families’ digital archives, studies suggest photos and videos have little impact. Parents play a bigger role in helping determine not just how many early memories children can recall, but how children interpret and learn from the events of their earliest experiences.

“Our personal memories define who we are. They bond us together,” says Robyn Fivush, a psychology professor at Emory University in Atlanta and an author of dozens of studies on the topic. Children whose parents encourage reminiscing and storytelling about daily events show better coping and problem-solving skills by their preteens, and fewer symptoms of depression, research shows.
