After a lot of research, scientists have come to the following conclusions: children's memory before the age of five is mainly short-term memory, which can save information in a few hours or even less; From the age of six to nine, children's memory capacity and duration gradually increase, and they can remember more information and keep it for a longer time; After the age of ten, children's long-term memory ability has been significantly improved. They can remember and save more and more complex information and use it in different ways.
It should be noted that each child's memory ability is different, so there is no exact age to define what kind of information a child can remember for a long time. But for parents, regardless of their children's age, they should provide a good and rich learning and living environment to help children fully develop their memory ability and stimulate their hobbies, so as to learn and grow in different fields.
