It may indeed be questioned whether we have any memories at all from our childhood: memories relating to our childhood may be all that we possess. Our childhood memories show us our earliest years not as they were, but as they appeared at the later periods when the memories were aroused. In these periods of arousal, the childhood memories did not, as people are accustomed to say, emerge; they were formed at that time. And a number of motives, with no concern for historical accuracy, had a part in forming them, as well as in the selection of the memories themselves.
