Summary:
The authors provide an overview of change blindness understanding, such as how research has shown that change blindness occurs often during eye movement or when a user's attention wanes.

The main contribution of the paper is the idea that change blindness research does not confirm the thought that visual representations of a scene are 'sparse'. The authors propose four requirements for a change blindness to reaffirm the idea of sparse representations:

1. Evidence must eliminate the possibility that detailed visual representations exist by fade from memory before the representations can be compared with others to perceive changes
2. Evidence must eliminate the possibility that detailed visual representations exist, but in a different visual processing section (of the brain?) that cannot compare with the currently viewed representation for change detection
3. Evidence must eliminate the possibility that any stored detailed representation is in a format that cannot be compared with another representation
4. Evidence must eliminate the possibility that both the stored detailed representation and the viewed representation can be compared, but are not for some reason

Discussion:

The paper's final thoughts on how a representation are stored do not concern me. Instead, this paper has a wide bibliography of change blindness research that should help me to look for related work.
