Here Joe compares how storytelling impacts brain development with television and other screen based technologies. Critics of TV programs point out the very short attentions spans that are demanded and which trains the child in these very short little bit sound bites and constantly changing imagery and scenarios from one character to another. If we look at the child's total absorption in storytelling, they will sit spellbound for hours and hours as the story telling goes on. They exhibit some of this catatonic spellbound entrancement in front of television because it's substituting and affecting some of the same brain structures.  And so we find their response is the same entrainment, but of course none of this higher cortical structure is called on.
