When subjects view a picture story, they do have a visual representation of what the pictures look like, in addition to the meaning-based representation. They usually don't remember the visual representation for long, however, largely because when they see the pictures, they are thinking about what they mean in order to understand the story. If, in contrast, they were asked to remember visual details of the pictures and to ignore the story they tell, they would have a better memory for the visual details and the meaning-based representation would be worse.
