Hey X:
The reviewers didn't lose their ability to focus at all. They just began to focus their attention on the Image Stream instead.
Focus exists as a function of being conscious. Focus consists of how many bits of information you attend to. Focus consists of 7+-2 bits or chunks of attention. Thus, the reviewers began to concentrate on their Image Stream.
It's just like getting stuck on a song you hear on the radio. All it takes is to attend your focus to another song. Eventually, you forget about the first one.
Good luck, and...
