Although most adults lose Eidetic Imagery skills, it can be retained through use and practice.
Because we hear the children frequently repeating out loud bits and pieces of the stories they have heard.
This mental replay gives children more opportunity to draw from this linguistic input, the language principles which they are striving to learn.
Most adults lose eidetic imagery, although it is not necessarily so, and some do retain this skill.
There was a senior professor in our department who read hisreports at faculty meetings from a blank sheet of paper. After I had obtained tenure, I ventured to inquire about the practice.
He explained that he had good eidetic imagery and that it was easy for him to write the reports at home and then glance at a blank sheet during the meeting.
The outline appeared in his mind so clearly in this mind that he need only read it off the blank page.
